An embodiment of the present invention will now be described with reference to the moving walk shown in Figures 1 to 9. The moving walkway includes many pallets 3 movable on a pair of left and right guide rails 2A and 2B fixedly installed on the frame 1, and handrails arranged along the moving direction of the pallets 3.

The pallets 3 are arranged in a circular manner so that passengers can climb on the advancing side of these pallets, while the return side moves under the advancing side so that it can return to its original position. As shown in FIGS. 3 , 6 and 7 , the pallet 3 generally includes a pallet frame 5 and a main anti-slip strip 6 horizontally installed on the top surface 5U of the pallet frame 5 . The main anti-slip strip 6 is formed by connecting and bending thin steel plates (such as thin stainless steel plates) into a corrugated shape, and when the pallet is fixedly installed on the pallet frame 5, the extending direction of the ridge of the corrugation is in line with the direction of the plate The direction of movement of the table remains the same. The side anti-slip strips 7A and 7B are respectively arranged adjacent to the opposite ends of the corrugations of the main anti-slip strip 6, and the front anti-slip strip 8A and the rear anti-slip strip 8B each have substantially the same cross section as the main anti-slip strip 6, and they Each is provided adjacent to opposite ends of the main anti-slip strips 6 along the moving direction of the pallet, and these anti-slip strips are all fixedly mounted on the pallet frame 5 . The side anti-skid strips 7A and 7B and the front and rear anti-skid strips 8A and 8B have a different color (for example, yellow, which has an attention-grabbing effect) than the main anti-skid strip 6, and may be molded from a synthetic resin material, for example.

The main anti-slip strip 6 can be made by molding an aluminum alloy material into a corrugated shape.

A rotary shaft 9 extends in the width direction of the pallet 3 via bearings 9B, and front wheels 10A and 10B are respectively fixed on opposite ends of the shaft. The rear wheels 11A and 11B are rotatably supported on the pallet frame 5 and spaced apart from the front wheels 10A and 10B in the moving direction. The front wheels 10A and 10B and the rear wheels 11A and 11B roll on the guide rails 2A and 2B respectively, there is no part connecting the pallets to each other between adjacent pallets 3 and each pallet 3 can move freely.

As shown in FIG. 3 , a power conversion mechanism for changing the direction of the transmitted driving force and a speed conversion mechanism for changing the speed of the transmitted driving force are provided in the middle of the rotating shaft 9 . In this power conversion mechanism and this speed conversion mechanism, a keyway hub 12 having an engaging portion formed of grooves and protrusions extending in the axial direction on its outer peripheral surface is fixedly installed on the rotating shaft 9 On the middle part of the hub 12, and a rotating part 13 engages with the engaging part of the keyway hub 12 so that the rotating part 13 can only move in the axial direction. The rotary member 13 is composed of a pair of rotary elements 13A and 13B, and inclined surfaces 13a and 13b are respectively provided on their opposite faces. The spring seats 14A and 14B are fixedly mounted on the rotating shaft 9 and are each spaced a predetermined distance from the pair of rotating members 13A and 13B. A thrust spring 15A is provided between the spring seat 14A and the rotary member 13A, and a thrust spring 15B is provided between the spring seat 14B and the rotary member 13B, thereby urging the pair of rotary members 13A and 13B toward each other. When the pair of rotating members 13A and 13B contact each other, a V-shaped groove is formed by the two slopes 13a and 13b.

As shown in Figures 6 and 7, all elongated plates 16 are pivotally connected to the rear end of the pallet 3 in the direction of movement by respective pins 17 on their one ends, and likewise, a partition 18 is arranged on the elongated The long plate 16 is connected underneath and by pins 17 to the rear end. The other end portions of the elongated plate member 16 and the partition plate 18 are reversibly inserted into the pallet 3 adjacent rearward in the moving direction. In other words, the elongated panels 16 can each be inserted backwards into the spaces 6H formed by the corrugations of the main anti-slip strip 6 and the top surface 5U of the panel frame 5 . The partition plate 18 can be inserted backward into guide grooves 19A and 19B provided under the top surface 5U of the pallet stand 5 .

Next, a power transmission mechanism for moving the pallet 3 constructed as described above will be described. As shown in FIG. 2, an annular power transmission member 20 is arranged under the advance side of a row of pallets 3 along the entire length thereof. The power transmission member 20 includes friction members 21 of trapezoidal cross-section, which have slopes 21a and 21b similar to the slopes 13a and 13b of the pair of rotating elements 13A and 13A, and a chain 22 which separates the trapezoidal friction members from each other. The connection portions 21c protruding from the bottom of the 21 are interconnected. The power transmission member 20 extends around the driving wheel 23 and the driven wheel 24 between the driving wheel 23 and the driven wheel 24 mounted on the frame, the advancing side of this power transmitting member is arranged in opposite relation to the advancing side of the pallet 3 . The driving wheel 23 has a sprocket 25A installed coaxially therewith, and the rotational force of the motor 26 will be transmitted to the driving wheel through the driving chain 25B. The driven wheel 24 is supported on the supporting frame 24S and can move in the direction of chain tension to absorb the elongation of the chain 22. This driven wheel is usually tensioned in the direction of tension by an elastic member 27 in the direction of tension. The power transmission member 20 is guided by guide rails 28 so that it can be in opposing relation to the advancing side of the pallet 3, and so that the friction member 21 can be fitted in a V-shaped groove formed by a pair of rotating members 13A and 13B. The guide rail 28 is fixedly installed on the frame 1 to guide the movement of the chain 22 . The guide rails have different heights at the entrance and exit sections where passengers board and exit the moving walkway and at the middle section of the moving walkway. More specifically, as shown in Figure 2, the track has a rising slope or an angle S in the direction of motion near the entrance portion, maintains the height of the upper portion of the slope in the middle portion, and has a slope near the exit portion. The slope or angle of inclination S of the descent. Therefore, the height of the track is changed. Due to the change of the height of the guide rail 28, the guided power transmission member 20 is also moved up and down relative to the direction of motion. The contact position of the groove changes. In other words, the position where the power is transmitted to the pallet 3 or the position where the power is received changes with the movement of the pallet 3 .

The case where the mobile handrail 4 is guided and driven will be described below. The moving handrail 4 has a C-shaped cross section and is moved along the railing member by a guide 29G (see FIG. 1 ) mounted on the upper end portion of the railing member 29 . As shown in FIGS. 8 and 9 , the handrail 4 includes a plurality of handrail elements 30 and gap blocking members 31 (such as telescoping hoses or bellows) for absorbing gaps between adjacent handrail elements 30 changes to bridge this gap. Each handrail member 30 includes a tongue-shaped member 32 extending downward from the central portion of its inner surface, a plurality of holes 33 that are elongated in the direction of movement and juxtaposed along the C-shaped cross-section and can The positioning bar 34 is inserted back into the hole 33 of the adjacent balustrade element 30 .

Tongue 32 rotatably supports a pair of vertically spaced guide rollers 35A and 35B which grip a guide rail 36 fixedly secured to frame 1 . Tongue 32 pivotally supports one end of first and second links 37A and 37B of the same length at the same location. The other ends of the two links 37A and 37B are pivotally connected to the driving member 38 . The first side bar 37A is pivotally connected to the drive member 38 at the same location as the second link 37B on the adjacent tongue 32 so that these links form a continuous whole in a zigzag pattern. The drive member 38 rotatably supports a pair of vertically spaced guide rollers 39A and 39B which clamp a guide rail 40 fixedly mounted on the frame 1 . The fixed position of guide rail 40 is changed, so that the spacing H ₁ , H ₂ between guide rails 36 and 40 becomes smaller gradually in the direction of motion near the entrance portion, maintains this small spacing in the middle portion, and keeps this small distance in the middle portion, while at the exit The vicinity of the part gradually becomes larger, and this change corresponds to the change in height of the guide rail 28 of the chain 22 above.

The drive member 38 is provided with a spacer 41 having such a length that this spacer 41 comes into contact with the adjacent drive member 38 when the distance between the guide rails 36 and 40 is at a maximum. An elastic member 42 made of rubber or the like is mounted on the end of the spacer 41 to provide a cushioning effect when the spacer comes into contact with the contact member 38 . A protruding portion 43 is formed on the spacer 41 . As shown in FIG. 2, the protruding portion 43 is engaged with handrail driving means 44A and 44B provided at opposite end portions of the handrail forming member to drive the handrail 4. As shown in FIG. The handrail driving devices 44A and 44B each include a motor 45 , a rotating chain 46 transmitting the power of the motor, and a sprocket 47 rotated by the chain 46 and having teeth engageable with the protruding portion 43 .

The work of the moving walk of above-mentioned structure is described below.

First, when the pallet 3 is in the acceleration zone A shown in FIG. 2 with a rising slope, the friction member 21 of the power transmission member 20 is in contact with the outside of the V-shaped groove formed by the rotating elements 13A and 13B, as shown in FIG. 3 Show. In this case, when the friction member 21 is driven in a direction opposite to the moving direction of the pallet, that is, in a direction from the outlet side to the inlet side, the rotating elements 13A and 13B that are in contact with the friction member start to be driven by the friction force. turned. The rotary elements 13A and 13B thus function as a power conversion mechanism that converts the driving force in the above-mentioned one direction into a rotary force. By the rotation of the rotation elements 13A and 13B, the front wheels 10A and 10B are driven, so that the pallet 3 is run. Because the power transmission member 20 is guided by the guide rail 28 into the ascending slope, the friction member 21 forces the V-shaped groove to open against the thrust of the thrust springs 15A and 15B that close the rotating elements 13A and 13B together, as shown in Figures 4 and 13B. 5 and is thus forced into the radially inward position of the V-shaped groove. As a result, the contact position of the friction member 21 with the rotating elements 13A and 13B (that is, the position of power transmission) changes from radially outward to radially inward, so that the rotation speed of the rotating elements 13A and 13B is relatively high relative to that driven at a constant speed. The friction member 21 becomes gradually larger, so the moving speed of the pallet 3 also becomes larger and larger. Like this, the inclined surfaces 13a and 13b that form V-shaped groove have just constituted a rotating speed conversion mechanism that makes the rotating speed of front-wheel 10A and 10B change, and a moving speed converting mechanism that makes the moving speed of pallet change and a driven power transmission The driving speed conversion mechanism that changes the driving speed transmitted by the component 20. The running speed of the pallet 3 becomes higher in the acceleration zone A, and in the case of high speed, the pallet 3 runs with adjustment in the high-speed zone B in the middle part, and then enters the deceleration zone C near the exit. In the deceleration zone C, the friction member 21, which remains in contact with the inside of the V-shaped groove formed by the rotating elements 13A and 13B, gradually moves to the outside of the V-shaped groove, as shown in Figures 5, 4 and 3, thus making the front wheels 10A and The speed of 10B is gradually reduced.

As mentioned above, pallet 3 is gradually accelerated from the safe speed for passengers to step on the self-walking path near the entrance, maintains the accelerated maximum speed in the middle part, and is then decelerated near the exit, from the maximum speed to Passengers leave the moving walkway at a safe speed. Thus, a variable speed travelator is obtained in which the travel speed of the pallets is maximum in the middle of the traveler. In addition, since the pallet 3 can be driven at a variable speed by a simple power transmission mechanism provided on the entire length of the pallet 3 in the moving direction and a speed conversion mechanism provided on the pallet 3, it is not necessary to A variable-speed moving walkway with a simple structure can be obtained by using a complicated link mechanism.

In the acceleration zone A and the deceleration zone B, the speeds of the pallets 3 are different from each other, so a gap is formed between adjacent pallets 3, but since many elongated members 16 which can be received backwards are placed here There is no danger of falling between the pallets even if passengers walk on them. Since gaps are formed between adjacent elongated rods 16, the interior of frame 1 can be seen through these gaps. But the partition 18 blocks the view so that it cannot be seen, and together with the elongated member 16 closes the gap between the pallets 3 .

On the other hand, as described above for the driving of the pallet 3, the moving handrail 4 is driven at different speeds corresponding to the acceleration zone A, the high speed zone B and the deceleration zone C. In order to implement this speed control, the distance between the two guide rails 36 and 40 can be changed to change the angles θ ₁ and θ ₂ between the first link 37A and the second link 37B, thereby moving the distance between the holding elements 30 The gap varies from a small value L ₁ to a large value L ₂ . More specifically, when the distance between the guide rails 36 and 40 is a large distance H ₁ , the angle between the first link 37A and the second link 37B is a small angle such as θ ₁ , at this time, the handrail element 30 The gap in between is the distance L ₁ , in which case the bridging member 31 shrinks the most. On the contrary, when the interval between the two guide rails 36 and 40 is a small interval H ₂ , the angle between the first link 37A and the second link 37B is a large angle such as θ ₂ , at this time, the distance between the handrail elements 30 The gap is the maximum distance L ₂ , in which case the bridging member is maximally expanded. By changing the gap between the handrail elements 30 in this way, the moving speed of the handrail elements 30 can be varied. Of course, the spacing between the two guide rails 36 and 40 is gradually changed to ensure that no sudden changes in speed occur.

If the moving speed of the handrail element 30 is not synchronized with the moving speed of the pallet 3, then this will lead to serious accidents in which passengers fall. Therefore, a synchronizing device is also provided to keep the moving speed of the handrail element 30 in sync with the moving speed of the pallet 3, but this synchronizing device is not shown in the figure.

Although the aforementioned moving handrail 4 is driven by a connecting rod, the handrail element 30 can also use the same driving structure as the pallet 3 so as to be driven by a similar power transmission mechanism.

In the above embodiments, only one power transmission mechanism is used for the entire length in the moving direction of the pallet. FIGS. 10 to 12 show another embodiment in which the pallet is moved by a plurality of power transmission mechanisms. That is, a plurality of disks 48A to 48B are installed on the rotating shaft 9 of the front wheels 10A and 10B of each pallet 3, and a plurality of power transmission mechanisms 49A, 50A, 52A, 53, 52B, 51B, 50B and 49B It is mounted on the frame 1 in an opposing relationship with the disc. Among the plurality of power transmission mechanisms, power transmission mechanisms 49A and 49B that transmit safe moving speeds for passengers boarding and leaving the moving walkway are respectively provided at the entrance and exit, and compared with the moving speeds of the power transmission mechanisms 49A and 49B , the power transmission mechanisms 50A, 51A, and 52A that gradually increase the moving speed are provided in the acceleration area of the pallet. In addition, power transmission mechanisms 52B, 51B and 50B for gradually reducing the moving speed are provided in the deceleration area of the pallet, and a power transmission mechanism 53 for continuously transmitting the maximum moving speed is installed in the area between the acceleration area and the deceleration area. For example, as shown in FIG. 12, the power transmission mechanisms 52A, 53 and 52B arranged adjacent to each other are arranged in a manner of partially overlapping 1 in the moving direction of the pallet, thereby ensuring that power can always be transmitted to the pallet. superior. Each power transmission mechanism includes a ring-shaped power transmission member 54 and a pair of rotatable pulleys 55A and 55B. The power transmission member 54 surrounds the pulley and moves the power transmission member 54 through the pulley. One of the pair of pulleys 55A and 55B serves as a driving pulley for moving the power transmission member 54 . Reference numerals 56 and 57 denote pulleys around which the power transmission members 54 of the adjacent power transmission mechanisms 52A and 52B respectively pass.

Now the moving mode of pallet 3 in the above-mentioned structure is described. At initial operation, all power transmission mechanisms are driven so that the power transmission members 54 all move at their respective predetermined speeds. In this case, the pallet 3 positioned at the entrance is in a relationship corresponding to the power transmission mechanism 49A. At this time, the disk 48E contacts the power transmission member 54 of the power transmission mechanism 49A to generate frictional force. turn. With this rotational force, the front wheels 10A and 10B are rotated via the rotary shaft 9 to roll on the guide rails 2A and 2B, thereby moving the pallet 3 . Then, when the pallet 3 reaches the position of the power transmission mechanism 50A, the disc 48D of the pallet 3 enters into a position in contact with the power transmission member 54 of the power transmission mechanism 50A, and after the pallet moves through the overlapping distance 1, the circular disc 48D The disc 48E is disengaged from the power transmission member 54 of the power transmission mechanism 49A. Within the overlapping distance, the power is transmitted to the two disks 48E and 48D at different speeds from the power transmission members 54 of the power transmission mechanisms 49A and 50A, and the speed difference at this time can pass through the two disks 48E and 48D The slippage between each of the and the power transmission member 54 is absorbed. Thus, the pallet 3 is accelerated, receiving power from a plurality of power transmission mechanisms that sequentially increase the speed of movement (movement) of the power transmission mechanisms. In the region of the power transmission mechanism 53, the pallet runs at maximum speed, then the pallet decelerates, receiving power from the power transmission mechanism which causes a sequential reduction in the speed of movement, contrary to the above, to reduce the speed of movement to substantially The same speed as the import department.

In addition, in the above-described embodiments, the moving speed of the pallet 3 can also be increased or decreased by a simple mechanism.

Figure 13 shows another embodiment of the present invention. More specifically, a rotary member 58 having a tapered surface on its outer peripheral surface is mounted on the rotary shaft 9 of the pallet 3, and a power transmission member 60 of a power transmission mechanism is mounted in an opposing relationship with the tapered surface 59 . The power transmission member 60 is provided over the entire length, and the transmission speed of power is constant. Therefore, in order to change the rotation speed of the rotating member 58, the power transmission member 60 moves to the position shown by the dotted line through the guide rail (not shown in the figure), and the guide rail is used to guide the power of the power transmission member 60, thereby to The position of contact between the power transmission member 60 and the tapered surface 59 in the acceleration zone and deceleration zone of the pallet is changed. In the above structure, at the entrance and exit of the passenger boarding or leaving the moving walkway, the power transmission member 60 is in contact with the outer peripheral surface of the tapered surface 59 of the rotating member 58, so that the rotation speed of the front wheels 10A and 10B is reduced, and when the contact position When turning radially inwardly of the tapered surface 59, the rotational speed of the front wheels 10A and 10B is gradually increased, and the moving speed of the pallet 3 is changed in this manner.

Incidentally, in each of the above-mentioned embodiments, although the transmission force is transmitted by friction between the power transmission member of the power transmission mechanism and the rotating member of the pallet, the friction force can also be replaced by an engagement force, and the engagement force can be used to replace the friction force. power to transmit. More specifically, as shown in FIG. 14, the power transmission member 61 of the power transmission mechanism is in the form of a chain like a chain, and the sprockets 62A and 62D engaging this power transmission member are mounted on the rotating shaft of the pallet 3. 9 on. The diameters of the sprockets 62A to 62D are different from each other, and the power transmission member 61 engages with the sprockets 62A to 62D sequentially, thereby changing the moving speed of the pallet 3 . 10 to 12, when the power transmission member 54 is in the form of a chain, and when the discs 48A to 48E are replaced by sprockets, the same effect can be obtained. In addition, the power transmission member may be a member having a plurality of teeth constituted by concave and convex portions like a timing belt, in which case, a gear meshing with these teeth is mounted on a rotating shaft, thereby transmitting power.

The transmission of power from the transmission mechanism to the pallet is realized by using engagement transmission instead of friction transmission, so that the power can be transmitted reliably.

Although the above-mentioned embodiments are all described for a horizontally arranged moving walkway without steps on the advancing side of the pallet, the present invention can also be applied to an inclined moving walkway, and can also be applied to a moving walkway with steps on the advancing side pallet. level on the escalator. That is to say, compared with the moving walkway, the pallets of the escalator run obliquely, but these pallets can also be driven by the mechanism described in the above embodiments, and when the moving speed increases the gap between adjacent pallets is widened. , the lifting device arranged at the rear end of the pallet tilts, and its length in the height direction is variable, thereby closing the gap between adjacent pallets. Alternatively, bridges can also be used instead of the lifting device.

In the above embodiments, although each power conversion mechanism (or rotational speed conversion mechanism or movement speed conversion mechanism) uses a power transmission mechanism in an opposite relationship with it, it is also possible to combine a plurality of such power transmission mechanisms with multiple Two such power conversion mechanisms (or rotating speed conversion mechanisms or moving speed conversion mechanisms) are used in groups, thus obtaining variable-speed pallet-type passenger moving walkways.
