Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an escalator device, and more particularly, to a step circulation system and its mechanism.
[0002]
[Prior art]
FIG. 22 is a partially cutaway perspective view showing the structure of a conventional escalator device, and FIG. 23 is a schematic side view thereof. The electric motor 102 in the upper machine chamber 108a rotates the step drive sprocket 109a via the speed reducer 101 and the drive chain 103 connected thereto. An endless step chain 105 is stretched between the step drive sprocket 109a and the step drive sprocket 109b of the lower machine chamber 108b. On the other hand, a roller 110 is rotatably provided on a step 104 on which a passenger rides and travels along a step rail 106 by a step chain 105. Further, the moving handrail drive wheel (not shown) is rotated from the step driving sprocket 109a via the moving handrail drive chain (not shown), and the moving handrail 107 and the step 104 are driven in synchronization.
[0003]
[Problems to be solved by the invention]
In order to circulate the step 104, the step 104 is wound around the step drive sprockets 109a and 109b and turned back, but at this time, the folded circular trajectory is such that the creep riser 111 forming the step side surface between adjacent steps does not interfere with each other. Must have a sufficiently large diameter R (see FIG. 23).
[0004]
Accordingly, the machine rooms 108a and 108b need a depth h corresponding to the machine rooms 108a and 108b, and occupy a large space. For this reason, it is necessary to increase the floor thickness on the building side in order to embed the machine room. Moreover, an escalator device cannot be additionally introduced into an existing building with a small floor thickness for the same reason as described above. Furthermore, not only the machine room portion but also the slope portion becomes thick, and the landscape occupies a large space because this slope portion occupies a large space.
[0005]
This invention is made | formed in view of the said actual condition, and it aims at providing the escalator apparatus which can reduce the thickness of the up-down direction of the whole apparatus.

[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0009]
[Pallet circulation method]
First, the pallet circulation method in the escalator apparatus according to the present invention will be described with reference to FIGS. 1 to 3 schematically showing the operation of the pallet.
[0010]
In the following, the upper side of the track 1 (the route from the lower left to the upper right in FIG. 1) is referred to as “outward route (2)”, and the lower side (the route from the upper right to the lower left in FIG. 1) is referred to as “return route (3)”. I will call it. Hereinafter, the direction is defined as indicated by the arrows in FIG. In other words, when the passenger stands at the landing on the lower floor and looks at the upper floor, the direction to the upper floor is “front”, the opposite direction is “rear”, and the right and left are “right” The “left side”, the upper side in the vertical direction will be called “upper side”, and the opposite will be called “lower side”.
[0011]
As shown in FIG. 1, the pallets 9 for carrying passengers have a flat plate shape, and are arranged endlessly along the track 1 at an equal pitch. The pallet 9 carries passengers based on the circulation principle described below.
[0012]
That is, first, at the landing 6 of the lower floor portion 5, there is no step between each of the adjacent pallets 9, ..., 9 and a horizontal plane is formed. As the pallet 9 moves along the curved section that moves to the inclined section of the forward path 2, the step between the pallets 9 and 9 increases to form a staircase and rise. At this time, the individual pallets 9,..., 9 move in a state in which the posture is maintained so that the upper surface, that is, the tread surface is horizontal. When the pallet 9 approaches the upper floor portion 4 and enters a curved section where the pallet 9 moves to the horizontal section, the steps between the individual pallets 9 are reduced, and a plurality of pallets 9,. Becomes level again, and passenger 8 gets off here.
[0013]
Thereafter, the pallet 9 moves from the forward path 2 to the return path 3. FIGS. 2A to 2F sequentially show the moving direction reversal operation of the two adjacent pallets 9 and 9 in the upper floor portion 4. In the following description, the preceding pallet 9 (a hatched pallet) is referred to as “front pallet 10”, and the pallet 9 (a pallet without hatching) that follows the front pallet 10 adjacent to the front pallet 10 is referred to as “rear pallet”. 11 ”. 2A to 2F, the pallet 9 further preceding the front pallet 10 is indicated by a broken line.
[0014]
In the horizontal section, the front pallet 10 and the rear pallet 11 that are adjacent to each other are both in a horizontal state and are not stepped from each other (see FIG. 2A). Thereafter, when the front pallet 10 enters the turning section, the rear side of the front pallet 10 falls and starts to tilt (see FIG. 2B).
[0015]
Further, when the front pallet 10 and the rear pallet 11 are both advanced, and when the front pallet 10 is inclined and the gap 12 with the rear pallet 11 is sufficiently opened (see FIG. 2C), the front pallet 10 The moving speed in the horizontal direction decreases, and instead the moving speed in the downward direction increases (see FIG. 2D).
[0016]
When the front pallet 10 moves to the return path along the semicircular curved portion of the turn-back operation section, the horizontal movement direction of the front pallet 10 is reversed and the front pallet 10 moves backward ( (Refer FIG.2 (e)). Then, the front pallet 10 returns to the horizontal posture again, and is positioned in front of the further preceding pallet indicated by the broken line (backward in the traveling direction) (right direction in FIG. 2). During the reversing operation of the front pallet 10, the tread surface of the front pallet 10 remains facing upward. At this time, since the front pallet 10 is already positioned sufficiently below the rear pallet 11, the pallets 10 and 11 do not interfere with each other.
[0017]
Then, the front pallet 10 is guided to the lower floor through the return path (see FIG. 2F). As shown in FIG. 1, the pallet passing through the return path 3 travels in a state where the tread surface is inclined at the same angle as the inclination angle of the return path 3 of the track.
[0018]
Next, the pallet folding operation in the lower floor 5 will be described with reference to FIG. In FIG. 3A, the pallet is located on the return path 3, and at this time, both the pallets are moving backward (leftward in FIG. 3).
[0019]
When both pallets 10 and 11 further advance, first, the front pallet 10 is inclined so that the rear side sinks (see FIG. 3B). Eventually, the rear pallet 11 also inclines (see FIG. 3C), and the front pallet 10 reaches the semicircular curved portion of the turning section of the track and starts to rise (see FIG. 3D).
[0020]
Further, when both pallets 10 and 11 move, the horizontal movement direction of the front pallet 10 is reversed, and the front pallet 10 moves up while moving to the front side (see FIG. 3E). At this time, the front pallet 10 and the rear pallet 11 do not interfere with each other because both move in a posture inclined with respect to the horizontal plane.
[0021]
Eventually, the front pallet 10 passes through the semicircular curved portion of the track while shifting from the inclined state to the horizontal state, and transitions to the straight portion (horizontal section) of the forward path 2 (see FIG. 3 (f)). .
[0022]
When the pallet further moves, it reaches the inclined section of the forward path 2, and the front pallet 10 rises relative to the rear pallet 11 to form a staircase (see FIG. 3 (g) and FIG. 1).
[0023]
The above operations occur continuously and the pallet circulates. Note that when the passenger is transported from the upper floor to the lower floor, the operation is reversed.
[0024]
[Configuration of pallet and guide rail]
Below, the several mechanism for implement | achieving said circulation system is demonstrated in order. First, the configuration of the pallet and the guide rails that determine its posture and movement path will be described with reference to FIGS.
[0025]
FIG. 4 is a schematic perspective view of the pallet 9 and its accessory parts. The pallet 9 is a substantially flat plate-like body, and the upper surface thereof is a tread surface 14. The pallet 9 is provided with a shaft 15 projecting outward in the horizontal direction from both lateral side surfaces thereof. A rear roller (guide roller) 16 is rotatably attached to the tip of each shaft 15. Each shaft 15 is provided with a bar 18 that protrudes obliquely forward in the upward direction from the intermediate portion thereof, and a front roller 17 is rotatably attached to the tip of the bar 18.
[0026]
5 and 6 are schematic perspective views of a guide rail that is a track for causing the pallet 9 to travel along a main frame, that is, a truss (not shown), and FIG. 5 is a guide of the upper floor portion of the escalator device. FIG. 6 shows a guide rail in the lower floor portion of the escalator device.
[0027]
Each of the rear roller guide rail 19 and the front roller guide rail 20 has a U-shaped cross section. The rear roller guide rail 19 opens toward the passage through which the pallet 9 passes, and the front roller guide rail 20 opens in the direction opposite to the rear roller guide rail 19. The front roller guide rail 20 has a “<”-shaped cross-section in which the lower end surface is removed from the “-”-shaped cross-section in the inclined portion of the forward path.
[0028]
Normally, the rear roller guide rail 19 has its curvilinear portion removed as shown in FIGS. 8, 9 and 11 in order to prevent interference with the step chain drive sprocket that drives the pallet. Although not necessarily required to be removed), the rear roller 16 is guided by the chain moving along the sprocket at the curved portion. However, in FIG. 5 and FIG. 6, the rear roller guide rail 19 is shown in a state where the curved portion of the folded section is not removed in order to facilitate understanding of the configuration of the present embodiment.
[0029]
The front roller guide rail 20 is always arranged vertically above the rear roller guide rail 19 in all sections of the forward and backward paths 2 and 3, and the guide rails in the upper floor portion and the lower floor portion are respectively provided. Is bent 180 degrees and folded back to form an endless track.
[0030]
In both the upper floor portion and the lower floor portion, the folding curve portion (semicircular curve portion) of the rear roller guide rail 19 is behind the folding curve portion (semicircular curve portion) of the front roller guide rail 20. Is more arranged. Then, the pallet 9 is guided by each guide so that the rear roller 16 rolls along the groove portion of the rear roller guide rail 19 and the front roller 17 rolls along the groove portion of the front roller guide rail 20. It is mounted on the rail in a rolling manner.
[0031]
At this time, the front roller guide rail 20 and the rear roller guide rail 19 are provided such that their relative positions are as described below.
[0032]
That is, in the horizontal section 23 of the forward path on the upper floor side and the horizontal section 30 of the forward path on the lower floor side, the relative distance between the front roller guide rail 20 and the rear roller guide rail 19 in the vertical direction is It is arranged so as to be equal to the height difference between the front roller 17 and the rear roller 16 when the tread surface 14 is horizontal.
[0033]
In the transition section (curve section) that transitions from the horizontal section of the forward path to the inclined section, the relative distance between the front roller guide rail 20 and the rear roller guide rail 19 (the relative distance here is not related to the vertical direction). The shape of the curved portion of the rail is changed so that the shortest distance is gradually shortened.
[0034]
In the inclined section 24, the relative distance between the front roller guide rail 20 and the rear roller guide rail 19 is set so that the tread surface 14 is horizontal.
[0035]
In the upper floor portion, as shown in FIG. 5, the front roller guide rail 20 is bent in the upward direction at one end just before reaching the curved portion that turns back from the forward path 2 to the backward path 3, and then the pallet inclination guide curve portion 25. Is formed, and then the curved path leading to the return path 3 is formed in the downward direction. That is, in the inclination guide curve portion 25 of the front roller guide rail 20, the distance between the front roller guide rail 20 and the rear roller guide rail 19 continuously changes (becomes wider).
[0036]
In the lower floor portion, as shown in FIG. 6, the front roller guide rail 20 bends upward and downward in the return section to form a pallet inclination guide curve portion 32, and then becomes horizontal and becomes the lower floor. After the floor return path side horizontal section 31 is formed, it is bent upward to form a semicircular curved track to the forward path 2.
[0037]
Further, the front roller guide rail 20 is provided with a slit 21a in the upper floor portion as shown in FIG. 5, and a slit 21b in the lower floor portion as shown in FIG. The slits 21a and 21b are formed at the portion where the rear roller guide rail 19 and the front roller guide rail 20 intersect when the guide rails 19 and 20 are viewed from the side (projection from the left and right direction to the vertical surface). The front roller guide rail 20 is provided so as to overlap with the movement locus of the 16 shafts 15. The widths of the slits 21 a and 21 b are set to be larger than the shaft 15 and sufficiently smaller than the diameter of the front roller 17.
[0038]
Next, the attitude control of the pallet 9 based on the cooperative action of the guide rails 19 and 20 and the front and rear rollers 16 and 17 will be described in detail.
[0039]
First, attention is paid to the pallet 9 in the inclined section of the forward path 2 when the escalator device is driven in the upward direction (see FIG. 5). In this section, the load of the pallet 9 is received by the rear roller 16, and the moment received by the pallet 9 is received by the front roller 17. That is, the pallet has the front roller 17 on the front side with the rear roller 16 as a fulcrum, and the step surface 14 on the rear side. Therefore, the load applied to the step surface 14 becomes a moment with the rear roller 16 as a fulcrum. The roller 17 is pushed upward. The front roller 17 is supported by the front roller guide rail 20 from above and receives the moment.
[0040]
In this section, the distance between the front roller 17 and the rear roller 16 in the direction perpendicular to the tread 14 is the same as the distance between the front roller guide rail 20 and the rear roller guide rail 19 in the vertical direction. The pallet 9 ascends along the guide rail while keeping the step surface 14 horizontal.
[0041]
In the vicinity of the upper floor, the pallet 9 transitions from an inclined movement to a horizontal movement according to the curved shape of the guide rails 19 and 20. In the landing 7 on the upper floor, a horizontal plane is formed by a plurality of pallets 9 so that passengers can easily get on and off.
[0042]
The pallet 9 that is moving in the horizontal direction at the landing 7 eventually sinks under the comb floor plate 22a, is cut off from the outside, and is guided to a machine room (not shown).
[0043]
Thereafter, the front roller 17 rises along the pallet inclination guide curve portion 25 of the front roller guide rail 20, so that the pallet 9 is inclined so as to sink its rear side. The posture at this time corresponds to (b) to (c) of FIG.
[0044]
Further, the pallet 9 advances, and the rear roller 16 shifts to the semicircular curved portion of the rear roller guide rail 19. At this time, the front roller 17 simultaneously changes to the semicircular curved portion of the front roller guide rail 20. When shifting, the entire pallet 9 begins to move downward (Y negative direction) and sinks (corresponding to FIG. 2D).
[0045]
As the rear roller 16 and the front roller 17 move along the semicircular curved portions of the guide rails 19 and 20, the movement direction of the pallet 9 changes to the X negative direction (corresponding to FIG. 2 (e)).
[0046]
In the vicinity of the position where the moving direction of the pallet 9 is reversed, the shaft 15 that supports the rear roller 16 passes through the slit 21 a of the front roller guide rail 20 and crosses the front roller guide rail 20. Thereafter, when the pallet 9 further moves and the front roller 17 rolls in the return path of the front roller guide rail 20, the width of the slit 21a is sufficiently smaller than the diameter of the front roller 17, so the front roller 17 is used for the front roller. It passes over the slit 21a without dropping from the guide rail 20. The pallet 9 is guided to the return path 3 and circulated back.
[0047]
Next, the direction changing operation of the pallet at the lower floor will be described with reference to FIGS.
[0048]
When the front roller 17 of the pallet 9 that has moved to the lower floor through the return path 3 enters the pallet inclination guiding curve portion 32, the front roller 17 rises, so that the rear surface of the tread 14 of the pallet 9 sinks. To tilt. This state corresponds to the state of the front pallet 10 in FIG. Thereafter, the pallet 9 moves in the negative X direction while maintaining a constant distance in the vertical direction between the front roller 17 and the rear roller 16 in the lower floor return home side horizontal section 31 (corresponding to FIG. 3C).
[0049]
When the pallet 9 further advances, the front roller 17 and the rear roller 16 reach the semicircular curved portions of the guide rails 19 and 20, and the pallet 9 rises in an inclined posture (FIGS. 3D to 3E). Equivalent). Then, the pallet 9 reverses the horizontal movement direction and starts moving in the X positive direction. At this time, since the adjacent pallets are inclined, they do not interfere with each other.
[0050]
In the process of passing through the semicircular curved portion, the front roller 17 rolls along the front roller guide rail 20 and gets over the slit 21b. In the process in which the front roller 17 exits the semicircular curved portion of the front roller guide rail 20, the pallet 9 in the inclined posture gradually shifts to the horizontal posture.
[0051]
The shaft 15 passes through the slit 21b after the pallet 9 further moves. When the pallet 9 further advances, the pallet 9 is exposed from the comb floor plate 22b of the lower floor to form a horizontal portion for passengers to get on and off.
[0052]
The pallet 9 moves along the guide rails 19 and 20 while maintaining the horizontal state from the horizontal part to the inclined part of the forward path, and each pallet 9 forms a stepped surface.
[0053]
As described above, in the present embodiment, the two guide rollers 17 and 16 are provided at different positions with respect to the pallet 9, and the circulation paths (movement trajectories) of the guide rollers 17 and 16 have a predetermined positional relationship. The posture of the pallet 9 is controlled by being determined by the two guide rails 19 and 20 arranged. By appropriately determining the relative positional relationship between the guide rails 19 and 20, (1) in each section of the forward path, the tread surface 14 of the pallet 9 can be moved while being kept horizontal, and (2) at the end of the truss. In the pallet folding section, the moving direction of the pallet 9 can be continuously reversed while avoiding interference between adjacent pallets by appropriately tilting the pallet 9 without inverting the top of the pallet 9. For this reason, it is possible to reduce the space required for folding the flat plate-like pallet, and to reduce the machine room and the truss of the inclined portion.
[0054]
The above is the basic operating principle of the escalator device according to the present invention. Hereinafter, details of the escalator device according to the present invention will be described in more detail.
[0055]
[Pallet drive mechanism]
First, the pallet driving mechanism will be described with reference to FIGS.
[0056]
FIG. 7 is an enlarged cross-sectional view of the rear roller guide rail 19. A rear roller 16 is rotatably mounted on a shaft 15 protruding from a pallet (not shown) via a bearing 38. The rear roller 16 is engaged with the groove 36 of the rear roller guide rail 19.
[0057]
The chain (step chain) 33 is configured by alternately connecting chain links 34 and tune pins 35. The chain 33 is provided endlessly along the inside of the rear roller guide rail 19.
[0058]
The pallet 9 not shown in FIG. 7 is connected to the chain 33 via the shaft 15 and the connector 39. The coupler 39 connects the shaft 15 and the chain 33 so as to be rotatable and detachable. A plurality of pallets 9,..., 9 are connected to the chain 33 via the respective shafts 15,. That is, the pallets 9 are arranged in an endless belt form along the rear roller guide rail 19.
A plurality of auxiliary wheels 37 are provided at intervals on the inner side of the curve in a section where the rear roller guide rail 19 is bent (for example, a transition from a skew section to a horizontal section).
[0059]
FIG. 8 is a perspective view schematically showing a drive mechanism of the chain 33 in the machine room on the upper floor side. As described above, the rear roller guide rail 19 terminates in front of the sprocket 40, but the chain 33 extends further than the rear roller guide rail 19 and is hung on the sprocket 40. .
[0060]
The sprocket 40 is rotatably disposed in a truss (not shown) by a bearing (not shown). A pulley 41a (timing pulley 41a in this example) is coaxially fixed to the pulley 40 (sprocket 40 in this example).
[0061]
On the other hand, a motor 44 provided with a reduction gear 43 is fixed to a truss (not shown). The drive shaft of the motor 44 is supported by a pair of bearings 46, 46, and a pulley 41b (timing pulley 41b in this example) is fixed to the tip thereof. A belt 42 is wound around the pulleys 41a and 41b.
[0062]
Therefore, when the motor 44 rotates, the driving force is transmitted in the order of the speed reducer 43, the pulley 41b, the belt 42, and the pulley 41a to rotate the sprocket 40. Then, the sprocket 40 pulls the chain 33 and moves it along the rear roller guide rail 19. The chain 33 further pulls the shaft 15 of each pallet 9, the rear roller 16 rolls in the guide rail while engaging with the groove 36 of the rear roller guide rail 19, and the pallet 9 moves.
[0063]
In the section where the guide rail has a curved shape at the transition between the inclined section and the horizontal section, the chain 33 is guided in contact with the auxiliary wheel 37, and the chain 33 directly interferes with the inner wall of the guide rail 19 for the rear roller. prevent. For this reason, generation | occurrence | production of the vibration by noise generation | occurrence | production prevention, protection of a guide rail, and a chain pulsation can be suppressed.
[0064]
The chain / sprocket may be changed to a pulley / belt, or a drive system may be configured by directly connecting a direct drive motor or the like to the sprocket instead of the pulley 41b, belt 42, and pulley 41a. .
[0065]
[Pallet feeding mechanism in folding section]
Next, the constant speed feeding mechanism of the pallet 9 in the turning section will be described with reference to FIGS. FIG. 9 is a schematic perspective view of the machine room in the upper floor portion of the escalator device. Further, FIG. 10 corresponds to a view in which a main part in the vicinity of the front roller guide rail 20 shown in FIG. 9 is viewed from the C direction. Of the members shown in FIG. 9, members common to those shown in FIG. 8 are given the same reference numerals as those in FIG.
[0066]
As shown in FIG. 9, the pulley 47 is mounted on the shaft of the drive shaft 45 (the bearing 46 of the drive shaft 45 is omitted in FIG. 9) between the pulley 41 b and the speed reducer 43. The pulley 47 is connected via a belt 48 to a pulley 51 that forms part of a mechanism for controlling the moving speed of the front roller. The pulley 51 is of a two-stage type (having a portion for hanging the belt 48 and a portion for hanging the belt 51 below), and the belt 48 is wound around a portion of the pulley 51 that is hidden behind the guide rail 20 for the front roller. It is hung.
[0067]
The pulley 51 is provided at a position in front of the sprocket 40 in the semicircular curved section of the front roller guide rail 20. Further, a plurality of copying pulleys 49,..., 49 are provided along the inside of the semicircular curved section of the front roller guide rail 20.
[0068]
The pulley 51 and the copying pulleys 49,..., 49 are hung by a belt 50 with protrusions provided with protrusions on the outside at regular intervals. In this case, the protruding belt 50 is guided in a curved curve shape by the copying pulley 49 so that the belt circumferential surface of the protruding belt 50 is along the center line of the track of the front roller guide rail 20.
[0069]
As shown in FIG. 10, the protrusion-provided belt 50 is disposed in a space between the inner side surface of the front roller guide rail 20 and the passage region of the front roller 17. On the other hand, the front roller 17 of the pallet is provided with an engagement element 52 that protrudes toward the pallet 9 side. The engagement element 52 is provided coaxially with the front roller 17. The engagement element 52 can be provided, for example, by extending the rotation shaft of the front roller 17. This engagement element 52 is adapted to engage between the protrusions of the protrusion belt 50 in the semicircular curved section of the front roller guide rail 20.
[0070]
The deceleration rate of the pulley transmission system including the pulley 47 and the pulley 51 is set so that the moving speed of the protruding belt 50 is slower than the moving speed of the chain 33.
[0071]
When the motor 44 is driven, the sprocket 40 is rotated and the chain 33 is driven. At the same time, the pulley 51 is also rotated through the pulley 47 and the belt 48, and the pulley 51 rotates the belt 50 with the protrusion.
[0072]
When the pallet 9 passes through the forward path 2 and comes to the turning section from the A direction, first, the front roller 17 moves along the front roller guide rail 20 and eventually reaches the belt 50 with the protrusions. At this time, the rear roller 16 is still in the horizontal section of the rear roller guide rail 19.
[0073]
When the pallet 9 further moves forward, the engaging element 52 of the front roller 17 is engaged between the protrusions of the belt with protrusions 50, and is decelerated to the set speed of the belt with protrusions 50, so that the semicircle of the guide rail 20 for the front rollers Pass through a curved section. Then, since the moving speed of the rear roller 16 is relatively faster than the front roller 17, the rear roller 16 is wound around the sprocket 40 before the front roller 17 and passes through a semicircular curved path. . By this operation, the vertical height position of the rear roller 16 becomes further lower than the vertical height position of the front roller 17, so that the step surface 14 of the pallet 9 is inclined backward. Accordingly, the pallet 9 sinks from the rear side, and the entire pallet 9 is lowered and turned back from the forward path to the return path. The pulley 51 protruding to the pallet moving path side with respect to the front roller guide rail 20 is located in front of the sprocket 40 and therefore does not interfere with the pallet 9.
[0074]
The operation in the reverse direction, that is, the operation of lifting the pallet 9 from the lower return path to the upper outbound path will be described below.
[0075]
When the pallet 9 is moving in the B direction on the return path, which is the lower track, first, the front roller 17 reaches the belt with protrusions 50, and the front roller 17 rises along the curved section of the front roller guide rail 20. . At this time, the rear roller 16 is still in the horizontal portion of the rear roller guide rail 19.
[0076]
When the pallet 9 further advances, the rear roller 16 is wound around the sprocket 40 and starts to rise. In this case, the moving speed of the front roller 17 is maintained slower than the moving speed of the rear roller 16 by the protrusion-provided belt 50, and the rear roller 16 passes through the curved portion before the front roller 17. That is, the front roller 17 and the rear roller 16 move in such a manner that the rear roller 16 catches up with the front roller 17 that has been raised first while passing through the semicircular curved path.
[0077]
After the pallet 9 is inclined so that the rear side is lowered, the pallet 9 rises from the lower return path to the upper outward path, and after the horizontal movement direction is reversed, the tread 14 is restored to the horizontal direction and folded to the forward path. return.
[0078]
In FIG. 9, the front roller guide rail 20 is not provided with the inclination guiding curve portion 25 as shown in FIG. 5, but it is also possible to provide the inclination guiding curve portion 25 as a matter of course.
[0079]
In order to prevent the mechanism from being locked, it is preferable that the protrusions of the belt with protrusions 50 have appropriate flexibility. That is, when the rear roller 16 is too advanced with respect to the front roller 17, it is preferable that the engagement element 52 can get over the protrusion of the belt with protrusion 50. Further, from the same viewpoint, it is preferable that the copying roller 49 can be appropriately elastically displaced with respect to the radial direction of the semicircular curved portion of the front roller guide rail 20.
[0080]
Next, the pallet feeding mechanism on the side without the drive source (the machine room on the lower floor in this example) will be described with reference to FIG. FIG. 11 is a view as seen from the side opposite to the pallet passage side, and FIG. 12 is a view as seen from the pallet passage side. As shown in FIGS. 11 and 12, the rear roller guide rail 19 terminates in front of the driven sprocket 53, and the chain 33 extends from the rear roller guide rail 19 to the driven sprocket 53.
[0081]
A pulley 54a (for belt) is coaxially fixed to the driven sprocket 53 on the side opposite to the pallet passage. Further, the semicircular curved portion of the guide rail 20 for the front roller has the same configuration as that described with reference to FIG. 9 (consisting of a pulley 59, a belt 57 with protrusions, and a plurality of copying pulleys 58). A mechanism for limiting the moving speed is provided. A pulley 54b is coupled to the pulley 59 via a rotating shaft 56 extending in the left-right direction. A belt 55a is wound around the pulley 54a and the pulley 54b. The rotary shaft 56 is disposed on the return path side of the front roller guide rail 20 in the vertical direction above the position through which the front roller 17 passes. The protruding belt 57 shown in FIGS. 11 and 12 is provided only in the lower half of the semicircular curved portion of the front roller guide rail 20, unlike the protruding belt 50 shown in FIG. 9.
[0082]
The chain 33 is circulated and driven by using a motor in the other machine room (for example, the machine room shown in FIG. 9) not shown in FIG. 11 as a drive source, and the driven sprocket 53 is driven and rotated by the chain 33. This rotational force is sequentially transmitted to the pulley 54a, the belt 55, the pulley 54b, and the rotating shaft 56 to rotate the pulley 59 and finally rotate the belt 57 with protrusions.
[0083]
Assuming that the pallet 9 moves in the backward direction from the direction C (see FIG. 11), the engaging element 52 of the front roller 17 of the pallet 9 that has returned from the backward path first reaches the belt 57 with a protrusion. To do. At this time, since the front roller 17 of the pallet 9 has passed through the pallet inclination guiding curve portion 32, the pallet 9 has already moved in a posture inclined backward.
[0084]
When the pallet 9 further moves, the engaging element 52 of the front roller 17 is engaged by the belt 57 with the protrusion. Then, the front roller 17 is moved by the protrusion-provided belt 57 and rises along the semicircular curved portion of the front roller guide rail 20. On the other hand, the rear roller 16 is wound around the driven sprocket 53 and moves up.
[0085]
At this time, the moving speed of the front roller 17 is maintained slower than the moving speed of the rear roller 16 by the action of the belt 57 with protrusions. Therefore, while the posture of the pallet 9 is gradually restored to the horizontal state, the pallet 9 is lifted from the lower return path 3 to the upper forward path 2 and reverses its horizontal movement direction.
[0086]
When the pallet is in the reverse direction, that is, when the pallet comes from the D direction of the forward path (see FIG. 11), the pallet is folded down from the forward path to the return path by the reverse action.
[0087]
The protrusion-provided belt 57 directly applies a movement driving force to the front roller 17 only in the pallet folding section. Therefore, when the pallet 9 is moved from the lower return path 3 to the upper forward path 2, the front roller 17 and the rear roller 16 are moved. Both can be raised to raise the pallet 9.
[0088]
Further, since the belt 57 with protrusions makes the moving speed of the front roller 17 slower than the moving speed of the rear roller 16, the height of the front roller 17 with respect to the rear roller 16 is changed to change the inclination angle of the tread surface. Can be changed between forward / return.
[0089]
As described above, according to the present embodiment, when an escalator device is configured by circulating a pallet for carrying passengers, the space of the folded track portion and the inclined portion of the pallet can be reduced, It is small and the inclined part truss thickness can be made flat. Thereby, it is not necessary to provide a large machine room storage space on the building side, the construction can be simplified and the construction period can be shortened, and the landscape can be improved.
[0090]
[Modification of feed mechanism]
Next, a modified example of the feeding mechanism will be described with reference to FIG. FIG. 13 is a schematic perspective view of a part of the machine room at the end of the truss, as viewed from the opposite direction to the passage side with the pallet.
[0091]
The feed mechanism described in this modification is different from the feed mechanism shown in FIG. 11 in that a torque wire 60 is used to transmit driving force from the driven sprocket 53 to the belt 57 with projections instead of the pulley / belt system. The other structures are substantially the same. In the modification shown in FIG. 13, the same parts as those in the embodiment shown in FIG.
[0092]
As shown in FIG. 13, the torque wire 60 is configured by covering a cord-like body (not shown) capable of transmitting a torsional force with a covering so as to be rotatable and bendable.
[0093]
The driven sprocket 53 is provided with a gear 112 a coaxially, and the gear 112 a rotates in conjunction with the driven sprocket 53. On the other hand, a gear 112b is connected to the tip of a cord-like body (not shown) of the torque wire 60, and the gear 112a and the gear 112b mesh with each other.
[0094]
The other end of the torque wire 60 extends forward and is connected to the feed mechanism drive pulley 59 from the outside of the passage. The pitch circumferential diameter of the feed mechanism drive pulley 59 is smaller than the pitch circumferential diameter of the driven sprocket 53.
[0095]
When the driven sprocket 53 rotates as the pallet 9 moves, torque is transmitted to the other end of the torque wire 60 via the gear 112a, the gear 112b, and a cord-like body (not shown) inside the torque wire 60. This torque then becomes a rotational force to the feed mechanism drive pulley 59 and drives the feed mechanism 58. Since the gear 112b rotates in the opposite direction to the driven sprocket 53, the feed mechanism drive pulley 59 coupled to the tip of the torque wire folded back 180 degrees rotates in the same direction as the driven sprocket 53.
[0096]
According to this modification, the configuration of the feed mechanism can be simplified. Further, since the torque wire is freely bendable, the mounting location can be freely arranged, and the machine room on the side without the drive source can be further reduced.
[0097]
[Safety device on the side of the pallet]
Next, the safety device for the moving passage will be described with reference to FIGS. 14 and 15. 14 is a schematic perspective view of the safety device, FIG. 15 is an enlarged cross-sectional view of the guide rail portion in FIG. 14, and FIG. 15 (a) is a vertical cross-sectional view in the forward sloping section, and FIG. ) Is a vertical sectional view in the horizontal section of the return path. These drawings show the vicinity of the right guide rail portion with respect to the pallet.
[0098]
FIGS. 14 and 15 show an example in which the guide rails in the inclined section are replaced with the front roller guide rails 20 and the rear roller guide rails 19 described above, and are integrated rails 64.
[0099]
As shown in FIG. 14, the integrated rail 64 is provided on a truss on the side of the pallet. A rear roller guide rail portion 63 is formed below the inner rail 64 on the inner side of the cross section, and a front roller guide rail portion 62 is formed on the inner upper side.
[0100]
The roles of these guide rail portions are exactly the same as those of the front roller guide rail 20 and the rear roller guide rail 19 described above. Below the rear roller guide rail portion 63, there is a structural portion of the integrated rail 64 to support the downward load received from the rear roller 16, and above the front roller guide rail portion 62 from the front roller 17. There is a structural portion of the integral rail 64 to support the upward load it receives.
In the pallet 9, a shaft 15 projects in the horizontal direction from the lower end surface of the side surface of the pallet 9. A distance d is provided between the tread surface 14 of the pallet 9 and the upper end of the shaft 15.
[0101]
The side panel 61 extends in the vertical direction between the tread surface 14 and the integrated guide rail 64 along the side surface of the outward path. As shown in FIGS. 15A and 15B, the side panel 61 has a lower end surface that is always above the upper end of the shaft 15 in all the horizontal and inclined sections of the forward path, and the pallet. Nine treads 14 are arranged below the locus drawn.
[0102]
Now, assuming that the pallet 9 is in the horizontal section of the lower floor (in the vicinity of the landing), the side panel 61 extends below the upper surface of the step surface 14 as shown in FIG. Therefore, the front roller guide rail portion 62 and the rear roller guide rail portion 63 are not exposed on the side where the pallet 9 is located.
[0103]
When the pallet 9 further moves and transitions from the horizontal section to the inclined section, as shown in FIG. 15A, the vertical relative distance h2 between the front roller guide rail section 62 and the rear roller guide rail section 63. Is gradually contracted to become h1, and the front roller 17 is supported by the inclined portion that is in the rear side relative to the paper surface of the guide rail portion 62 for the front roller, and the positional relationship between both guide rail portions and both rollers. As a result, the tread surface 14 is moved while maintaining its horizontal posture.
[0104]
In this case, since the side panel 61 and the integrated rail 64 are inclined at the same angle while maintaining a parallel relationship, the upper surface of the step surface is always above the lower end surface of the side panel 61 in each section of each pallet. The integrated rail 61 is not exposed on the side where the pallet is located.
[0105]
In this way, by installing a safety fence-like panel on the side surface of the movement path of the pallet, it is possible to prevent a mechanism portion such as a guide rail from being exposed on the movement path side. Therefore, it can prevent that a passenger and a conveyed product are caught in a mechanism part, and can improve the safety | security of an escalator apparatus.
[0106]
[Pallet step safety mechanism]
Next, a safety mechanism between adjacent pallets will be described with reference to FIGS. In order to realize this safety mechanism, the pallet 71 in which the internal structure of the pallet 9 is changed is used in this example. The other components of the escalator device may be the same. 16 to 18, the description of the front and rear rollers for controlling the attitude of the pallet and the members that support these rollers are omitted for the sake of simplification of the drawings.
[0107]
Inside the pallet 71, a guide groove 65 having a width substantially equal to the lateral width (lateral width) is provided. A shielding curtain 66 is provided in the guide groove 65 so as to be slidable along the guide groove. The guide groove 65 is bent from the horizontal direction to the vertically downward direction behind the pallet 71 and opens to the lower rear side of the pallet 71.
[0108]
A guide roller 72 is rotatably provided inside the bent portion of the guide groove 65. A constant tension spring (constant tension mechanism) 67 is provided inside the guide groove 65 opposite to the opening (the front side of the pallet 71). The constant tension spring 67 is connected to the front end of the shielding curtain 66 and applies a tension that always pulls the shielding curtain 66 forward.
[0109]
On the front side of the pallet 71, a coupler 69 for connecting / disconnecting with a shielding curtain (not shown) of another pallet (not shown) adjacent to the front of the pallet 71 is provided. A slit-like hook groove 68 is provided at the tip of the shielding curtain 66.
[0110]
Details of the coupler 69 shown in FIG. 16 will be described with reference to FIG. Inside the pallet 71, a lever 77 is attached so as to be swingable about a fulcrum 78. Guide rollers 76 and hooks 79 are provided at both ends of the lever 77, respectively.
[0111]
On the other hand, a guide rail 75 is attached to the movement path along the movement locus of the pallet 71, and this guide rail 75 forms a track for the guide roller 76 to roll. For example, the guide rail 75 can be attached to the front roller guide rail 20 along the front roller guide rail 20.
[0112]
The guide rail 75 is provided with smooth undulations in the horizontal direction of the horizontal plane according to the position of the pallet 71. That is, the horizontal distance between the rolling surface of the guide roller 76 of the guide rail 75 and the side surface of the pallet 71 differs depending on the position of the pallet 71. Mainly in the return path section, the distance between the pallet side surface and the rolling surface of the guide roller 76 is relatively large as shown in FIG. 18 (a), and in the forward path section, the distance is as shown in FIG. 18 (b). Is relatively small.
[0113]
A spring 80 is provided on the lever 77 so as to press the guide roller 76 against the guide rail 75.
[0114]
Hereinafter, the operation of the safety mechanism will be described with reference to FIGS. 17 and 18. Now, it is assumed that the escalator device is in ascending operation and the pallet is in the landing section of the lower floor (see FIG. 17 (a)).
[0115]
In this section, the adjacent front pallet 73 (meaning the pallet 71 relatively forward of the two pallets 71 adjacent to each other) and the rear pallet 74 (meaning the pallet relatively behind) are identical to each other. It is in the horizontal plane. In this case, as shown in FIG. 18A, since the side surface of the pallet 71 and the guide rail 75 are separated, the guide roller 76 is pressed against the guide rail 75 by the restoring force of the spring 80 and rolls. At this time, the lever 77 is housed inside the pallet 71, and the hook 79 does not protrude from the front surface of the pallet.
[0116]
When the pallets 73 and 74 move and come to a section where the distance between the side surface of the pallet 71 and the guide rail 75 is narrow, the guide roller 76 is displaced along the guide rail 75 as shown in FIG. As a result, the lever 77 tilts with the fulcrum 78 as the center of oscillation.
[0117]
Then, the hook 79 protrudes from the rear pallet 74 to the outside, and the hook 79 engages with the hook groove 68 of the shielding curtain 66 of the front pallet 73 (see FIG. 17B).
[0118]
Further, when the pallet moves and reaches the inclined section, the front pallet 73 starts to rise, and a step in the height direction with the rear pallet 74 is generated. At this time, the shielding curtain 66 moves along the guide groove 66 and is guided by the guide roller 72 at the curved portion of the guide groove 66 and pulled out from the front pallet 73 (see FIG. 17C).
[0119]
Even if the front pallet 73 rises further relatively, the shielding curtain 66 closes the step portion between the front pallet 73 and the rear pallet 74 (see FIG. 17D).
[0120]
Eventually, when the pallet passes through the inclined section and reaches the upper floor, the step between the front pallet 73 and the rear pallet 74 starts to decrease. Then, the shielding curtain 66 is pulled by the constant tension spring 67 and stored in the pallet (corresponding to FIG. 17C).
[0121]
After that, when the front pallet and the rear pallet are in the same horizontal plane by the reverse operation to the above, the shielding curtain 66 is completely stored inside the step of the front pallet 73 (corresponding to FIG. 17B).
[0122]
Thereafter, the hook 70 of the coupler 69 is housed in the step of the rear pallet 74 to disconnect the shield curtain 66 (corresponding to FIG. 17A), and the front pallet 73 and the rear pallet 74 are separated.
[0123]
According to the safety mechanism described above, the shielding curtain stored in the front pallet in the two adjacent pallets can be connected from the rear pallet, and the step generated between the adjacent pallets from the horizontal part of the forward path to the inclined part. The opening can be shielded. Further, since the shielding curtain is stored without being loosened and the individual pallets can be separated outside the forward path section, the pallets can be circulated individually.
[0124]
The mechanism for interlocking the guide roller and hook in the above configuration may be a gear transmission mechanism using a rack gear and a pinion, for example, or a sliding linear transmission mechanism using a flexible wire.
[0125]
[First Modification of Safety Mechanism for Pallet Steps]
Next, a modification of the shielding film of the safety mechanism described in FIGS. 17 and 18 will be described with reference to FIGS. 19 and 20. FIG. 19 is a schematic side view for explaining this modification, and FIG. 20 is an enlarged view of the front pallet 73 in FIG.
[0126]
The link 81 is long and narrow, and the length of the long side is equal to the width of the tread surface of the pallets 73 and 74. The link 81 is provided with a bearing 83a and a bearing 83b in parallel with its long side.
[0127]
In particular, as shown in FIG. 20C, a roller contact curved surface portion 86, which is a semi-cylindrical curved surface, is formed outside the bearings 83a and 83b. Further, a step is provided on the opposite side of the roller contact curved surface portion 86 of the bearing 83a to form an outer end surface 85 (lower than the back surface of the link 81). On the opposite side of the roller contact curved surface portion 86 of the bearing 83b, a step is provided by cutting and removing the inside of the link 81 to form an inner end face 84.
[0128]
Each of the links 81,..., 81 has a multi-link structure in which each bearing 83a is connected to a bearing 83b of another link by a pin (not shown) so as to be swingable in sequence, as shown in FIG. A multi-link shielding screen 82 is configured.
[0129]
A guide roller 72 is rotatably provided inside the curved track portion of the guide groove 65 of the step 71.
[0130]
The operation of the above configuration will be described below. When the front pallet 73 and the rear pallet 74 are on the same horizontal plane, as shown in FIG. 20A, the multi-link shielding curtain 82 is housed inside the pallet by the tensile force of the constant tension spring 67.
[0131]
As the pallet moves, when the hook 70 of the rear pallet 74 is engaged with the hook groove 68 and a level difference begins to occur between the front pallet 73 and the rear pallet 74, the end link 87 is pulled downward by the hook 70. . Then, the individual links 81,... 81 move along the guide groove 65. In the curved portion of the guide groove 65, the roller contact curved surface portion 86 of each link 81 and the guide roller 72 are in contact with each other, and the link 81 passes through the curved portion of the guide groove 65 with a constant rotation radius.
[0132]
The links 81,..., 81 after passing through the curved portion extend to an angle at which the inner end face 84 of each link interferes with the outer end face 85 of another adjacent link, that is, a relative angle of 0 degrees (no further rotation). , Restrained to a linear shape. Further, since the multi-link shielding curtain 82 is always subjected to a tensile force by the constant tension spring 67, even when an external force from the direction of FIG. 19C is received, the linear shape is maintained without being bent.
[0133]
According to this modification, it is possible to increase the rigidity of the shielding curtain. For example, even if an external force is applied such that the shielding curtain is kicked by a passenger's foot, a situation in which the shielding curtain buckles can be prevented. , Can increase safety.
[0134]
[Second Modification of Safety Mechanism for Pallet Steps]
Next, with reference to FIG. 21, the modification of the coupler of the safety mechanism described in FIG. 17 and FIG. 18 is demonstrated. In this modification, a multi-link mechanism is used for the coupler.
[0135]
As shown in FIG. 21, a link lever 88 is attached to the inside of the pallet 71 so as to be swingable (turnable) via a fulcrum 100a. A guide roller 95 is rotatably provided at the rear end portion of the link lever 88, that is, the end portion on the side close to the lateral side surface of the pallet 71, and can project from the lateral side surface of the pallet 71. A link lever 89 is swingably attached to the front end portion of the link lever 88, that is, the end portion on the side opposite to the guide roller 95 via a rotating shaft 91.
[0136]
Further, a link 90 is swingably attached to the inside of the pallet 71 via a fulcrum 100b. An elongated slit 93 is formed in the link 90. A guide pin 92 provided near the middle of the link lever 89 is slidably engaged with the slit 93.
[0137]
The link lever 89 is bent and extended at the tip of the rotating shaft 91, and the end thereof is connected to the pallet 71 via a spring 98. A hook 94 is formed on the other end side of the link lever 89.
[0138]
In the portion of the rotating shaft 91, the link lever 88 is provided with an arc-shaped slit 97, and a stopper pin 96 fixed to the link lever 89 is engaged with the circular slit 97.
[0139]
On the other hand, a guide rail 99 is attached to the movement path along the movement path of the pallet, and forms a track for the guide roller 95 to roll. The distance between the surface of the guide rail 99 on which the guide roller 95 rolls and the lateral side surface of the pallet 71 changes according to the position of the pallet.
[0140]
Next, the operation will be described. First, in a section where the guide rail 99 is laid so that there is a gap between the lateral side surface of the pallet 71 and the guide rail 99, the link lever 88 receives a tensile force in the left direction in the figure by the spring 98, and the guide roller 95 is It rolls in contact with the guide rail 99 (see FIG. 21A). At this time, the hook 94 is stored inside the pallet 71 and does not protrude.
[0141]
Next, when the pallet moves and reaches a position where the distance between the lateral side surface of the pallet 71 and the guide rail 99 decreases, the link lever 88 turns in the direction of arrow A in FIG. 21B, and the link lever 89 rotates. The hook 94 is inserted into the hook groove 68 of the front pallet by moving in the positive X direction by the parallel link action of the shaft 91 and the link lever 90 (see FIG. 21B).
[0142]
When the pallet further moves and the distance between the lateral side surface of the pallet 71 and the guide rail 99 is further reduced, the link lever 88 turns more greatly. The stopper pin 96 of the link lever 89 limits the relative bending angle between the link lever 88 and the link lever 89 at the end of the circular slit 97 of the link lever 88, so that the two levers 88 and 89 move together. Become.
[0143]
When the pallet 71 further moves and is displaced to a position where the guide roller 95 is pushed into the side surface of the pallet 71, the guide pin 92 slides along the slit 93, and the link lever 88 and the link lever 90 act as a parallel link. The link lever 89 is turned together with the link lever 88 around the fulcrum 100a. Then, the hook 94 is fitted into the hook groove 68 by changing the moving direction from the X positive direction to the Y positive direction.
[0144]
When the distance between the lateral surface of the pallet 71 and the guide rail 99 is increased again, the link lever 89 is pulled in the left direction by the spring 98, and at the same time receives the restoring moment in the clockwise direction of the rotating shaft 91, and reverses the above action. The hook 94 moves in the negative X direction after moving in the negative Y direction. As a result, the link lever 89 is separated from the hook groove 68 of the shielding curtain 66 and stored in the pallet.
[0145]
According to the above modification, the hook can be moved laterally after being inserted into the hook groove to perform a fastening operation, so that the connection between the hook and the shielding film can be made strong and reliable. Further, the accuracy of the connecting position between the shielding curtain and the pallet can be improved.
[0146]
