Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving handrail device of a man conveyor, and more particularly to a moving handrail device of a rack driving type man conveyer for transmitting driving force by providing rack teeth on an inner surface of the moving handrail. .

[0002]

2. Description of the Related Art FIG. 12 shows, for example, JP-A-55-11138.
It is a schematic block diagram which shows the conventional man conveyer similar to what is shown by the gazette of No. 1, the Japanese Utility Model Laid-Open No. 59-192084, etc. In the figure, 1 is a main frame, 2 is a step, 3 is a balustrade installed upright on both sides of the step 2 on the main frame 1, and 4 is a balustrade provided on the balustrade 3 and moving in synchronization with the step 2. .

The step 5 is installed at the upper end of the main frame 1.
Is a handrail drive device that drives the moving handrail 4 and is connected to the drive device 5 via chains 7 and 8. The handrail drive device 6 moves by a drive roller and a pressure roller. The handrail 4 is pressed to frictionally drive the moving handrail 4.

The conventional friction drive type handrail drive device 6 as described above has the following drawbacks. That is, when the man conveyor becomes long-length machine, a slight slip occurs between the moving handrail 4 and the drive roller, so that a speed error is likely to occur.
A shift occurs between the moving handrail 4 and the step 2. Further, since the frictional drive cannot obtain a large driving force, it is necessary to install a plurality of handrail drive devices 6 in a high lift. In addition, the speed of the moving handrail 4 changes subtly due to the influence of rainwater, dust, and the like, and changes in passenger load. Furthermore, a slip occurs due to an abnormal external force applied to the moving handrail 4. Further, since a large pressing force is required by the pressure roller, deterioration or dirt is likely to occur on the surface of the moving handrail 4 (on the side of the decorative rubber).

In contrast to the friction drive type handrail drive device 6 having these drawbacks, as shown in, for example, Japanese Patent Laid-Open No. 4-32491, rack teeth on the handrail side are provided on the inner surface of the moving handrail to drive with gears. A rack-type driving method has also been proposed in which wheels are combined and driven to obtain a large driving force without generating slip.

[0006]

However, in the conventional rack type driving method, since the rack teeth of the moving handrail which can be meshed with the geared driving wheel have one to two teeth, a large driving force should be transmitted. Or when an abnormal external force acts on the moving handrail, a large force acts on the one or two teeth,
There is a problem that the rack teeth may be damaged.
On the other hand, the rack teeth of the moving handrail need to be made of a flexible and stretchable material such as rubber, plastic, or a cloth laminate so that the rack teeth of the moving handrail can be bent, so that the strength can be strengthened. Have difficulty.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a man conveyor which can prevent damage to the rack teeth on the handrail while eliminating the drawbacks of the friction drive type. The purpose is to obtain a moving handrail device.

Embodiments of the present invention will be described below with reference to the drawings. Example 1. 1 is a schematic configuration diagram showing a passenger conveyor having a moving handrail device according to an embodiment of the invention of claim 1, FIG. 2 is an enlarged view of a main part of FIG. 1, and the same or corresponding parts to FIG. 12 are the same. The reference numerals are given and the description thereof is omitted.

In the figure, reference numeral 11 denotes a moving handrail which is provided on the balustrade 3 and moves in synchronization with step 2. The inner surface of the moving handrail 11 has a large number of handrail side rack teeth 11a as shown in FIG. Are continuously formed over the entire circumference. Reference numerals 12 and 13 are a drive wheel and a driven wheel as a pair of belt wheels provided on the way of the return path of the moving handrail 11. The drive wheel 12 is connected to the drive machine 5 of step 2 via chains 14 and 15. Has been done. Reference numeral 16 denotes an endless belt wound around the drive wheel 12 and the driven wheel 13, and the handrail side rack teeth 11a are provided on the outer surface of the belt 16.
Belt-side rack teeth 16a meshing with each other are continuously formed over the entire circumference.

With the above-described structure, the drive wheels 12 are connected to the chain 1 from the upper sprocket 5a of the drive machine 5.
The driving force is transmitted through 4, 15. This drive wheel 12
The rotation of the belt causes the belt 16 to circulate and the driven wheel 1
3 rotates, and the moving handrail 11 is sent and moves.

In such a moving handrail device, the drive wheels 12 are
Since a large number of belt-side rack teeth 16a positioned between the shaft of No. 1 and the shaft of the driven wheel 13 simultaneously mesh with the handrail-side rack teeth 11a, the load applied to one handrail-side rack tooth 11a is significantly reduced. Therefore, the handrail side rack teeth 11a are prevented from being damaged, and the reliability is improved. For example, if the minimum number of meshing teeth is 1 in the conventional method (Japanese Patent Laid-Open No. 4-32491), the number of meshing is 5 in the first embodiment.
It is possible to set 10 to 10, and the load acting on one handrail side rack tooth 11a can be set to 1/5 to 1/10.

Is pressed against the first sprocket 21,
Both of them rotate together with no slippage and power is transmitted. Therefore, the speeds of step 2 and the moving handrail 11 can be made to be the same as in the above-described first and second embodiments, and even if the man conveyer becomes a long machine length, the step 2 and the moving handrail 11 are changed due to load fluctuations. There is no deviation.

However, when a torque equal to or greater than the set torque value is generated (when an abnormal external force is generated), slippage occurs between the first sprocket 21 and the second sprocket 22 and an abnormal external force is generated. Transmission is blocked. That is, in the rack-driven mobile handrail device, if the mobile handrail 11 is locked for some reason, the chains 14, 15
Although there is a risk that other devices will be destroyed, such an accident can be prevented by inserting the slip clutch 27 into the drive system.
