Abstract

PROBLEM TO BE SOLVED: To provide a safe and efficient moving walk by installing a plurality of carrier rollers so to be freely rotated, driving the sprockets of the carrier rollers with a chain and respectively arranging the carrier rollers of slow circumferential speeds in the vicinity of a getting on and off site and the carrier rollers of fast circumferential speeds in middle parts. SOLUTION: A plurality of carrier sprockets 30 are provided between a carrier roller driving sprocket 13 and a follower sprocket 14 rotated by a driving device 10 and a carrier chain 15 is wound and hung on these sprockets. Among these carrier sprockets 30, a low speed sprocket 31 is rotatably arranged in a part opposed to each of floor plates 2 and 3 where passengers get on and off and set to a large diameter. A plurality of accelerating/decelerating sprockets 32a to 32c are arranged side by side and these are set to small diameters in sequence. Further, a minimum diameter high speed sprocket 33 is arranged in the middle part of a moving sidewalk so as to be freely rotated. Thus, an object to be carried is carried at a low speed in the vicinity of the platform and at a high speed in the middle part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a moving walkway which can safely and quickly carry passengers or objects to be transported even in a relatively long journey.

[0002]

2. Description of the Related Art In the case of a moving sidewalk installed at a place such as an airport, the speed is too slow for a normal moving sidewalk operated at a speed of about 40 m / min, and it takes time to move passengers and transported objects. There was a problem that took too much.

[0003]

For this reason, various moving walkways with a special structure have been proposed, which move slowly when passengers get on and off, and move at high speed in the middle, but all of them have an extremely complicated mechanism. It is a device. For example, a variable-speed moving walkway in which a boarding / alighting section is curved to change a speed vector in the traveling direction corresponds to the most typical example.

The present invention has been made in view of the above points, and an object thereof is to provide a variable speed moving walkway having a simple structure and mechanism.

[0005]

SUMMARY OF THE INVENTION According to the present invention, in a moving walkway provided with a plurality of conveying rollers rotatable in the traveling direction, the conveying rollers are provided with coaxial sprockets.
The sprocket is driven by a chain, and the conveying rollers having a low peripheral speed are arranged near the entrance / exit, and the conveying rollers having a high peripheral speed are arranged at an intermediate portion.

[0006]

With the above-described structure, the object to be conveyed is gently conveyed near the entrance / exit and at high speed in the middle portion.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall view showing an embodiment of the present invention, in which 10 is a drive device for a moving walkway installed in a machine room 1, and 11 is a gear 10a fixed to the shaft of the drive device 10 and a shaft 12a. It is a drive chain that is wound around the sprockets 12 that are formed to transmit power.

Reference numeral 13 designates a conveying roller driving sprocket fixed to a shaft 12a, and a conveying chain 15 in which a plurality of conveying sprocket groups 30 described later are meshed is wound between the driven sprocket 14 on the opposite side. .

Reference numeral 31 denotes a low-speed range sprocket that is responsible for the low-speed range of the above-mentioned transport sprocket group 30, and is rotatably provided at a portion facing the floor plates 2 and 3 on which passengers get in and out. The low speed range sprocket 31 has the largest diameter in the transport sprocket group 30.

Reference numerals 32a, 32b, and 32c denote acceleration / deceleration area sprockets which are responsible for the acceleration area or deceleration area of the transport sprocket group 30, and the diameters of which decrease in the order of 32a, 32b, and 32c.

A high-speed sprocket 33, which is responsible for the high-speed region of the transport sprocket group 30, is rotatably arranged in the middle of a moving walkway and has the smallest diameter in the transport sprocket group 30.

Reference numeral 41 is a conveying roller that is coaxially rotatable with the low speed sprocket 31, and 42 is a conveying roller that is coaxially rotatable with the acceleration / deceleration area sprockets 32a, 32b, 32c.

Numeral 43 is a conveying roller provided coaxially with the high speed sprocket 33 so as to be rotatable.
1, 42 and 43 all use rollers having the same diameter.

Reference numeral 50 is a sprocket for preventing the transport chain 15 from hanging down on the way.

With such a structure, the drive device 10 drives the drive chain 11, the sprocket 12, and the shaft 12.
a, the circulation chain 15 is circulated at a constant speed through the conveyance roller driving sprocket 13, and the low speed sprocket 31 and the acceleration / deceleration regions sprocket 32a, 32b, 3
2c and the high-speed range sprocket 33 rotate at angular velocities corresponding to their diameters, so that the transport roller 41 coaxial with the sprocket 33 is slow, the transport roller 43 is fast, and the transport roller 42 is at an intermediate velocity. As a result, passengers and the like are transported by the transport rollers 41 to 43 gently in the vicinity of the entrance / exit, gradually or gradually in the acceleration / deceleration region, or gradually and most quickly in the high-speed region. .

In such an embodiment, as a matter of course, the transport rollers 41 to 4 depending on the size of the transported object.
It is necessary to determine the size of the diameter of No. 3, and it is important to use a roller having a diameter smaller than the size of the passenger's foot when transporting personnel.

In this embodiment, an example has been described in which the diameter of the sprocket meshed with the transport chain 15 is changed to change the rotation speed of the transport rollers 41 to 43. However, the diameters of the sprockets are all the same and the transport rollers are the same. It is also possible to increase the diameters of 41 to 43, for example, in the order of the transport rollers 41, 42, 43 to change the peripheral speed of the transport rollers.

Next, another embodiment of the present invention will be described with reference to the drawings. FIG. 2 is an overall view showing another embodiment of the present invention, in which the same reference numerals as those in FIG. 1 denote the same components.

Numeral 31 'is a low-speed sprocket arranged at the front end and one at the rear end, respectively.
It is the largest sprocket in 0 '.

Numeral 33 'is a high speed sprocket arranged at the front end and one at the rear end, respectively.
It is the smallest sprocket in 0 '.

Reference numeral 41 'is a conveying roller provided coaxially with the low speed sprocket 31' so as to be rotatable. A well-known conveying belt 61 is endlessly wound around the front and rear conveying rollers 41 ', 41'. Has been.

Reference numeral 43 'is a conveying roller provided coaxially with the high speed sprocket 33' so as to be rotatable. The well-known conveying belt 63 is endlessly wound around the front and rear conveying rollers 43 ', 43'. Has been.

Even with such a structure, the drive unit 10
Drive chain 11, sprocket 12, shaft 1
2a, only by circulating the transport chain 15 at a constant speed through the transport roller driving sprocket 13, the low-speed sprocket 31 'and the high-speed sprocket 33' rotate at angular velocities corresponding to their diameters. The transport roller 41 'rotates relatively slowly, while the transport roller 43' rotates rapidly, so that the transport belt 61 circulates at a slow speed and the transport belt 63 circulates very fast, resulting in the passenger These are transported slowly near the entrance / exit and very fast in the middle.

Also in this embodiment, the diameters of the sprockets are all the same, and the diameters of the conveying rollers 41 'and 43' are changed to change the circulating speed of the conveying belts 61 and 63. Is also possible.

[0025]

As described above, according to the present invention, the object to be conveyed is conveyed very gently at the entrance / exit, while it is conveyed at a high speed in the middle portion, so that it is extremely safe and efficient. You can get a moving walkway.
