Abstract

PURPOSE:To enable infants and users handicapped with their feet to easily get on/off a footboard regardless of weather by relaxing moving speed for users getting on/off a space between an entrance and the footboard by an auxilairy conveyor which is reduced in speed with respect to the speed of a footboard adjacent to the end section of the footboard. CONSTITUTION:When each user who has boarded on a footboard 6, gets off out of the footboard 6 of an upper section at the exit of an upper story via auxiliary conveyor 1, since the relative speed of the moving speed of the footboard 6 against the moving speed of the auxiliary conveyor 1 is reduced by means of the belt 2 of the auxiliary conveyor 1 which is driven for example, at a half speed against the moving speed of 30m/sec of the footboard 6, impact applied to the feet of each user can thereby be relaxed when he moves to the auxiliary conveyor 1. Similarly, impact applied to the feet can be relaxed when he moves to the auxiliary conveyor 1 from the footboard 6 at the exit on the lower story side of a truss. By this constitution, even infants and users handicapped with their feet can easily get on/off regardless of weather.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a man conveyor such as an escalator.

[0002]

2. Description of the Related Art In escalators, the speed and inclination angle of steps have been regulated by law, and the speed of steps of most escalators currently in operation is
At 30 m / min, the tilt angle is 30 degrees. For escalators installed in a small part of public facilities, the speed of steps is 25m / min.
And, there are some with a tilt angle of 25 degrees, but it is rare.

On the other hand, with the spread of escalator,
At public facilities and urban terminal stations, escalator with steps for wheelchairs has been installed that has been developed so that wheelchair users can easily get on and off.

In this wheelchair-equipped escalator, the staff operates the key switch provided at the entrance / exit of the escalator to switch the escalator in the normal operation mode to the wheelchair operation mode, so that the wheelchair step can be moved to the entrance / exit. When approaching, the speed of the step is decelerated or further stopped, and the upper surface of a particular step, for example, two steps at the entrance / exit, becomes the same height. Of these, the step on the upper floor adjacent to the step on the upper floor is , The upper surface is slanted so that the wheelchair can be mounted. The escalator with steps for wheelchairs is on the rise due to the demands of the times and the transition to an aging society in the future.

[0005]

However, in the escalator configured and operated as described above, when the vehicle is in a normal driving state, for example, when an infant or a user with a disability gets in the vehicle, it is difficult to get in and stop. As a result, the users who follow behind may sometimes stand in a line. Then, if there is a rush, the flow of the user will be stagnant and the transport efficiency will be reduced.

Further, when getting off the escalator, especially on a rainy day or a snowy day, if the upper surface of the boarding / alighting plate on the exit side is wet with rainwater or snow dripped from the user's rain gear, etc. The sudden stop of the inertia of the passengers who got off at the speed of min may not only cause their feet to slip on the upper surface of the boarding / alighting board, but also cause them to fall.

On the other hand, in the escalator with steps for wheelchair,
A staff member transfers the wheelchair from the boarding / alighting board to the wheelchair steps,
In particular, when transferring to a step in a decelerated state, the transfer work is laborious because the timing must not be missed.

Further, even in an escalator which is designed to stop when getting in and out of a wheelchair, when transferring from the wheelchair steps to the board at the exit side, the board is higher than the wheelchair steps. As for the staff, transferring the wheelchair requires labor. This becomes a particular problem in a heavy-weight wheelchair that is driven by an electric motor with a battery increasing in recent years.

Therefore, the object of the invention described in claims 1 and 2 is to easily and safely, regardless of the weather such as snowfall or rainfall, and also for infants, the elderly, and users with disabilities. An object of the present invention is to obtain a man conveyor that allows a wheelchair user to get on and off more easily.

And the speed reducer 4 are also provided inside a truss on the lower floor side (not shown), and the input shaft of the speed reducer 4 on the lower floor side is connected to the shaft of the step chain sprocket provided at the end on the lower floor side. Has been done. The speed reduction ratio of the speed reducer 4 is set so that the speed of the belt 2 is half the speed of the step chain, that is, 15 m / min.

A safety switch 5 whose details are shown in FIG. 3 is provided below the center of the auxiliary conveyor 1. In FIG. 3, a speed detection unit box 20 which is a component of the safety switch 5 is attached to the lower part of the auxiliary conveyor 1. A speed detector 17 is housed inside the speed detection unit box 20, and a pair of contacts 18 provided with wipe springs on the upper part of the speed detector 17 are arranged in a lower part of the speed detector 17 with their contact surfaces facing downward. It is stored.

A pin 15b is provided on the left side of the contact 18 in a direction orthogonal to the plane of the drawing, and an intermediate portion of a lever 15a is swingably supported by the pin 15b. A copper plate is fixed to the upper surface of the right end of the lever 15a, and a bearing (not shown) is inserted into the left end of the lever 15a. A roller 15 whose outer periphery is made of urethane rubber is inserted into the bearing through a shaft 15c. It is rotatably attached.

A rotating shaft of a pulse transmitter (not shown) is connected to the shaft 15c, and a signal line of the pulse transmitter is connected to a speed detector through a connector 19 provided on the upper left side of the speed detecting unit box 20. Connected to 17 inputs.

The speed detector 17 is connected to each terminal of a contactor 18 provided on the upper right end of the lever 15a. The output signal line of the speed detector 17 is the speed detection unit box.
It is connected to the emergency stop circuit of the control section of the escalator provided inside the truss via the connector 19B provided on the upper right side of the upper part of 20.

The lower end of the tension spring 16 is locked to the lower end of the speed detecting unit box 20, and the upper end of the tension spring 16 is locked to the lower surface of the right end of the lever 15a under tension. Therefore, the roller 15 is pressed against the lower surface of the belt 2 of the auxiliary conveyor 1 by the restoring force of the tension spring 16 shown by the arrow D, as shown by the arrow E.

The safety switch 5 shown in FIG. 3 is similarly attached to the lower portion of the auxiliary conveyor provided on the lower floor side of the truss, and the signal line of the speed detector is connected to the emergency stop circuit of the escalator. .

In the escalator constructed as described above, in FIGS. 1 and 2, the passengers on the steps 6 pass through the auxiliary conveyor 1 from the steps 6 at the upper left end of FIG. 1 at the exit on the upper floor side. When descending, the relative speed of the step moving speed to the moving speed of the auxiliary conveyor 1 is reduced by the belt 2 of the auxiliary conveyor 1 driven at a speed of half the moving speed of the step 6 of 30 m / min. Therefore, it is possible to reduce the impact that the foot receives when moving to the auxiliary conveyor 1.

Similarly, at the exit on the lower floor of the truss, it is possible to mitigate the impact on the foot when moving from the steps 6 to the auxiliary conveyor 1 from the steps 6, so that, for example, in the case of rain or snow. In addition, even if the upper surface of the belt 2 is wet with rainwater or snow that has fallen from the passenger's coat or rain gear, it is possible to eliminate the risk of slipping due to a sudden stop as in the past, and for people with disabilities. It is possible to eliminate the anxiety of old people.

This is the same when getting on the escalator as shown by the arrow B in FIG. 2. The speed difference of 30 m / min of the conventional escalator becomes a relative speed of 15 m / min. Since it is possible to prevent hesitation during boarding for passengers who are inconvenient, it is possible to prevent the stagnant flow of passengers during rush hours as described in the related art.

Further, in the event that the foot of a passenger who transfers from the step 6 to the auxiliary conveyor 1 touches the tip of the auxiliary conveyor 1 and the tip of the auxiliary conveyor 1 is lifted, it is shown in FIG. Roller 15 provided on the safety switch 5
Moves up and the lever 15a swings clockwise about the pin 15b. Then, the contact of the contact 18 is separated,
The escalator emergency stop circuit to which this contact signal is connected operates, and the operation of the escalator is stopped.

In the above embodiment, the escalator is
In the general escalator, it was explained in the case where the wheelchair steps are not provided, but the same can be applied to the wheelchair step escalator, and the rear wheel of the wheelchair is driven by an auxiliary conveyor, By driving the wheelchair in the direction of the steps, transfer to the wheelchair steps is further facilitated.

Further, in the above embodiment, the ratio of the speed of the steps to the auxiliary conveyor is set to 2: 1. However, the ratio may be changed to, for example, 3: 1 at the entrance and at the exit. For example, it may be 3 to 2. Depending on the place where the escalator is installed, the ratio may be determined for each user corresponding to the user group and different depending on the place and time.

That is, the ratio of the speed of the steps to the speed of the auxiliary conveyor is the same both on the upper floor side and the lower floor side, and when operating on the upper floor side and the lower floor side. On the entrance side, increase the speed ratio to 3: 1 to prevent hesitation when getting in, and on the exit side decrease the speed ratio to, for example, 3 to 2 to prevent user stagnation on the auxiliary conveyor, You may make the flow smooth.

Further, in the above-mentioned embodiment, the drive source of the auxiliary conveyor is explained as an example in which it is connected to the drive source for driving the steps through the speed reducer 4 in the upper layer, but both the upper layer and the lower layer are auxiliary conveyors. A dedicated electric motor may be provided, and a speed reducer may be connected to the electric motor to provide the invention according to claim 2.

In this case, electric motors for driving the auxiliary conveyors are provided on the upper floor side and the lower floor side, respectively, and each electric motor is started by a signal from the control unit of the escalator, which is a three-phase induction motor for driving the escalator. By providing a control unit that individually controls the speed of each electric motor in response to the speed of the escalator, the ratio with the speed of the steps described above can be set independently for the upper floor side and the lower floor side. Since it can be controlled, there is an advantage that it is possible to perform an easier operation for getting on and off according to the difference in users at the installation location.

Further, even when an abnormality occurs in the auxiliary conveyor, it is possible to stop only the auxiliary conveyor and continue the operation as a normal escalator or an escalator with a wheelchair step. Furthermore, during maintenance and inspection,
It is also possible to operate only the auxiliary conveyor.

Furthermore, in the case where the invention is applied to the escalator with steps for wheelchairs by using the drive source of the auxiliary conveyor as a dedicated drive source and individually controlling it by the control unit, the wheelchair is used. The labor of the staff when transferring from the landing gate to the wheelchair steps through the auxiliary conveyor is reduced.

That is, when transferring the wheelchair to the auxiliary conveyor, the operation of the auxiliary conveyor is temporarily stopped. When you move the wheelchair to the auxiliary conveyor and the wheelchair steps approach, depending on the wheelchair operation mode entered earlier, for example, the auxiliary conveyor accelerates to 8 m / min for the steps decelerated to 5 m / min. As a result, the transfer to the wheelchair steps can be facilitated, and the passenger's discomfort due to the change in speed during the transfer can be eliminated.

When the transfer to the wheelchair steps is completed, it is accelerated to the speed of 30 m / min during normal operation by the operation of the boarding confirmation switch by the attendant, similar to the conventional wheelchair step escalator. . When the steps of the escalator are accelerated to a speed of 30 m / min in normal operation,
The auxiliary conveyor on the entrance side will return to the speed of 15m / min first in order to accommodate the boarding of ordinary passengers.

On the other hand, on the exit side, on the contrary to the entrance side, the wheelchair steps approach the boarding plate, for example, 8 m / min.
When the wheelchair is decelerated, the wheelchair is transferred to the auxiliary conveyor controlled at a speed of 10 m / min, and when the staff operates the descend confirmation switch, the auxiliary conveyor on the exit side is gradually decelerated. Stop.

When the wheelchair is transferred from the auxiliary conveyor to the boarding / alighting board by the staff, the wheelchair operation completion switch is operated by the staff so that the auxiliary conveyor on the exit side returns to the speed of 15 m / min and becomes the normal operation state. Become.

Therefore, in the escalator thus constructed, when the wheelchair is transferred from the boarding / alighting board to the wheelchair steps through the auxiliary conveyor, the rear wheels of the wheelchair are operated at a speed of 8 m / min. The wheelchair moves toward the wheelchair steps because it is rotated by the belt. Therefore, the clerk can easily transfer the wheelchair to the wheelchair steps, and even a heavy wheelchair traveling by an electric motor can be easily and smoothly transferred.

Although the above embodiment has been described as applied to an escalator, it can be applied to a passenger conveyor including a moving sidewalk in the same manner. Further, in the above-described embodiment, the auxiliary conveyor 1 is described as an example in which it is provided from the middle portion to the tip of the boarding / alighting board 21 as shown in FIGS. 1 and 2, but it may be provided over the entire length of the boarding / alighting board 21. .

Further, the driving roller 3A is provided with sprockets at both ends thereof, the reduction gear is also provided with a pair of sprockets, and a chain is wound around each of the sprockets to prevent the roller 3A from being twisted with respect to the driving torque. But it is okay. Furthermore, a tension roller may be provided in the lower center of the auxiliary conveyor, and the tension of the belt 2 may be made constant by passing the lower portion of the belt 2 through the lower surface of the tension roller.
