Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a passenger conveyor, and particularly to a passenger conveyor in which a specific step must be stopped at an entrance.

[Background of the invention]

Conventional passenger conveyors were intended for continuous mass transportation and operated continuously at a constant speed, but they were difficult for the elderly and physically disabled to use. However, in recent years, there has been a demand for passenger conveyors that can be used by people with physical disabilities and wheelchair users, and for this reason, attempts have been made to incorporate special steps into passenger conveyors that are designed to carry disabled people and wheelchair users.

Therefore, when disabled people use the passenger conveyor, they must be able to use these special steps.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a passenger conveyor with dedicated operation using special steps for the disabled.

[Summary of the invention]

In the present invention, a special step for use by a disabled person is temporarily stopped at the entrance, and after the disabled person or the wheelchair gets on board, the dedicated low-speed operation is carried to the exit and then stopped.

[Embodiments of the invention]

An embodiment of the present invention will be explained with reference to FIGS. 1 and 2.

Electrical equipment 1 is a dedicated step for transporting disabled persons or wheelchairs.

A plate 2 made of metal, plastic, etc. is attached to the bottom of the step so as to protrude. A magnetically operated switch 3 that engages with this plate is provided near the entrance of the passenger conveyor. In other words, the contacts of this switch are always closed due to the magnetism of the built-in permanent magnet, but when a plate attached to the step gets caught between the switch's magnet and the contacts and cuts off the magnetism, the contacts open. . Therefore, when the dedicated step 1 comes to the position of the switch 3 and the plate 1 and the switch 3 are engaged, the contacts of the switch 3 are opened, so that the position of the dedicated step can be detected and dedicated operation can be performed. Fig. 3 shows a passenger conveyor of the present invention incorporating a dedicated step and a dedicated operation switch, and on the lower floor there is a magnetically operated switch BR for commanding deceleration during ascending operation and a magnetically operated switch BR for commanding stop on the lower floor. Switch SRI is installed. Also, 1. On the upper floor there is a magnetically operated switch UR for deceleration command during descending operation.
A magnetically operated switch SR2 for commanding the upper floor to stop is installed. This passenger conveyor normally operates at a constant speed, but when performing special operations, it operates at a low speed in order to ensure that the dedicated steps stop correctly at the entrance. For this reason, 1. For example, as shown in FIG.
'M and a motor LM for low speed operation are provided, contact HH1 is closed during normal upward operation, contact HH2 is closed during downward operation, contact LLI is closed during upward operation during dedicated operation, and contact LLI is closed during downward operation. LL2 is closed.

Next, the dedicated operation control method of the present invention will be explained with reference to FIGS. 5 and 6. During normal operation, when the switch is set to 1 in the upward direction (relay CD side), the relay H1 is energized and self-holding, the electrode contactor HHI is energized, and the motor HM is operated in the upward direction. Next, when a dedicated operation in the upward direction is required, switch 2 is turned on to the relay CD side in the normal upward operation state, and the relay CU is energized and self-holding. (At this time, even if 2 is inserted into the relay CD side, relay H1 is ONL and relay H2 is 0FFL/, so relay CF is not energized).

In this state, the special step first passes through the magnetically operated switches SR2 and UR installed inside the passenger conveyor, and the switch is set to 0FFL, but nothing changes.

Next, when the dedicated step comes to the magnetically operated switch BR on the lower floor and the switch BR is turned OFF by the shielding plate of the dedicated step, the relay BS is turned ON by the circuit shown in Figure 6, so the motor HM is operated. Auxiliary relay H1 for
At the same time, the auxiliary relay Ll and the electromagnetic contactor LL1 are sequentially turned on, and the motor LM causes the passenger conveyor to operate at low speed. Next, when the shielding plate of the special staircase and the switch SRI are engaged and the SRI is turned off, the relay 81 is turned on in the circuit shown in Fig. 6, so the auxiliary relay L1 is set to 0FFL,
The electromagnetic contactor LLI turns OFF and the man conveyor stops. As a result, the special stairs will stop at the entrance on the lower floor, so please place the disabled person or wheelchair on the special stairs and press the switch.
When it is turned to the rising side, the relay P1 becomes ONL and self-holds, the relay L1 becomes ONL and the electromagnetic contactor LLI turns ON, the motor LM rotates, and the step rises at a low speed.

At this time, even if you turn the switch 3 to the descending side or turn the switch 1, the relay CU is ONL, so you cannot operate. When the special staircase comes near the exit on the upper floor, the shielding plate of the special staircase engages with switch SR2, and SR2 turns OFF.
Then, relay S2 is ONL, Ll is OFF, LLI
is turned off and motor LM stops. At this time, relay C
Since U is turned OFF, relay P1 is OFFFL, and relay S2 is also QFF, the exclusive operation circuit for the passenger conveyor is released. Therefore, after the disabled person or wheelchair gets off the vehicle, normal operation is possible by immediately setting the switch to 1. In addition, when dedicated operation in the downward direction is required, first
Set switch 1 to normal operation in the downward direction, then set switch 2 to the relay CD side to turn relay C'D on and off.
The private steps will then stop at the entrance to the upper floor in the same order as described above. Next, when the switch 3 is set to the descending side, the passenger conveyor will run downward at low speed, and when the shielding plate of the special step and the switch SRI on the lower floor engage, it will stop at the exit of the lower floor. This operation is performed in the same manner as this upward operation. In the above explanation, an example was shown in which the low-speed motor LM is used for low-speed operation, but the speed conversion method is a method in which the power frequency is converted using one AC motor (switches BR and UR attached to the conveyor body and a dedicated step Any known method may be used, such as a method in which the shielding plates of 1 and 2 engage with each other and a deceleration command is issued, thereby performing frequency conversion control, or a method in which a DC motor is used to control current and voltage.

〔Effect of the invention〕

According to the present invention, it is possible to reliably stop the dedicated step at the entrance, it is possible to drive safely at low speed, it is possible to drive with a pre-selected directional ratio, and even after the dedicated step has been operated from the entrance to the exit. can automatically return to a state in which normal operation is possible.
