Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a wheelchair combined escalator for transporting a disabled person with a wheelchair.

[0002]

2. Description of the Related Art A conventional escalator will be described with reference to FIGS.

[0003] In a normal step device of an escalator, since the depth dimension of each step is short, it is not possible to carry a disabled person's wheelchair mounted on one step of the step with the disabled person in a horizontal posture.

[0004] For this reason, in order to enable a disabled person in a wheelchair to be transported by the escalator 1 as it is, a part of a step row composed of a large number of steps 2, 2, ... connected endlessly has a tread height. Incorporate three steps of special steps 3 with a mechanism that can be changed, and during wheelchair transport operation,
Adjust the three steps so that the treads of the two steps are at the same height and the other is tilted and held so that the wheelchair can be mounted with a deep wheelchair mounting space. There is an escalator 1 for wheelchairs.

[0005] In such an escalator equipped with a stepping device, the speed of the escalator is automatically controlled when getting in and out of the vehicle so that the wheelchair can be used safely, so that the escalator can be decelerated or put in the wheelchair. When the operation is completed, an operation control system that accelerates to improve the operation efficiency is adopted.

[0006] This is, when switching the escalator typically are driving the wheelchair operation mode by the switch, several detection switch L1~L6 provided in the circulation path, detects a specialized step 3, control of the escalator A signal of deceleration, acceleration or stop is sent to the control device.

[0007]

BRIEF Problem to be Solved] In the conventional wheelchair also serves escalator of such mechanisms, escalator or the step detection switch L1~L6 provided in the circulation path is working properly, or the like or not the disconnection Is switched to the wheelchair driving mode, driving is tried, and it is confirmed that the vehicle operates normally, and then the method of mounting the wheelchair is used.

According to such a method, if there is a failure in the escalator, the failure will be known after driving, and it will be troublesome to process the trouble and trouble the escalator user.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem. An object of the present invention is to make it possible to confirm in advance whether or not a detection switch is abnormal without switching to a wheelchair driving mode and driving. It is to provide a reliable escalator.

[0010]

SUMMARY OF THE INVENTION The present invention relates to a method for controlling
Special features that can be changed to wheelchair-mounted steps by rearranging
A special step is provided, and a detection switch for detecting the passage of the special step is provided.
The pitch, the speed control in the wheelchair luck rolling mode
In the control device for the wheelchair / escalator, the detection switch
Detection of passing special steps by the switch during normal operation.
Always, and output the signal from the detection switch
By sending it to the change control system check program.
Provision of means for checking for switch errors
It is characterized by.

[0011]

[Function] Since the detection switch always operates during normal operation and keeps sending signals to the system check program, abnormalities in signals and switch systems can be detected during normal operation, and malfunctions when the wheelchair is mounted Can be eliminated. In addition, it is not necessary to check the detection switch by entering the truss during maintenance.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments shown in FIGS.

[0013] Special (side rear wheels of the step ascent) rear wheel of the step 3 mounting the cam 5 of the detection switch-actuating the fourth fixed shaft, a plurality of detection switches (limit switch) provided in the footstep circulation path L1 ,... L6 are activated once while the special step 3 makes one cycle, and this signal is transmitted to the wheelchair operation control system check program of the control device.

[0014] With such a configuration, when the wheelchair mode operation of the escalator also, during normal operation also specialized step 3 will be that actuates the switch L1, ... L6 detect at all times.

[0015] For example when the wheelchair operation mode, the detection switch L1, ... L6 is gradually sent sequentially, optionally transmits a signal or to accelerate or decelerate or stop the escalator to the speed control unit of the escalator.

[0016] However, the program for the system check is in order of output from the switch detect at the same flow at the time of wheelchair operation
Based on the received signal, the acceleration / deceleration signal is sent to a monitoring panel where it can be visually checked whether the signal is output in a normal flow.

[0017] shown by the circuit diagram of an example of a prior dangerous detecting switch system check program (Figure 3). This program (circuit diagram) is a program that starts during normal operation of the escalator, and operates assuming that the mode has been switched to the wheelchair operation mode.

In the configuration of the circuit diagram (program), the operation of the detection switch L1 which is turned ON first on the circuit diagram is set to X001, and the self-holding circuit is set by the internal contact R001. This self-holding circuit returns with the internal contact R003.

Similarly, the operation of the detection switch L2 which is turned on secondly is set to X002, and the self-holding circuit is set by the internal contact R002. In the same manner, the operation of each detection switch is held by itself, for example, when the detection switch L2 is turned on, and then the detection switch L3 is turned on.
If but detected switch L4 is ON without being ON, the program will perceive an abnormality of the L3 switch, and sends it to the monitoring equipment (lighting, such as pilot lights). Furthermore, the internal contact R0
By making the 01 or internal contact Y001 send a signal directly to the monitoring panel, you can immediately check which detection switch has failed.

[0020]

According to the present invention, the output signal of the detection switch specialized step is taken even during normal operation, the detection switch
Switch is checked for abnormalities, so
An abnormality in the switch system can be found during normal operation, and a malfunction that would occur when the vehicle is mounted on a wheelchair can be prevented beforehand, thereby improving the reliability of escalator operation.
