Abstract

PROBLEM TO BE SOLVED: To prevent a passenger conveyor from being stopped on the way by arranging a passenger detecting device in a space not less than at least the width of a landing, and composing a multibeam sensor of a light projecting part and a light receiving part extended in a horizontal direction. SOLUTION: When a passenger intercepts beams 9 at a landing port 4, a contact is closed. When an automatic operation changeover switch is closed, a relay is excited to close the contact, so that a conductive circuit is formed to excite a timer relay. While the passenger intercepts the beams 9, the closed state of the contact continues, and this state continues until the passenger gets on a footstep 3. When the passenger gets on the footstep 3 to terminate interception of the beams 9, the timer relay starts counting and stops in about ten seconds after the passenger gets off from a descending port 5. Since counting of the timer relay is not started while the passenger is at the landing port 4, even in case an old person or the like stays at the landing port 4 after the start of a passenger conveyor and then gets on the footstep 3, the old person can be positively transferred up to the descending port 5.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor operating device for transferring passengers horizontally or vertically.

[0002]

2. Description of the Related Art Conventionally, a passenger conveyor (escalator) of an automatic driving system is, as shown in Japanese Patent Publication No. 60-23074 and Japanese Patent Laid-Open Publication No. 1-156296, a passenger comprising a photoelectric switch provided at the entrance. When a passenger is detected by the detection device, the escalator starts operating, and thereafter, for example, after two minutes, the operation is automatically stopped.

[0003]

In the above-described conventional passenger conveyor operating device, the passenger detecting device comprising the photoelectric switch is activated when the passenger is detected, and after a lapse of time which has been added to the passenger transfer time. It was to stop later. However, in the case of a passenger, especially an elderly person with luggage, after the passenger detection device including the photoelectric switch is activated, the passenger may not step on the moving steps, temporarily leave the luggage and take a break. In this case, since the time of the timer elapses, the passenger conveyor stops halfway, and in the case of an elderly man with luggage, there is a danger of falling out of balance and falling.

[0004] An object of the present invention is to provide a passenger conveyor operating device which does not stop the passenger conveyor halfway.

[0005]

In order to achieve the above object, a passenger detection device is provided at the entrance of a passenger conveyor, and when a passenger is detected by the passenger detection device, the passenger conveyor is started and stopped after a predetermined time. In the driving apparatus for a passenger conveyor, the passenger detecting device is provided at least at an interval equal to or larger than the width of the entrance, and is achieved by using a multi-beam sensor including a light projecting unit and a light receiving unit extending in the horizontal direction. Is done.

[0006] Since the multi-beam sensor is provided at the entrance, while the passenger is at the entrance, the count of the timer is not started, and the counting is started only after the passenger gets on the vehicle, and the passenger is reliably transported to the exit. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall plan view of a passenger conveyor provided with an operation device according to an embodiment of the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is an operation circuit diagram.

In FIG. 1, reference numeral 1 denotes a passenger conveyor, and the passenger conveyor 1 includes a balustrade 2, a step 3, an entrance 4, an exit 5, and the like. Reference numeral 6 denotes a multi-beam sensor provided at the entrance 4, and the multi-beam sensor 6
Is composed of a light projecting unit 7 and a light receiving unit 8 which are wider than the width of the entrance 4 and extend in the horizontal direction, and a plurality of beams 9 are projected from the light projecting unit 7 to the light receiving unit 8. ing. 1
Reference numeral 0 denotes a support for supporting the light projecting unit 7, and the light receiving unit 8 is also supported by a similar support. 11 denotes an automatic operation changeover switch, 12 denotes a relay, 13 denotes a timer relay, and 14 denotes an operation start relay.

Now, when a passenger comes to the entrance 4 and blocks the beam 9, the contact 9A turns ON. When the automatic operation changeover switch is turned on, the relay 12 is energized, and the contact 12
Because A is ON, (+)-12A-9A-13
The circuit of (-) is formed, and the timer relay 13 is excited.

As a result, the contact 13A is turned ON, the operation start relay 14 is excited, and the step 3 of the passenger conveyor 1 starts to start. While the passenger is blocking the beam 9, the contact 9A is kept ON, and that state is maintained until the passenger gets on the step 3. When the passenger gets on the step 3 and the light shielding of the beam 9 ends, the timer relay 13 starts from this point.
Start counting and wait 10 minutes after passengers get off exit 5.
It stops in seconds.

As described above, since the timer relay 13 does not start counting while at the entrance 4, even if the elderly person stops at the entrance after starting the passenger conveyor, and then gets on the step 3, the elderly person or the like can surely reach the exit 5. Can be transported.
Further, by supporting the light projecting portion 8 and the light receiving portion 9 with the support 10, it can be used as a safety fence, and there is no need to provide a new fence.

[0012]

According to the present invention, even if an elderly person or the like enters the vehicle after taking a rest at the entrance, the passenger conveyor does not stop halfway and an accident involving the halfway stop can be prevented.
