Abstract

PURPOSE:To carry out the inexpensive highly-safe remote control of a man conveyor without using a supervisory means by providing an operation switching circuit for placing a remote control circuit, operable at the cut-off time of a shutter, out of operation at the open time so as to operate an operating means around a man conveyor, and a means for stopping operation at the cut-off time of the shutter. CONSTITUTION:When an up-operation remote start switch 12 is closed to perform remote up-start, a relay 14 is energized to close a contact 14C, and thereby a relay 16 is energized. At this time, a contact 16a is closed, so that the relay 16 is self-held by (+)-16a-17a-16-(-). Then contacts 16b, 14a are closed, so that a relay 10 is energized by (+)- safety switch group -7-16b-14a-11b-10-(-), and a man conveyor is operated upward. When fire shutters 3, 6 are then opened completely, contacts 3b, 6b are opened, so that a relay is de-energized to open a contact 17a, and the relay 16 is de-energized to open the contact 16b, but operation is continued since contacts 3a, 6a are closed. When the fire shutters 3, 6 are closed, the contacts 3a, 6a are opened, and the man conveyor is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a remote control device for a passenger conveyor that operates the passenger conveyor from a distance.

(Prior Art) Recently, passenger conveyors have become widespread and have become indispensable equipment in department stores, shopping centers, stations, etc.When operating these passenger conveyors, The staff member went to the passenger conveyor side,
This was extremely troublesome as it had to be activated after confirming safety, such as whether or not anyone was on the passenger conveyor.

In order to solve these problems, the
As disclosed in No. 53270, ``Operation management system for passenger conveyors,'' each passenger conveyor is equipped with a television receiver for monitoring the operation status of the passenger conveyor, and a monitoring push button for operating each television receiver is provided. There was one that was equipped with a button and could be operated remotely by linking the pressing operation of the monitoring push button. As a result, only the passenger conveyor to be monitored by the television receiver can be remotely activated.

[Problem to be solved by the invention] As mentioned above, with the conventional equipment, it is necessary to install a television receiver for each passenger conveyor, and in high-rise buildings, the scale of the equipment becomes large, making it difficult to solve the problem. It becomes something that cannot be done. In addition, installing television receivers at key points in a building and reducing the number of television receivers creates problems such as creating blind spots in the monitoring area and not necessarily being safe.

This invention was made to solve the above-mentioned problems, and it is an inexpensive and highly safe method for controlling a man's hair conveyor remotely without using any monitoring means such as a television receiver. The purpose is to obtain a remote control device.

(Means for Solving the Problems) A remote operation device for a passenger conveyor according to the present invention includes a shutter that shuts off an installation space of the passenger conveyor and a general indoor space, and when the shutter is shut off, remote control of the passenger conveyor is provided. an operation switching circuit that disables the operation of the remote control circuit when the shutter is opened and enables operation of a passenger conveyor operating means installed near the passenger conveyor; and an operation stop means for stopping the operation when the shutter is shut off.

[Function] According to this invention, when the shutter is shut off and the person is removed from the person conveyor and safety is established, the person conveyor can be remotely controlled by the remote control circuit, and after the shutter is opened after the remote control is started, When the remote control is stopped, the operation of the passenger conveyor is switched to the operating means as usual, and when the shutter is shut off, the operation of the passenger conveyor is automatically stopped by the operation stop means.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure is an installation diagram of the passenger conveyor and shutter, (r)
, (2) is a man conveyor, (3), (4) and (5).

(6) is a fire prevention shutter that isolates the space where the passenger conveyor is installed on each floor from the general indoor space.

FIG. 2 is a circuit diagram of a remote control device for a passenger conveyor according to this embodiment.

In the figure, (!la) and (6a) are the contacts that close when each fire shutter opens, and (3b) and (6b)
is the contact that closes when each fire shutter is shut off, (7) is the stop switch installed near the passenger conveyor, (8) is the LIP operation start switch of the passenger conveyor, and (9) is the DOWN operation start switch of the passenger conveyor. Both switches (8) and (9) are installed near the passenger conveyor. (12) is an up operation remote start switch,
(13) is a DOWN operation remote start switch, (14) is a remote UP relay, (15) is a remote DOWN relay, (1
6) is a remote management relay, and (17) is a fire protection shutter relay.

Next, the operation of this embodiment will be explained according to the above configuration. First, there are fire shutters (3) and (4) that separate the space where the passenger conveyor is installed from the general indoor space.

(5) and (8) are based on the Construction Order of the Building Standards Act, and fire shutters (3) and (6) are required for passenger conveyor (1), and fire shutters (4) and (5) are required for passenger conveyor (2), respectively. As is known, when the fire protection shutters of these combinations are closed, the passenger conveyor must be stopped.

Each of the above fire shutters (3), (4), (5)
, (6) is open and mancon hair (1) ,
When operating (2) in UP mode, fire shutter (3)
, (4), (5), and (δ) are in the open state, so the contacts (3a) and (6a) are in the closed state. Therefore, when the UP operation start switch (8) is closed, (+
) - Safety switch group - Stop switch (7) - Contact (3a
), (6a) - UP operation start switch (8) - Normally closed contact (llb) of relay (11) - Relay (10)
-(-) UP operation circuit is formed, and a motor and an electromagnetic brake (not shown) are operated in the IIP direction by energizing the relay (10). At this time, the normally closed contact (10a) of the relay (10) closes, and the (+) - safety switch group - (7)
(3a) -16a) -(10a) -(ll
b) A self-holding circuit of -(10)-(-) is formed,
Even if the UP operation start switch (8) is released, the UP operation continues.

Next, the procedure for remote activation will be explained. At this time, the prerequisite is that the fire shutters (3) and (8) are closed, and the contacts (:+b) and (ab) are contacts that operate in the exact opposite way to the above contacts (3a) and (6a). This is the contact that is made when the fire shutter is fully open. The above (8) and (9) are activation switches installed on the passenger conveyor side, but (12) is a switch that remotely activates UP, and (13) is the same remote DOW switch.
This is the N activation switch. Fire shutters (3),, (8)
Since (3b) and (6b) are closed due to the closure of ('') −(3b)−(6b) −(17) −(−)
The relay (17) is energized and the contacts (17a) and (1
7b) is closed. Now, when you close the UP operation remote start switch (12) to remotely start UP, (17b) is closed, so (+) - (17b) - (12) - (
15b) -(14) -(-) energizes the relay (14) and closes the contact (14c), so ('') -(14c
) (17a) -(16) -(-) relay (
16) is energized. At this time, the contact (16a) closes, so (+) -(16a) -(17a) -(15)
-(-) makes (16) self-maintaining. Then, the contact point (I
[ib), (14a) closes, so (+) - safety switch group - (7) - (16b) - (14a) - (
llb) -(10) (In step 1, the relay (lO) is energized, and thereafter the passenger conveyor is operated in UP mode in the same way as above.

Next, in order to allow passengers to get on the passenger conveyor, the fire shutters (3) and (6) are opened and when they are fully opened, the contacts (3b) and (6b) open and the relay (17
) is deenergized and the contact (17a) is closed, so the relay (16
) is deenergized and the contact (16b) is closed. However, the contact (3a
) and (6a) are closed first, the operation of the passenger conveyor is continued and is operated in the same circuit as a normal passenger conveyor. Next, when the fire shutters (3), ([i) close, the contacts (3a), ('6a) open, so the relay (lO) is deenergized and the passenger conveyor stops.

In the above embodiment, if there is no means to confirm whether the passenger conveyor is stopped when the fire shutter is closed or if there is no person near the passenger conveyor after the fire shutter is closed,
A known device for gently stopping the man-con hair may be added to the stopping circuit.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to remotely control the passenger conveyor only when the shutter is shut off when the person is removed from the passenger conveyor, so that a staff member patrols each passenger conveyor to confirm the safety of the passenger conveyor. There is an effect that a remote control device for a passenger conveyor can be constructed with an inexpensive and simple configuration and excellent safety without having to install a special remote monitoring means on each passenger conveyor.
