Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in operating switch devices for passenger conveyors such as escalators and moving roads.

First, a conventional operation switch device for a passenger conveyor will be explained with reference to FIGS. 1 and 2.

In Fig. 1, 1 is the main body of the passenger conveyor, 1a is the railing of the main body 1 of the passenger conveyor, 2a and 2b are the landing areas of the passenger conveyors on the upper and lower floors, and 3a and 3b are the ends on the lower boarding bath side of the above handrail 1a. This is an operation switch device provided in each section. As shown in FIG. 2, the operation switch device is provided with an emergency stop button 4, a single-cylinder start switch 5, and a single-cylinder stop switch 6 on a panel 7, respectively. The emergency stop button 4 is usually covered with a cover to prevent abuse.

The starting cylinder 1 lock switch 5 is used to operate the passenger conveyor main body 1 upward when the key is inserted and turned to the right, and to descend when the key is turned to the left.
Insert the above key and turn it to the right to stop the passenger conveyor body 1, and if you turn it to the left, the operation switch 3a on the lower floor will activate the buzzer or bell-like alarm on the opposite floor, such as the upper floor. It is something to do.

The conventional passenger conveyor operation switch device configured as described above includes an emergency stop button 4, a starting cylinder lock switch 5 for starting raising and lowering, and a stopping cylinder lock switch 5 for stopping and warning. It is equipped with a switch 6. It is well known that the start switch and stop switch are locked to prevent them from being operated by ordinary passengers, so they are equipped with cylinder locks. The alarm switch is operated on either the upper or lower floor of the passenger conveyor, and when operated, the purpose is to notify the operating side to start the passenger conveyor from the operating side to the non-operating side. A buzzer or bell sounds on the side, that is, on the non-operating panel, to alert people near the landing area.As mentioned above, the conventional passenger conveyor operation switch device has multiple operating devices. When starting a single passenger conveyor, it is necessary to insert and remove keys into multiple cylinder single lock switches and turn them, making the operation cumbersome.
In addition, there was a risk that the normal operating procedure of operating the starting cylinder one-lock switch without operating the alarm switch would not be performed.

This invention was made in view of the above-mentioned circumstances, and by providing an operation switch with multiple types of functions such as lifting, stopping, and alarm, it is possible to eliminate the troublesome operation. It is an object of the present invention to provide an operation switch device for a passenger conveyor that can prevent operations performed in an incorrect procedure.

Hereinafter, one embodiment of the present invention will be explained with reference to FIGS. 3 to 5.

In FIG. 3, the same reference numerals as those in FIG. 2 indicate the same or corresponding parts, and 8 is a one cylinder lock switch for operation which also has the functions of starting and stopping the lift and warning. This one cylinder lock switch 8 is constructed as shown in FIG. That is, in Fig. 4, 8a is a shilling lock, 9 is an alarm limit switch that closes when the key is inserted into the cylinder lock 8a, and 1° is a cam 13b provided on the cylinder lock 8a when the key is inserted and pressed. A stop limit switch 11.12 opens the circuit, and 11.12 is a starting rising/lowering limit switch that closes when a cam 13a provided on the cylinder lock 8a rotates when the key is turned to the right or left. Moreover, FIG. 5 is a circuit diagram of the above switch, and 9 a , 10 a +
11 a+ 12 a are limit switches 9, 10,
11.12 contacts, 14 is a bell or buzzer-like indicator, 15.16 is a relay, 15a, 16a are relays 1
5.16 contacts.

It should be noted that the operation switch device according to this embodiment is provided as an operation panel on the top of the handrail of the passenger conveyor and at the end on the lower landing side, respectively, similar to the conventional device shown in FIG.

Next, the operation of this embodiment will be explained. When the passenger conveyor body is stopped, insert the key into the cylinder lock 8a,
The contact 9a of the alarm limit switch 9 is opened and the alarm 14 on the non-operated floor continues to ring. Next, when the key is turned to the right or left, the cam 13a rotates from the neutral state in the direction in which the key is turned, and the contact 11a or 12a of the start-up raising or lowering limit switch 11 or 12 closes.

When the contact 11a of the starting lift limit switch 11 is closed, the relay 15 is energized to rotate the electric motor (not shown) of the passenger conveyor drive device in the upward direction, and the brake (not shown) is energized. and then launched in an upward direction. Contact 12 of starting lower limit switch 12
When a is closed, relay 16 is energized and the passenger conveyor is started in the downward direction in the same manner as for the upward movement described above. -Also, by setting the key so that it can be removed from the cylinder lock 8a only in the neutral position shown in Fig. 3, the key can be removed (and
The contact 11a or 12IL of 1 or 12 is opened, but the contact 15a or 16a remains closed, so that -15 or 16 can be maintained in an energized state. Therefore, even if the key is removed, the passenger conveyor remains in operation. If you are having trouble returning the key to the removal position, insert the return spring into the cylinder lock 8 and turn it to the left.

Turn it clockwise to start it, then release it and the return spring will return to the original neutral position.
You can easily remove the key. To further stop the passenger conveyor, insert the key into the cylinder lock 8aK and press it, and the cam 13b will activate the stop limit switch 1.
0 contact 10a opens, the energized relay 15 or 16 is deenergized, and the ℃ passenger conveyor stops. after that,
When you let go of the key, a spring (not shown) will return the key to its original position, so pull out the key (.

As mentioned above, in this embodiment, all operations such as displaying, raising, lowering, and stopping the passenger conveyor can be performed with one operation cylinder and one lock switch. In addition, for a visitor conveyor where lighting equipment is installed at both ends of the handrail, if the lighting equipment is turned on when activated, the emergency stop button 4 shown in Fig. Only two switches 8 are required, and the number of single cylinder lock switches can be reduced compared to the conventional one shown in FIG.

Although the above embodiment describes the case where the operation switch device is provided on the handrail, the present invention can also be applied to a case where the operation switch device is provided on a pillar provided separately from the handrail at or near the landing of a passenger conveyor. Moreover, it can be applied not only to escalators but also to moving roads where the treads move horizontally, and even in these cases, the same effect as that of the embodiment can be obtained.

As explained above, in the passenger conveyor operation switch device according to the present invention, the operation switch has multiple types of functions such as raising/lowering, stopping, and favorability, so the number of operation switches can be reduced, and the alarm can be activated. This has the effect of preventing erroneous operations such as starting the passenger conveyor and improving safety during startup.
