Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary operation switch for a passenger conveyor, and more particularly to a temporary operation switch for a passenger conveyor suitable for a stepwise renewal method for the passenger conveyor.

[0002]

2. Description of the Related Art Operation switches for passenger conveyors such as escalator and auto line have been conventionally disclosed in Japanese Patent Laid-Open No. 2000-26.
No. 4566 discloses a mounting hole provided at a predetermined position of an inner panel stretched on a balustrade of a passenger conveyor, an operation switch is directly inserted into the mounting hole, and the operation switch is fixed to the inner panel using a fixing member. The technology to do is proposed.

Further, in the technology related to the renewal of the passenger conveyor, conventionally, the entire renewal work of the passenger conveyor is divided into a plurality of steps for renewing each predetermined portion of the passenger conveyor, and a plurality of steps are performed during a time period when the passenger conveyor is not used. A passenger conveyor renewal method has been proposed in which each of the above steps is completed individually.

[0004]

Since the renewal of the passenger conveyor in the above-mentioned prior art is changed from the relay control system to the microcomputer control, when the new control panel is renewed, the old operation switch corresponding to the relay control is converted into a microcomputer. The new control panel could not be used due to differences in functions and contact configurations, and it was necessary to replace it with a new operation switch.

Further, if a new operation switch is attached to the old balustrade before renewal and used, the problem arises that the operation switch is dirty or damaged after the balustrade is renewed.

An object of the present invention is to provide a temporary operation switch for a passenger conveyor that can be used from the completion of renewal of a control panel to the completion of renewal of a balustrade.

[0007]

In order to achieve the above object, the invention of claim 1 has a plurality of steps connected endlessly to move a passenger and a driving mechanism for driving these steps. A drive device having, a drive panel of the drive device is controlled, a control panel included in the drive device, a lighting unit provided on an upper part of the passenger conveyor, a balustrade provided on both sides of the step, and a balustrade of these balustrades. Temporary installation of the passenger conveyor in the renewal method, which is provided along each upper part and includes a handrail that moves in synchronization with the plurality of steps, and is divided into a plurality of steps for renewing each predetermined portion of the passenger conveyor. Except for the balustrade and the step, at least when the control panel is completely renewed to a new control panel, And the operation switch attached to the balustrade,
A cable with a connector for connecting the operation switch and the new control panel is provided.

According to a second aspect of the present invention, after the renewal of the new control panel is completed, the operation switch is detached from the balustrade and used as a working operation device.

Because of this, the operation switch attached to the old balustrade is used as a temporary operation switch until the renewal of the new control panel is completed and the renewal of the balustrade is completed. Since a new operation switch is used when the renewal is completed, it can be used as a temporary operation switch and can be used as a work operation device when the balustrade is renewed, so efficient renewal work can be performed.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS.
It will be described with reference to FIG.

FIG. 1 is a side view of a lower portion of an escalator before a balustrade renewal showing an embodiment of a temporary operation switch for a passenger conveyor according to the present invention, FIG. 2 is a front view of the temporary operation switch used in FIG. 1, and FIG. 3 is FIG. 4 is a sectional view taken along line AA of FIG. 4, FIG. 4 is a flow chart for explaining the procedure of the stepwise renewal of the escalator, and FIG. 5 is a side view of the lower portion of the escalator corresponding to FIG.

1 to 3, an existing operation switch 3 connected to an existing control panel (not shown) of a relay control system is attached between columns 2 provided in the balustrade 1, and the existing control panel is controlled by a microcomputer. When a new control panel (not shown) of the system is renewed, the temporary operation switch 4 is mounted between the pillars 2 below the existing operation switch 3. Here, the temporary operation switch 4 has an integral structure with a cover case, is fixed by tightening the mounting bolts 5 from the inside of the case to the pillars 4 on both sides, and is mounted on a new control panel (not shown) of the microcomputer control system. It has a connector 6 that is detachably connected.

Next, the stepwise renewal method of the escalator will be described.

In FIG. 4, firstly, the control renewal procedure for renewing from an existing control panel of a relay control system to a new control panel of a microcomputer control system is as follows: an existing control panel (not shown), a motor (not shown), a drive device (not shown), etc. In addition to removing the existing operation switch 3, the wiring including the connection line between the existing operation switch 3 and the existing control panel (not shown) is cut (procedure S1), a new control panel (not shown), a motor (not shown), a drive device (not shown), etc. are attached, and Connection work is performed (procedure S2), as described above, the temporary operation switch 4 is mounted between the pillars 2 which are the balustrade parts 1, and the temporary operation switch 4 and a new control panel (not shown) are connected via the connector 6. The operating state is confirmed by the temporary operation switch 4 (step S3), and the control renewal is completed.

When the control renewal is completed,
Since it becomes possible to use the escalator, it can be handed over to the customer.

As a next step, the steps (not shown) and the procedure of the balustrade renewal for renewing the balustrade part 1 to a new one are to remove the temporary operation switch 4 from the pillar 2 (step S4), and then move the temporary operation switch 4 to the floor or the like. And a re-wiring with a new control panel (not shown) so that it can be used as a working operation device (step S5), and a balustrade including steps and columns 2 (not shown) using the temporary operation switch 4 as a working operation device. Work to remove the 1st grade etc. (Procedure S
6) In addition to performing steps (not shown) and installing the new balustrade 7, etc., as shown in FIG. 5, the new operation switch 8 is installed in the outer deck 9 of the new balustrade 7 (step S
7) The wiring of the new control panel (not shown) and the temporary operation switch 4 is removed, and the wiring of the new control panel (not shown) and the new operation switch 8 is connected to confirm the operating state of the new operation switch 8 (procedure). S8), the work of redesigning the balustrade is completed.

According to this embodiment, since the escalator can be used by the temporary operation switch 4 after the control renewal of step S3 is completed and the balustrade renewal of step S4 is started, the time of the parapet renewal is delayed. Does not bother customers and escalator users.

[0018]

According to the present invention, the operation switch attached to the old balustrade part is used as a temporary operation switch during the period from the completion of the renewal to the new control panel to the completion of the renewal of the balustrade part. Since the new operation switch is used when the renewal of the hanging part is completed, it can be used as a temporary operation switch and can be used as a work driving device when the balustrade part is renewed, so efficient renewal work can be performed.
