Abstract

(57) [Summary] [Purpose] To provide an automatic oiling device for a passenger conveyor capable of supplying a necessary amount of oil to a worn portion. [Configuration] Timer 2 for measuring the driving time of the passenger conveyor
And a control device 3 for controlling the lubrication device 4, and a control device 3 for controlling the lubrication device 4. After the passenger conveyor is activated, the amount of oil corresponding to the previous drive time is replenished.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic lubricator for a passenger conveyor that supplies a necessary amount of oil to a worn portion.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, as a refueling device for a passenger conveyor, as disclosed in Japanese Utility Model Publication No. 60-30559, the number of times of operation is counted, and when a predetermined number of times of operation is reached, a certain amount of oil is refueled to a worn portion There is.

[0003]

[Problems to be solved by the device]

 However, in the method described in the above-mentioned conventional technique, the passenger conveyor may stop immediately after the refueling because the refueling is performed several times a day. In such a case, the worn part of the passenger conveyor becomes overfilled with oil, and oil drips while the passenger conveyor is at rest, or the oil is splashed by the next day's activation, and the oil drips or spills. May seep into the building and pollute the building.

It is an object of the present invention to provide an automatic fueling device for a passenger conveyor that can supply a necessary amount of oil to a worn portion.

[0005]

[Means for Solving the Problems]

 The object of the present invention is to provide a timer for measuring the driving time of the passenger conveyor in an automatic fueling device for a passenger conveyor that refuels a worn portion of a landing conveyor having endlessly connected steps, and to refuel the worn portion. This is achieved by providing an oil supply device and a control device that controls the oil supply device, and by supplying an amount of oil corresponding to the previous drive time after the passenger conveyor is activated.

[0006]

With the above configuration, the timer counts the driving time of the passenger conveyor and transmits the counted time to the control device of the fueling device. The control device sets the amount of oil to be supplied corresponding to the sent time data, and outputs a command signal to supply the set amount of oil to the wear portion. Responding to this signal, the refueling device will refuel the abraded part in the required amount the next time the passenger conveyor is activated.

[0007]

【Example】

 An embodiment of an automatic fueling device for a passenger conveyor according to the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view of an automatic oiling apparatus of the present invention.

In the machine room, there are a control device 1 for controlling each device of the escalator, a timer 2 for counting the driving time of the escalator and outputting the counted time when the escalator is stopped, a control of the oil supply device and a timer 2. The oil supply control device 3 that receives the output of the oil supply and sets the amount of oil to be supplied, the oil supply device 4 that supplies oil to each part based on the command of the oil supply control device 3, and the oil supply device 4 that is connected to the oil supply device 4 The oil supply pipes 5, 6, 7, 8, 9 and the like for carrying the oil are stored. Further, in this embodiment, a step chain 10 for driving a step for supplying oil as a worn portion, a main chain 11 for driving the handrail 15, a tension chain 12, a drive chain 13, a motor for the step chain 10 are provided. The driving chain 14 that transmits the drive of 16 is also housed in the machine room.

Next, the operation will be described.

The timer 2 receives a signal from the escalator control device 1 and starts counting from the time when the escalator starts to start by turning on a start switch (not shown), and then turns on the escalator by turning on a stop switch (not shown). Counts the time until stops. The time counted by the timer 2 is transmitted to the refueling control device 3, and then the timer 2 is reset. The refueling control device 3 sets the amount of refueling to each worn portion in correspondence with the transmitted time. After that, when the escalator is activated, the refueling control device 3 operates the refueling device 4 to deliver the set amount of oil through the oil pipes 5, 6, 7, 8 and 9 to the step chain 10, the main chain 11, Lubricate the tension chain 12, drive chain 13, and driving chain 14.

As described above, according to this embodiment, it becomes possible to supply the necessary amount of oil to the wear portion. The above-mentioned refueling method is not particularly limited, and many methods are conceivable such as refueling immediately after starting, several minutes after starting, or every few minutes, but any method can be used. The effect of the present invention can be obtained.

[0012]

[Effect of the device]

 According to the present invention, the amount of oil corresponding to the time when the passenger conveyor operates last time is supplied to each worn part after the next time the passenger conveyor is started, so that the necessary amount of oil can be supplied and the effect of preventing excessive oil supply and splashing is achieved. There is.
