  The present invention relates to a moving handrail warming device and a moving handrail heating method for a passenger conveyor that control the temperature of the moving handrail of the passenger conveyor.

  Conventionally, the moving speed of a moving handrail may become slow depending on the installation environment or usage conditions of the passenger conveyor. Specifically, when the installation location of the passenger conveyor is in a low temperature environment, or when the passenger conveyor is not frequently activated, the moving handrail becomes hard, and thus the moving speed of the moving handrail becomes slow. In such a case, for example, when the slip rate of the moving handrail and the slip rate of the moving handrail (a parameter indicating the speed difference with respect to the step of the moving handrail) increases due to a shift in the moving speed of the moving handrail and the step, for example, passengers feel uncomfortable. There is a problem.

  Therefore, in order to solve such a problem, a technique for suppressing a shift in moving speed by heating a moving handrail of a passenger conveyor has been proposed (for example, see Patent Document 1). Here, in the prior art described in Patent Document 1, the moving handrail is warmed by ON / OFF control of the heater, which is a heat source, based on each condition or combination conditions such as the outside air temperature, time, and temperature of the moving handrail. .

However, the prior art has the following problems.
In the prior art described in Patent Document 1, the temperature of the moving handrail is not appropriately controlled based on the slip ratio of the moving handrail (hereinafter, abbreviated as the handrail slip ratio).

  Therefore, when the temperature of the moving handrail is excessively heated above the optimum temperature necessary for obtaining a good handrail slip rate that does not cause discomfort to the passengers, or the temperature of the controlled moving handrail may not reach this optimum temperature. As a result, there is a problem that a good handrail slip rate cannot be obtained. In addition, when the moving handrail is excessively heated, there is a problem from the viewpoint of energy saving.

  The present invention has been made to solve the above-described problems, and is capable of adding a handrail to a passenger conveyor that can improve a handrail slip rate while suppressing excessive warming of the handrail. It is an object to obtain a heating device and a moving handrail heating method.

It is a flowchart which shows operation | movement of the moving handrail heating apparatus of the passenger conveyor in Embodiment 1 of this invention.

  Hereinafter, a moving handrail heating device and a moving handrail heating method for a passenger conveyor according to the present invention will be described with reference to the drawings according to a preferred embodiment. In addition, below, although the case where this invention is applied with respect to the escalator which is a specific example of a passenger conveyor is illustrated, it is applicable also to a moving sidewalk.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram of an escalator including a moving handrail warming device 10 for a passenger conveyor according to Embodiment 1 of the present invention.

  In FIG. 1, the truss 1 is constructed between the architectural beams on the upper and lower floors. The truss 1 supports a plurality of steps (steps) 2 connected endlessly. Further, a pair of balustrades 3 are erected on the truss 1 on both sides of the step 2.

  Each balustrade 3 is provided with an endless moving handrail 4 that moves in synchronization with the step 2. The moving handrail 4 moves on the balustrade 3 on its forward path. In addition, the moving handrail 4 is folded at the nual portion at one end of the balustrade 3 and drawn into the balustrade 3, and is pulled out from the lower portion at the other end of the balustrade 3.

  The balustrade 3 is provided with a handrail guide 5 that forms a travel route of the moving handrail 4. The moving handrail 4 travels along the handrail guide 5. A drive device (not shown) that generates power for running the moving handrail 4 is disposed in the truss 1. The moving handrail 4 is conveyed at a constant speed by the driving device.

  Next, the moving handrail warming device 10 of the passenger conveyor (hereinafter abbreviated as the handrail warming device 10) will be described.

  As shown in FIG. 1, the handrail warming device 10 includes a temperature detection unit 11, a temperature adjustment unit 12, a handrail slip ratio detection unit 13, a control unit 14, and a storage unit 15.

  The temperature detector 11 detects a handrail temperature that is the temperature of the moving handrail 4. Specifically, as the temperature detection unit 11, for example, a non-contact type temperature sensor is used so that the temperature of the moving handrail 4 detected in a non-contact manner is set as the handrail temperature.

  Note that the temperature detection unit 11 may be attached to the handrail guide 5 and the temperature of the handrail guide 5 detected by the temperature detection unit 11 may be set as the handrail temperature. In this case, as the temperature detection unit 11, for example, a contact-type temperature sensor may be used.

  The temperature adjusting unit 12 adjusts the handrail temperature by warming the moving handrail 4 or stopping the warming. Specifically, for example, the temperature adjustment unit 12 is configured so that the moving handrail 4 can be heated by applying the conventional techniques described in Patent Documents 1 and 2. That is, for example, a heater may be used as the heat source of the temperature adjustment unit 12 and the moving handrail 4 may be heated by the heat of the heater.

  The control unit 14 controls the operation of the temperature adjustment unit 12 so that the handrail temperature acquired from the temperature detection unit 11 becomes the set temperature stored in the storage unit 15. Specifically, the control unit 14 controls the handrail temperature to be the set temperature by operating or stopping the temperature adjusting unit 12. The set temperature will be described later.

  More specifically, for example, when a heater is used as the heat source of the temperature adjustment unit 12, the control unit 14 controls the handrail temperature to be a set temperature by ON / OFF control of the heater. That is, the control unit 14 warms the moving handrail 4 by turning on the heater if the handrail temperature is lower than the set temperature, while turning the heater off if the handrail temperature is equal to or higher than the set temperature. Stop warming.

  The handrail slip ratio detection unit 13 detects a handrail slip ratio that is a parameter indicating a speed deviation of the moving handrail 4 with respect to the step 2. Specifically, the handrail slip ratio detection unit 13 is configured so that the handrail slip ratio can be detected by applying the conventional technique described in Patent Document 3. That is, for example, the handrail slip ratio detection unit 13 may detect the respective movement speeds of the step 2 and the moving handrail 4 using a speed sensor, and obtain the handrail slip ratio based on the detection result. In this case, the handrail slip rate may be defined by the following equation, for example.

Handrail slip rate (%)
= {1- (moving speed of moving handrail 4 / moving speed of step 2)} × 100

  The control unit 14 performs a set temperature update process. That is, the control unit 14 acquires the handrail slip rate from the handrail slip rate detection unit 13 and the handrail temperature from the temperature detection unit 11 as the first stage of the set temperature update process.

  Subsequently, as a second stage of the set temperature update process, the control unit 14 associates the acquired handrail slip rate and the handrail temperature and writes them in the table of the storage unit 15. Moreover, if the control part 14 performs these 1st steps and 2nd steps, the table of the memory | storage part 15 will contain one set of the data combination which consists of handrail slip ratio and handrail temperature. Furthermore, if the control unit 14 repeatedly executes the first stage and the second stage, the table of the storage unit 15 includes two or more combinations of data including the handrail slip ratio and the handrail temperature. Become.

  Subsequently, as the third stage of the set temperature update process, the control unit 14 extracts the optimum handrail temperature, which is the handrail temperature corresponding to the minimum handrail slip ratio, from the table of the storage unit 15, and uses the extracted optimum handrail temperature. The set temperature is updated by setting the set temperature.

  Further, when the series of set temperature update processing is completed, the control unit 14 stores the handrail slip rate corresponding to the updated set temperature in the storage unit 15 and includes the handrail slip rate and the handrail temperature written in the table. Clear data combinations from the table. By performing such processing, in the next set temperature update process, it is possible to prevent the data written in the table in the previous set temperature update process from being used.

  Moreover, after the set temperature stored in the storage unit 15 is updated as a result of the series of set temperature update processing, the control unit 14 causes the temperature adjustment unit 12 to set the handrail temperature to the updated new set temperature. To control the operation.

  Next, a series of set temperature update processing operations of the handrail warming device 10 will be described with reference to FIG. FIG. 2 is a flowchart showing the operation of the moving handrail heating device 10 for the passenger conveyor in the first embodiment of the present invention. Note that this flowchart is executed a preset number of times at a preset interval (eg, every hour) during a preset time period (eg, a time period determined every day).

  In step S101, the control unit 14 acquires the handrail slip rate from the handrail slip rate detection unit 13, and also acquires the handrail temperature from the temperature detection unit 11, and proceeds to step S102.

  In step S102, the control unit 14 associates the handrail slip rate and the handrail temperature acquired in step S101, writes them in the table of the storage unit 15, and proceeds to step S103.

  In step S103, the control unit 14 determines whether or not the number of executions of this flowchart has reached the set number. If the control unit 14 determines that the number of executions of this flowchart has reached the set number (ie, YES), the control unit 14 proceeds to step S104. On the other hand, when it is determined that the number of executions of this flowchart has not reached the set number (that is, NO), the control unit 14 ends the series of processes. With this configuration, if the set number of times is set to 2 times or more, the table in the storage unit 15 includes two or more combinations of data including the handrail slip ratio and the handrail temperature.

  In step S104, the control unit 14 extracts the optimum handrail temperature that is the handrail temperature corresponding to the minimum handrail slip rate from the table in the storage unit 15, and proceeds to step S105.

  In step S105, the control unit 14 updates the set temperature by setting the optimum handrail temperature extracted in step S104 as the set temperature, and ends the series of processes.

  Note that the control unit 14 may be configured to execute the set temperature update processing operation only when no passenger is on the escalator.

  In this case, the handrail warming device 10 further includes a passenger detection unit that detects the presence of a passenger if a passenger is on the escalator, and the control unit 14 is configured such that the passenger detection unit does not detect the presence of the passenger. Only, the control unit 14 executes the set temperature update processing operation. As a configuration of the passenger detection unit, for example, the presence of a passenger may be detected using sensors provided at the landing entrance and the landing exit of the escalator, or the presence of a passenger is detected using a camera. You may make it do.

  As described above, according to the first embodiment, the temperature detection unit that detects the temperature of the handrail that is the temperature of the moving handrail, the temperature adjustment unit that adjusts the temperature of the handrail, and the handrail that is a parameter indicating the speed deviation of the moving handrail with respect to the steps. A handrail slip ratio detection unit that detects a slip ratio; and a control unit that controls the operation of the temperature adjustment unit so that the handrail temperature detected by the temperature detection unit becomes a set temperature.

  In addition, as the set temperature update process, the control unit acquires the handrail slip rate from the handrail slip rate detection unit, acquires the handrail temperature from the temperature detection unit, and associates the acquired handrail slip rate with the handrail temperature in the table. The optimum handrail temperature, which is the handrail temperature corresponding to the minimum handrail slip rate, is extracted from the written table, and the set temperature is updated by setting the extracted optimum handrail temperature as the set temperature.

  Thereby, it is possible to improve the handrail slip rate while suppressing excessive heating of the moving handrail.
