(First embodiment)
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic diagram showing an overall configuration of a man conveyor according to an embodiment of the present invention. In the figure, a man conveyor 1 includes a plurality of steps 2. The plurality of steps 2 are connected by an endless step chain 3 so as to circulate from one boarding / exiting port 1a to the other boarding / exiting port 1b or from the other boarding / exiting port 1b to one boarding / exiting port 1a. It has become. A drive sprocket 4 is provided in the machine room 1c provided below the entrance floor 1b on the upper floor side, and is wound around the step chain 3 and is driven at the folded portion on the upper floor side of the step chain 3. On the other hand, a driven sprocket 5 that engages and rotates with the step chain 3 is provided at the folded portion on the lower floor side. A guide rail 6 for guiding the step 2 is provided between the drive sprocket 4 and the driven sprocket 5. A driving force from an electric motor 7 serving as a rotational driving device is transmitted to the driving sprocket 4 from a driving chain 8 to circulate and move the step 2 via the step chain 3.

  A balustrade 9 is erected in close proximity to both side ends of the step 2, and an endless moving handrail 10 is attached to the balustrade 9 so as to circulate and move synchronously in the same direction as the step 2. . In order to drive the moving handrail 10, a moving handrail driving device 11 is provided. The moving handrail driving device 11 includes a plurality of roller pairs 11a sandwiching the moving handrail 10, and the driving force from the electric motor 7 is transmitted to the roller pairs 11a by the moving handrail driving chain 12 to be driven. These roller pairs 11a are configured to drive the moving handrail 10 by driving the moving handrail 9 with pressure.

  In addition, the machine room 1c includes an oil supply control device 31 that controls an oil supply timing and an oil supply time based on an operation signal from the electric motor 7, a detection signal for a specific step described later, and the like. An oil supply device 41 for supplying oil to the step chain 3, the drive chain 8, and the movable handrail drive chain 12 under oil supply control is provided.

  The man conveyor 1 according to the present embodiment has one specific step that can be distinguished from other steps among the plurality of steps 2, and the circulation of the specific step, in order to control refueling by the refueling control device 31. It has a detection device that detects laps due to movement.

  FIG. 2 is an explanatory diagram of the specific step and the detection device in the present embodiment. The specific step 21 of the present embodiment shown in the figure has a protruding portion 21a on the outer shape, and by providing the protruding portion 21a, it can be distinguished from other steps. In addition, a limit switch 22 as a detection device is provided at a position where the limit switch 22 can be operated by the protrusion 21 a of the specific step 21. The limit switch 22 is configured such that the projecting portion 21a of the specific step 21 comes into contact with the work piece of the limit switch 22 due to the circular movement of the specific step 21, and the contact of the limit switch 22 is closed. It is input to the fuel supply control device 31.

  Operations of the specific step 21 and the limit switch 22 will be described. When the operation of the man conveyor 1 is started, the specific steps 21 circulate in the truss of the man conveyor 1 as a part of the steps 2 connected endlessly. Since the limit switch 22 that can be operated only by the specific step 21 is provided on the track around which the specific step 21 circulates, the limit switch is provided each time the specific step 21 circulates. 22 is operated. In the present embodiment shown in FIG. 2, the limit switch 22 is shown as the detection device. However, in the man conveyor according to the present invention, if the detection device can detect the specific step 21, the detection means is It is not limited.

  FIG. 3 shows the configuration of an oil supply control device 31 that inputs the detection signal 23 from the limit switch 22 and controls the oil supply device.

  The oil supply control device 31 in the man conveyor 1 of the present embodiment is configured by a microcomputer including a CPU, a ROM, a RAM, and the like. The CPU inputs the program stored in the ROM and the limit switch 22 and other input units. Based on the obtained information, various processes for refueling are performed.

  In such an oil supply control device 31, as shown in FIG. 3, when the operation of the man conveyor 1 is started and the operation detection device 24 detects the operation of the man conveyor 1, the man conveyor operation signal 25 is sent to the oil supply control device 31. Is input. Further, every time the specific step 21 passes the limit switch 22, the detection signal 23 is input to the fuel supply control device 31. Based on these input signals 23 and 25 and the values stored in the storage device in the oil supply control device 31, the oil supply control device 31 performs calculations, turns on the oil supply output signal switch 32, and outputs the oil supply output signal 33. Thus, the fuel supply output relay 42 is operated.

  A specific configuration of the oil supply device 41 controlled by the oil supply control device 31 will be described with reference to FIG. By the operation of the relay contact 42a of the oil supply output relay, power is supplied to the pump motor 43 of the oil supply device 41, and the pump motor 43 of the oil supply device 41 sends out the chain oil 44 to the oil supply pipe 45. The fed chain oil 44 is supplied from the oil supply pipe 45 through the distributor 46 to the drive chain oil supply pipe 47a, the handrail chain oil supply pipe 47b, and the step chain oil supply pipe 47c. Oil 13 is supplied.

  The operation of the man conveyor of the present embodiment having the above-described configuration will be described with reference to FIGS.

  FIG. 5 is a flowchart showing the control for setting the fueling time in the fueling control device 31 of the man conveyor 1 of the present embodiment. As shown in the figure, first, whether or not the refueling time has already been set in the refueling control device, that is, whether or not the refueling time is stored in the storage device (memory) in the refueling control device 31. (Step S10). When the refueling time is not stored in the storage device (memory) in the refueling control device 31, it is confirmed that the man conveyor 1 is in operation (step S20). When the refueling time is stored, it is determined whether or not the refueling time is to be changed. When the refueling time can be changed, the refueling time in the memory is erased and the process returns to step S10. . If the refueling time is not changed, the processing flow can be terminated.

  In step S20, it is determined whether or not the man conveyor 1 is operating based on whether or not the man conveyor operation signal 25 is input from the operation detecting device 24. If the man conveyor 1 is operating, a specific step is detected. Waiting for the detection signal 23 from the limit switch 22 (step S30).

  Then, the step 2 is circulated and moved by the operation of the man conveyor 1, and the timing of the refueling time is started when the specific step 21 pushes down the operating piece of the limit switch 22 and the detection signal 23 is input (step). S40). As time elapses, the specific step 21 circulates and waits for the next input of the detection signal 23 from the limit switch 22 (step S60), and the detection signal 23 from the limit switch 22 is continued. Next time is input, the time measurement is finished (step S70). The time measured is set as the oil supply time, the value of the oil supply time is stored in the internal memory of the oil supply control device (step S80), and the processing flow is ended. In addition, when a man conveyor stops during oiling time measurement (step S50), the time measurement of oiling time is stopped and it returns to step S20.

  The oil supply control in the man conveyor of the present embodiment in which the oil supply time is set by the control flow shown in FIG. 5 will be described with reference to the flowchart of FIG.

  First, it is determined whether or not the man conveyor 1 is in operation (step S110). When the man conveyor 1 is in operation, the operation time of the man conveyor is added in the fuel supply control device 31, and the accumulated operation time of the man conveyor is calculated. (Step S120).

  Next, it is determined whether or not the cumulative operating time of the man conveyor has reached a fueling interval time that is set in advance and stored in the storage device in the fueling control device 31 (step S130). When the accumulated operating time of the man conveyor has reached the fueling interval time, the fueling control device 31 outputs the fueling output signal 33 to the fueling output relay 42 to start fueling. (Step S140).

  The time measurement is started in the oil supply control device 31 from the time when the oil supply is started in the step S140, the oil supply time from the start of oil supply, and the oil supply time set by the processing flow shown in FIG. 5 and stored in the recording device. Are compared to determine whether or not the refueling time from the start of refueling has reached a preset refueling (step S150).

  If the refueling time from the start of refueling has reached a predetermined refueling, the refueling is stopped (step S160), the accumulated man conveyor operating time is cleared (step S180), and the process returns to step S110. On the other hand, after the start of refueling, if the refueling time from the start of refueling has not reached the preset refueling, it is determined whether or not the man conveyor 1 is in operation (step S170) and is in operation. In this case, the time for refueling from the start of refueling is continued. On the other hand, if the man conveyor 1 is not in operation, the refueling is stopped and the process returns to step S110.

  Thus, the man conveyor according to the present embodiment sets the refueling time by measuring the time required for the specific step 21 to circulate, so that an operator who measures the moving speed of the step, the height of the floor, etc., as with the conventional man conveyor, measures it. There is no need to do this, and the refueling time can be set automatically.

  In the present embodiment, the refueling time set in the refueling control device 31 can be set as the refueling time by adding a margin time to the time required for the specific step 21 to make a round. That is, in step S80 of the flowchart shown in FIG. 5, the value of the refueling time can be stored in the internal memory of the refueling control device 31 as the time obtained by adding the extra time to the measured time and the refueling time. In this way, the lubrication control device 31 stores a time obtained by adding a certain margin time to the measured time, and sets the lubrication time of the man conveyor 1 so that the lubrication control device 31 outputs the lubrication output signal 33. Therefore, it is possible to reliably prevent the oil leakage that may occur due to a delay in the time until the oil supply device 41 actually starts the oil supply.

  Moreover, in this embodiment, the said oil supply control apparatus 31 can also perform control which complete | finishes oil supply after the time which the said specific step 21 circulates by several turns. That is, in step S80 of the flowchart shown in FIG. 5, a time that is an integral multiple of the time counted as the time for which the specific step 21 makes one round, or a time obtained by adding a margin time to the integral multiple and a refueling time As a result, the value of the fueling time can be stored in the internal memory of the fueling control device 31. In this way, the time required for the specific step 21 to circulate several times is stored in the refueling control device 31 and set as the refueling time of the man conveyor 1 so that the step chain 3 circulates within the man conveyor 1 the specified number of times. Therefore, even if the amount of oil supplied from the oil supply device 41 is small, a sufficient amount of oil can be supplied.

  Next, a man conveyor according to a second embodiment of the present invention will be described.

  In the man conveyor according to the present embodiment, after a predetermined refueling interval time has elapsed for the refueling control device 31, refueling is started when a signal from the detection device is input, and the specific step circulates. Then, when the signal from the detection device is input, control for terminating the refueling is performed. This is because the specific step 21 circulates during the time required to supply oil over the entire circumference of the step chain 3 in consideration of supplying oil to the step chain 3 having the longest length among the oil supply devices. Since it is the same as the time, the specific step 21 is detected by the detection device (limit switch 22) without previously setting and storing the refueling time in the refueling control device 31 as in the control of the refueling control device 31 in the first embodiment. ) Is detected, and the lubrication time is controlled by the detection signal.

  The man conveyor of this embodiment can use the thing of the structure shown to FIGS. 1-4, and in order to avoid a duplicate description, description of the structure of the man conveyor shown in FIGS. 1-4 is abbreviate | omitted below.

  The oil supply control in the man conveyor in the present embodiment will be described with reference to the flowchart of FIG.

  First, it is determined whether or not the man conveyor 1 is in operation (step S210). When the man conveyor 1 is in operation, the operation time of the man conveyor is added in the fuel supply control device 31, and the accumulated operation time of the man conveyor is calculated. (Step S220).

Next, it is determined whether or not the cumulative operating time of the man conveyor has reached a fueling interval time that is set in advance and stored in the storage device in the fueling control device 31 (step S230). When the accumulated operating time of the man conveyor has reached the refueling interval time, it waits for a detection signal 23 from the limit switch 22 that detects a specific step, and determines whether or not this detection signal 23 has been input (step S240). )
When the detection signal 23 is input to the fuel supply control device 31 in step S240, the fuel supply control device 31 outputs the fuel supply output signal 33 as the fuel supply output relay 42 to start fuel supply (step S250).

  After refueling is started in step S250, the specific step 21 circulates over time and waits for the next input of the detection signal 23 from the limit switch 22 (step S260). Next, when it is input, the refueling is stopped (step S270), the accumulated operation time of the man conveyor 1 is cleared (step S290), and the process returns to step S210. On the other hand, it is determined whether or not the man conveyor 1 is in operation even after the start of refueling (step S280). If the man conveyor 1 is in operation, it waits for the detection signal 23 from the limit switch 22 to be input next. . On the other hand, if the man conveyor 1 is not in operation, the refueling is stopped and the process returns to step S210.

  Thus, the man conveyor according to the present embodiment can supply oil for a time during which the step chain 3 circulates in the man conveyor 1 by simple control without setting the oil supply time. Further, as in the case of the man conveyor of the first embodiment, there is no need for the operator to measure the moving speed of the steps, the floor height, etc., and the refueling time can be set automatically.

  Further, in the present embodiment, when the detection signal 23 from the limit switch 22 is input to the fuel supply control device 31, the fuel supply is started, and the specific step circulates to detect the detection signal from the limit switch 22. It is also possible to perform control to end the refueling when a margin time elapses after 23 is input. That is, in step S260 of the flowchart shown in FIG. 7, the refueling is stopped after a further time has elapsed from the time when the detection signal 23 is next input. In this way, by performing control to stop fueling after a lapse of the surplus time, a time delay from when the fueling control device 31 outputs the fueling output signal 33 to when the fueling device 41 actually starts fueling is delayed. Thus, it is possible to reliably prevent oil supply leakage that may occur.

  Moreover, in this embodiment, the said fuel supply control apparatus 31 can also perform control which complete | finishes fuel supply after progress of the time for a specific step to circulate several times. That is, in step S260 of the flowchart shown in FIG. 7, it is counted that the detection signal 23 has been input, and after the number of counts reaches several times or after a further time has passed since the number of times reached. Stop refueling. In this way, the fuel can be supplied for the time that the step chain 3 circulates in the man conveyor 1 the designated number of times, so that a sufficient amount of oil can be supplied even if the oil supply amount of the oil supply device 41 is small.

  Next, a third embodiment of the present invention will be described.

  During operation of the man conveyor 1 according to the present invention, the operation of the man conveyor 1 may be stopped when the oil supply device 41 supplies oil to the step chain 3 or the like. For example, an automatic operation device that automatically stops the operation of the man conveyor when an emergency stop switch provided on the man conveyor 1 is activated to ensure safety, or when there is no passenger by detecting the presence or absence of passengers Such as when is activated. Even in such a case, it is required to supply oil to the step chain 3 and the like without wasting oil and without oil leakage.

  Therefore, in the man conveyor of the present embodiment, when the man conveyor 1 stops during refueling, the refueling control device 31 stops the refueling of the refueling device 41 and also supplies the already refueled time or the remaining refueling time. It is possible to perform control for storing and refueling at the next start of the man conveyor and performing refueling by the remaining refueling time obtained by subtracting the already refueled time from the set refueling time.

  Such control will be described with reference to the flowcharts shown in FIGS. The control flow shown in FIG. 8 and FIG. 9 is basically the same as the control flow described with reference to FIG. 6. The same steps as those in FIG. Omitted.

  In FIG. 8, when refueling is started in step S140 and refueling is continued (step S150), as shown in FIG. 9, it is detected whether the man conveyor 1 is in operation (step S171) and is in operation. Returns to step S150 and continues refueling. On the other hand, when the man conveyor 1 is not operating, refueling is stopped (step S172), and the refueling time from the start of refueling is stored in the refueling control device 31 (step S173). In this step S173, the remaining fueling time obtained by subtracting the already fueled time from the set fueling time can also be stored.

  While the refueling is stopped, it is detected whether or not the man conveyor 1 is in operation (step S174). If the man conveyor 1 is activated and in operation, the operation direction is the same as the previous operation direction. (Step S175), if the operation direction is the same, refueling is started (step S176), the set refueling time stored in the refueling control device 31 and the refueling at the previous operation Refueling is performed based on the remaining oiling time calculated from the starting oiling time or the remaining oiling time stored in the oiling control device 31. By performing such control, even when the operation of the man conveyor 1 is stopped during refueling, refueling can be continued at the next start-up, and the refueling time can be made appropriate.

  If the operation direction of the activated man conveyor is opposite to the previous operation direction in step S175, the refueling time from the start of refueling stored in the refueling control device 31 or the remaining refueling time is cleared (S177). ) Refueling according to the set lubrication time. By performing such control, the operation of the man conveyor 1 can be stopped during refueling, and refueling can be performed even when the operation direction is changed.

  Next, a fourth embodiment of the present invention will be described.

  As in the second embodiment described with reference to FIG. 6, even when it is detected that the specific step 21 passes the detection device (limit switch 22) and the refueling time is controlled by the detection signal, The operation of the man conveyor 1 may be stopped during refueling. Even in such a case, it is required to supply oil to the step chain 3 and the like without wasting oil and without oil leakage.

  Therefore, in the man conveyor of the present embodiment, the fuel supply control device 31 stops the fuel supply by the fuel supply device 41 when the man conveyor 1 stops during the fuel supply, and the fuel supply device 41 is in the state of the fuel supply. It is possible to store the fact that it has occurred, restart the refueling at the next start of the man conveyor, and perform control to end the refueling when the signal from the limit switch 22 is input.

  Such control will be described with reference to the flowcharts shown in FIGS. The control flow shown in FIG. 10 and FIG. 11 is basically the same as the control flow described with reference to FIG. 7. The same steps as those in FIG. Omitted.

  In FIG. 10, when refueling is started in step S250 and refueling is continued (step S260), as shown in FIG. 11, it is detected whether the man conveyor 1 is in operation (step S281) and is in operation. Returns to step S260 and continues refueling. On the other hand, when the man conveyor 1 is stopped, the fueling is stopped and the fact that the fueling device 41 is in the state of fueling is stored.

  While the refueling is stopped, it is detected whether or not the man conveyor 1 is in operation (step S283). If the man conveyor 1 is activated and in operation, the operation direction is the same as the previous operation direction. (Step S284), and if the driving direction is the same, refueling is started (step S285). Then, when the signal from the limit switch 22 is input, the refueling is finished. By performing such control, even when the operation of the man conveyor 1 is stopped during refueling, refueling can be continued at the next start-up, and the refueling time can be made appropriate.

  In step S284, if the operation direction of the started man conveyor is opposite to the previous operation direction, it is cleared that the refueling control device 31 is in a refueling state (S177). When the detection signal 23 is input to the fuel supply control device 31, the fuel supply is started, and when the detection signal 23 is input next, the fuel supply is stopped. By performing such control, the operation of the man conveyor 1 can be stopped during refueling, and refueling can be performed even when the operation direction is changed.
