[0008] A passenger conveyor according to an embodiment of the present invention will be described with reference to Figures 1 to 5. In this embodiment, an escalator 10 will be described as the passenger conveyor. (1) Escalator 10 The overall structure of escalator 10 will be described with reference to Fig. 1. Fig. 1 is an explanatory diagram of escalator 10 as viewed from the left side. However, in order to make the internal structure of escalator 10 easier to understand, illustration of members on the right side of escalator 10 is omitted. Note that when describing the front-to-rear direction of escalator 10, it is assumed that the viewer is looking up from a lower floor to an upper floor, with the upper floor being the front side and the lower floor being the rear side.

[0009] As shown in FIG. 1, a truss 12, which is the framework of an escalator 10, is supported by support angles 2 and 3 across the upper and lower floors of a building 1.

[0010] Inside the upper floor machine room 14 at the top end of the truss 12, there are provided a drive unit 18 for driving the steps 30, a pair of left and right step sprockets 24, 24, and a pair of left and right first handrail sprockets 27, 27. This drive unit 18 has a motor 20, a reducer, an output sprocket 19 attached to the output shaft of the reducer, and a disk-type electromagnetic brake 23 that stops the rotation of the motor 20 and maintains the stopped state. The pair of left and right step sprockets 24 and the pair of left and right first handrail sprockets 27, 27 rotate in synchronization with the rotation of the output sprocket 19. The structure for rotating in synchronization will be described in detail later. Inside the upper floor machine room 14, there is also provided a control device 50 that controls the drive unit 18 consisting of the motor 20, the electromagnetic brake 23, etc.

[0011] As shown in FIG. 1, a pair of left and right step driven sprockets 26, 26 are provided in the lower floor machine room 16 at the lower end of the truss 12. A pair of left and right endless step chains 28, 28 are stretched between the pair of left and right step sprockets 24, 24 on the upper floor side and the pair of left and right step driven sprockets 26, 26 on the lower floor side. First wheels 301 of a plurality of steps 30 are attached at equal intervals to the pair of left and right step chains 28, 28. When the motor 20 rotates, the first wheels 301 of the steps 30 run on a guide rail (not shown) fixed to the truss 12, and the second wheels 302 run on a guide rail 25 fixed to the truss 12.

[0012] As shown in Fig. 1, a pair of left and right balustrades 36, 36 are erected on the left and right sides of the truss 12. A handrail rail 39 is provided on the top of the balustrade 36, and an endless handrail belt 38 moves along this handrail rail 39. An upper floor front skirt guard 40 is provided on the lower front part of the upper floor side of the balustrade 36, and a lower floor front skirt guard 42 is provided on the lower front part of the lower floor side, and inlets 46, 48, which are entrances and exits for the handrail belt 38, protrude from the front skirt guards 40, 42, respectively.

[0013] A skirt guard 44 is provided on the lower side of the balustrade 36, and the steps 30 run between a pair of left and right skirt guards 44, 44.

[0014] As shown in Figure 1, when the steps 30 are rising, the pair of left and right handrail belts 38 each enter the front skirt guard 40 from the inlet portion 46 on the upper floor side, are driven by the belt drive device 70 driven by the first handrail sprocket 27, and then move inside the skirt guard 44, emerging from the front skirt guard 42 from the inlet portion 48 on the lower floor side. The handrail belts 38 move in sync with the steps 30 as the first handrail sprocket 27 rotates together with the step sprocket 24. The belt drive device 70 will be explained in detail later.

[0015] At the upper floor entrance, an upper floor boarding / alighting plate 32 is provided horizontally on the ceiling surface of the machine room 14. At the lower floor entrance, a lower floor boarding / alighting plate 34 is provided horizontally on the ceiling surface of the machine room 16. A comb-tooth shaped comb 60 is provided at the tip of the upper floor boarding / alighting plate 32, and the steps 30 enter onto this comb 60. In addition, a comb-tooth shaped comb 62 is also provided at the tip of the lower floor boarding / alighting plate 34. (2) Belt drive device 70 Next, the belt drive device 70 will be described with reference to Figures 1 and 2. The belt drive device 70 is provided corresponding to each of the pair of left and right handrail belts 38, and the following will describe the belt drive device 70 on the left side as seen from the lower floor, as shown in Figure 1. In this case, the right side of the belt drive device 70 is the step 30 side. If the step 30 is rising, the handrail belt 38 inside the skirt guard 44 runs horizontally from right to left in Figure 2. The right belt drive device 70 has a symmetrical structure to the left belt drive device 70.

[0016] As shown in Fig. 1, the belt drive device 70 is provided inside the skirt guard 44 and on the upper part of the truss 12. As shown in Fig. 2, a base plate 78 is attached to the upper left part of the truss 12 on the upper surface of the truss 12 in the vertical direction.

[0017] As shown in the figure, four belt drive rollers 72 are arranged in a horizontal row (in a row in the front-to-back direction) on the upper part of the base plate 78 so as to be freely rotatable. The handrail belt 38, which is upside down, runs underneath them.

[0018] Below the four belt drive rollers 72, four belt driven rollers 74 are arranged rotatably, sandwiching the handrail belt 38, as shown in Figure 2. The belt drive rollers 72 and the belt driven rollers 74 form upper and lower pairs and hold the handrail belt 38 in between.

[0019] As shown in Figure 2, second handrail sprockets 76 are mounted coaxially on each of the four belt drive rollers 72 and are aligned horizontally on a base plate 78. An auxiliary handrail sprocket 80 is rotatably mounted on the base plate 78 between the second and third second handrail sprockets 76 from the front.

[0020] A guide handrail sprocket 82 is rotatably disposed between the first handrail sprocket 27 and the second handrail sprocket 76, as shown in FIG.

[0021] An endless second handrail chain 84 is suspended around the first handrail sprocket 27, the guide handrail sprocket 82, the upper parts of the first and second second handrail sprockets 76, the lower part of the auxiliary handrail sprocket 80, and the upper parts of the third and fourth second handrail sprockets 76. (3) Structure for moving the steps 30 and the handrail belt 38 Next, the structure for moving the steps 30 and the handrail belt 38 will be described.

[0022] 1 and 2, a drive sprocket 64 and a drive intermediate sprocket 65 are coaxially mounted on a rotation shaft 86 of a pair of left and right step sprockets 24, 24 that move the steps 30. An endless drive chain 22 is provided between the drive sprocket 64 and the output sprocket 19. This drive chain 22 is a double chain with two rows of chains lined up.

[0023] As shown in Figure 2, a driven intermediate sprocket 66 is coaxially mounted on the rotating shaft 88 of the pair of left and right first handrail sprockets 27. An endless first handrail chain 68 is stretched between the drive intermediate sprocket 65 mounted on the step sprocket 24 and the driven intermediate sprocket 66. As a result, when the step sprocket 24 rotates, the first handrail chain 68 also rotates in sync.

[0024] As described above, the endless second handrail chain 84 is stretched over the first handrail sprocket 27 coaxially with the driven intermediate sprocket 66 around which the first handrail chain 68 is stretched.

[0025] 2, when the output sprocket 19 rotates, the step sprocket 24 rotates via the drive chain 22, and the steps 30 move. Furthermore, when the step sprocket 24 rotates, the first handrail sprocket 27 rotates in sync via the first handrail chain 68, which moves the second handrail chain 84, and rotates the four second handrail sprockets 76 and the auxiliary handrail sprocket 80. When the four second handrail sprockets 76 rotate, the four belt drive rollers 72 also rotate, and the handrail belt 38 moves. (4) Fueling device 100 Next, an oiling device 100 that supplies lubricating oil (hereinafter simply referred to as "oil") to the drive chain 22, the step chain 28, the first handrail chain 68, and the second handrail chain 84 will be described.

[0026] As shown in Fig. 2, a tank 102 for storing oil is fixed to the truss 12 that constitutes the ceiling of the machine room 14 on the upper floor. In this position, the tank 102 appears when the boarding and disembarking plate 32 is lifted, making it easy to replenish the oil. As shown in Fig. 3, the tank 102 is provided with a pump 112 for pumping the oil in the tank 102, and also with a water level gauge 114, which is a sensor for measuring the remaining amount of oil in the tank 102.

[0027] As shown in Fig. 2, two first nozzles 104, 104 are provided above each of the pair of left and right step chains 28, 28. As shown in Fig. 4(a), when oil is dripped from the two first nozzles 104, 104, it falls on both the left and right sides of the step chain 28 below.

[0028] 2 and 3, two second nozzles 106, 106 are provided above the drive chain 22. As shown in Fig. 4(b), oil from the first second nozzle 106 falls on the left side of the double drive chain 22, and oil from the second second nozzle 106 falls on the center part of the drive chain 22 in the left-right direction.

[0029] As shown in Fig. 2, one third nozzle 108 is provided above each of the pair of left and right first handrail chains 68. As shown in Fig. 4(c), oil dripped from the third nozzle 108 falls on one side of the first handrail chain 68.

[0030] As shown in Fig. 2, one third nozzle 110 is provided above each of the pair of left and right second handrail chains 84. As shown in Fig. 4(c), oil dripped from the third nozzle 110 falls on one side of the second handrail chain 84.

[0031] Next, the piping structure through which the oil flows will be described with reference to FIG.

[0032] A connecting pipe 116 extends from the pump 112 and is connected to the inlet of a first distributor 118 that distributes oil.

[0033] The first distributor 118 is a junction that distributes oil into six portions, and a connecting pipe 120 that leads to the inlet of a second distributor 122 is connected to the first outlet.

[0034] The second and third outlets are connected to connecting pipes 128, 128 leading to two second nozzles 106, 106 that supply oil to the drive chain 22, respectively.

[0035] The fourth and fifth outlets are connected to connecting pipes 132, 132 leading to the two first nozzles 104, 104 that supply oil to the left step chain 28, respectively.

[0036] A connecting pipe 134 leading to the inlet of a third distributor 136 is connected to the sixth outlet.

[0037] The second distributor 122 is a junction that distributes oil in two, and a first outlet is connected to a connecting pipe 126 that leads to the third nozzle 108 that supplies oil to the first handrail chain 68 on the left side.

[0038] A connecting pipe 124 leading to a third nozzle 110 that supplies oil to the second handrail chain 84 on the left side is connected to the second outlet.

[0039] The third distributor 136 is a junction that distributes oil into three, and the first and second outlets are respectively connected to connection pipes 142, 142 which lead to the first nozzles 104, 104 that supply oil to the right-side step chain.

[0040] A connecting pipe 138 leading to the inlet of a fourth distributor 140 is connected to the third outlet.

[0041] The fourth distributor 140 is a junction that distributes oil in two, and a first outlet is connected to a connecting pipe 144 that leads to the third nozzle 108 that supplies oil to the first handrail chain 68 on the right side.

[0042] A connecting pipe 146 leading to a third nozzle 110 that supplies oil to the second handrail chain 84 on the right side is connected to the second outlet.

[0043] With the above piping structure, as shown in FIG. 3, the oil stored in the tank 102 is sent by the pump 112 to the pair of left and right first nozzles 104, 104, the second nozzles 106, 106, and the pair of left and right third nozzles 108 and 110, and is supplied to the pair of left and right step chains 28, 28, the double drive chain 22, the pair of left and right first handrail chains 68, 68, and the pair of left and right second handrail chains 84, 84.

[0044] The remaining amount of oil stored in the tank 102 can be measured by a water level gauge 114. (5) Electrical configuration of escalator 10 Next, the electrical configuration of the escalator 10 will be described with reference to the block diagram of FIG.

[0045] The control device 50 inside the machine room 14 on the upper floor is formed by a computer or the like, and is connected to a drive circuit 92. The motor 20 and electromagnetic brake 23 are connected to this drive circuit 92, and the operation / stop, moving speed, and moving direction of the steps 30 can be controlled by the control from the control device 50.

[0046] In addition, the pump 112 and water level gauge 114 of the fuel supply device 100 are connected to the control device 50.

[0047] Furthermore, a communication device 90 for communicating with the outside is connected to the control device 50. This communication device 90 is connected to a monitoring device 200 in a maintenance center that maintains and manages the escalator 10 via a public commercial line, and is also connected to a server (such as a cloud server) 202 that is located outside the escalator 10. The server 202 can communicate with a mobile terminal 204 owned by a maintenance worker, and can also obtain information necessary for managing the escalator 10, such as weather information.

[0048] The control device 50 can drive the pump 112 of the oil supply device 100 based on an oil supply signal from the monitoring device 200 or the server 202, drip oil into each chain using the first nozzle 104 to the third nozzle 110, and can adjust the amount of oil dripped at one time and the drip intervals. In addition, the control device 50 can transmit the remaining amount from the water level gauge 114, which measures the oil level in the tank 102, to the monitoring device 200 or the server 202 via the communication device 90. (6) A method for controlling the fuel supply management system of the escalator 10 Next, a control method for the fuel supply management system including the control device 50 in the escalator 10, the fuel supply device 100, the monitoring device 200, the server 202, and the mobile terminal 204 of the maintenance staff will be described.

[0049] In the first control method, the control device 50 receives a fuel supply signal from the monitoring device 200 or the server 202 via the communication device 90, and pumps oil from the pump 112 of the fuel supply device 100 based on this fuel supply signal. In this case, the fuel supply signal includes the amount of dripping at one time (reference drip amount, for example, 1 milliliter) that is preset for the drive chain 22, the step chain 28, the first handrail chain 68, and the second handrail chain 84, and the drip interval (for example, once a month), and dripping is performed based on this.

[0050] In the second control method, the control device 50 measures the remaining amount of oil in the tank 102 with the water level gauge 114, and periodically transmits the remaining amount to the monitoring device 200 and the server 202 via the communication device 90, and the server 202 transfers the remaining amount to the mobile terminal 204 owned by the maintenance staff. When the remaining amount of oil in the tank 102 falls below the reference remaining amount, the control device 50 transmits a low remaining amount signal to the monitoring device 200 and the server 202. When the low remaining amount signal is input, the server 202 issues a warning to the mobile terminal 204 owned by the maintenance staff. As a modification of this, the control device 50 may transmit a low remaining amount signal and the remaining amount to the monitoring device 200 and the server 202, and when the low remaining amount signal is input, the server 202 may issue a warning to the mobile terminal 204 owned by the maintenance staff and transmit the remaining amount.

[0051] In the third control method, when the escalator 10 is installed outdoors, for example, the server 202 constantly receives weather information and constantly obtains weather information at the installation location. Based on the weather information, after it rains at that location, the server 202 transmits a lubrication signal to the control device 50 to drip more oil than the preset reference drip amount. Based on this lubrication signal, the lubrication device 100 drips more oil than the reference drip amount to the drive chain 22, the step chain 28, the first handrail chain 68, and the second handrail chain 84, respectively. Note that this control is performed immediately after the rain stops, regardless of the drip interval set. The reason for increasing the drip amount to more than the reference drip amount is that when the escalator 10 is installed outdoors, the oil adhering to the drive chain 22, the step chain 28, the first handrail chain 68, and the second handrail chain 84 is washed away by rainwater, causing elongation due to wear of each chain, and the frequency of adjustment / replacement of the chain increases. It is also possible to prevent abnormal noises and the like caused by insufficient oil lubrication. (7) Effects According to this embodiment, the amount of oil remaining in the tank 102 is measured by the water level gauge 114 and transmitted to the monitoring device 200 and the server 202, allowing maintenance personnel to check the amount of oil remaining even in a remote location.

[0052] Furthermore, when the remaining amount of oil in the tank 102 falls below a reference remaining amount, a warning or a warning and the remaining amount is sent to the mobile terminal 204 of the maintenance personnel, so that oil can be immediately replenished.

[0053] Furthermore, if the escalator 10 is installed outdoors, even if it rains and the oil in each chain is washed away, the oil dripping amount is greater than the standard dripping amount, so the chains will not become insufficiently lubricated.

[0054] Next, a modification of the above embodiment will be described.

[0055] In the above embodiment, the pump 112 of the tank 102 and each nozzle are connected via a plurality of distributors, but this is not limiting and a single distributor may be used to distribute all of the fluid to each nozzle.

[0056] In the above embodiment, the fuel supply management system is connected to the server 202, but the present invention is not limited to this and may be connected to a DX controller to control the fuel supply management system.

[0057] In the above embodiment, the drip amount is changed based on the information of rainfall, but the drip amount and drip interval may be changed based on temperature and humidity. For example, if the air temperature continues to be higher than the set temperature for several days, the drip amount may be increased and the drip interval may be shortened. Even if the escalator 10 is installed indoors, if the business hours of the building are extended, the drip amount may be increased according to the extended hours. This is because, when the business hours are extended, the usage time of the escalator 10 also extends, and the amount of oil consumed increases.

[0058] In the above embodiment, the monitoring device 200 communicates directly with the communication device 90, but communication may alternatively be via the server 202.

[0059] In the above embodiment, the invention has been described as being applied to the escalator 10, but it may instead be applied to a moving walkway. Note that on a moving walkway, steps are called "steps".

[0060] Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.
