Description

Technical Field

[0001] The present invention relates to the field of automatic transport devices, and more particularly to a warning device for an area between a platform pedal and a step of an automatic transport device and an automatic transport device having the warning device. Background Art

[0002] Automatic transport devices such as escalators and moving walkways are often used to transport passengers between two fixed platforms. For automatic transport devices, the area between the moving parts and the stationary parts is a relatively dangerous area, such as between the circularly moving steps and the fixed platform. In the prior art, the fixed platform is generally provided with a comb plate at the intersection with the steps. The front end of the comb plate has a plurality of comb teeth, and the comb teeth cooperate with the plurality of grooves on the surface of the steps. A sensor is provided inside the comb plate. When an external object is caught and causes the comb plate to tilt, the sensor is triggered and the automatic transport device stops suddenly, which will cause danger and damage to the automatic transport device.

[0069] Figure 1 An escalator 10 is illustrated. In the ensuing description, it should become apparent that the present invention is applicable to other passenger conveyor systems, such as moving walkways. The escalator 10 generally includes a truss 12 extending between a lower landing 14 and an upper landing 16. A plurality of sequentially connected steps or pallets 18 are connected to a step chain 20 and travel through a closed loop path within the truss 12. Pairs of handrails 22 include moving handrails 24. A drive machine 26 or drive system is typically positioned in a machine space 28 below the upper landing 16; however, an additional machine space 28' may be positioned below the lower landing 14. The drive machine 26 is configured to drive the pallets 18 and / or handrails 24 via the step chain 20. The drive machine 26 operates to move the pallets 18 in a selected direction at a desired speed under normal operating conditions.

[0070] The pallet 18 makes a 180 degree change of forward direction in a turning area 19 located below the lower landing 14 and the upper landing 16. The pallet 18 is pivotally attached to the step chain 20 and follows the closed loop path of the step chain 20, running from one landing to another and back again.

[0071] The drive machine 26 includes a first drive component 32, such as a motor output sheave, connected to a drive motor 34 via a belt reduction assembly 36, which includes a second drive component 38, such as an output sheave, driven by a tensioning component 39, such as an output belt. In some embodiments, the first drive component 32 is a driving component and the second drive component 38 is a driven component.

[0072] As used herein, in various embodiments, the first drive member 32 and / or the second drive member 38 can be any type of rotating device, such as a rope, pulley, gear, wheel, sprocket, cog, pinion, etc. In various embodiments, the tension member 39 can be configured as a chain, belt, cable, belt, band, strip, or any other similar device that operatively connects two elements to provide a driving force from one element to another. For example, the tension member 39 can be any type of interconnecting member that extends between the first drive member 32 and the second drive member 38 and operatively connects the first drive member 32 and the second drive member 38. In some embodiments, as Figure 1 As shown in FIG. 1 , the first drive member 32 and the second drive member 38 may provide belt reduction. For example, the diameter of the first drive member 32 may be approximately 75 mm (2.95 inches), while the diameter of the second drive member 38 may be approximately 750 mm (29.53 inches). For example, the belt reduction allows the sheaves to be replaced to change the speed for 50 or 60 Hz mains power applications or different step speeds. However, in other embodiments, the second drive member 38 may be substantially similar to the first drive member 32.

[0073] As noted, the first drive member 32 is driven by the drive motor 34 and is thus configured to drive the tensioning member 39 and the second drive member 38. In some embodiments, the second drive member 38 may be an idler gear or similar device that is driven by the tensioning member 39 through the operative connection between the first drive member 32 and the second drive member 38. The tensioning member 39 travels around a loop set by the first drive member 32 and the second drive member 38, which may be referred to as a small loop hereinafter. The small loop is provided for driving a larger loop, which is composed of the step chain 20 and is driven by, for example, the output sheave 40. Under normal operating conditions, based on the movement speed of the first drive member 32 as driven by the drive motor 34, the tensioning member 39 and the step chain 20 move in unison.

[0074] The escalator 10 also includes a controller 115 in electronic communication with the drive motor 34. As shown, the controller 115 can be positioned in the machine space 28 of the escalator 10 and is configured to control the operation of the escalator 10. For example, the controller 115 can provide a drive signal to the drive motor 34 to control the acceleration, deceleration, stop, etc. of the pedal 18 through the step chain 20. The controller 115 can be an electronic controller including a processor and an associated memory, the memory including computer executable instructions, which, when executed by the processor, cause the processor to perform a variety of operations. The processor can be, but is not limited to, a single processor or multi-processor system of any architecture in a variety of possible architectures, including field programmable gate arrays (FPGAs), central processing units (CPUs), application specific integrated circuits (ASICs), digital signal processors (DSPs), or graphics processing units (GPUs) hardware arranged in a homogeneous or heterogeneous manner. The memory can be, but is not limited to, random access memory (RAM), read-only memory (ROM), or other electronic, optical, magnetic, or any other computer-readable medium.

[0075] Although described herein as a specific escalator drive system and specific components, this is merely exemplary, and those skilled in the art will recognize that other escalator system configurations may operate with the invention disclosed herein.

[0076] refer to Figure 2 The automatic transmission device according to an embodiment of the present invention is introduced. The automatic transmission device includes: an entrance platform pedal 161, an exit platform pedal 141 ( Figure 2Not shown, a series of steps 18 corresponding to the platform pedal at the lower platform 14) and the circulation between the entrance platform pedal 161 and the exit platform pedal 141, the first comb plate is connected to the entrance platform pedal via the comb plate support plate, and the second comb plate is connected to the exit platform pedal via the comb plate support plate. Specifically, the first comb plate 171 is connected to the entrance platform pedal 161 via the comb plate support plate 17. In this article, the area D near the comb plate 171 can be defined as an area extending the length of one step 18 forward and backward from the comb plate 171 respectively. A first warning device and an optional second warning device may be provided near the comb plates of the entrance pedal platform and the exit pedal platform, and the first warning device and the second warning device may include warning devices based on sound, light or electricity, and the first warning device and the second warning device may include a closed state and an activated state. In the closed state, the first warning device and the second warning device are closed or in a dormant state, so that basically no energy consumption is generated, and in the activated state, the first warning device and the second warning device work in various ways that will be described in detail below. The warning device according to the embodiment of the present invention actively warns passengers by changing from a closed state to an activated state. In particular, for passengers who are checking their mobile phones, this environmental change can make them aware of the dangerous area near the comb plate. In addition, a first sensor 41 can be provided to detect passengers entering the automatic transmission device from the entrance platform pedal 161. Figure 2 The steps of the automatic transmission device shown move from the entrance platform pedal 161 to the exit platform pedal 141, and the first sensor 41 can be set at the entrance platform pedal 161, for example, it can be set at the skirt board near the comb plate 171. When the passenger enters the automatic transmission device from the entrance platform pedal 161, the first sensor 41 senses the passenger and sends a signal to the controller, and the controller activates the first warning device based on the signal of the first sensor 41. In some embodiments, the first sensor 41 can be a light-based sensor, such as an infrared sensor, etc. In alternative embodiments, the sensor 41 can also be set as a radar sensor or a camera device, etc.

[0077] like Figure 3 As shown, in some embodiments of the present invention, the controller is configured to detect the presence of a sensor at T 1 The signal sent at the time point activates the first warning device, that is, the controller sends a first control signal S 1 to the first warning device, that is, the first warning device at the entrance step platform in this embodiment, to activate the first warning device, and after a first delay time T 2 Then the second warning device is activated, that is, a second control signal S is sent. 2 The second warning device at the exit step platform is activated. The first delay time T 2The first delay time T may be determined based on the distance between the entrance platform pedal 161 and the exit platform pedal 141 and the operating speed of the step 18. 2 It can also be changed based on the passenger's actions on the steps 18, such as whether the passenger is standing or walking. More specifically, during operation, when the passenger lands on the steps with the entrance platform step 161, the first warning device near the entrance step platform is activated, and the time when the passenger will arrive near the exit step platform can be estimated, and the second warning device near the exit step platform is activated based on the estimated time.

[0078] Although the first sensor and the first delay time are used in the above embodiment, in an alternative embodiment, a second sensor may be arranged near the exit step platform, and the second sensor monitors the passengers who are about to leave the automatic transmission device from the exit step platform. At this time, the controller may activate the second warning device based on the second sensor. It should be understood that in general, the running direction of the automatic transmission device can be adjusted. For example, when the automatic transmission device runs in the reverse direction, i.e., upward, the entrance platform step 161 and the exit platform step 141 are interchanged (for example, Figure 4 , the entrance platform pedal 161 is set at the lower platform), and the automatic transmission device includes both the first sensor and the second sensor, which can better cope with the automatic transmission device running in different directions. Figure 3 As shown, in some embodiments, the first control signal S1 and the second control signal S2 can be pulse signals, that is, only the first warning device and the second warning device are activated for a second delay time T3, for example, 30 seconds to 1 minute, etc., that is, if no further control signal is received, the first warning device and the second warning device will return to the closed state after the second delay time T3, thereby saving energy consumption.

[0079] Continue to refer Figure 4, which shows a warning device according to an embodiment. In some embodiments, the first warning device and / or the second warning device includes a display device 5 disposed at the handrail guard 25. Although in the illustrated embodiment, the display device 5 is only disposed on one side of the handrail guard 25, in an alternative embodiment, the display device 5 may be disposed on both sides of the handrail guard 25. The display device 5 repeatedly plays an animation including at least three frames, and the animation shows the passenger's feet crossing the comb plate. For example, as shown in the figure, in the first frame 51 of the animation, the foot is on the ground and in front of the comb plate 171; in the second frame 52 of the animation, the foot is lifted and substantially aligned with the comb plate 171; and in the third frame 53 of the animation, the foot is on the ground and behind the comb plate 171, and then the above animation is repeated, thereby prompting the passenger to lift his foot and cross near the comb plate. The animation device provides an interesting elevator riding experience while attracting the attention of passengers, and under the stimulation of the animation, the passenger tends to imitate the animation action and cross the comb plate 171. The display device 5 may be a simple display device based on an LED light or may be a liquid crystal display device. The display device 5 may be completely turned off or remain still in the first frame state when no signal is received. In some embodiments, the positions of the first frame 51, the second frame 52, and the third frame 53 on the display device 5 correspond to the position where the passenger correctly crosses the comb plate to provide correct instructions. In some embodiments, the display device 5 may play an animation including more frames. Although in the illustrated embodiment, the display device 5 is located near the entrance platform step, a similar display device 5 may be provided near the exit platform.

[0080] Continue to refer Figure 5 , which shows a warning device according to another embodiment. The first warning device and / or the second warning device may also include a light bar 56 with warning text located on the comb plate or comb plate support plate of the entrance platform pedal or the exit platform pedal, or light bars 57, 58 with warning text on the handrail baffle 25 on both sides near the comb plate or embedded in the handrail baffle 25 (for example, when the handrail baffle is transparent glass). The warning text includes, for example, "Do not stay", "Please cross", etc. These light bars 56, 57, 58 are lit or flashed after being activated, so that the warning text appears more clearly, thereby prompting passengers to pay attention to the area.

[0081] Continue to refer Figure 6, which shows a warning device according to another embodiment. In this embodiment, the first warning device and / or the second warning device includes an embedded display screen 881 embedded near the comb plate of the entrance platform pedal or the exit platform pedal, such as a comb plate support plate or a platform pedal, and a surrounding light strip 871 is arranged around the embedded display screen 881. In some embodiments, the embedded display screen 88 and the surrounding light strip 87 can also be directly arranged at the entrance platform pedal 161 or the exit platform pedal 141. When the first warning device and / or the second warning device is activated, the embedded display screen 88, 881 is illuminated and displays warning text, and the surrounding light strips 87, 871 are illuminated or flashing. In addition, in some embodiments, the first warning device and / or the second warning device includes a sound prompt device 86, such as a speaker, and when the first warning device and / or the second warning device is activated, the sound prompt device broadcasts the prompt information. In addition, in Figure 6 In the illustrated embodiment, the steps also move from the entrance platform pedal 161 to the exit platform pedal 141, but a second sensor 441, 442 is arranged near the exit platform pedal 141. In this embodiment, the second warning device is activated by the signal of the second sensor instead of based on the first delay time, so that the activation time of the second warning device can be more accurate and will not be affected by unexpected events. In this embodiment, the second sensor 441, 442 can be an infrared light-based sensor, which includes a light transmitter 441 and a light receiver 442. When the light receiver 442 is blocked, the second sensor sends a signal to the controller, and thereby activates the second warning device, including the embedded display screen 88, 881, the surrounding light strip 87, 871 and / or the sound prompt device 86. In some embodiments, the second sensors 441, 442 are arranged on the elevator skirt or handrail guard 25 on both sides.
