Automatic conveyor device

An automatic conveyor device, comprising:

• an entrance platform footboard, an exit platform footboard, and a series of steps running in a loop between the entrance platform footboard and the exit platform footboard;
• a first comb plate and a second comb plate respectively connected to the entrance platform footboard and the exit platform footboard through a comb support plate;
• and
• a first warning device disposed in the vicinity of the entrance platform footboard or the exit platform footboard, the first warning device comprising a display device disposed on a handrail baffle on one side of the first comb plate or the second comb plate, where when the first warning device is activated, the display device plays an animation consisting of at least three frames in a loop, the animation displaying an action of a foot stepping across the comb plate.

An automatic conveyor device, comprising:

• an entrance platform footboard, an exit platform footboard, and a series of steps running in a loop between the entrance platform footboard and the exit platform footboard;
• a first comb plate and a second comb plate respectively connected to the entrance platform footboard and the exit platform footboard through a comb support plate;
• a first warning device disposed in the vicinity of the entrance platform footboard;
• a second warning device disposed in the vicinity of the exit platform footboard;
• a first sensor that monitors passengers boarding the automatic conveyor device from the entrance platform footboard;
• and
• a controller configured to activate the first warning device based on a signal from the first sensor, and activate the second warning device after a first delay time, where the first delay time is determined based on a distance between the entrance platform footboard and the exit platform footboard and running speed of the steps;
• wherein, the first warning device and/or the second warning device comprise:
• projection devices that project light beams along a width direction in the vicinity of the first comb plate and/or the second comb plate, wherein the projection devices are disposed at handrail baffles and/or skirts on both sides, and the handrail baffles on both sides are made of transparent materials, where the projection devices, when activated, project a first longitudinal light beam and a second longitudinal light beam extending vertically along the handrail baffles on both sides, and a transverse light beam connected between the first longitudinal light beam and the second longitudinal light beam spanning the comb plate, the first longitudinal light beam, the second longitudinal light beam, and the transverse light beam jointly forming a frame-shaped light beam gate.
