Abstract

<P>PROBLEM TO BE SOLVED: To provide a passenger conveyor capable of detecting peeling-off in an end part of a joint in the longitudinal direction of a film stuck to a surface of a handrail of the passenger conveyor. <P>SOLUTION: In this passenger conveyor provided with the long film 7 stuck to the surface in the longitudinal direction of the handrail 6 with a joint end part 7D and an abnormality detection device 14 provided in an inlet of the handrail 6 to detect abnormal external force and stop travel of the handrail 6, the abnormality detection device 14 operates when the joint end part 7D is peeled off and is suspended to stop the handrail 6. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to passenger conveyors such as escalators and moving walkways, and more particularly to handrails thereof.

  Conventionally, the structure which sticks a elongate film to the handrail of a passenger conveyor and uses it as an advertising medium has already been proposed, for example, as disclosed in Patent Document 1.

  The handrail of the passenger conveyor described in Patent Document 1 is such that a printed film of an advertisement is pasted in the longitudinal direction of the surface of the handrail body.

JP 2003-212468 A

  In the film pasting configuration of the handrail described in the above-mentioned Patent Document 1, there is no mention of a measure for detecting peeling of the pasting film from the handrail and preventing the expansion of trouble.

  However, the handrail that repeatedly bends in the reciprocating path of the passenger conveyor has been problematic in that it peels off from the longitudinal seam end of the film adhered and fixed to the surface.

  An object of the present invention is to provide a passenger conveyor configured to detect peeling at a longitudinal seam end of a film affixed to a handrail.

  In order to achieve the above-described object, the present invention is configured to stop the movement of the handrail by operating the abnormality detection device provided at the entrance of the handrail when the joint end of the handrail is peeled and hangs down. It is.

  Normally, the handrail of a passenger conveyor repeatedly bends into a semicircle, a 1/6 circle, and a small circle on the forward and return paths, so when the film is bonded and fixed to the handrail, it begins to peel off from the seam and expands Although this will cause danger to passengers and damage to equipment, this peeling phenomenon can be detected by the abnormality detection device.

  ADVANTAGE OF THE INVENTION According to this invention, when the joint edge part of the film affixed on the handrail peels and hangs down, the passenger conveyor which can prevent expansion of damage can be obtained by stopping a movement of a handrail etc. can be obtained.

  Hereinafter, an embodiment of a passenger conveyor according to the present invention will be described based on an escalator shown in FIGS.

  In general, the escalator 1 includes a main frame 4 that is supported across the upper floor 2 and the lower floor 3, a number of steps 5 that are connected endlessly and reciprocate between the forward path and the return path, and are synchronized with the step 5. A handrail 6 that moves and has a substantially C-shaped cross section with a flat portion 6A and semicircular portions 6B on both edges connected to the flat portion 6A, and the flat portion 6A (semicircular portion) along the longitudinal direction of the handrail 6 6B), a long film 7 that is bonded and fixed (bonding portion 7A) is provided. In this case, the film 7 is affixed to the entire length of the handrail 6 and, at the end portions 7B in the longitudinal direction, one seam end portion 7C which is adhesively fixed to the handrail 6 as shown in FIG. The other seam end portion 7D overlapping the end portion 7C is bonded and fixed (bonded portion 7E). The handrail 6 is frictionally driven by the power transmitted from the drive wheel 9 to the drive roller 11 and the like via the chain 10, and is constituted by a guide roller 12 on the return path and a rail 13 on the forward path. It is a mechanism to move according to. Further, at the entrance part where the handrail 6 enters the machine inside the balustrade 13 as indicated by the arrow Y in FIG. An abnormality detection device 14 including an electric switch 14A for stopping movement and a protector 14B is provided.

  Here, when the film 7 peels off at the end portions 7B and the joint end portion 7D hangs down, as shown in FIG. 4, the joint end portion 7D that has entered the abnormality detection device 14 in the direction of the arrow Y becomes an electric switch. The movement of the handrail 6 is stopped by operating 14A. For this reason, it is possible to prevent danger to passengers and damage to equipment due to peeling trouble of the film 7.

  As described above, according to the present embodiment, the film 7 affixed to the handrail 6 detects that the end portions 7B have been peeled off and stops the movement of the handrail 6 to the human body and equipment. The adverse effects of can be eliminated.

  In addition, although the said embodiment demonstrated the escalator as an example as a passenger conveyor, it can be applied also to the electric road which does not have a level | step difference in adjacent steps.

1 is an overall side view showing an embodiment of a passenger conveyor according to the present invention. Sectional drawing which expanded the principal part of FIG. Sectional drawing which follows the AA line of FIG. Sectional drawing equivalent to FIG. 2 explaining the effect | action of this invention.
