Abstract

A device for detecting operation direction of a passenger conveyor. The center (p) of a rotating body (81) of an operation direction detection device (8) and the center (P) of rotation of an output shaft (rotating shaft)(4a) connected to a rotating machine (4) are separated (delta P) from each other. This causes the rotating body (81) to eccentrically rotate and a detection piece (821) oscillates in the direction corresponding to the direction of the rotation. The oscillation enables detection of the rotation direction of the rotating machine (4). An end of the detection piece (821) faces and slides on the circular outer peripheral surface of the rotating body (81). Because the outer peripheral surface has no irregularity and the end of the detection piece (821) smoothly slides along the surface while keeping in intimate contact with the surface, noise is reduced.

That is, Fig. 5 (a) is the amplification right elevation with the cooresponding main portion of Fig. 3, and Fig. 5 (b) is that B-B among Fig. 5 (a) is to cutaway view.
Shown in Fig. 5 (a) and (b), the operating direction detecting device 8 of present embodiment is identical with conventional art, and the output shaft 4a that is contained in the spinner 4 by reductor is on the S. A..Operating direction detecting device 8 comprises: the barrel-contoured swivel 81 that rotates in linkage with the rotation of spinner 4; And a top ends of detection lug 821 contacts with these swivel 81 outer peripheral face slide relative and the switch 82 that constitutes.
Shown in Fig. 5 (a) and Fig. 5 (b), in direction peripheral shape is installed and is circular swivel 81 with the axial quadrature of spinner 4 output shaft 4a.Swivel 81 is mounted to the center P deviation distance Δ P of the output shaft 4a of its center p and spinner 4.The peripheral part of the swivel 81 that contacts with detection lug 821 is synthetic resin member 81b, and deburring.
Therefore, the detection lug 821 of switch 82 is that middle mind-set arrow directions X rotates or swings freely with turning cylinder 821a shown in Fig. 5 (b).And, with p position, swivel 81 center behind the centre of gration P deviation distance Δ P of spinner 4 be positioned at centre of gration P directly over when (diagram top), the length direction of the posture of detection lug 821 becomes vertical.At this moment, the top ends of detection lug 821 (being roller 821b) is configured to the outer peripheral face butt with swivel 81.Top ends is identical with conventional art with the detection lug 821 of swivel 81 moving contacts, and its length direction receives the application of force of not shown force application apparatus with being always vertical.
Fig. 6 is the action specification figure of operating direction detecting device 8, if swivel 81 (being spinner 4) rotates to diagram arrow R direction (anticlockwise direction) from the state shown in Fig. 6 (a), then shown in Fig. 6 (b), detection lug 821 rotates, and makes limit switch 823a move (connection).
In addition, if after swivel 81 to diagram arrow R direction (anticlockwise direction) rotation, then turned back to the location status shown in Fig. 6 (a), the action of the detection lug 821 of limit switch 823a just stopped (disconnection).
Therefore, in the spinning movement of diagram arrow R direction (anticlockwise direction), limit switch 823a carries out the on-off action repeatedly because of the swing of detection lug 821, and sends this repeated signal at swivel 81.Therefore, at the signal receiver side that receives from the signal of limit switch 823a, can detect spinner 4 and rotate to anticlockwise direction (arrow R direction).
In addition, swivel 81 to diagram arrow R side in the opposite direction in the spinning movement of (clockwise direction), detection lug 821 swing on the contrary, moves so that another limit switch 823b carries out on-off repeatedly, and sends this repeated signal.Therefore, at the signal receiver side that receives from the signal of limit switch 823b, can detect spinner 4 to right-hand revolution.
Promptly, if spinner 4 moves, carry out the rising operation of escalator to arrow R direction rotation shown in Figure 6, then the bottom of detection lug 821 carry out repeatedly an a left side → central authorities → left side → central authorities → left side → ... swing, and make limit switch 823a do on-off action.Therefore, if constitute limit switch 823a, then close → open → close → open → close with a contact ... signal repeatedly transmit.
In addition, if escalator moves counter-rotating from the operation of rising to descending, then by opposite with arrow R direction shown in Figure 6 around clockwise rotation, the right side → central authorities → right side → central authorities → right side is just carried out repeatedly in the bottom of detection lug 821 ... swing make limit switch 823b do on-off action.Therefore, if constitute limit switch 823b, then open → close → open → close → open with the b contact ... signal repeatedly transmit.
So, connect airtight and slide relative smoothly along the toroidal outer peripheral face of the no concave-convex of swivel 81 end of detection lug 821, and limit switch 823a, 823b are operated.Therefore, can avoid such in the past noise to take place.
According to said structure, if operating instruction is the operation of rising, then should transmit the output on-off signal of supply from limit switch 823a, if but transmitted the output on-off signal supplied with from limit switch 823b, the direction that then can detect the service direction that the operation beginning instructs to being different from would be carried out.Therefore,, be controlled to safety device and move, operation is stopped at once for safety.
In the embodiment of above-mentioned explanation, the hand of rotation of the swaying direction of detection lug 821 and swivel 81 (spinner 4) changes accordingly.Therefore, justifying the center p of swivel 81 of shape and center P that S. A. is output shaft 4a is mounted to and departs from Δ P.But even under the center of the swivel 81 p state consistent with the center P of output shaft 4a, the swaying direction of detection lug 821 also changes exportable switching signal accordingly with the hand of rotation of swivel 81 (spinner 4).
That is, Fig. 7 to Fig. 9 is and the cutaway view of the corresponding expression of Fig. 5 (b) that Fig. 7 represents swivel 81 is done ovalisation and made the state after the installation under its center p state consistent with the center P of output shaft 4a.
In addition, Fig. 8 represents that swivel 81 makes the occasion of the shape after a part of linearity on the circumference cut, and Fig. 8 represents to make polygonal occasion.In any occasion, all be under the state that the center p of swivel 81 is consistent with the center P of output shaft 4a, to install.
So, to the shape of swivel 81 shown in Figure 9, arbitrary occasion all is that the center p of swivel 81 is consistent with the center P of output shaft 4a at Fig. 7.Under arbitrary occasion, one end of rotating detection lug 821 all with swivel 81 outer peripheral face slide relative contact and corresponding with the cyclical variation of the difference of radius from center p (P) to swivel 81 peripheries, carry out and the corresponding level and smooth swing of swivel 81 hand of rotation.But arbitrary occasion is transport direction and the cooresponding switch output signal of spinner 4 hand of rotation all.
In the above description, illustrated that contact portion swivel 81 and detection lug 821 constitutes with synthetic resin member 81b and the formation of deburring.In addition, forms by the synthetic resin member too, can further alleviate the noise generation with the roller 821b of detection lug 821 top ends of this synthetic resin member 81b slide relative and rotation.
Practicality on the industry
The operating direction detecting device of the passenger conveyors of the 1st invention, owing to depart between the pivot of the pivot of rotary body and rotating shaft, so rotary body carries out eccentric rotary. The detection lug of the rotary body outer peripheral face relative sliding of one end and this eccentric rotary, tilt accordingly with the rotation of rotary body, because the direction of rotation of its incline direction and rotary body changes accordingly, therefore, the direction of rotation that can detect circulator is the traffic direction of passenger conveyors.
In the present invention, connect airtight and relative sliding smoothly along the circular circumference face of the no concave-convex of rotary body an end of detection lug, therefore can avoid in the past such noise to take place.
