Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an articulated conveying machine used for escalators, moving walkways, material conveying devices and the like.

[0002]

2. Description of the Related Art Taking an escalator as an example of a connection type transporting machine, the tread surface is kept horizontal by a guide rail and pulled by a chain, and the tread surface is turned upside down and the tread is returned unnecessarily. This is because it is a conventional type, and many types have been invented that integrally configure the reciprocating movement while keeping the tread horizontal, but due to the increase in the number of parts and technical difficulties, it was successfully industrialized. There is nothing I have done. In particular, although the drive mechanism is complicated, it is difficult to maintain the posture of the step correctly in response to the variation of the occupant.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to develop an escalator / moving sidewalk which has a simple and easy-to-manufacture structure in which the number of parts is reduced to the utmost and the posture of a step can be accurately maintained.

[0004]

[Means for Solving the Problems] A mechanism for keeping the tread horizontal by a parallel link mechanism is adopted, an extension of the axle of the wheel on which the step is placed is used as a pin for the lower link, and the link is fixed to the pin. However, it is assumed that the pin is supported by the bearing on the step side, and the link is different from the chain that acts only for pulling, and it is possible to transmit the force to pulling and pushing, so that the inside of the step row circulating endlessly A parallel link is used for driving as a transmission element of force (both pulling and pushing), and a pin provided perpendicular to the tread in the space under the moving handrail is used as a vertical pin gear on the turning part. To drive. However, a pin break point is provided at the center of the link so that it can be bent at the turning portion. Along with that, a slatch chain mechanism (invented by the present inventor) is used for driving the outside of the step row, in which the position of the step is inaccurately tolerated. The mechanism is formed by slats (steel thin pieces) capable of reciprocating left and right between teeth provided on the outer extension of the left and right chain links so that one crest and the other trough face each other. It is a mechanism that transmits power by engaging tooth bars, and has an intermediate character between gear transmission and friction transmission. To keep the slat holder parallel to the inner parallel links, the slat holder is fixed to the extension of the wheel axle parallel to the corresponding inner parallel link. Insert both ends of the slatch holder so that the distance between the axles is equal to the length of the parallel link.
The contact surface is formed as a part of a cylindrical surface having a radius of 1/2 of the length of the parallel link. After moving from the turning portion to the horizontal straight traveling portion, it is desirable to drive the steps with a friction drive vehicle so that the slatch holders contact each other with certainty.
In short, the inside is a parallel linter mechanism, and the outside is a latch
It will be driven by a chain mechanism.

[0005]

[Operation] When the pin gears are engaged with each other in the turning portion, the tread surface engaging in the engagement is kept horizontal, and the parallel link mechanism keeps the tread surface parallel, so that all tread surfaces are kept horizontal. It will be. Since the inner side is driven by the parallel link and the pin gear mechanism, and the outer side is driven by the slatch chain drive mechanism, there is no fear that the step will become unstable due to fluctuations of the occupant. It is desirable to provide a mechanism for adjusting the total length of the guide rails so that the structure can cope with errors and fluctuations in the link length.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing the entire structure excluding a moving handrail. An example of the structure of arbitrary adjacent steps 1 and 2 in the step sequence will be described. As shown in FIG. 2 (a cross-sectional front view of a horizontal straight-ahead portion), FIG. 3 (an inner side view), and FIG. 4 (an outer side view), referring to 1, a tread surface 10 is provided on the step body 11. , The inner bracket 12 and the outer bracket 13 with bolts 121 and 131, respectively.
Attached to the main body 11 together with 10, and the inner bracket 12
Two pin teeth 14 having a vertical shaft 140 are rotatably attached to the. The axle 16 is rotatably attached to the lower portions of both brackets 12 and 13 by bearings 162 and 163, respectively.
At the inner end of the axle 16, the half link 31A is keyed (may be serration or the like) so as to keep parallel to the travel rails 03 and 04, and the half link 3B is rotatably attached. At the outer end of the axle 16, a slatch holder 51 is keyed (510 is a pin at right angles to the shaft) so that the holder mandrel 510 remains parallel to the travel rails 03, 04. Half links 41A and 41B are rotatably mounted inside the inner skirt guard panel 0A of the inner bracket 12. All half-links have the same shape and size and are convenient for mass production, and the orientation and direction are different depending on the installation location. Joining pin 312 for connecting half links 31A and 32B
A parallel link 312 (link length = L) is formed by rotatably coupling with C, and half links 41A and 4 are similarly formed.
2B and the connecting pin 412C are rotatably connected to each other to form a parallel link 412 (link length = L). One wheel
It is shown by 60 and 260.

In the turning portion shown in FIG. 5, a large pin gear 80 having a vertical shaft 820 engages with the pin teeth 14, 24, ... Provided at the step. The inner corners of the steps are removed and adjacent steps contact without interference, which helps stabilize the steps during turning.

The boss 51X of the slatch holder 51 is attached to the outer end of the axle 15 (outside the skirt guard panel 0B). A holder mandrel 510 penetrates through the slat 50, and stoppers 511 and 512 that are parallel to the mandrel limit the right and left resetting angles. The slat receivers 51C and 51D for receiving the slat group are provided at both end portions of the holder mandrel 510, but both end surfaces thereof are at positions where they do not interfere with the chain, and a part of the cylindrical surface 51A, 51B having a radius L / 2 concentric with the axle center line. The cylindrical surfaces are in contact with each other so that the axle spacing is kept equal to the parallel link length L even in the transition section where the travel rail shifts from the horizontal straight travel to the inclined straight travel.

As shown in FIG. 6 (partially sectional front view), FIG. 7 (partially sectional plan view), and FIG. 8 (side view), the structure of the slat chain 6 which should be engaged with the slat 5 is that the chain pin 60 is Outer extension portions of the penetrating link plates 61, 62 are provided with ridges 61A, 62A and valleys 62B, 61B facing each other, and the slat is sequentially bitten between the ridges and valleys away from the sprocket tooth tips. Then, the tooth bar is formed by the slat, and power is transmitted from the chain to the slat. The situation is similar to the PIV drive used in continuously variable transmissions, but the fundamental difference is
In the PIV method, since the slat is pushed into the fan-shaped groove provided with the cone as the reference, it is difficult to transmit a large force because the corner of the slat hits the slope of the mountain, whereas in the present invention, the slat is inserted in the parallel grooves. Since it pushes in, it has a wide contact and can transmit a large force. At the beginning of biting (downstairs and upstairs), the push car 95 may be operated.

The V-groove friction wheel 7 is provided with V-grooves 71, 72, ... In such a manner that the steps which have come around the turning portion with their outer sides separated from each other are in close contact with the outer end at the horizontal straight-moving portion. It is important that they are pressed against each other to drive the steps to bring the slatch holders into contact with each other.

As shown in FIG. 1, the main part of the drive system of the step is a motor 9X, a reduction gear 9Y, and a large diameter gear 80 attached to a vertical shaft 820 of a bevel gear 82 meshing with a bevel gear 81 on a shaft 91. To drive. On the other hand, a bevel gear 83 of the same size as 81 meshes with the bevel gear 82 and rotates in the opposite direction to rotate its shaft 93.
Rotates in the direction opposite to the shaft 91, and the chain drive drives the slack chain sprocket 910 and 930 on the descending side and the ascending side from the shaft 91 and the shaft 93, respectively, to form intermediate sprocket 91a, 91b, 91c, 91d and 9 respectively.
It is driven through 3a, 93b, 93c and 93d. It should be noted that the movement handrail-related is omitted because it is out of the scope of the present invention.
