Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to an articulated conveyor machine with an integrated reciprocating path, and is applicable to pedestrian bridges, outdoor workshops, terminals, escalators, moving walkways in buildings, etc. Suitable for use in journal entry devices, etc.

(Conventional technology) Taking a conventional escalator as an example, two special guide rails are used as a mechanism to keep the step surface horizontal, and the return trip is structured so that the user returns on the back side of the escalator in a handstand position. Therefore, in order to perform the round trip at the same time, separate equipment must be used. There is no such thing as continuous running back and forth using a single piece of equipment. The same goes for moving walkways.

(Problems to be Solved by the Invention) The problem lies in the mechanism that circulates in a continuous path through ascending, descending, and horizontal movement while keeping the step base surface horizontal, and the step platform drive mechanism.

(Means for solving the problem) In order to keep the step reference plane horizontal during the entire reciprocating process, use step platform guide rails that are continuous and have different shapes on the outbound and return trips, and connect the step platforms. The main means of solving the problem is to make the element bendable at the turning part (the part that connects the outgoing and incoming passes) and to select a drive mechanism suitable for that case.

(Operations and Examples) As shown in Fig. 1.2, the outward horizontal straight running section of the downstairs (
A), straight-line ascending section (B), outbound horizontal straight-travel section on the floor (
C), Turning section on the upper floor (D), Return horizontal straight running section on the upper floor (E), Straight descending section (F), Return horizontal straight running section on the lower floor (G), Turning section on the lower floor (H) A basic example will be explained of an escalator that returns to the outward horizontal straight running section (A) on the lower floor.

As shown in Figure 3, the basic guide rail Of (inside), 02 (outside, not shown) connects the downstairs and the upstairs in a circular manner.
By, the basic support pin l (inside) of the step stand l00
．． 2 (outside, not shown) and vi4=IIP).

The locus of the center of the guide rail for each part is determined as follows.

Set the center of basic support pin 1 to 01 auxiliary support pin 3I Let the angle formed with the chip surface lO be d, and the stroke inclination angle be.

The distance h between the trajectory of 0 and the trajectory of the object is . In the straight ascending section B (Fig. 4), h = rsin (ot+/), in the straight descending section F (Fig. 5), h = rsin (0c-/), and in the horizontal traveling section (Fig. 6.7) h = r sin , and at the boundary between the horizontal running part and the inclined running part (ascending, descending), the locus of O has a shape according to the transition curve given as the locus of O,. For example, if part B moves to part C, as shown in Figure 8, if the locus of O, is expressed in orthogonal coordinates (x, y), then the locus (X, Y) of 0 is X. = x + rcosoc. Y = Y
rBin61 te table sa h le Oo. ．． o. The same applies to

For reasons of aesthetics and safety, the support bin must be positioned so that the guide rail is not exposed on each stroke.

The mechanical elements that connect the step platform are not particularly limited, but
It must be of a structure that allows bending around the horizontal axis at the boundary between strokes with different inclinations, and around the vertical axis at the turn. Wire ropes, chains connected with universal joints, etc. are suitable for this condition, but as shown in Fig. 9(a) and (b),
One of the preferred link mechanisms is a link mechanism that combines a bifurcated link 8 with a hole at one end and a monolithic link 8 with a hole twisted at the other end by 90 degrees. The bifurcated portion of the link 82 and the single tongue portion of the link 8l of this structure are attached to the horizontal pin 80 perpendicular to the direction, and the single tongue portion of the link 82 and the bifurcated portion of the link 83 attached to the adjacent step stand 200 are connected. are refractably coupled with a pin 812.

With the link mechanism as described above: 'Pin 80 (horizontal axis)
We now have a connecting element that is bendable around the bin 812 (the vertical axis). However, in order to prevent this link mechanism from interfering with the support pin, it is provided on the other side as shown in FIG. 10 (showing the case where it is in the horizontally straight traveling section), and the link mechanism is provided inside the side plate. This is also advantageous in that the driving force is closer to the center of the step platform.

When a wire rope is used as a connecting element, it is best to attach flexible teeth to the wire lobe and drive it with a gear, and when a chain connected with a universal joint is used, it is best to drive it with a matching chain gear. good. When the above-mentioned link mechanism is used, in order to push the adjacent step platforms 100 and 200 against each other in the inclined traveling portions B and F, as shown in FIG. 11 (only the case of Bl is shown), the upper Protrusions 121, 221 and lower protrusions 122, 22
2 is provided so that one two-part protrusion and the lower protrusion of the other party maintain contact in both cases of ascending and descending.

In the horizontal straight running sections A, C, E, and G, adjacent step plates l3 and 23 are brought into contact with each other. Turning part D. In order to prevent the inner corners of adjacent step plates 13 and 23 from interfering with each other, the inner corners of the adjacent step plates 13. The diagonal parts 132 and 231 come into contact so that the step stand assumes a correct posture.

As shown in FIGS. 3 and 13, each step plate (represented by 13) is provided with two bottle-shaped teeth 61 and 62 that mesh with the step platform driving pin gear 5 provided in the turning section H. Here, r is the pitch circle radius of the pin gear 5, and 戊 is the angular pitch of the teeth. When there are no passengers, the weight of the step platform row is balanced between the rising and descending parts, and it can be driven with a small amount of power, and even if there are passengers, the difference in passenger weight between the rising and descending sides is Although a proportionate amount of extra power is required, its magnitude is relatively small. As shown in FIG. 12, the gear shaft 50 is driven by a bevel gear device 7 via an electric motor 6 and a reduction gear 6l.

As the movable handrail, it is preferable to use a handrail unit 9 connected by a universal joint as shown in Fig. 1 4.1 5.1 6. The figures show a plan view and a cross-sectional front view, respectively, where 90 is the handrail unit body, 9l is a T-shaped piece (in place of a cross piece), 92 is the vertical axis of the T-shaped piece, and the end face 9
21,922 suppresses the horizontal movement of the T-shaped piece 9l. 93
94 is a concave spherical surface, 96.97 is a pin-shaped tooth. A continuous moving handrail for the entire stroke is provided only on the inside of the inner rail, and a moving handrail guide rail 98 provided in parallel inside the inner guide rail for the step platform guides the guide roller 95 and causes it to travel. As shown in FIG. 17, in order to drive the handrail unit 9 (the outline of which is indicated by a thin line), a pin gear 99 provided at the turning portion H is engaged with pin-shaped teeth 96 and 97. Since the pitch circle diameter of the movable handrail driving pin gear 99 is smaller than the pitch circle diameter of the step base driving pin gear 5, in order to make the movable handrail and the step base at the same speed, as shown in FIG. The speed of the shaft 990 of the handrail driving pin gear 99 is increased by a speed increasing device 991.

The number of step platforms and movable handrail units is an integer number, and dimensional errors are unavoidable, so
It is necessary to have a structure in which the overall length of each rail can be adjusted so that all step platforms or handrail units are always pressed against each other.

Since they are connected in a flexible manner, measures must be taken to prevent adjacent step platforms and moving handrail units from interfering with each other (e.g., removing parts that would cause interference).
If you take the following steps, it can be applied to curved escalators. The invention is also applicable to moving walkways and the like, especially to walkways with slopes or curves, and to baggage sorting equipment in terminals.

The vertical depth is shallower than traditional escalators.
Since it is light in weight, it can be installed on existing stairs with simple construction and minor modifications. Furthermore, if the slope is long, a rail can be installed along a landing provided in the middle, which reduces the fear of passengers.

If the stroke is long, two or more drive mechanisms may be provided for synchronized operation. Even when the L ascending stroke and descending stroke are far apart, separate electric motors may be operated synchronously. A skirt I7 with a retractable hem is provided at the front and rear of each step platform, but a gap is created on the outer circumferential side in the case of Kairo. However, since that part is hidden under the floor, there are no aesthetic or safety issues.

Note that it is not prohibited to use different types of drive mechanisms together in order to make the drive more reliable or powerful.

(Effects of the Invention) According to the present invention, it is possible to obtain an articulated conveyance machine that has a simple and lightweight structure and runs in the form of a single system throughout the entire journey including L ascending and descending, and it is possible to provide an articulated conveyance machine that has a simple and lightweight structure. The modification will allow for the installation of a round-trip escalator. Stairs in public facilities such as stations are not only tiring for elderly and sick people to climb, but also pose a great risk of falling when descending.
With the present invention, these efforts and risks are eliminated altogether.

Furthermore, if applied to pedestrian bridges, it would be possible to significantly increase the usage rate of pedestrian bridges, which are often avoided.

Furthermore, since it can be applied to curved escalators, restrictions on where it can be applied are relaxed, and the use of graceful curves has the effect of improving the scenery of buildings and tourist facilities.
Being able to set tracks can be used to improve the efficiency of baggage sorting rooms at terminals, and can also be applied to moving walkways with slopes and curves, expanding the range of applications.
