Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a gear drive elevator.

[0002]

2. Description of the Related Art In a conventional elevator, a cargo is suspended in a passage by a cable, and the cable is hoisted and lowered by a winch to elevate and lower the cargo.

Therefore, in the conventional elevator, one cargo moves up and down one passage, so that the transportation capacity is limited, and therefore the waiting time of the passenger is long. In addition, JP-A-5
Although the technology related to elevators is disclosed in Japanese Laid-Open Patent Publication No. 2-35047 and Japanese Utility Model Publication No. 47-1000, the former can improve the carrying function by horizontally carrying the cargo bed on the uppermost floor and the lowermost floor to expand the carrying direction. The present invention relates to a horizontal retractable long-span elevator, the latter of which is intended to hold a cage so that it does not swing, and does not move a curve along a circulation path in a safe and reliable manner.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gear drive elevator that allows a plurality of cargoes to circulate safely and reliably in an up passage and a down passage, thereby increasing transportation capacity and reducing waiting time. It is in.

[0005]

According to the gear drive elevator of the present invention, a pair of driving machines whose axes are provided in parallel with each other at diagonal corners of a cargo, and an output shaft of the driving machines are fixedly provided. A drive gear; a retaining wheel connected to the drive gear via an arm; and a pair of rails sandwiched between the retaining wheel and the drive gear, the rail having a rack that meshes with the drive gear, The rail is formed in a loop shape extending upward along the ascending passage, downward through the arcuate portion at the top and downwardly along the descending passage, and upwardly through the arcuate portion at the bottom. Vertical guide roller guides for guiding the guide rollers provided on the side surfaces of the guide rollers, the guide roller guides being erected in the ascending passage and the descending passage, and extending outward at the top and bottom thereof, respectively. It is provided.

It is preferable that the top and bottom of the rail are arcuate.

[0007]

[Description of Operation and Effects] In the gear drive elevator configured as described above, the cargo is guided by the guide roller guides and driven by the retaining wheels and the drive gear that clamp the rail having the rack to move up and down. Then, at the arcuate portion of the rail top, the driver rotates relatively to the arm due to the weight of the cargo, and the cargo is swung while maintaining the vertical position, and the up passage is switched to the down passage. Further, at the circular arc portion of the rail bottom, the cargo is switched from the downward passage to the upward passage in the same manner as described above. At that time, since the cargo is guided by the guide portions of the guide rails that spread outward in an arc shape at the top and bottom, the passage can be switched smoothly.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 4, a plurality of cargos C (only one of which is shown in each of the drawings) is housed in the up path U and the down path D, respectively. At the corners of the diagonal line of the top surface of the main body 1 of the cargo C (left front and right rear corners when the door d side is the front surface in the illustrated example),
The driving machines 2 and 2 are provided so as to face each other. The output shafts 3, 3 of the driving machines 2, 2 are arranged in parallel, and a drive gear 4 is fixedly provided at the end of each output shaft 3. One end of an arm 5 is rotatably attached to the output shaft 3, and a retaining ring 6 is rotatably provided at the other end of the arm 5. A pair of upper and lower guide rollers 7, 7 are provided on the left and right sides of the main body 1, respectively.

On the other hand, a pair of rails 10 and 10 sandwiched between the drive gear 4 and the retaining ring 6 are provided, and the rail 10 is provided with a rack 11 that meshes with the drive gear 4. These rails 10 and 10 extend upward along the ascending passage U, extend downward through the arcuate portion 10u at the top, extend downwardly along the descending passage D, and extend upward through the arcuate portion 10b at the bottom so as to circulate. That is, it is formed in a loop shape.

Further, a pair of vertical guide roller guides 12, 12 for guiding the guide rollers 7 are provided upright in the ascending path U and the descending path D, respectively. Then, on the tops and bottoms of these guides 12, 12, there are guides 12 that extend outward in an arc shape (the bottom guides are not shown).
a and 12a are provided, and adjacent guide portions 12a and 12a of the ascending passage U and the descending passage D are integrally formed. A rail cover 8 that covers the rail 10 is provided at the front of the cargo C.

Next, the operation will be described with reference to FIGS. 2, 5 and 6. When the drive gears 4, 4 are rotationally driven in the clockwise direction in FIG. 2 by the drive machines 2, 2, the cargo C is guided by the guide roller guide 12 via the guide roller 7,
It is raised by the drive gear 4 that meshes with the rack 11. When reaching the arc portion 10a at the top of the rail, the cargo C
Due to its own weight, the driving machine 2 is sequentially rotated relative to the arm 5 in the clockwise direction (90 ° at the position A), and the cargo C is swung while keeping the vertical position, and is switched to the down path D. Further, in the arcuate portion of the bottom of the rail 10,
Similarly, it is switched to the up path U.

[0013]

The present invention is configured as described above,
The following excellent effects can be achieved. (A) By combining the drive gear and the arms with the retaining wheels, a plurality of cargoes can be circulated in the ascending and descending passages to increase the transportation capacity and reduce the waiting time. (B) Therefore, reduce the number of elevators installed,
Installation space can be saved. (C) A safe and reliable circulation operation can be performed.

Therefore, it is possible to reduce the number of elevators installed and save the installation space.
