Description

Description: TECHNICAL FIELD The present invention relates to a vertical continuous transportation device.

(Prior Art) Conventionally, an endless loop-shaped escalator is spirally arranged around a vertical axis, and the spiral escalator is rotationally driven by a driving device, so that a tread provided on the spiral escalator. As a method for ascending and transporting a person, those disclosed in JP-A-49-63176 and JP-A-58-197179 are known.

This method is different from the conventional one that is arranged in an inclined shape,
This is advantageous in that the installation floor area of the escalator can be reduced. This effect is more pronounced as the head is higher.

However, in these systems, the loop-shaped escalator is transported on a tread only by one way, for example, from the lower position to the upper position, and after the transport is completed, the loop-shaped escalator is moved from the upper position to the lower position. In the process of returning to the above, there is a problem in that the person is not transported by the tread plate, and therefore, in one circulation rotation of the loop escalator, the return path is rotated regardless of the transportation of the person.

(Problems to be solved by the invention) In view of such a situation, the present invention solves the above-mentioned problems existing in the conventional apparatus of this type, thereby reducing the installation area and significantly reducing the amount of transportation. But to provide a continuous transportation device.

(Means for Solving the Problems) A plurality of spiral escalators each having a predetermined pitch and a predetermined radius are arranged around each of the vertical axes separated by a predetermined distance in the horizontal direction. Both ends of the spiral escalator are connected via a connecting member. An elevator that moves up and down along the vertical space is arranged in a vertical space inside the spiral escalator, and the combined use of the spiral escalator and the elevator further improves the amount of personnel or luggage transported.

(Operation) Both ends of the spiral escalator arranged around one vertical axis and the spiral escalator arranged around the other vertical axis that are paired with the spiral escalator are connected by a connecting member, and the driving device is driven. I do. Thereby, one spiral escalator is used as an ascending escalator and the other spiral escalator is used as a descending escalator.
The transport function is performed through the entire circulation and rotation of the loop escalator including one spiral escalator, one continuous member, another spiral escalator, and another connecting member. As a result, the amount of lifting and lowering transportation is significantly improved.

A known elevator that moves up and down along the vertical space between the one spiral escalator and the other spiral escalator is provided. The elevator carries luggage or the like of a physically handicapped person or an occupant. As a result, the transport amount of the occupants and the luggage is significantly improved.

(Example) The present invention will be described with reference to an example shown in Fig. 1 to Fig. 4 (b).

9 and 10 are arranged at predetermined intervals in the horizontal direction,
For example, on the vertical axis of the vertical cylinders 91 and 101, spiral escalators 1 and 2 are arranged in a stacked manner around the vertical axis 9, and spiral escalators 11 are arranged around the vertical axis 10.
And 12 are arranged in an overlapping manner. The spiral escalators 1 and 2 are concentrically arranged at an angle of, for example, 180 degrees. The same applies to the spiral escalators 11, 12.
In practice, the spiral escalators 1 and 2, 11 and 12 are configured to move along a known guide, not shown, as is well known. The spiral escalators 1, 11 and 2, 12 are guided by a known guide by driving a known driving device (not shown), and are spirally fed in the direction of the arrow as shown by solid and dotted lines in FIG. At predetermined positions of the spiral escalators 1, 2, 11, and 12, a known tread plate 13 is provided by a known means so as to maintain a horizontal position throughout the entire moving process. The interval between the tread of any one of the spiral escalators and the tread of the other spiral escalator immediately above it is set sufficiently larger than the height of the occupant.
The occupant's head is not touching the tread directly above. The same applies to the spiral escalators 11, 12. The upper and lower ends of the spiral escalator 1 are connected to the upper and lower ends of the spiral escalator 11 via connecting members 4 and 6. The upper and lower ends of the spiral escalator 2 are connected to the upper and lower ends of the spiral escalator 12 via connecting members 3 and 5. Treads 13 having the same shape and the same performance as the treads 13 described above are also provided at predetermined positions of the connecting members 4, 3, 6, and 5, and constitute a part of the spiral escalator. In this embodiment, the driving device includes a spiral escalator 1,
Two are provided, one for 11 and one for the spiral escalators 2, 12. On the other hand, spiral escalators 1, 2
Known elevators 7 and 8 that can be moved up and down along the vertical spaces are provided in the vertical spaces in the vertical spaces 11 and 12.

In such a configuration, by driving a driving device for the spiral escalators 1 and 11 (not shown), the spiral escalators 1 and 11 move in the directions indicated by arrows.
Thereby, the spiral escalator 1 is raised and lowered, and the spiral escalator 11 is raised and lowered. As a result, the tread plate 13 used for climbing around the vertical axis 9 carries a person to the position above the vertical axis 9 and then passes through the continuous member 4 portion provided for transfer, Immediately around the vertical axis 10, it is used as a descending tread, and then the same transport is repeated via the connecting member 6. Therefore,
According to the present invention, unlike the conventional method, the spiral escalator 1, the connecting member 4, the spiral escalator 11, the connecting member 6
Stepping board throughout the process of circular rotation of the loop composed of
13 can carry out the crew transport function without rest.

When the driving device for the spiral escalators 2 and 12 is driven, the tread plate 13 used for descending around the vertical axis 9 by the same reason, after passing through the connecting member 5 portion at the transfer position, It can be effectively used immediately as a tread around the vertical axis 10.

It is of course possible to drive the two drives described above simultaneously, whereby two escalators, one for ascending and one for descending, are driven around the vertical axis 9 and around the vertical axis 10, respectively. In this case as well, one of the escalator treads 13 for ascending or descending
Can be efficiently used as the other descending or ascending tread, and the increase in the transport amount due to this is remarkable. On the other hand, known elevators 7 and 8 are arranged in the vertical spaces of the spiral escalators 1, 2 and 11 and 12. In the present invention, the driving devices for the spiral escalators 1, 11 and 2, 12 can be provided at positions other than the respective vertical spaces, so that the elevators 7, 8 can be sufficiently arranged as described above. It is. This allows, for example,
Handicapped persons or cargo, luggage for passengers, etc. can be carried by the elevator.

FIG. 3 and FIG. 4 (b) show a second embodiment of the present invention. The second embodiment is an example suitable for being provided in a place where the vertical space is relatively small.

The distance between the vertical axes 9 'and 10' shown in FIGS. 3 and 4 (b) is much smaller than the distance between the vertical axes 9-10 in the first embodiment. Around the vertical axis 9 ', a spiral escalator 1' corresponding to, for example, the spiral escalator 1 in the first embodiment, and around a vertical axis 10 ', for example, the spiral escalator in the first embodiment.
The spiral escalator 1 'and the upper end and the lower end of the spiral escalator 11' are connected by connecting members 3 'and 6'. The configuration of the treads and the like is the same as in the first embodiment.

By driving the drive, the spiral escalators 1 'and 11' move in the direction indicated by the arrow, 1 'acting as an ascending escalator and 11' acting as a descending escalator. Also in this case, as in the first embodiment, the tread is effectively used throughout the entire circulation process. In addition, the installation area of the apparatus in this case is extremely small as compared with the first embodiment.

(Effects of the Invention) The main effects of the present invention are as follows.

1) Since the spiral escalator is arranged around the adjacent vertical axis, the installation area is much smaller than that of the conventional inclined escalator, and when the conventional escalator is installed around the vertical axis. As in the above, there are no design restrictions that may occur when a loop-shaped spiral escalator is provided.

2) In the conventional method in which an endless loop-shaped escalator is arranged around one vertical axis, the tread is 1
During circulation rotation, only the outward path functions as a footboard for transporting personnel, but in the present invention, the footboard can always perform the function of occupant transportation throughout the entire circulation rotation process, thereby significantly improving transportation. The amount can be increased.

3) If the occupants of the spiral escalator arranged around the vertical axis 9 and the paired spiral escalator arranged around the vertical axis 10 are equal, the two are opposite to those for ascending and descending. As a result, the weights of both occupants are almost offset, and the driving energy of the driving device is correspondingly small. This concept works even when the weights of the occupants of the two escalators are slightly different, so that it is possible to expect the quenching energy of the driving device.

4) Further, since a well-known elevator is provided in the vertical space of the spiral escalator for exclusive use of the physically handicapped or for transporting passengers' luggage, etc., the overall transport amount is significantly improved as compared with the conventional method. I do.
