Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for operating a vertical conveyor, and more particularly, it has a plurality of cages in each of an ascending passage and a descending passage, and the cages are provided in the other passage by an upper switching device and a lower switching device. The present invention relates to an elevator operation system that is a vertical transfer device that can be switched and circulated for operation and that the switching device can move a cage to a standby portion.

[0002]

2. Description of the Related Art Regarding a vertical conveying apparatus, the present applicant has proposed a linear motor drive elevator in Japanese Patent Application No. 3-83728.

[0003]

The above-mentioned proposal itself is effective, but the number of cages operating in circulation is the same in the number of installed cages during both large-volume transportation and small-volume transportation, which causes a loss in operating costs. However, if a defective cage occurs, the circulating operation will stop.

It is an object of the present invention to propose an operation method of a vertical transfer device that can operate a cage according to the amount of transportation and that can continue operation even if a defective cage occurs.

[0005]

According to the operation method of a vertical conveyor according to the present invention, a plurality of cages are provided in each of an up passage and a down passage, and the cages are moved to the other passage by an upper switching device and a lower switching device. You can switch to cycle operation,
Further, in the vertical transfer device capable of moving the cage to the standby unit by the switching device, all the cages are circulated during large-volume transfer, and unnecessary cages or failed cages are transferred to the standby unit during small-volume transfer or when a defective cage occurs. And move the rest of the cages in circulation.

[0006]

In the vertical transfer device having the above-described structure, for example, an elevator, all the cages are circulated during mass transfer, that is, during rush hour.

Further, when the small quantity is not conveyed, that is, when it is not in the rush hour, the surplus number of cages are moved to the waiting place and made to stand by to reduce the operation loss.

Further, for example, when a faulty cage is generated in the upstream passage and operation becomes impossible, the subsequent cage is raised and connected, and the faulty cage is pushed up to the upper switching device by the subsequent cage and moved to the standby place. To repair and continue operation.

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

1 to 3, a plurality of cages 3a to 3c and cages 3d to 3f (3 in the illustrated example) are provided in the ascending path 1 and the descending path 2 (reference numeral 3 in the following description). (Used) is stored so that it can be raised and lowered. Figure 4
See also, for example, the cages 3a and 3f are provided with doors 4 on opposite sides, respectively, and guide rails 5
Are guided by two pairs of upper and lower guide rollers 6 ... And are moved up and down by a rack and pinion type elevation drive device 7.

On the top surface of the cage 3a, a pair of brackets 8 and 8 which are expanded and contracted by a cylinder (not shown) are provided, and the extended brackets 8 and 8 are inserted into the cable plates 10 and 10, respectively. .. A counterweight 12a is connected to the plate 10 via a sheave block 11, and similarly, a counterweight 12b is connected to the cage 3b.

On the other hand, an upper switching device 20 is erected on the floor of the floor FT1 above the uppermost floor FT. This device 20
The support shaft 22 on a swivel (not shown) is provided with a rotatable grab 24 that holds the cylinder of the cage 3 via an arm 23 that can be raised and lowered. Then, when the cage 3 a is supported by the glove 24 and the cylinders are contracted to remove the brackets 8 and 8 from the cable plates 10 and 10, the cable plates 10 and 10 are held by the lower edge portion of the sheave block 11. Then, in FIG. 1, after the cage 3a is pulled up to the position 3a1, the cage 3a is swung to the position 3a2 and lowered to the similar cable plate 1 (not shown) in the down passage 2.
The cages 3a are switched from the ascending passage 1 to the descending passage 2 by inserting the brackets 8 and 8 into 0 and 10 and removing the grab 24. Reference numeral 13 is a drive device for the sheave block 11, 14 is a counterweight guide rail, 15 is a cage suspension wire rope, and 16 is a standby space defined laterally of the passages 1 and 2.

According to the present invention, even when the cage is moved up and down by a linear motor (not shown), a wire rope hoisting mechanism (reference numeral 13 in FIG. 1) in a normal elevator is used.
It should be noted that the present invention can be applied to all cases, even if it is performed by the driving device shown in FIG. 4) or if the rack and pinion drive is performed by the driving device shown by reference numeral 7 in FIG.

On the floor of the floor FB1 below the lowest floor FB, a lower switching carriage 30 is provided so as to be able to travel on rails 31 and 31, and a standby space 32 is provided at one end of the rails 31 and 31. Well defined. Support shaft 3 for this trolley 30
A glove 35 that supports the bottom of the cage 3 via an arm 34 that can move up and down is provided on the unit 3. Also, floor FB
A lower cable plate lock device 36 is provided on the floor of the. Then, after the cage 3f is supported by the glove 35 and the cable plate 10 is locked by the lock device 36, the brackets 8, 8 are pulled out from the cable plates 10, 10 in the same manner as described above. Therefore, the cage 3f is pulled down to the position 3f1, the carriage 30 is driven to move to the position 3f2 and raised, and the brackets 8 and 8 are inserted into the cable plates 10 and 10 (not shown) of the passage 1 and the glove 35 is lowered. 3f is switched from the down path 2 to the up path 1.

With such a construction, during a large amount of transportation, that is, during rush hour, the three cages 3a to 3c and the cages 3d to 3f in the ascending passage and the descending passage 2 are switched over to the upper switching device 2.
0 and the lower switching cart 30 are switched from the up passage 1 to the down passage 2 and from the down passage 2 to the up passage 1 for circulation operation.

When the small quantity is not conveyed, that is, the rush hour is not reached, the standby spaces 16 and 32 are made to stand by the surplus number of cages 3 and the remaining few cages 3 are circulated. Moreover, as shown in FIG. 5, five cages 3a to 3e are provided.
When the driving device 7 of the cage 3b is out of order while the vehicle is operating, for example, when the driving device 7 of the cage 3b becomes inoperable, the passenger of the cage 3b is lowered as shown in FIG.
Raise. Then, as shown in FIG. 7, the cage 3b
The cage 3c is connected to the cage 3c by the glove 9 provided under the floor, and the faulty cage 3b is moved to the top floor FT. Then, as shown in FIG. 8, the cage 3b is supported by the upper switching device 20 to remove the brackets 8 and 8 from the cable plates 10 and 10,
The connection of the grab 9 is released, the cage 3b is pulled up to the floor FT1, the arm 23 is turned to the standby space 17 side to move to the position 3b1, and is lowered to the standby space 17 for repair.

9 and 10 show another embodiment of the present invention, for example, in a high-rise building on the 40th floor, a first elevator A up to F10 on the 10th floor, a second elevator B up to F20 on the 20th floor, and the top. This is an example in which a third elevator C up to the floor FT is provided. In this embodiment, 10th floor 10F, 20th floor 20
Up to F and the top floor FT, it is possible to perform detailed operation management by adjusting the number of operating vehicles during and without rush hour, respectively.

[0018]

As described above, according to the present invention, the operating cost can be reduced by circulating the number of cages according to the amount of transportation and operating the failed cages for repair. ..
