1 to 3, there is shown a building 10 equipped with a vertical transportation device according to this embodiment. Building 1
At 0, an elevator hoistway 14 for vertically moving the box-shaped cage 12 is extended in the vertical direction. On the side wall of the elevator hoistway 14, a person's boarding port 16 and a cargo loading port 18 are opened facing each other for each floor. The boarding gate 16 communicates with the elevator lobby 20 on each floor, and the loading port 18 communicates with the cargo handling room 22 on each floor.

The cage 12 is connected to the other end of a wire rope 26 having a counterweight 24 connected to one end thereof. As shown in FIG. 6, the intermediate portion of the wire rope 26 is wound around the drive reel 30 of the hoisting machine 28 provided in the machine room at the top of the elevator hoistway 14. By rotating the drive reel 30, the cage 1
No. 2 is designed to move up and down in a slippery manner. Further, the cage 12 and the counterweight 24 are adapted to be vertically moved by being guided by a guide rail (not shown) vertically arranged on the wall surface of the elevator hoistway 14. Further, a door opening / closing device 15 is provided on the ceiling of each cage 12, and the cage 12 operates in conjunction with a door opening / closing device (not shown) that opens and closes the door 32 of the boarding port 16 and the door 34 of the loading port 18. The human door 36 is opened and closed.

As shown in FIGS. 4 to 5, guide rails 40 extend in the depth direction at the upper and lower corners of the cage 12. The guide rail 40 is a shaped steel material having a box-shaped cross section, and a slit 42 is extended in the longitudinal direction on the side surfaces facing each other in the lateral direction.

A rack 44 is formed on the bottom surface of the guide rail 40 in the longitudinal direction. A pinion 48 meshes with the rack 44. Left and right pinion 4
8 are coaxially connected by a shaft 46. The shaft 46 is axially supported by upper and lower frames of a movable partition wall 54 that partitions the cage 12 into a space 50 for people and a space 52 for cargo. As a result, the movable partition wall 54 slides along the guide rail 40, and the volumes of the space 50 for people and the space 52 for freight can be varied.

On the other hand, a gear 38 is fixed to the center of a shaft 46 axially supported by the upper frame of the movable partition wall 54. The gear 38 meshes with a gear 58 of a stepping motor 60 fixed to a racket 61 arranged on the upper frame. A sprocket 64 is attached to the left end of the upper and lower shafts 46.
A chain 68 housed in a vertical frame is wrapped around each.

As a result, the rotational force of the stepping motor 60 is transmitted to the lower shaft 46 through the upper shaft 46, and the respective pinions 48 rotate at the same speed to keep the movable partition wall 54 while maintaining the vertical state. It is moved along the guide rail 40. Further, since the stepping motor 60 can hold the position with a high torque in the stopped state, the pinion 48 does not rotate carelessly and the movable partition 54 does not slide.

On the other hand, the vertical frame of the movable partition wall 54 projects outward by an amount corresponding to the thickness of the guide rail 40.
It is in contact with the lateral wall of the cage 12. In addition, the movable partition 54
The outer peripheral surface of is recessed, and this recessed portion is covered with a thick rubber sheet 69. A push plate 71 is arranged inside the rubber sheet 69, and both ends of the push plate 71 are connected to the solenoid 70.
Supported by.

When electricity is applied to the solenoid 70, the push plate 71 is pushed out by magnetic force to push the rubber sheet 69 against the ceiling, floor surface and wall surface of the cage 12 to lock the movable partition wall 54, and at the same time as the cargo space 52 and the person. Space 50
It is designed to maintain airtightness with. Therefore, the odor generated from the cargo is prevented from leaking into the human space 50.

In the elevator hoistway 14, a power supply line is arranged vertically. A current collecting shoe that is in contact with the power supply line is attached to the cage 12 so as to correspond to the power supply line. Electric power is supplied to the cage 12 from the power supply line through the current collecting shoe, and the lighting in the cage 12 and the door opening / closing device 1
5, used for operating the stepping motor 60, the solenoid 70, and the like. Further, as shown in FIG. 6, an information cable 74 is arranged near the power supply line along the passage. The information cable 74 is composed of a leaky coaxial cable, which radiates a signal being transmitted as a leak magnetic flux to the surroundings and receives a signal from the cage 12. An antenna for receiving a signal leaked from the information cable 74 is attached to the cage 12, which enables communication between the inside and the outside of the cage 12 and detects the position of the cage 12.

The information cable 74 is connected to the control device 76. The position information of each cage 12 detected via the information cable 74 is input to the control device 76. An operation panel 78 operated by a user is attached inside the cage 12. The user operates the operation panel 7
When the destination is specified by operating 8, the destination is transmitted as a signal from the above-mentioned transmitting device and is input to the control device 76 via the information cable 74. Further, the cage 12 has an infrared sensor 80 as a user detecting means.
Is attached and is connected to the control device 76 together with the door opening / closing device 15, the stepping motor 60, and the solenoid 70 via the information cable 74.

Further, a call button 82 for the user to call the cage 12 is attached to each boarding gate 16. Each call button 82 is connected to the controller 76. The controller 76 detects the call of the cage 12 from the user by operating the call button 82.

A call button 8 for calling the cage 12 by a user who transports the cargo M is provided at each loading port 18.
4 is attached. Each call button 84 is connected to the controller 76. The control device 76 uses the call button 8
When the user operates the box 4, the call of the cage 12 from the user is detected. The controller 76 is programmed to give priority to the call button 82 over the call button 84.

Next, the operation of the vertical transportation device will be described. The control device 76 is input with the patterns of the amount of transportation of people and freight by time of day.

During a period of high human utilization (at work, at lunch, when leaving the office, etc.), a predetermined pulse is input to the stepping motor 60 via the driver. As a result, the stepping motor 60 rotates by a predetermined amount. As a result, the shaft 46, to which the gear 38 meshing with the gear 58 is fixed, rotates, and the pinion 48 rotates. Further, the sprocket 64 and the chain 68 also rotate the lower pinion 48.

As a result, the four pinions 48 rotate at the same speed, and the movable partition wall 54 moves to the mounting port 18 side along the guide rail 40 while maintaining the verticality. Therefore, the space 50 for the person becomes the same as the accommodation space of the cage 12, and it becomes possible to transport a person with a maximum capacity. Also,
The occupant does not feel anxiety due to the tilting of the movable partition wall 54.

Since the stepping motor 60 holds the position with a high torque in a stopped state, the pinion 48 does not rotate carelessly and the movable partition wall 54 does not rattle.
As a precaution, the solenoid 70 is excited to extrude the rubber sheet 69 to lock the movable partition wall 54 and, at the same time, maintain the airtightness of the human space 50.

Also, in a time zone when the rate of use of the person is excessive (when working, etc.), the stepping motor 60 is operated to move the movable partition wall 54 so that the space 50 for the person and the space 52 for the cargo are halved. Partition into This allows cargo and people to be transported at one time, so there is no need to separately provide a cage for people and a cage for cargo, which simplifies control and installs a hoistway corresponding to that. Since there is no need, the construction cost can be reduced.

The space 50 for people and the cargo space 5
The amount of movement of the movable partition wall 54 separating the two can be set in advance according to the number of persons and the amount of cargo unique to each building.

Next, during a time period when the human utilization rate is low, the infrared sensor 80 detects the presence / absence of a user in the cage 12. If it is determined that there are no users in the cage 12,
The stepping motor 60 is actuated to press the movable partition wall 54 against the boarding gate 16 so that the cargo space 52 is maximized. As a result, the entire cage 12 can be used as a cargo space, and the transportation capacity is improved.

In the present embodiment, the operation pattern is stored in the control device and the movable partition 54 is moved at each time, but the operation manager moves the movable partition 54 by manual operation as necessary. You may do it.
