DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below. FIG. 1 is a configuration diagram of an elevator according to an embodiment of the present invention. The building shown in FIG. 1 is an example of a building such as a department store on the first basement floor and four floors above ground, where a restaurant street etc. is provided on the top floor and product floors are provided on the other floors. The hoistway 1 is provided at a position close to the side wall surface of the building. A car 2 moves up and down in the hoistway 1. The car 2 is lifted and lowered by the sheave 4 driven by the hoisting machine 3 through the rope 5 and in balance with the counterweight 6. This car driving system may be other systems such as a hydraulic system and a linear motor system.
On the first floor, the second floor, the third floor, and the fourth floor located inside the building across the hoistway 1, there is a landing point that connects to the product section, which is a non-restricted area that does not restrict the entrance of users during the business hours of department stores. 7f is a platform 7f that is provided on the opposite side of the ground floor 1b across the hoistway 1 and that can enter and leave the building, but is prohibited during business hours of department stores Is provided.
The car 2 has two parts including a front door 2a and a rear door 2b. In the car 2, there are a button for generating a car call and an in-car operation panel 8 having a door opening / closing pushbutton switch. A passenger detection device (not shown) and an in-car notification device 9 are provided. The in-car operation panel can also be provided in the vicinity of each door 2a, 2b.
[0006]
The in-car output device 9 outputs sound and display for notifying the operation details of the elevator, and similarly, a landing output device (not shown) is provided at the landing.
A landing call registration device 10 having a button for generating a landing call is provided at each landing of the hoistway 1.
On the other hand, the control device 11 for controlling the operation of the car 2 is connected to the in-car operation panel 8, the in-car output device 9, the landing call registration device 10, the hoisting machine 3, and the like. It is provided in a three-sided door pocket constituting the side door. For the car 2 having the front door 2a and the back door 2b in both the front and rear directions, the control device 11 opens and closes only the door on the side that responds to the landing call during the normal business hours of the department store. Service is provided between the landings 7a, 7b, 7c, 7d, and 7e (the right-hand side of the illustrated hoistway) that communicate with the merchandise sales floor by the operation mode (first operation mode) in which the one-side door operation is prohibited. When the normal business hours of the department store are over, the two-door operation mode (second operation mode) that opens and closes only the door on the opposite side to the door that responds to the hall call is the second operation mode. Service is provided only between the inside and outside of the platform 7f that can enter and exit. That is, the first operation mode and the second operation mode are switched depending on the time zone. This operation mode can be switched by providing a key switch (not shown) attached to the landing call registration device 10 so that an attendant can manually switch it by key operation. Since it is a fixed time every day except for special cases, there is no need for the staff to change each time, and it is set in advance by a timer provided in the control device 11 so that it is automatically changed every day at a fixed time. You can also.
[0007]
FIG. 2 is a block configuration diagram of the control device 11. When a call is input from the in-car operation panel 8 or the landing call registration device 10, the control device 11 registers the call and generates a call to that effect in the in-car operation panel 8 or the landing call registration device 10. Call response means 12 for notifying, notifying means 13 for notifying the car output device 9 and the landing output device of the operation status of the elevator, and operation control means for controlling the operation of the car 2 in accordance with the call registered in the call response means 12 14, opening / closing means 15 for opening and closing the door, and passenger detection means 16 for determining whether or not a user is present in the car 2. Now, assuming that the operation mode is the first operation mode, a landing call is generated by pressing a call button in the landing call registration device 8 on any floor on the right side of the hoistway 1. In this first operation mode, the landing call registration device 8 at the landing 2f does not operate. When the landing call is generated, the call response means 12 registers the landing call and notifies the landing call registration device 8 that has generated the call to that effect. When the call answering means 12 registers the landing call, the notifying means 13 outputs it to the car output device 9 and the landing output device 9.
Further, when there is a notification of registration of the landing call from the call answering means 12, the driving control means 14 drives the car 2 to make the car 2 respond to the landing call when there is no landing call currently being processed. The car driving command is output to the hoisting machine 3 and the car 2 is driven to the floor where the landing was called. When the car 2 arrives at the floor where the landing is called, the door opening / closing means 15 opens the landing door on the side where the landing is called and the front door 2a.
[0008]
In this state, the passenger detection means 16 detects whether or not the user has entered the car 2. When the passenger detection means 16 detects that the user has entered the car 2 and the user presses the destination floor button of the in-car operation panel 8, the call response means 12 is caused to generate a car call. Command is output. In the case of the first operation mode, it is possible to land on the platform on all floors on the right side of the hoistway 1.
When a car call is generated from the call response means 12, the operation control means 14 outputs a command to the door opening / closing means 15, closes the landing door and the front door 2a, and drives the car 2 to the car call destination floor. Further, when a car call is generated from the call response means 12, the notification means 13 outputs information on the direction in which the door is opened to the in-car output device 9. When the car 2 arrives at the car call destination floor, the operation control means 14 outputs a command to the door opening / closing means 15 to open the landing door and the front door 2a.
In this state, the operation control means 14 determines whether or not a landing call has occurred on the landing floor based on the information from the call response means 12, the landing call has not occurred and the inside of the car 2 When no user is present, a command is output to the door opening / closing means 15, the landing door and the front door 2a are closed, and the one-side door operation is terminated. When the landing call is registered in the call response means 12, the registered landing call is answered. Also, there is no landing call on the landing floor, but when there is a user in the car 2, the operation control means 14 outputs a command to the notification means 13 and an abnormal condition has occurred. Determine whether or not. The notifying means 13 determines whether or not the door closing button has been pressed, and if the door closing button has not been pressed even though there is a user in the car 2, the car is passed after a predetermined time has elapsed. An alarm is generated for the internal output device 9 and the landing output device. This is because it is considered an abnormal situation in which the user could not get off for some reason.
[0009]
After landing in response to the car call, when there is no landing call on the landing floor and the user is in the car 2 and the door close button is pressed, the landing door and the front door 2a are closed, When there is no car call or landing call after closing the door 2a, an alarm is generated in the car output device 9 and the landing output device after a predetermined time has elapsed. Similarly, in this case, it is considered that this is an abnormal situation in which the user could not get off for some reason.
When the first operation mode is switched to the second operation mode, only the landing call registration devices 10 at the landings 2f and 2e operate, and the other landing call registration devices do not operate.
A landing call is generated by pressing a call button in the landing call registration device 8 at either the landing 2e or 2f. When the landing call is generated, the call response means 12 registers the landing call and notifies the landing call registration device 8 that has generated the call to that effect. When the call answering means 12 registers the landing call, the notifying means 13 outputs it to the car output device 9 and the landing output device.
Further, when there is a landing call registration notification from the call response means 12, the driving control means 14 drives the car 2 to make the car 2 respond to the landing call when there is no landing call currently being processed. A car driving command is output to the hoisting machine 3, and the car 2 is driven to one of the floors where the landing call was made. When the car 2 arrives at the floor where the landing is called, the door opening / closing means 15 opens the landing door and the car door on the side where the landing is called.
[0010]
In this state, the passenger detection means 16 detects whether or not the user has entered the car 2. When the passenger detection means 16 detects that the user has entered the car 2 and the user presses the destination floor button of the in-car operation panel 8, the call response means 12 is caused to generate a car call. Command is output.
When a car call is generated from the call response means 12, the operation control means 14 outputs a command to the door opening / closing means 15, closes the landing door and the car door, and drives the car 2 to the other destination floor. Further, when a car call is generated from the call response means 12, the notification means 13 outputs information on the direction in which the door is opened to the in-car output device 9. When the car 2 arrives at the destination floor, the operation control means 14 outputs a command to the door opening / closing means 15 to open the landing door and the car door on the side opposite to the side where the landing call is made.
FIG. 3 is a flowchart showing the operation of the control device.
Monitoring is constantly performed until a landing call is generated (step S1), and at the time of occurrence, the door is opened in response to the landing call (step S2).
Here, it is determined whether or not the car call button on the destination floor has been pressed (step S3). If the car call button has not been pressed, the car call registration promotion on the in-car operation panel is notified (step S4). Wait for a predetermined time (step S5). Thereafter, it is determined whether or not there are passengers in the car (step S6). If there are passengers in the car, the door is opened, an alarm is output (step S7), and the process ends. If there is no user in the car, the door is closed, the notification is canceled (step S8), and the start standby state is restored. This is because the car call operation is not performed despite the response to the landing call.
[0011]
Returning to step 3, when the car call button is pressed, the door is closed and the car is driven toward the car call destination floor (step S9). After landing on the car call destination floor, the door is opened (step S10).
Here, it is determined whether or not there is a landing call on the landing floor (step S11). If there is a landing call, the process returns to the car call button press determination process on the in-car operation panel in step S3 and the process is repeated. If there is no landing call, the presence / absence of passengers in the car is determined again (step S12). If no passengers are detected, the door is closed, the end of operation is notified, and the start standby state is returned. (Step S13).
If a passenger is detected, it is determined whether or not the door close button has been pressed (step S14). If the door close button has not been pressed, the door is opened after a predetermined time has elapsed (step S15) and an alarm is output. Then (step S7) is completed.
If the door close button has been pressed, the door is closed (step S16), and it is determined whether or not the car call button on the destination floor has been pressed (step S17).
If the car call button has been pressed, the car is driven toward the car call destination floor (step S18). If the car call button is not pressed, it is further determined whether or not a landing call is generated (step S19). If there is a landing call, the door is opened in response to the landing call (step S2), but the landing call must be generated. If so, the car call registration promotion on the destination floor is notified (step S20).
[0012]
Thereafter, after a predetermined time has elapsed (step S15), the door is opened, an alarm is output (step S7), and the process ends.
The car control based on this operation flowchart is performed in the same manner in both the first operation mode and the second operation mode.
In this way, in the first operation mode, by using only the front door 2a of the car 2 between the landings 7a to 7e located on the right side of the hoistway 1 shown in FIG. You can freely go to any floor using the elevator during business hours. When the merchandise section is closed and the second operation mode is automatically set by a manual operation by an attendant or a timer in the control device 11, the service is provided only at the restaurant area 7e and the hall 7f that is the entrance of the building. As a result, it becomes impossible to enter the merchandise store. As a result, there is no need to set up a space to secure a restaurant user's passage in the product floor on the first floor, and the user can be prohibited from entering the product floor without providing a shield for isolation. it can.
Further, the installation cost can be reduced and the use efficiency of the elevator can be increased as compared with the case where an elevator dedicated to the direct operation is provided.
[0013]
In the above-described embodiment, the case of using a car having doors in both the front and rear directions has been described. However, the same can be applied to the case of using a car having doors in the orthogonal direction. Further, the present invention is not limited to a building such as a department store where a restaurant street is provided, but can be similarly applied to a building where a movie theater or an event venue is provided that has a different fishing time zone from other floors.
[0014]
【The invention's effect】
As described above, the elevator according to the present invention includes the first operation mode in which the car is serviced by using one door of the car between the first landing and the third landing, the second landing, and the second landing. By configuring the second operation mode to be serviced between two platforms using two doors of the car depending on the time of day, for example, floors such as beer halls and restaurant streets with different business hours If it is installed in a building such as a department store with a floor such as a product sales floor, there is no elevator dedicated to direct operation, and there is no bulkhead or passage space in the building according to the time of day. After closing, the user can enter the restaurant area directly from outside the building, and can also leave. Moreover, the elevator can be used in a normal usage form even when the floor of the product sales floor is in business hours. Thereby, the installation cost of an elevator can be reduced and the utilization efficiency of an elevator can also be improved.
