Description

  The present invention relates to an elevator control apparatus in which two passenger cars are connected.

  A generally known elevator is called a single deck elevator, and a single car is installed in a hoistway, and the car is driven by a hoisting machine. If such a single deck elevator is installed in a building according to usage such as passenger, luggage, emergency, VIP, etc., there is a problem that the elevator occupation area of the building becomes very large.

On the other hand, in recent years, multi-car elevators (see, for example, Patent Document 1) have been developed that provide a plurality of cars in the same hoistway and control each individually as an elevator that suppresses the elevator occupation area of a building.
JP 2003-160283 A

  However, in the above-described multi-car elevator, each car travels independently, so that complicated operation control for avoiding collision between cars is required, and the cost is very high.

  The present invention has been made in view of the above points, and provides an elevator control device that can use each car safely and inexpensively according to applications and can reduce the area occupied by an elevator in a building. With the goal.

  The elevator control apparatus according to the present invention includes a first car that moves in the hoistway, a second car that is connected to the first car in the up-and-down direction and moves together with the first car. Driving control means for switching between the driving of the first car and the driving of the second car at a predetermined timing and controlling so as not to get on the first and second cars at the same time. Configured.

  According to the present invention, in an elevator in which two passenger cars are connected, it is possible to use each passenger car safely and at low cost by switching the operation of each passenger car so as not to get on at the same time. As a result, the area occupied by the elevator in the building can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram showing a configuration of a double deck elevator according to a first embodiment of the present invention. A double deck elevator is an elevator that operates with two passenger cars connected vertically.

  An elevator control panel 11, a motor 12, a hoisting machine 13, and the like are provided in a machine room 10 at the top of the building. The elevator control panel 11 exists as a main control device of the elevator, and is configured by a computer equipped with a CPU, a ROM, a RAM, and the like. The elevator control panel 11 controls the entire elevator such as drive control of the motor 12. The motor 12 is an electric motor for rotationally driving the hoisting machine 13.

  A rope 14 is wound around the hoisting machine 13, and a car frame 15 is connected to one end thereof and a counterweight 16 is connected to the other end. The car frame 15 has two passenger cars 15a and 15b. Hereinafter, the upper car 15a is referred to as an “upper car” and the lower car 15b is referred to as a “lower car”.

  The upper car 15a and the lower car 15b are connected by a mechanism (not shown) in the up and down direction. The counterweight 16 has substantially the same weight as the entire car frame 15 and is balanced with the car frame 15.

  In such a configuration, when the motor 12 is driven in response to a command from the elevator control panel 11, the hoisting machine 13 rotates, and accordingly, the car frame 15 together with the counterweight 16 and the hoistway 17 through the rope 14. Move in a slewing style. At that time, the upper car 15a and the lower car 15b in the car frame 15 move simultaneously.

  Here, the double deck elevator is usually intended for mass transportation, and passengers are put on both the upper car 15a and the lower car 15b to move between the floors. In this embodiment, in such a double deck elevator, by individually controlling the upper car 15a and the lower car 15b, for example, the upper car 15a is used for emergency, and the lower car 15b is used for normal riding. Enable use. In addition, for example, when the car 15a is used as a VIP car and the lower car 15b is used as a luggage car, the decoration in the car can be differentiated.

  However, since elevator cars having different usages are arranged up and down, it is necessary to separately control the operation control of the upper car 15a and the operation control of the lower car 15b without getting on the upper car 15a and the lower car 15b at the same time.

Hereinafter, operations related to the operation control will be described in detail.
FIG. 2 is a flowchart showing an operation control operation of the elevator control panel 11 in the first embodiment, and shows an operation for preventing the passenger from getting on the upper and lower cars at the same time. In addition, the process shown by this flowchart is performed when the elevator control panel 11 which is a computer reads a predetermined program.

  First, the elevator control panel 11 acquires the operation information of the upper car 15a and the lower car 15b. This driving information includes information on the car call of the upper car 15a and the lower car 15b and the hall call on each floor.

  The “car call” is call information generated by operating a car call button (not shown) (also referred to as a destination floor button) installed in the car. “Place call” is call information generated by operation of a hall call button (not shown) (also referred to as a destination direction button) installed at a hall on each floor. The elevator control panel 11 causes the upper car 15a or the lower car to be called. Assigned to the car 15b.

  Here, if there is a car call for the upper car (Yes in Step S1) or if there is a hall call for the upper car (Yes in Step S3), the elevator control panel 11 is currently under the lower car control. It is determined whether or not there is (step S7). The “lower car control” means a state in which the operation of the lower car 15b is controlled. Similarly, “upper car control” refers to a state in which the operation of the upper car 15a is controlled.

  If the lower car is not under control (No in step S7), when the lower car 15b is stopped after responding to the car call for the lower car and the landing call (Yes in step S8), the elevator control panel 11 turns off the illumination of the lower car 15b and switches to the upper car control (step S11).

  Similarly, if there is a car call for the lower car (Yes in step S2) or if there is a hall call for the lower car (Yes in step S4), the elevator control panel 11 is currently in the upper car control. It is determined whether or not there is (step S5).

  If the upper car is not being controlled (No in step S5), when the upper car 15a is stopped after the response to the car call for the upper car and the landing call (Yes in step S6), the elevator control panel 11 turns off the illumination of the upper car 15a and switches to lower car control (step S9).

  On the other hand, in other cases (No in step S4, Yes in step S5, No in step S6, Yes in step S7, Yes in step S8), the elevator control panel 11 switches between the upper car 15a and the lower car 15b. No (Steps S10, S12).

  In this way, by controlling so as not to get on the upper and lower cars of the double deck elevator at the same time, the double deck elevator that has been originally used for enhancing the transportation capacity can be used as two single deck elevators. Therefore, it is possible to use each car according to its use safely and at low cost, and the elevator occupation area of the building can be reduced.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  In the second embodiment, when the operation of the upper car 15a and the operation of the lower car 15b are switched, the presence or absence of a passenger in the car on the side to be switched is detected.

  FIG. 3 is a diagram showing a configuration of a double deck elevator according to the second embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same part as the structure of FIG. 1 in the said 1st Embodiment, and the description shall be abbreviate | omitted.

  3 differs from the configuration of FIG. 1 in that a load sensor 21a and an on-floor phototube 22a are installed on the upper car 15a of the car frame 15, and the load sensor 21a detects the load, and the on-floor phototube 22a detects the passage of a passenger. And it is comprised so that the elevator control panel 11 may be notified. Similarly, for the lower car 15b of the car frame 15, the load sensor 21b and the on-floor phototube 22b are installed, the load sensor 21b detects the load, the on-floor phototube 22b detects the passage of the passenger, and the elevator control panel 11 It is comprised so that it may alert | report.

The operation of the second embodiment will be described below.
FIG. 4 is a flowchart showing an operation control operation of the elevator control panel 11 in the second embodiment. In addition, the process shown by this flowchart is performed when the elevator control panel 11 which is a computer reads a predetermined program. Also, the same step numbers are assigned to the same parts as those in the process of FIG. FIG. 2 is different from FIG. 2 in that steps S13 and S14 are added.

  That is, the elevator control panel 11 determines operation switching based on the operation information of the upper car 15a and the lower car 15b (steps S1 to S8). When the operation control is switched from the upper car 15a to the lower car 15b (Yes in step S6), the elevator control panel 11 inputs the signals of the load sensor 21a and the on-floor photoelectric tube 22a installed in the upper car 15a, It is determined whether or not there are passengers in the upper car 15a (step S13).

  Here, when the load detected by the load sensor 21a is within a predetermined range and the passage of the passenger is not detected by the on-floor phototube 22a, it is determined that there is no passenger in the car.

  In this way, when it is confirmed that there is no passenger in the upper car 15a (Yes in Step S13), the elevator control panel 11 turns off the illumination of the upper car 15a and switches to the lower car control (Step S9). Further, when there is a passenger in the upper car 15a (No in Step S13), the upper car 15a and the lower car 15b are not switched (Step S10).

  Similarly, when the operation control is switched from the lower car 15b to the upper car 15a (Yes in step S8), the elevator control panel 11 inputs signals from the load sensor 21b and the floor photoelectric tube 22b installed in the lower car 15b. Then, it is determined whether or not there are passengers in the lower car 15b (step S14).

  When it is confirmed that there are no passengers in the lower car 15b (Yes in step S14), the elevator control panel 11 turns off the illumination of the lower car 15b and switches to the upper car control (step S11). If there are passengers in the lower car 15b (No in step S14), the upper car 15a and the lower car 15b are not switched (step S12).

  Thus, when switching between the upper car 15a and the lower car 15b, it is possible to operate more safely by switching the operation only when there is no passenger by detecting the presence or absence of passengers in the car on the side to be transferred. it can.

  Although it is possible to detect the presence / absence of a passenger only with the load detected by the load sensors 21a and 21b, it may be erroneously detected due to, for example, misplacement of luggage, so that another type of phototubes 22a and 22b on the floor, etc. It is preferable to use a sensor in combination.

  In addition, if the values of the load sensors 21a and 21b are periodically acquired as reference values during maintenance inspections and remote inspections, even if there are errors due to car positions or aging, the above reference values Based on this, the presence or absence of passengers can be accurately detected.

(Third embodiment)
Next, a third embodiment of the present invention will be described.

  In the third embodiment, when a button operation is detected in a non-driving car, the operation is temporarily switched to get off passengers in the car.

  FIG. 5 is a diagram showing a configuration of a double deck elevator according to the third embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the part same as the structure of FIG. 3 in the said 2nd Embodiment, and the description shall be abbreviate | omitted.

  5 differs from the configuration of FIG. 3 in that an operation panel 23a is provided in an upper car 15a of the car frame 15, and the operation signals of the car call button 24a and the door opening button 25a on the operation panel 23a are received. In other words, the elevator control panel 11 is configured as a control signal for switching operation. Similarly, an operation panel 23b is provided in the lower car 15b of the car frame 15, and the elevator control panel 11 uses the operation signals of the car call button 24b and the door opening button 25b on the operation panel 23b as control signals for operation switching. It is configured to give to.

  Further, sensor separation switches 26a and 26b are installed on the operation panels 23a and 23b. The sensor separation switches 26a and 26b are used to invalidate the input of signals when the on-floor phototubes 22a and 22b used as human sensors fail.

  A similar sensor separation switch 28 is also provided for the monitoring panel 27. The monitoring panel 27 is connected to the elevator control panel 11 via a communication line, and remotely monitors elevator operation information. The operation of the sensor disconnecting switch 28 installed on the monitoring panel 27 can also invalidate the inputs to the on-floor phototubes 22a and 22bb.

The operation of the third embodiment will be described below.
6 and 7 are flowcharts showing the operation control operation of the elevator control panel 11 in the third embodiment. In addition, the process shown by this flowchart is performed when the elevator control panel 11 which is a computer reads a predetermined program. The same step numbers are assigned to the same parts as those in the process of FIG. 4 is different from FIG. 4 in that processing in steps S15 to S23 is added.

  That is, it is assumed that the car call button 24a or the door open button 25a of the upper car 15a is operated during the lower car control (Yes in Step S15) (Steps S1 and S16). In such a case, the elevator control panel 11 determines that there are passengers in the non-operating upper car 15a and responds to all forward car calls of the lower car 15b (step S19), and then temporarily By switching to the upper car control, the passengers in the upper car 15a get off at the nearest floor (step S20).

  Similarly, when the car call button 24b or the door open button 25b of the lower car 15b is operated during the upper car control (Yes in step S17) (steps S2 and S18), the elevator control panel 11 is not operated. After determining that there are passengers in the lower car 15b in the middle and responding to all forward car calls of the upper car 15a (step S21), by temporarily switching to the lower car control, The passenger gets off at the nearest floor (step S22).

  In step S19 or step S21, if all the car calls are not answered, the elevator control panel 11 does not switch between the upper car 15a and the lower car 15b (step S23).

  Other processes are the same as those in FIG. That is, the elevator control panel 11 determines operation switching based on the operation information of the upper car 15a and the lower car 15b (steps S1 to S8). When the operation control is switched from the upper car 15a to the lower car 15b (Yes in step S6), the elevator control panel 11 inputs the signals of the load sensor 21a and the on-floor photoelectric tube 22a installed in the upper car 15a, It is determined whether or not there are passengers in the upper car 15a (step S13).

  When it is confirmed that there is no passenger in the upper car 15a (Yes in step S13), the elevator control panel 11 turns off the illumination of the upper car 15a and switches to the lower car control (step S9). Further, when there is a passenger in the upper car 15a (No in Step S13), the upper car 15a and the lower car 15b are not switched (Step S10).

  Similarly, when the operation control is switched from the lower car 15b to the upper car 15a (Yes in step S8), the elevator control panel 11 inputs signals from the load sensor 21b and the floor photoelectric tube 22b installed in the lower car 15b. Then, it is determined whether or not there are passengers in the lower car 15b (step S14).

  When it is confirmed that there is no passenger in the lower car 15b (Yes in Step S14), the elevator control panel 11 turns off the illumination of the lower car 15b and switches to upper car control (Step S11). If there are passengers in the lower car 15b (No in step S14), the upper car 15a and the lower car 15b are not switched (step S12).

  In this way, even if a passenger accidentally gets in the car that is not driving, it is possible to cause the passenger to get off at the nearest floor by switching the operation temporarily by operating the button in the car. it can.

  Further, when the on-floor phototubes 22a and 22b break down for some reason, the operation as a normal double deck elevator can be continued by operating the sensor disconnection switch 26a or 26b from the upper car 15a or the lower car 15b. This also applies to the operation of the sensor separation switch 28 provided on the monitoring panel 27.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.

  In the fourth embodiment, when the operation of the upper car 15a and the operation of the lower car 15b are switched, the fact is notified to the car or the landing.

  FIG. 8 is a diagram showing a configuration of a double deck elevator according to the fourth embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same part as the structure of FIG. 5 in the said 3rd Embodiment, and the description shall be abbreviate | omitted.

  8 differs from the configuration of FIG. 5 in that a notification device 29a is provided in the upper car 15a of the car frame 15 and a notification device 29b is provided in the upper car 15b. These notification devices 29a and 29b are connected to the elevator control panel 11, and when switching between the operation of the upper car 15a and the operation of the lower car 15b, a notification to that effect is displayed or by voice.

  A similar notification device 31 is also installed at the hall 30 on each floor. This notification device 31 is connected to the elevator control panel 11, and when switching between the operation of the upper car 15a and the operation of the lower car 15b, notifies that effect by display or voice.

The operation of the fourth embodiment will be described below.
FIG. 9 is a flowchart showing the operation control operation of the elevator control panel 11 in the fourth embodiment. In addition, the process shown by this flowchart is performed when the elevator control panel 11 which is a computer reads a predetermined program. Also, the same step numbers are assigned to the same parts as those in the process of FIG. FIG. 2 is different from FIG. 2 in that steps S24 and S25 are added.

  That is, when the operation control is switched from the upper car 15a to the lower car 15b (Yes in step S6), the elevator control panel 11 may, for example, “switch the operation. Be careful because this elevator cannot be boarded”. Then, it is notified through the notification device 29a installed in the upper car 15a that the upper car 15a cannot be boarded (step S24). Moreover, you may perform the same alerting | reporting through the alerting | reporting apparatus 31 installed in the landing 30 of the floor where the said upper cage | basket | car 15a has stopped at that time.

  After performing such notification, the elevator control panel 11 turns off the illumination of the upper car 15a and switches to lower car control (step S9).

  Similarly, when the operation control is switched from the lower car 15b to the upper car 15a (Yes in step S8), the elevator control panel 11 is, for example, “the operation is switched. ”Please note”, it is notified through the notification device 29b installed in the lower car 15b that it is not possible to get on the lower car 15b (step S25). Moreover, you may perform the same alerting | reporting through the alerting | reporting apparatus 31 installed in the landing 30 of the floor where the said lower cage | basket | car 15b has stopped at that time.

  After performing such notification, the elevator control panel 11 turns off the illumination of the lower car 15b and switches to upper car control (step S11).

  In this manner, when switching between the operation of the upper car 15a and the operation of the lower car 15b, the fact is notified to the inside of the car or the landing so that the car is not accidentally opened due to the final car call or the like. be able to.

  As described above, by switching the operation of the upper and lower cars in the double deck elevator and controlling them so as not to get on at the same time, it can be used as a single deck elevator having a different usage. Accordingly, it is possible to use each car for each application safely and at low cost without requiring complicated control as in the case of a multi-car elevator, and the area occupied by the elevator in the building can be reduced.

  In the present invention, even a double deck elevator is operated by switching between an upper car and a lower car. For example, in the event of a failure or control operation, the upper and lower cars are not rescued at the same time, but are being controlled. Rescue operation of the cage only.
