  FIG. 1 is an enlarged view of a car portion of a car interval variable double deck elevator according to the present embodiment, and FIG. 2 is an overall view. The double deck elevator according to the present embodiment is installed in a building or the like having uneven floor dimensions, and as shown in FIG. 1, an upper car 2 and a lower car 3 are arranged in an outer car frame 1, and an upper car 2 and The lower car 3 is provided with an adjustment mechanism between the cars. This inter-car adjusting mechanism is a hoisting machine 4 that causes the upper car 2 and the lower car 3 connected by a rope 14 to travel the same distance in the opposite directions.

  The hoisting machine 4 is driven by a car interval adjustment control device 5. That is, the hoisting machine 4 and the car interval adjusting control device 5 function as an inner car adjusting mechanism. The upper car 2 and the lower car 3 are each provided with an inter-car distance measuring device 9, and the car interval adjustment control device 5 is operated in accordance with the measurement results of the inter-car distance measuring device 9 provided on the upper and lower cars. The hoisting machine 4 is driven so that the distance between the cars is recognized and the upper and lower cars are at a desired distance.

  A car position detector 7 is provided in the upper car 2 and the lower car 3 to detect a car position detection plate 8 provided on each floor and output a signal. The door control device 6 also provided in the upper and lower cars controls the opening and closing of the door based on the output signal of the car position detector 7. That is, the car position detection plate 8 functions as a position detection plate, and the car position detector 7 functions as a position detection plate detection unit. Details of the car position detector 7 and the car position detection plate 8 will be described later.

  In the car interval variable double deck elevator configured as described above, the outer car frame 1 is connected to the counterweight 11 by the main rope 13 as shown in FIG. The main rope 13 is driven by the electric motor 10. The electric motor 10 is controlled by the control device 12, whereby the outer car frame 1 and the counterweight 11 are raised and lowered in opposite directions. Each of the upper car 2 and the lower car 3 is provided with a load capacity detection mechanism, and the control device 12 loads the upper car 2 and the lower car 3 on the basis of a signal output from the load capacity detection mechanism. The amount can be recognized. The load amount detection mechanism functions as a load amount detection unit, and for example, a load detector can be used.

  Here, the functional configuration of the control device 12 will be described with reference to FIG. FIG. 3 is a block diagram illustrating a functional configuration of the control device 12. As shown in FIG. 3, the control device 12 includes a door opening / closing control unit 121, an electric motor control unit 122, an operation signal acquisition unit 123, a load amount detection unit 124, a car interval notification unit 125, and a table storage unit 126.

  The door opening / closing control unit 121 inputs a command related to opening / closing of the doors to the door control devices 6 provided in the upper and lower cars, respectively. Further, the door opening / closing control unit 121 acquires the detection signal of the car position detector 7 via the door control device 6 and inputs the detection signal to the motor control unit 122 and the car interval notification unit 125. The electric motor control unit 122 controls the electric motor 10 based on information input from the door opening / closing control unit 121, the operation signal acquisition unit 123, and the load amount detection unit 124. In particular, the motor control unit 122 determines whether the upper and lower cars have landed on the floors based on the detection signal of the car position detector 7 input from the door opening / closing control unit 121 and stops the motor 10.

  The operation signal acquisition unit 123 acquires a signal corresponding to pressing of an operation button such as a door opening / closing button, a destination floor designation button in the upper and lower cars, a call button provided in a hall of each floor, and the motor control unit 122 and Input to the car interval notification unit 125. The load amount detection unit 124 acquires a signal output from a load amount detection mechanism (not shown) provided in the upper and lower cars, detects a load amount of each of the upper and lower cars, and inputs the detected load amount to the motor control unit 122 and the car interval notification unit 125. .

  The car interval notification unit 125 determines the destination floor based on the information input from the operation signal acquisition unit 123, reads out the car interval information corresponding to the destination floor from the table storage unit 126, and sends it to the car space adjustment control device 5. Notice. In addition, the car interval notification unit 125 adjusts the car interval according to the signal input from the stacking amount detection unit 124 and the button press state in each floor and the car input from the operation signal acquisition unit 123.

The table storage unit 126 is a storage unit that stores a predetermined value of the car interval corresponding to the stop floor of the upper car and the lower car. FIG. 4 shows an example of information stored in the table storage unit 126. As shown in FIG. 4, the table storage unit 126 includes an “ID” for identifying each data, an “upper car” indicating a stop floor of the upper and lower cars, a “lower car”, and a “car interval according to the stop floor of the upper and lower cars. Information. For example, when the upper car stops at the “second floor” and the lower car stops at the “first floor”, the interval between the upper and lower cars is “L ₁ ”.

  In such a double deck elevator, the gist according to the present embodiment is that the car interval notification unit 125 reads out from the table storage unit 126 based on information input from the operation signal acquisition unit 123 and the load amount detection unit 124. Adjusting the value of “car interval” and changing the manner in which the motor control unit 122 determines whether the upper and lower cars have landed based on the information input from the door opening / closing control unit 121 and the load detection unit 124. It is in. Hereinafter, control of the double deck elevator according to the present embodiment will be described.

  FIG. 5 is a diagram illustrating a control rule table (hereinafter referred to as a control rule table) based on the detection result of the load amount detection unit 124 and information input from the operation signal acquisition unit 123. As shown in FIG. 5, in the control rule table according to the present embodiment, the “loading amount” of the upper and lower cars, “in-car call” indicating the operation state of the operation buttons in the car, and the operation buttons provided on each floor A “correction pattern” for each condition is defined on the condition of “hall call” indicating the operation state.

  In the control rule table shown in FIG. 5, “loading amount” of “large” indicates that the loading amount detected by the loading amount detection unit 124 based on the detection signal of the loading amount detection mechanism is equal to or greater than a predetermined threshold. . “In-car call” is “present” indicates that there is a person who presses the destination floor designation button in the car with the next stop floor as the destination floor. “Hall call” is “present” indicates that there is a person who presses the button to get on the elevator among the operation buttons provided in the hall on the next stop floor.

  As the predetermined threshold value, for example, a value of 80% of the loadable weight can be used. The positional deviation between the car and the landing is caused by the expansion and contraction of the rope 14 that supports the car. If the rope 14 extends 5 mm at a loading amount of 100%, it extends approximately 4 mm when the loading is 80%. Accordingly, it can be said that the influence of the expansion / contraction amount of the rope 14 when the loading amount is reduced from 80% is large, so that an effective determination can be made by using 80% as a reference.

  In the control rule according to the present embodiment, for example, in the case of the rule of ID “001”, the upper car has a load capacity of “large”, there are calls in the car and the hall call, and the lower car has a load quantity of “small”. Yes, there is no call in the car and there is a hall call. The correction pattern applied at that time is “pattern C”. FIG. 6 shows details of each correction pattern. As shown in FIG. 6, the correction pattern C is “car interval−α”, that is, the interval is narrower than the interval between the cars read out from the table storage unit 126 and detected by the cage position detector provided in the upper cage. The electric motor 10 determines landing based on the signal.

  Specifically, in the case of the rule of ID “001” described above, it is predicted that the load capacity will not change greatly because the upper car has both a car call and a hall call when the load capacity is equal to or greater than a predetermined threshold. Since it is predicted that the position of the car will not change, it is determined that the landing control should be performed based on the detection of the position of the upper car. On the other hand, in the lower car, there is no call in the car when the load amount is less than a predetermined threshold value, but there is a hall call. Therefore, it is predicted that the load amount will increase and the position will drop as the rope extends. Therefore, by narrowing the space between the upper and lower cars, the lower car is landed at a position slightly higher than the reference height, and the amount of deviation from the floor after the load capacity is increased is offset.

  In the case of ID “002”, the upper car has a load capacity of “large” and there is an in-car call and there is no hall call. The lower car has a load capacity of “small” and there is no in-car call, and the hall call is there. In this case, since only the person gets down from the upper car, it is predicted that the load will decrease, the rope will shrink, and the car position will rise. On the other hand, since the lower car is only ridden by people, it is predicted that the load will increase, the rope will extend, and the car position will fall.

  Therefore, in the case of the rule of ID “002”, it is preferable not to adjust the car interval according to a predetermined pattern, but to narrow the car interval as appropriate according to passengers getting on and off. That is, the car interval notification unit 125 outputs a command for narrowing the car interval to the car interval adjustment control device 5 according to the detection signal of the car position detector input from the door opening / closing control unit 121. In addition, the car adjustment control device 5 may automatically adjust the car space based on the output signal of the car distance measuring device 9.

  In the case of ID “003”, the upper car has a load capacity of “large”, and there is an in-car call and hall call. The lower car has a load capacity of “small”, and there is no in-car call and hall call. . In this case, it is predicted that the loading amount will not change significantly in the upper and lower cars, and the car position will not be greatly shifted, so no correction is necessary.

  In the case of ID “004”, the upper car has a load capacity of “large”, there is an in-car call, there is no hall call, the lower car has a load capacity of “small”, and the in-car call and hall call. The correction pattern is pattern B. In this case, since only the person gets down from the upper car, it is predicted that the load will decrease, the rope will shrink, and the car position will rise. On the other hand, since there is no passenger getting in and out of the lower car, it is predicted that the loading capacity does not change and the car position does not change.

  Therefore, as shown in FIG. 6, in the case of pattern B, the landing control is performed based on the detection signal of the car position detector provided in the lower car where the car position does not change. Further, since the car interval increases as the car position of the upper car rises, the car interval read from the table storage unit 126 is adjusted to be narrow in order to cancel out the car interval.

  As described above, the motor control unit 122 is based on the “loading amount” information input from the loading amount detection unit 124 and the “in-car call” and “hall call” information input from the operation signal acquisition unit 123. It is determined whether the detection signal of the car position detector provided in the upper or lower car is used for landing control. This is particularly effective when the flooring accuracy of either one of the upper and lower cars should be increased.

  Further, the car interval notifying unit 125 is based on the “loading amount” information input from the loading amount detection unit 124 and the “inside-car call” and “hall call” information input from the operation signal acquisition unit 123. The necessity and adjustment amount of the car interval read from the table storage unit 126 are determined. Thereby, the shift amount of the car position caused by getting on and off can be minimized.

  The rules as shown in FIG. 5 and FIG. 6 are used when the car is loaded with a large load and the load is greatly increased, or when the car is loaded with a large load and the load is greatly reduced. Paying attention to the most ups and downs of the car, the load capacity of each of the upper car 2 and lower car 3 and the load change expected by calling the inside of the car and the hall, between the car and the floor when getting on and off And the car position detector 7 used for landing control for minimizing the amount of deviation is determined in advance. This makes it possible to perform landing control that minimizes the amount of misalignment due to a change in the loading amount when getting on and off.

  Note that the rules described in FIGS. 5 and 6 are examples, and other rules can be applied. For example, in determining whether to perform landing control using the car position detector 7 of the upper or lower car, in addition to the case where it is expected that the above-described positional deviation due to getting on and off is small, there are passengers in wheelchairs, etc. It can also be taken into account that there are factors that should improve the landing accuracy.

  Next, the car position detector 7 and the car position detection plate 8 according to this embodiment will be described. FIG. 7 is a perspective view showing the car position detector 7 according to the present embodiment. As shown in FIG. 7, the car position detector 7 according to the present embodiment includes a light emitting unit 7a and a detecting unit 7b. As shown in FIG. 7, the light emitting unit 7a and the detecting unit 7b are arranged to face each other, and the detecting unit 7b is configured to receive the light beam emitted from the light emitting unit 7a. When the outer car frame 1 and the upper and lower cars move, the car position detection plate provided on each floor shields between the light emitting unit 7a and the detecting unit 7b, and the detecting unit 7b does not receive the light beam. Thereby, the car position detector 7 determines that the upper and lower cars have landed on each floor.

  Here, the car position detector 7 and the car position detection plate 8 according to the present embodiment have a configuration capable of determining the deviation of the car position. The configuration will be described with reference to FIGS. FIGS. 8A to 8C are views showing the positional relationship between the car position detector 7 and the car position detection plate 8 and the detection range of the car position detector 7 according to the present embodiment. As shown in FIGS. 8A to 8C, the light emitting unit 7a and the detecting unit 7b of the car position detector 7 have three detection ranges “A”, “B”, and “C” in the horizontal direction. is doing. That is, the light emitting section 7a has light emitting elements in the ranges of “A”, “B”, and “C”. The detection unit 7b has a sensor for each range of “A”, “B”, and “C”.

  In addition, as shown in FIGS. 8A to 8C, the car position detection plate 8 detects the car deviation based on the detection results in the above-described detection ranges of “A”, “B”, and “C”. It has a special shape that can be judged. FIG. 8A shows the positional relationship between the car position detector 7 and the car position detection plate 8 when the car position is not shifted. In this case, the detection ranges of “A”, “B”, and “C” are all shielded by the car position detection plate 8. That is, the detection unit 7b does not receive light in any detection range. Thereby, the car position detector 7 outputs a signal indicating that the car is located at an appropriate height.

  FIG. 8B shows the positional relationship when the car position is shifted higher than the appropriate height. In this case, the detection range of “A” and “B” is shielded, but the range of “C” is not shielded, so the sensor of the detection unit 7b provided in the range of “C” receives light. As a result, the car position detector 7 outputs a signal indicating that the car is displaced higher than the appropriate height.

  FIG. 8C shows the positional relationship when the car position is shifted lower than the proper height. In this case, the detection range of “A” and “C” is shielded, but the range of “B” is not shielded, so the sensor of the detection unit 7b provided in the range of “B” receives light. Thereby, the car position detector 7 outputs a signal indicating that the car is shifted lower than the appropriate height. In the case of the “appropriate correction” correction pattern described in FIG. 5, the distance between the upper and lower cars can be corrected based on the detection signal of the car position detector 7.

  Next, operation | movement of the control apparatus 12 in the double deck elevator which concerns on this embodiment is demonstrated with reference to FIG. FIG. 9 is a flowchart showing the processing of the control device 12 when an elevation command is generated in the double deck elevator according to the present embodiment. As shown in FIG. 9, when an elevator command is input by a button operation in a car or a button in a hall, the operation signal acquisition unit 123 acquires the elevator command (S901), and when the destination floor is determined, a car interval notification is made. The unit 125 acquires car interval information corresponding to the destination floor from the table storage unit 126 (S902).

  Then, the car interval notification unit 125 and the motor control unit 122 adjust the car interval based on information input from the door opening / closing control unit 121, the operation signal acquisition unit 123, and the load amount detection unit 124 according to the rules described in FIG. A pattern is determined (S903). A detailed example of S903 will be described in detail later.

  When the car interval adjustment pattern is determined, the car interval notification unit 125 adjusts the car interval according to the determined pattern (S904), and notifies the car interval adjustment control device 5 of it. Then, the electric motor control unit 122 drives the electric motor 10 so that the upper and lower cars are landed on the respective destination floors (S905).

  When the motor control unit 122 drives the motor 10 to move the outer car frame 1 up and down, and landing is determined according to the pattern determined in S903 (S906 / YES), the door opening / closing control unit 121 performs door control. A detection signal of the car position detector 7 for each of the upper and lower cars is acquired via the device 6, and a zone in which the upper and lower cars can be opened and closed (hereinafter referred to as a door zone), that is, the state shown in FIG. It is confirmed whether or not (S907).

  As a result of S907, if both the upper and lower cars are in the door zone (S907 / YES), the door opening / closing control unit 121 transmits a door opening command to the door control device 6. Thereby, the door control device 6 provided in the upper and lower cars drives the upper and lower doors (S908), and the doors are opened. On the other hand, if both the upper and lower cars are not in the door zone as a result of S907 (S907 / NO), the car interval notifying unit 125 notified from the door opening / closing control unit 121 notifies the car adjusting control device 5 of the car interval, The car-to-car adjustment control device 5 adjusts the car interval (S909) and repeats the processing from S907 again. By such processing, the processing of the control device 12 when the elevation command is generated is completed.

  Next, a detailed example of the process in S903 will be described with reference to FIGS. 10 and 11 are flowcharts illustrating a detailed example of the process of S903. In the present embodiment, the processing of S903 is executed by the motor control unit 122 and the car interval notification unit 125, respectively, but after either one is executed, the other may acquire the execution result. . Further, another part in the control device 12 may execute the processing of S903, and the motor control unit 122 and the car interval notification unit 125 may acquire the execution result. In the following description, it will be described as processing by the motor control unit 122, but the same applies to processing by the car interval notification unit 125 and other parts.

  As shown in FIG. 10, first, the electric motor control unit 122 determines whether or not the upper car load amount is equal to or greater than a predetermined threshold based on the information input from the load amount detection unit 124 (S1001). As a result of the determination in S1001, if the loading amount of the upper car is less than the threshold (S1001 / NO), the flow of FIG. 11 is executed (S1002). If the upper car load amount is equal to or greater than the threshold value (S1001 / YES), then the motor control unit 122 determines whether the lower car load amount is less than the predetermined threshold value (S1003).

  As a result of the determination in S1003, if the lower car load is less than the threshold value (S1003 / YES), the motor control unit 122 then proceeds to the destination in the upper car 2 based on the information input from the operation signal acquisition unit 123. It is determined whether or not a button for designating the current destination floor among the floor buttons is pressed, that is, whether there is a call in the upper car (S1004).

  As a result of the determination in S1003, if the lower car load is greater than or equal to the threshold (S1003 / NO), or if the result of the determination in S1004 is that there is no call in the upper car (S1004 / NO), the motor control unit 122 It is determined that correction is unnecessary (S1008), and the process is terminated. On the other hand, if the result of determination in S1004 is that there is a call in the upper car (S1004 / YES), then the motor control unit 122 determines whether the upper car is on the destination floor based on the information input from the operation signal acquisition unit 123. It is determined whether or not the hall call button is pressed, that is, whether or not there is an upper car hall call (S1005).

  As a result of the determination in S1005, when there is a hall call of the upper car (S1005 / YES), the motor control unit 122 then determines the hall of the lower car at the target floor based on the information input from the operation signal acquisition unit 123. It is determined whether or not the call button is pressed, that is, whether or not there is a hall call for the lower car (S1006). If there is a hall call for the lower car (S1006 / YES), the motor control unit 122 determines that the correction pattern is pattern C (S1007), and ends the process. On the other hand, if there is no hall call for the lower car (S1006 / NO), the motor control unit 122 determines that correction is unnecessary (S1008), and ends the process.

  If there is no hall call for the upper car as a result of the determination in S1005 (S1005 / NO), next, the motor control unit 122 determines whether there is a hall call for the lower car as in S1006 (S1009). ). As a result of the determination in S1009, if there is a hall call of the lower car (S1009 / YES), the motor control unit 122 determines that the correction is not made in advance but appropriately corrects it (S1010), and ends the process. As a result of the determination in S1009, if there is no lower car hall call (S1009 / NO), the motor control unit 122 determines that the correction pattern is pattern B (S1011), and ends the process.

  Next, processing in the case where the upper car load amount is less than the predetermined threshold value in S1001 of FIG. 10 (S1001 / NO) will be described with reference to FIG. In this case, the electric motor control unit 122 determines whether the lower car load amount is equal to or greater than a predetermined threshold based on the information input from the load amount detection unit 124 (S1101). As a result of the determination in S1101, if the lower car load is less than the threshold (S1101 / NO), the motor control unit 122 determines that correction is not necessary (S1106), and ends the process.

  If the result of the determination in S1101 is that the lower car load is greater than or equal to the threshold value (S1101 / YES), then the motor control unit 122 calls the lower car in the car based on the information input from the operation signal acquisition unit 123. It is determined whether or not there is (S1102). As a result of the determination in S1102, if there is no in-car call in the lower car (S1102 / NO), the motor control unit 122 determines that correction is unnecessary (S1106), and ends the process.

  If the result of the determination in S1102 is that there is an in-car call in the lower car (S1102 / YES), then the electric motor control unit 122, based on the information input from the operation signal acquisition unit 123, the hall in the lower floor destination floor It is determined whether or not the call button is pressed, that is, whether or not there is a hall call for the lower car (S1103).

  As a result of the determination in S1103, if there is a hall call for the lower car (S1103 / YES), the motor control unit 122 then determines the hall in the destination floor of the upper car based on the information input from the operation signal acquisition unit 123. It is determined whether or not the call button is pressed, that is, whether or not there is an upper car hall call (S1104). If there is a hall call for the upper car (S1104 / YES), the motor control unit 122 determines that the correction pattern is the pattern D (S1105), and ends the process. On the other hand, if there is no hall call for the upper car (S1104 / NO), the motor control unit 122 determines that correction is unnecessary (S1106), and ends the process.

  If the result of the determination in S1103 is that there is no hall call for the lower car (S1103 / NO), next, the motor control unit 122 determines whether there is a hall call for the upper car as in S1104 (S1107). ). As a result of the determination in S1107, if there is an upper car hall call (S1107 / YES), the motor control unit 122 determines that the correction is appropriate instead of correcting in advance (S1108), and ends the process. If there is no hall call for the upper car as a result of the determination in S1107 (S1107 / NO), the electric motor control unit 122 determines that the correction pattern is pattern A (S1109), and ends the process.

  By such processing, the determination processing of the car interval adjustment pattern according to the present embodiment is completed. Note that the processing illustrated in FIGS. 10 and 11 is an example, and the car interval adjustment pattern can be determined according to other processing. Moreover, the motor control part 122 has memorize | stored the table containing information as shown in FIG.5 and FIG.6, and it shows in FIG. 5 by using the information input from the operation signal acquisition part 123 and the load amount detection part 124 as a search key. It is also possible to determine which correction pattern is applied by narrowing down the information.

  As described above, according to the present embodiment, when the control device 12 determines that the electric motor 10 is stopped, it is provided in the upper and lower cars, not the position detection mechanism provided in the outer car frame 1 as in the prior art. Since the determination is made based on the detection signal of the car position detector 7, the landing accuracy of either the upper or lower car can be increased according to the operating condition of the elevator. Therefore, it is possible to provide a car deck variable double deck elevator with higher landing accuracy.

  In the above embodiment, as described with reference to FIG. 5, the determination of the load amount is made in two steps, that is, whether the load amount is larger or smaller than a predetermined threshold value. You may judge by the above. In this case, as the adjustment amount of the car interval described as “+ α” or “−α” in FIG. 6, it is preferable to set a plurality of adjustment amounts according to the loading amount.

  Moreover, in the said embodiment, the case where it is judged whether landing control is performed with reference to the signal of the car position detector 7 provided in any of the upper and lower cars based on the table as shown in FIG. 5 is taken as an example. explained. In addition, for example, in the operation using only one of the upper and lower cars, the landing accuracy of the unused car is unnecessary, so that the landing is made with reference to the signal of the car position detector 7 provided in the used car. It is preferable to perform control.
