2. Description of the Related Art A double-deck elevator is a special elevator that has an upper car and a lower car, which are two-story elevators, and both cars are simultaneously active on the adjacent two-story floors. However, it is inevitable that there will be floors where the distance between the floors of both cars and the distance between the floors of both cars scheduled to stop are not equal due to construction errors of the building. For this reason, a step is generated between the car floor and the landing floor, and if this step is large, there is a risk that the passenger will stumble upon getting on and off the vehicle. Therefore, it is desirable to make this step as small as possible.

Therefore, for example, Japanese Patent Laid-Open No. 4-223985.
According to the publication, at least one of the cars is supported by a hydraulic drive mechanism, and the space between the cars is adjusted by controlling the hydraulic drive mechanism according to the floor distance of the second floor when the car is landed. Proposed.

[0004]

In the conventional double-deck elevator as described above, at least one of the cars is moved up and down to match the floor distance, so that the structure becomes complicated and expensive. There is a problem that becomes.

The present invention has been made in order to solve the above-mentioned problems, and a double deck capable of reducing the stumbling at the time of getting on and off due to the step between the car floor and the landing floor without making the both cars into a complicated structure. It is an object to provide an elevator driving device.

(8) is a pulse counter which outputs a car position signal (8a) by adding and subtracting the pulse generated from the pulse generator (7) according to the traveling direction of the elevator (1), and (9) is Car position signal (8a), position signal (10a) described later, door open / closed state signal
(11Aa) (11Ba) and car call signals (12Aa) (12Ba) are input, and a speed command value (9a) is output to the speed control device (6).

A position detector (10) is provided on the elevator (1) with the lower car (1B) as a reference, and is related to the plates P _B , P _{1 to} P _n installed at each floor position of the hoistway. Position signal
Output (10a). (11A) and (11B) are the upper car (1A) and the lower car

This embodiment (the same applies to the following embodiments)
Then, since the control is based on the lower car (1B), for example, the stop position represents the position where the floor of the lower car (1B) stops (it is clear that the upper car (1A) may be the reference. is there). Accordingly, the plates P _{1 to} P _n detect the position when the step between the floor of the lower car (1B) and the floor of each floor becomes zero.
The position signal (10a) is output from.

In FIG. 2, reference numeral (9) is a speed command generator composed of a microcomputer, which includes a CPU (9A) and an RO.
It has an M (9B), a RAM (9C), an input device (9D) and an output device (9E). The input device (9D) has a car position signal (8a) and a position signal (1
0a), door open / close state signal (11Aa) (11Ba) and car call signal (12
Aa) (12Ba) is input, and the speed command value (9
a) is output.

Next, the operation of this embodiment will be described with reference to FIGS. The programs of these flowcharts are stored in the ROM (9B) of the speed command generator (9) (the same applies to the following embodiments). First, the lower car length measuring operation according to FIG. 3 will be described. This is done before the normal operation of the elevator.

First, in step (21), the lifting and lowering body (1) is moved to stop the upper car (1A) at the lowest floor so that the upper car (1A) floor and the landing floor are aligned with each other, and step (22) Then, the car position signal (8a) at that time is stored in the RAM (9C). Next, move the elevator (1) again and stop the lower car (1B) at the bottom floor,
Align the lower car (1B) floor with the landing floor, and perform the same step (24).
The car position signal (8a) is input and stored in the RAM (9C).
Then, in step (25), if the difference between the floor positions obtained above is calculated as in equation (1), this becomes the lower car length L. The measured lower basket length L is stored in the RAM (9C). The steps (21) to (25) constitute a lower car length measuring means. L = (Car position when lower car (1B) is on the lowest floor)-(Car position when upper car (1A) is on the lowest floor) ・ ・ ・ (1)

The lower basket length L was measured on the bottom floor,
Install the plate Pn on the top floor so that the position signal (10a) is generated when the step between the bottom car (1B) floor and the floor on the top floor becomes zero, and plate Pn-1 on the top car (1A) floor When there is no step between the floor on the front floor and the first floor on the top floor, the position signal
It is also possible to attach and measure so that (10a) is generated. By doing so, the difference between the car position when the lower car (1B) is on the top floor and the car position when the upper car (1A) is on the top floor is the lower car length L. Also on the middle floor,
Similarly, the bottom basket length L can be measured. In addition, lower basket length L
Was measured by moving the lifting body (1), but a value actually measured in advance may be used.

Next, the stop position setting operation according to FIG. 4 will be described. This is executed when the floor to be stopped is determined by the car call or the hall call. First,
From the RAM (9C) in which the floor position is stored in advance in step (31) (inter-floor distance calculation means), the floor where the upper car (1A) and the lower car (1B) should stop, that is, the floor to be stopped Each floor position is read, and the scheduled stop floor distance FM is calculated as in equation (2). FM = (upper car (1A) scheduled floor stop floor position)-(lower car (1B)
(Scheduled stop floor position) (2) The floor distances of all floors may be stored in the ROM (9B), and the scheduled stop floor distance FM may be extracted from this.

Then, in step (32), the lower car length L is compared with the planned stop floor distance FM. When both are equal,
In step (33), the floor position of the floor to be stopped by the lower car (1B) is set as the stop position ST. If not equal to the expression in step (34)
As in (3), the position where the upper car (1A) and the lower car (1B) have the same step difference from the boarding floor, that is, half of the difference between the lower car length L and the planned floor distance FM , The lower car (1B) is the stop position ST which is the position subtracted from the floor position of the scheduled stop floor. The steps (32) to (34) constitute a stop position calculating means. ST = (Lower car (1B) floor to be stopped)-(Lower car length L
-Scheduled stop floor distance FM) / 2 ... (3)

Then, in step (35), the stop position S obtained in step (33) or step (34) is calculated from the current car position.
Calculate the speed command value (9a) with T as the target position, and
At (36), it outputs to the speed control device (6) via the output device (9E). Steps (35) and (36) are repeated until the lifting / lowering body (1) reaches the stop position ST in step (37). In addition, step
The means for calculating the speed command value (9a) of (35) is, for example, Japanese Patent Laid-Open No.
Since it is shown in Japanese Patent Publication No. 9678 and is well known, detailed description thereof will be omitted.

In FIG. 5 (a), when the length L of the lower car is equal to the distance FM between the floors to be stopped, the stop position ST is set to the floor position of the floor DF to be stopped at the lower position in step (33). Basket (1A)
Floor and lower car (1B) Indicates the positional relationship between the floor and the landing floor. There are no steps on both the upper car (1A) and lower car (1B) (UF is the floor where the upper car is scheduled to stop). FIG. 5B shows a case where the stop position ST is set so that the steps of both the upper car (1A) and the lower car (1B) are averaged in the step (34). By thus averaging the steps, the risk of tripping or the like when getting on or off can be reduced.

Example 2. 6 and 7 are views showing an embodiment of the third, fourth and seventh inventions of the present invention, FIG. 6 is a stop position setting operation flowchart, and FIG. 7 is an explanatory view of a positional relationship between a car floor and a landing floor. Is. 1 to 3 are also used in the second embodiment.

When the elevator (1) travels and arrives at the scheduled stop floor, the stop position setting operation shown in FIG. 6 is executed. First, in step (41), the planned inter-floor distance FM is calculated in the same manner as in step (31) in FIG. 4, and in step (42), as in step (32) in FIG. The planned inter-floor distance FM is compared.

If both are the same, step (33) in FIG.
As indicated by, the process is terminated because there is no step between the car floor and the landing floor, so the process ends. If they are not equal, proceed to step (43). In step (43), the door open / closed state signal (1
From 1Aa) (11Ba), determine whether both cars (1A) (1B) are closed. When the door is closed, there are no people getting on and off, so do nothing. If both cars (1A) and (1B) are not closed, proceed to step (44) to determine whether both cars (1A) and (1B) are open.

[0037] When both cars (1A) and (1B) are open together, in step (45) the stop position is the position where the level difference between the car floor of both cars (1A) and (1B) and the floor to be stopped is equal. ST (stop position ST is calculated by equation (3)). If step (44) determines that at least one car is closed, step (46) determines if only the upper car (1A) is closed and only the upper car (1A) is closed. If so, the stop position ST is set to the floor position of the floor to be stopped in the lower car (1B) in step (47).

On the contrary, when it is determined in step (46) that only the lower car (1B) is closed, the upper car (1A) floor coincides with the upper car (1A) scheduled stop floor in step (48). The position where
Calculated in (4) and set as the stop position ST. Stop position ST = (lower car planned floor stop floor position) + (planned floor distance FM-lower car length L) (4) That is, steps (43) to (48) are closed. This is an operation in which the stop position ST is set to a position where the step between the car floor of the car that is open and the floor to be stopped becomes zero, ignoring the car. In addition, steps (43) (44) (46), door opening and closing detection means,
Steps (45) (47) (48) constitute stop position calculating means.

In step (49), steps (45) (47) (48)
It is judged whether the lifting / lowering body (1) is stopped at the stop position set by. If it is stopped, the process returns to step (43), and step
Repeat (43) to (49). If not stopped, step
The elevator (1) is restarted at (50) and stopped at the stop position ST. These steps (43) to (50) are repeated until the next driving command comes.

In FIG. 7A, only the upper car (1A) is closed, and the two cars (1A) when the process of step (47) is executed.
(1B) Shows the positional relationship between the floor and the landing floor. Further, FIG. 7B shows the case where only the lower car (1B) is closed and the process of step (48) is executed. In this way, by ignoring the car that is closed, it is possible to eliminate the step of the car that is open.

Example 3. 8 and 9 show the fifth embodiment of the present invention.
8 is a diagram showing an embodiment of the seventh invention, FIG. 8 is a stop position setting operation flowchart, and corresponds to a chain line portion in FIG.
FIG. 9 is an explanatory diagram of the positional relationship between the car floor and the landing floor. In addition,
1 to 3 are common to the third embodiment.

When it is determined in step (44) (door opening / closing detection means) in FIG. 6 that both cars (1A) and (1B) are open, step
(61) (Car call detection means) Car call signal (12Aa) (12Ba)
From both cars (1A) (1B) to determine whether there is a car call, and if both cars (1A) (1B) have a car call, in step (62) the car of both cars (1A) (1B) The position where the step difference between the floor and the floor to be stopped is equal is defined as the stop position ST (the stop position ST is calculated by the equation (3)). If it is determined in step (61) that at least one of the cars is not called, the process proceeds to step (63).

In step (63), it is judged whether the lower car length L is smaller than the planned floor distance FM between stops, and if smaller, it is judged in step (64) whether the upper car (1A) has no car call. If there is no car in the upper car (1A), go to the lower car in step (65).
(1B) The stop position ST is the floor position of the planned stop floor. If there is a car call in the upper car (1A), proceed to step (62).

When it is determined in step (63) that the length L of the lower car is larger than the planned inter-floor distance FM, the step (66) determines whether or not the lower car (1B) is called by a car. Lower basket (1B)
If there is no car call, a position where the floor of the upper car (1A) coincides with the floor of the landing is calculated by the formula (4) in step (67), and is set as the stop position ST. If there is no car in the lower car (1B), proceed to step (62). It should be noted that steps (62) to (66) constitute stop position detecting means.

That is, a car without a car call is only a person who gets in from the hall, so if the car floor is located lower than the floor, it will not trip over when getting on the car. Therefore, for cars without a car call, set the stop position ST so that the car floor will not be higher than the landing floor, and for cars with a car call as much as possible, the step between the car floor and the landing floor will be zero. To do.

9 (a) and 9 (b) show the relationship between the lower car length L <the distance FM between planned floors to be stopped, and FIGS. 9 (c) and 9 (d), conversely, the lower car length L> the planned floor to be stopped. The case where there is a relationship of the distance FM is shown. FIG. 9B shows the stop position ST set in step (65).
It was when I stopped. Similarly in FIG. 9D, step (67)
This is when the vehicle has stopped at the stop position ST set by. Figure 9
In FIG. 9 (b), the upper car without car call (1A) and the lower car without car call (1B) in FIG. 9 (d) are prevented from being higher than the landing floor.

In FIGS. 9 (a) and 9 (c), when the elevator body (1) is moved so that the car floor without a car call is higher than the landing floor, the other car floor moves away from the landing floor and the step is large. Since it will be, both steps (1A) according to step (62)
The stop position ST is the position where the level difference between the car floor and the landing floor in (1B) is equal.

[0048]

As described above, according to the first aspect of the present invention, the difference between the floors of both cars and the floor to be stopped is determined from the distance between the floors of the cars and the floor distance of the floors to be stopped of both cars. Since the cars are stopped at the same position, the steps are averaged by both cars, which has the effect of reducing tripping when getting on and off.

In the second aspect of the invention, the plate on each floor installed in the hoistway is detected to measure the distance between the floors of both cars, and the inter-floor distance between the floors where both cars are scheduled to stop is calculated. If the distances are equal, it is stopped at the floor position of the planned floor, and if they are not equal, the car is stopped at the same level difference between the floors and the planned floors. Is measured by the movement of the lifting body, and it is possible to set a stop position that matches the actual building, does not require a complicated circuit, and has the effect of being inexpensively constructed.

Further, in the third and fourth inventions, when either of the cars is closed, the car floor of the car that is open and the step difference between the car floor and the floor to be stopped become zero. Since the door is stopped, there is no step in the door-opening door where passengers get on and off, and it is possible to prevent tripping when getting on and off and to improve safety.

In the fifth aspect of the invention, if both cars are open, and at least one car has no car call, the floor of the car will not be higher than the floor to be stopped. Therefore, the floor of the car where only passengers are present does not become higher than the floor of the landing hall, and there is an effect of preventing tripping when riding.

In the sixth aspect of the invention, when both cars are open and both cars have a car call, or at least one car has no car call and the car floor of this car is stopped. If there is a step in the other car when stopped at a position that is not higher than the planned floor, the steps of both cars are made equal, so the steps of the cars with passengers are averaged and It has the effect of preventing tripping.

Further, in the seventh invention, when the lifting / lowering body is not stopped at the calculated stop position, the lifting / lowering body is restarted and moved to the stop position. It has the effect of stopping at various stop positions.
