[0002]

2. Description of the Related Art In recent years, as land prices have risen and residential land has decreased, the number of buildings such as condominiums utilizing mountain slopes has increased, and the demand for oblique elevators as a means of transportation on sloping ground has increased accordingly. . Further, in such an elevator, it is required to speed up / down the speed and improve riding comfort. In particular, it is necessary to increase the acceleration at the time of departure and stop in order to increase the lifting speed, but on the contrary, the horizontal inertial force exerted on the passengers becomes large and the start and stop may be added. When decelerating, it gives passengers discomfort.

Therefore, in the conventional art, it is important to eliminate the discomfort caused by the horizontal inertial force peculiar to the start and stop of the oblique elevator rather than the speed increase, and the acceleration is reduced to the extent that the discomfort is not felt. I was driving an oblique elevator.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. First, the principle of the present invention will be described with reference to FIGS.

FIG. 1 is a schematic diagram of a skew elevator according to the present invention.

In FIG. 1, an elevator car 1 is slanted up and down via a rope 4 by the rotation of a hoisting sheave 3 that receives the rotational force of a hoisting machine 2 provided in a machine room (not shown). It is like this. Wheels 6 and 7 are attached to a car 1 connected to one end of the rope 4 and a balancing weight 5 provided to the other end, respectively, so that they can move along rails 8 and 9 provided in parallel with the elevation angle. It has become.

The car floor 10 of the car 1 can be tilted by a hinge 11 provided at an end of the car floor 10. Then, as a tilting operation means, a hydraulic unit 12 is provided below the car floor 10, and another hydraulic unit 12 is provided below the car floor 10, that is, a tilt angle control device for controlling the tilt angle of the car floor 10. An angle sensor 14 for detecting the inclination angle of the car floor 10 and a load sensor 15 for detecting the load inside the car are provided. Further, the wheel 6 is provided with a pulse generator 16 that generates a pulse in synchronization with the rotation of the wheel 6.

Next, the configuration of the tilt angle control device 13 will be described with reference to FIG.

In FIG. 2, the inclination angle control device 13 calculates the acceleration of the car 1 based on the pulse signal from the pulse generator 16 and the car based on the angle detection signal from the angle sensor 14. An angle detector 18 for detecting the angle of the floor 10, a load detector 19 for detecting the load inside the car based on the load detection signal from the load sensor 15,
Based on the acceleration signal from the acceleration calculator 17, the car floor 1
An angle calculator 20 that calculates a command value of a tilt angle of 0, a calculator 21 that calculates a difference between an angle signal from the angle detector 18 and an angle command signal from the angle calculator 20, and a calculator 21.
From the load detector 19 and the load signal from the load detector 19 to calculate the command value of the current supplied to the solenoid valve for adjusting the supplied oil amount provided in the hydraulic unit 12. . Here, the hydraulic unit 1
Although not shown, 2 is a hydraulic jack using a cylinder and a piston, and the amount of oil supplied to the cylinder is adjusted by a solenoid valve.

Next, the relationship between the acceleration of the car 1 and the inclination angle of the car floor 10 will be described based on the mechanical model diagrams of FIGS. 3 to 5.

Passengers 23 in the car 1 at the time of departure of the elevator
As shown in FIG. 3, when the inertial acceleration at this time is a and the mass of the passenger is m, the force acting on the Three
It becomes 5. In contrast, when the elevator is stopped, the car 1
The force acting on the passenger 23 inside is the resultant force of the inertia force ma in the traveling direction and the mg of gravity 33 in the vertical direction. It is felt that only the resultant force 35 acts on the passengers 23 in the car 1 during the acceleration / deceleration operation of the elevator. Then, the acting direction and the magnitude of the resultant force 35 at this time can be expressed as shown in FIG. 4 by using the object 30 equivalent to the passenger 23.

FIG. 4A shows a passenger 23 in the car 1 of FIG.
The force acting on the vehicle is represented by being replaced with the object 30, and in FIG. 4B, the inertial force 31 is decomposed into a horizontal component and a vertical component in order to obtain a resultant force 35 acting on the passenger 23. In FIG. 4B, 37 is the horizontal component m of the inertial force.
acos θ, and 39 is the sum of the vertical component masin θ of the inertial force and mg of gravity 33. However, θ is the slope inclination angle of the oblique elevator. The cause of the passenger 23 in the car 1 tending to collapse or tripping when the elevator starts and stops is due to the horizontal component 37 of the inertial force. In order to cancel this component, the car floor 10 may be inclined by the angle φ so that the resultant force 35 becomes equal to the vertical drag force of the car floor 10. A schematic representation of this is shown in FIG. Here, from FIG. 4B, the magnitude of the resultant force 35 can be expressed by Expression (1), and the direction φ can be expressed by Expression (2).

| P | = m × {(acos θ) ² + (g + asin θ) ² } ^1/2 (1) φ = tan ⁻¹ (acos θ) / (g + asin θ) (2) For example, General acceleration of line elevator a = 0.4m
/ S ² , gravitational acceleration g = 9.8 m / S ² , and when the elevator tilt angle θ is 30 °, the car floor 23 has an angle φ = 2.0.
^You can tilt it to ^* .

As shown in FIG. 5, by tilting the car floor 10 so that the resultant force 35 acting on the passengers 23 in the car 1 when the elevator starts and stops becomes equal to the vertical drag force of the car floor 10, 23 has inertial force 31 and gravity 3
3 acts vertically on the car floor 10 and feels as if the horizontal component 37 of the inertial force were cancelled.

Next, the operation of the tilt control device 13 will be described with reference to FIGS. 6 and 7.

First, the operation of the acceleration calculator 17 will be described. The car 1 moves up and down in a trapezoidal speed pattern 51 as shown in FIG.
Has a pattern as shown by the solid line in FIG. While the car 1 is traveling, the pulse generator 16 that converts the rotation of the wheels 6 of the car 1 into a pulse always sends a pulse signal to the acceleration calculator 17, and the pulse signal is sent to the acceleration calculator 17
The pulse counter of the internal memory is incremented each time is received. The acceleration calculator 17 checks this pulse counter at regular time intervals (for example, 10 ms intervals),
Acceleration of car 1 and car 1 depending on the state when checked
The elapsed time since the start of movement is output.

Here, the processing of the acceleration calculator 17 from the time the wheel 6 starts to rotate to the constant speed rotation until the rotation stops will be described in detail with reference to the flowchart of FIG.

First, the acceleration calculator 17 determines whether or not the wheels 6 are stopped, and if the pulse counter is not 0, recognizes that the wheels are currently rotating (S10), and S
When it is determined that the car 1 is in operation at 10,
It is determined whether or not the pulse counter in the previous processing of S10 is 0, that is, whether or not the wheels 6 were stopped in the previous processing (S11). When it is determined in S11 that the pulse counter at the time of the previous processing is 0, the timer is started (S12), and when it is determined that the pulse counter is not 0 and the car 1 is in operation, the time T _M elapses. It is determined whether or not. That is, the process after S13 is T
Processing will be performed at _M time intervals. Where S13
At, it is determined that has elapsed T _M times, the difference between the current pulse counter and the previous pulse counter, calculates the number of pulses at T _M times (S14), then the number of pulses T
_The car acceleration is differentiated twice in _M time (S1
5). When the car acceleration is calculated in S15, the value is output to the angle calculator 20 and the elapsed time from the start of the car is output (S16). And for a certain period of time T _L
If the pulse counter has changed within the range, the current pulse counter is set to the previous pulse counter (S18), and if there is no change, the current and previous pulse counters are reset (S19).

Next, the operation of the tilt angle control device 13 will be described.

When the current car acceleration is input from the acceleration calculator 17, the angle calculator 16 calculates an appropriate inclination angle φ of the car floor 10 based on this acceleration according to the equation (2). Output to the calculator 21. The calculator 21 is
When the data of the target value of the inclination angle of the car floor 10 is input from the angle calculator 16, it is compared with the current inclination angle data from the angle detector 18, and the difference is output to the controller 22. When the controller 22 receives the difference data from the inclination angle target value from the calculator 21, the controller 22 adjusts the supply current to the solenoid valve so that the difference becomes 0, and the load detector 1
Determine the supply current based on the load signal from 9.

Therefore, according to the principle of the present invention, by inclining the car floor 10 by an optimum angle so as to cancel out the inertial force generated when the car starts and stops, the acceleration and deceleration such as the start and stop of the elevator as in the conventional case. It is possible to ride comfortably without feeling the discomfort due to the inertial force that is sometimes given to passengers.

Further, since the acceleration of departure and stop can be increased, the speed of the elevator can be increased and the efficiency of operation can be improved.

Further, since the acceleration of the car 1 is taken directly from the wheels, the entire apparatus can be housed in the car, and the size can be reduced.

The description is omitted here because it is the same as the content described by.

Here, the processing of the acceleration compensator 17b will be described with reference to the flowchart of FIG.

First, the acceleration compensator 17b calculates a difference ad between the hoisting acceleration calculated by the acceleration calculator 17a and the acceleration of the car 1 calculated by the acceleration calculator 17 (S2).
0). This difference ad is caused by slipping of the car wheel 6. When this difference ad exceeds a certain allowable value (S
21), the car acceleration is corrected (S22). As a method of correcting the car acceleration, a method of adding 1/2 of the difference ad to the acceleration of the car 1 calculated by the acceleration calculator 17 as a correction value is used.

If the difference ad is less than the allowable value in S21, the acceleration of the car 1 is not corrected and the acceleration of the car 1 calculated by the acceleration calculator 17 is used as the input signal of the angle calculator 20. .

Therefore, according to the first embodiment described above, it is possible to correct the error in the acceleration of the car 1 caused by the slip of the car wheels 6 and the like accompanying the increase in the acceleration of starting and stopping. It is possible to completely eliminate the discomfort caused by the inertial force applied to the passengers during acceleration / deceleration such as the start and stop of the elevator, and it is possible to ride comfortably.
