[0005]
[Problems to be solved by the invention]
A panel for opening and closing the entrance is provided using the conventional opening as the entrance for the vehicle. In order to reduce the output capacity of the guard motor that raises the panel, the weight is suspended so that the weight of the weight close to the weight of the panel moves up and down to a position adjacent to the entrance.
[0006]
However, when the left / right opening position adjacent to the boarding port is the second boarding port, the weight cannot be moved in and out, so that the weight is eliminated and the winding drum is directly wound. In this configuration, if the capacity of the guard motor is not large, winding and rewinding cannot be performed, and a large guard motor is employed. For this reason, the geared motor is expensive, requires a large installation place, and spends money on the amount of electricity.
[0007]
In the present invention, the weight is not reduced by suspending the weight on the geared motor as in the prior art, but the additional power that can mechanically store and release the rotational power in the geared motor by using a wound motor that is wound up by a winding drum. Means are provided. With this configuration, a small gear motor with a small capacity can be stored and discharged by the additional power means, which eliminates the need for weight, saves installation space, and saves electricity. .
[0008]
When the ascending / descending object descends, the accumulation means is rotated by the weight of the ascending / descending object to store the output. When raising an elevating object, a geared motor with built-in additional power that can add the accumulated power to the output of the geared motor by discharging the accumulated output by the additional power means.
[0009]

The geared motor is formed in the second case that attached to the first casing, and a second output shaft is in said second case to rotate in conjunction with the first output shaft through the gear device, the second Additional power means for storing or releasing power is provided by rotation of the output shaft .
The power of the additional power means is such that the weight of the first output shaft moving down the lifting object in the forward rotation direction accumulates power in the second output shaft, and the second output is increased when the lifting object in the reverse rotation direction moves up. The power accumulated in the shaft is released.
The rotation of the additional power means is configured to shift the rotation from the second output shaft via the gear device of the first case and transmit the rotation to the first output shaft .
[0012]
According to the first aspect of the present invention, the weight for lowering the lifting object is accumulated on the output shaft of the geared motor, and the accumulated power is released when the lifting object is raised, thereby increasing the driving force of the output shaft. As a result, the capacity of the motor can be reduced, the installation location can be narrowed, the amount of electricity can be reduced, and weights can be made unnecessary. Can be expanded and adopted.
[0013]
The first output shaft, as a positive direction of rotation rewind, by storing power in the first output shaft to the second output shaft, not to a plurality of mechanisms, a power discard rewind heavy, Play Stored as energy.
[0014]
Effect when lowering the elevating product was suspended to the output shaft, a power to rotate the output shaft by the weight of the elevator was joined by power of the motor, since it is surplus power, capable of storing the power Therefore, it is safe and smooth to slow down the descending speed of the lift.
[0015]
Springs power, it is easily possible inexpensive act to accumulate, can be increased even accumulation by increasing the travel distance by the coil spring. Rotation of the additional power means, since the rotational torque of the first output shaft through the gear device, it is possible to accumulate in small, has the effect of possible spring small, handling of the spring can be easily. When releasing, the second output shaft has a function of shifting the torque of the second output shaft by the speed reduction mechanism to increase the torque and adding the power to the first output shaft, so that the power can be transmitted smoothly.

A pulley 10 is rotatably mounted on the upper side of the guide rail 9 to turn the wire 12 in the direction of the winding drum 7.
[0020]
The winding drum 7 is driven and rotated by the guard motor 3 and has an operation panel 8 in the vicinity of the opening 4. The operation panel 8 includes an up button, a stop button, and a down button. The ascending button or the descending button can stop the panel 2 when the panel 2 is raised by opening the opening 4 to be in a stopped state, and the panel 2 is lowered from the opened state.
[0021]
Opening and closing of the opening 4 is opened when the transporting machine arranged at the boarding place is stopped, and is closed so as to block traffic for safety when entering the traveling operation. The adjacent opening 4a is a section on the floor surface parallel to the ground surface GL, where the vehicle can be moved forward and backward to enter and exit, and is always in an open state and is not provided with a blocking panel.
[0022]
FIG. 2 shows a geared motor 3 for driving and rotating the winding drum 7. The first case 13 is an entire frame, the first output shaft 21 is projected on one side, and the motor 15 is mounted on the other side. The first case 13 is a gear case made of an aluminum outer frame, hollowed inside, and meshed with a plurality of gears and filled with oil. The lower part is used as a base for mounting and mounting holes are provided at four corners. I have.
[0023]
The mounting holes of the base allow the guard motor 3 to be fixed to the ceiling portion 6 with bolts. The second case 14 is formed by bending a plate material in a cylindrical shape provided adjacent to the first case 13, and a second output shaft 22 is attached to the frame inside and a winding spring 26 is provided around the second case 14. One end of the winding spring 26 is fixed to a plate 27 slidably interposed on the second output shaft 22, and the output gear 24 fixed to the second output shaft 22 is driven and rotated .
[0024]
FIG. 3 illustrates the inside of the geared motor 3. The motor 15 includes a motor 15 that transmits driving rotation to the first output shaft 21. The motor 15 has a motor shaft that rotates at high speed, and the number of teeth provided on the motor shaft. There is a first gear 18 having a large number of teeth meshing with the pinion 16 having a small number. The first gear 18 is fixed to the shaft 17 to reduce the rotational speed of the pinion 16.
[0025]
A second gear 19 and an output gear 23 are fixed to the shaft 17 in addition to the first gear 18. The second gear 19 has a small number of teeth, and further decelerates by engaging with the third gear 20 having a large number of teeth.

[0026]
The output gear 23 is connected by a belt 25 to an output gear 24 that is rotatably attached to the second output shaft 22 from the output gear 23 that is fitted to the shaft 17 of the gear device G. The output gear 24 supports one end of the winding spring 26 and rotates in a direction in which the winding spring 26 is wound up by the rotation of the output gear 23. The coil spring 26 can be discharged in the reverse direction by accumulating the rotation of the output gear 24.
[0027]
The rotation in the accumulation direction is performed when the panel 2 of the opening 4 descends in the closing direction from the upper position in the open state.
The winding spring 26 suppresses the descending speed of the panel 2 by the load to be wound up and works in the direction in which the weight of the panel 2 is wound up. Therefore, the winding spring 26 can be easily wound up by the motor 15 having a small capacity.

The rotational torque of the winding spring 26 is amplified by the third gear 20, and the torque of the motor 15 is further multiplied by the speed ratio by the gear device G to the third gear 20, and the torque of the motor 15 and the rotational torque of the winding spring 26 are combined. In addition, the winding drum 7 fitted to the first output shaft 21 is rotated.
[0029]
(Description of operation)
The opening / closing device 1 will be described as a device arranged to be opened and closed by being raised and lowered at the entrance of a boarding place of a mechanical parking tower. The entrance / exit of the boarding area is provided with an opening 4 for entering the multi-story parking tower so that the vehicle can enter and exit, and the rollers 11 are pivotally attached to the vertical positions on both sides of the panel 2 as the opening / closing device 1. Yes, it rolls up and down in the guide rail 9.
[0030]
The guide rail 9 includes a guide rail 9 that guides the panel 2 that moves up and down vertically. A rotatable pulley 10 is rotatably attached to the upper end of the guide rail 9, and a wire 12 wound around the pulley 10 suspends the panel 2 vertically. The panel 2 moves up and down by winding and unwinding the wire 12 to open and close the opening 4.
[0031]
In the opening 4, the winding drum 7 that is rotated by the guard motor 3 winds the wire 12 and raises the panel 2. At the raised position of the panel 2, the guard motor 3 is stopped in a state in which the diameter of the winding spring 26 incorporated in the second case is expanded.
[0032]
When closing the opening 4, the guard motor 3 is reversely rotated so that the panel 2 is lowered downward from the raised position. Since the guard motor 3 is in a state in which the wire 12 is wound around the winding drum 7 and the panel 2 is suspended, the weight of the panel 2 is applied to the wire 12, and the winding drum 7 is rotated by the action of rotating the winding drum 7. By releasing the brake, the power source is not required and the panel 2 can be lowered by its own weight. A switch (not shown) is provided at the descending stop position and the ascending stop position, and the guard motor 3 is braked to stop the rotation of the winding drum 7.
[0033]
When the wire 12 is pulled out by the weight of the panel 2 and the winding drum 7 is rotated in the reverse direction, the second output shaft 22 is rotated by the reverse rotation of the winding drum 7 so that the second gear 20 and the second gear 2 are moved downward. Depending on the speed ratio of the gear 19, the second output shaft 22 is rotated at a higher rotation than the reverse rotation of the winding drum 7. When the second output shaft 22 rotates, the winding spring 26 can be reduced in diameter to accumulate power. Due to this accumulation, the winding drum 7 becomes resistant to reverse rotation and reduces the descending speed of the panel 2, which is effective in safety.
[0034]
The panel 2 is lifted by rotating the third gear 20 by rotating the third gear 20 by transmitting the driving force accumulated when the panel 2 is lowered to the second gear 19 in addition to the rotation of the guard motor 3. The take-up drum 7 is rotated forward to wind up the wire 12 and raise the panel 2.
[0035]
To adjust the torque of the winding spring 26, one end of the winding spring 26 is attached to an output gear 23 rotatably provided on one of the second output shafts 22 fixed to the first case 13, and the other is engaged with the spline 28. The plate 27 having the joint portion is fitted and the other end of the winding spring 26 is attached. The adjustment by the plate 27 varies depending on the weight of the panel 2, but the panel 2 is faced upward so that no load is applied when the opening 4 is opened.
[0036]
The plate 27 is removed from the spline 28, and the winding spring 26 is rotated in the direction of reducing the diameter, and the plate 27 is engaged with the spline 28 at a position where the rising torque is generated.
When the panel 2 is lowered, the weight of the panel rotates the output gear 24 to reduce the diameter of the winding spring 26 and accumulate the rising torque. At this time, if the rising torque is small, the plate 27 adjusts by rotating the winding spring 26 in the diameter reducing direction again as described in the adjustment method of the plate 27.
[0037]
【The invention's effect】
According to the first aspect of the present invention, the driving force of the geared motor can be accumulated and discharged, and the size can be reduced and the weight can be eliminated, so that the installation place can be saved. There is.
When the temperature descending article is lowered, so rotate the first output shaft by the weight of the lifting goods, by storing the power to the additional power means, it is possible to slow down the lowering speed, accessory devices such as an inverter brake There is also an effect that it can operate safely without relying on.
Furthermore, the power accumulated during the descent of the elevating articles, and released upon increase of the lifting goods, there is also an effect of the capacity of the motor small because it increases the hoisting force.
And, adopting the Makibane Since the spring diameter can accumulate and release by causing Chijimi拡can be miniaturized, the rotation of the winding drum is larger sometimes rewind's resistance you lower the elevator article since slow the descent speed and is safe, when rolling up can increase the driving force, an effect of performing the lifting operation smoothly.
