The bearing 6 provided on the upper frame 2 can support the upper hinge shaft 4 in the vertical direction and at an angle inclined with respect to the vertical direction. When the upper hinge shaft 4 is inserted into the bearing 6 in order to install each panel 1 between the upper frame 2 and the lower frame 3, the hinge shaft 4 can be inserted into the bearing 6 from obliquely below.
[0018]
Therefore, when each panel 1 is installed between the upper frame 2 and the lower frame 3, the installation work can be easily performed.
An interlocking shaft 8 is rotatably supported in the upper frame 2, and one end of the interlocking shaft 8 is connected to an output shaft of an opening / closing motor 9. The interlocking shaft 8 is connected to the upper hinge shaft 4 via a gear box 10 and a torque limiter 11 above each panel 1.
[0019]
When the interlocking shaft 8 is rotated by the operation of the opening / closing motor 9, the upper hinge shaft 4 is rotated via the gear box 10 and the torque limiter 11, and the panel 1 is rotated with the rotation of the upper hinge shaft 4. Rotated.
[0020]
The detailed configurations of the gear box 10 and the torque limiter 11 will be described with reference to FIGS. 2 to 4. The drive side and driven side bevel gears 12 a and 12 b are rotatably supported in the gear box 10, and the interlocking shaft 8 is It is fitted into the drive-side bevel gear 12a.
[0021]
Accordingly, when the interlocking shaft 8 is rotated, the driven bevel gear 12b is rotated via the driving bevel gear 12a.
An output shaft 13 is fitted to the center of the driven bevel gear 12b, and the output shaft 13 rotates integrally with the driven bevel gear 12b.
[0022]
The torque limiter 11 is interposed between the output shaft 13 and the upper hinge shaft 4. As shown in FIG. 4, the torque limiter 11 has a lining 15 sandwiched between an upper sandwiching plate 14a and a lower sandwiching plate 14b made of iron, and is inserted around the two sandwiching plates 14a and 14b. By adjusting the urging force of the coil spring 17 with the bolt 16, the frictional force between the holding plates 14a, 14b and the lining 15 is set to a predetermined value.
[0023]
The lower end of the output shaft 13 of the driven bevel gear 12b is fitted to the center of the upper clamping plate 14a, and the upper end of the upper hinge shaft 4 is fitted to the center of the lining 15. ing.
[0024]
When the output shaft 13 is rotated, the holding plates 14 a and 14 b and the lining 15 are integrally rotated, and the rotation torque of the output shaft 13 is transmitted to the upper hinge shaft 4.
[0025]
Further, when the panel 1 is rotated to the fully opened state or the fully closed state, or when the load on the upper hinge shaft 4 increases due to contact with an obstacle, the two holding plates 14 a and 14 b idle with respect to the lining 15. It has become.
[0026]
As shown in FIGS. 1 and 2, a lever drive shaft 18 is rotatably supported behind the upper frame 2, and one end of the lever drive shaft 18 is connected to an output shaft of a lock motor 19. Therefore, the lever drive shaft 18 is rotated by the operation of the lock motor 19.
[0027]
Behind each panel, a base end of a lock lever 20 provided corresponding to each panel 1 is fitted to the lever drive shaft 18, and the lock lever 20 is rotated integrally with the lever drive shaft 18. . Then, the lock lever 20 is rotated in a range from a lock position shown by a solid line in FIG. 2 to a lock release position shown by a chain line.
[0028]
When the lock lever 20 is rotated to the lock position, the tip of the lock lever 20 abuts on the upper rear surface of the panel 1 to prevent the panel 1 from rotating about the hinge shafts 4 and 5 as a fulcrum. Has become.
[0029]
As shown in FIG. 1, a limit switch 21 is provided on an upper frame 2 corresponding to the panel 1 located at one end side of the ten panels 1, and the panel 1 is rotated to a fully closed state. At this time, a detection signal is output.
[0030]
In the vicinity of the lock motor 19, the upper frame 2 is provided with limit switches 22a and 22b. The limit switch 22a detects a rotation angle of the lever drive shaft 18, and outputs a detection signal when the lock lever 20 is rotated to a lock position. The limit switch 22b detects a rotation angle of the lever drive shaft 18, and outputs a detection signal when the lock lever 20 is rotated to an unlock position.
[0031]
Next, the electrical configuration of the electric vertical panel louver will be described. As shown in FIG. 5, the detection signals of the limit switches 21, 22a, 22b are output to the control panel 23.
[0032]
The opening / closing motor 9 and the locking motor 19 operate based on a control signal output from the control panel 23.
The operation switch 24 includes a simultaneous switch and an individual switch. The simultaneous switch 24a shown in FIG. 6 is a switch for simultaneously operating panels of a plurality of units, and includes an open button 25, a stop button 26, a close button 27, a 30 ° button 28, and a 45 ° button 29.
[0033]
The individual switch is a switch for operating a panel for each unit, and has a configuration in which the 30 ° button 28 and the 45 ° button are omitted from the simultaneous switch 24a.
[0034]
Next, the operation of the electric vertical panel louver configured as described above will be described.
When the open button 25 is pressed, the lock motor 19 is operated and the lock lever 20 is rotated until the lock lever 20 reaches the unlock position, that is, until the limit switch 22b outputs a detection signal.
[0035]
Next, the opening / closing motor 9 operates to rotate each panel 1 in the opening direction. At this time, the opening / closing motor 9 is operated for 18 seconds by a single pressing operation of the open button 25, during which the panel 1 rotated to the maximum open position, that is, the direction orthogonal to the upper frame 2 is moved to the torque limiter 11 Idles and further rotation is prevented.
[0036]
By such an operation, all the panels 1 are rotated to the maximum open position before the operation of the opening / closing motor 9 stops.
When the close button 27 is pressed, the opening / closing motor 9 operates for 18 seconds to rotate each panel 1 in the closing direction. When the panel 1 at one end is rotated to the fully closed state during the operation for 18 seconds and the limit switch 21 outputs a detection signal, the opening / closing motor 9 stops and the lock motor 19 operates after 18 seconds. Then, the lock lever 20 is rotated from the lock release position to the lock position. When the limit switch 22a outputs the detection signal, the operation of the lock motor 19 is stopped.
[0037]
When the 30 ° button 28 or the 45 ° button is pressed, the opening / closing motor 9 operates for 18 seconds regardless of the rotation angle of the panel 1 at that time, and each panel 1 is initialized to the fully closed state.
[0038]
When the limit switch 21 outputs a detection signal during the operation for 18 seconds, after the opening / closing motor 9 operates in the panel closing direction for 18 seconds, the opening / closing motor 9 is turned on for a predetermined time corresponding to the designated angle. Operating in the opening direction, each panel 1 is rotated in the opening direction, and after a predetermined time, the operation of the opening / closing motor 9 is stopped.
[0039]
When the stop button 26 is pressed, the turning operation of the panel 1 is stopped at an arbitrary position.
With the electric vertical panel louver configured as described above, the following operational effects can be obtained.
(1) When the panel 1 is rotated, the rotation torque of the opening / closing motor 9 is transmitted to the upper hinge shaft 4 via the gear box 10 and the torque limiter 11. Therefore, when the panel 1 comes into contact with any obstacle, the torque limiter 11 idles, so that damage to the obstacle or the torque transmission mechanism can be prevented.
(2) After each panel 1 is rotated to the fully closed state, the rotation of each panel 1 can be prevented by the lock lever 20. Therefore, unnecessary rotation of the panel 1 when fully closed can be prevented while appropriately setting the frictional force of the torque limiter.
(3) When controlling the angle of the panel 1 to 30 ° or 45 °, each panel 1 is first initialized to a fully closed state using the idle rotation of the torque limiter 11, and then rotated to a predetermined angle. Therefore, the angle of each panel 1 can be controlled to 30 ° or 45 ° while being surely aligned.
(4) During the closing operation of the panel 1, the opening / closing motor 9 is operated for 18 seconds, and all the panels 1 are fully closed while the torque limiter 11 is idling, until the panel 1 at one end of one unit is fully closed. By detecting with the limit switch 21 whether or not the panel 1 has been rotated, it is possible to detect the rotation of all the panels 1 to the fully closed state with one limit switch. Therefore, the cost can be reduced by reducing the number of limit switches 21.
[0040]
The above embodiment can be modified as follows.
The angle of the panel 1 can be set to any angle other than 30 ° and 45 °.
The detection of the rotation angle of the panel 1 and the rotation angle of the lock lever 20 may be performed by using detection means other than the limit switch.
The operation time of the opening / closing motor 9 for bringing the panel 1 into the fully open state or the fully closed state is arbitrary as long as it is the time required to bring all the panels into the fully open state or the fully closed state. May be set to the time.
The upper hinge shaft 4 and the lower hinge shaft 5 may be provided at the center in the width direction of each panel.
[0041]
【The invention's effect】
As described in detail above, the present invention can provide an electric vertical panel louver that can prevent damage due to obstacles while ensuring that the rotation angles of the panels match each other. After each panel is rotated to the fully closed state, the rotation of each panel can be prevented by the lock lever. Therefore, unnecessary rotation of the panel when fully closed can be prevented while appropriately setting the frictional force of the torque limiter.
