When the control unit 71 receives the predetermined detection signal, the control unit 71 controls the drive motor 30, and the closing body 21 performs a predetermined obstacle detection operation or stops at the upper limit position. The first sensor 61, the second sensor 62,
The detection unit 76 is constituted by the load sensing means 75 and the like.

Next, the operation of the first embodiment will be described with reference to FIG.
This will be described with reference to FIG.

When the closed part 12 is fully opened, the operating means
When the closing operation section 65 is operated, the closing body 21 starts a lowering operation as a closing operation based on the driving force from the driving motor 30 (step 1), and the closing body 21 is moved from a predetermined fully open stop position. It descends in the closing direction C along the closing part 12.

When the opening operation section 66 is operated when the closing body 21 is lowered (step 2), the closing body 21 performs an ascending operation as an opening operation (step 3). When the stop operation unit 68 is operated when the closing body 21 is lowered (step 4),
The closing body 21 stops (step 5). Meanwhile, closed body
When the load sensing unit 75 detects an obstacle (not shown) by sensing the load on the closing body 21 during the descent of the closing body 21 (step 6), the control unit 71 uses the recognizing means 72 to recognize the operation abnormality of the closing body 21. The closing motor 21 is recognized and the drive motor 30 is controlled by the closing body control means 74, whereby the closing body 21 performs a predetermined obstacle detecting operation (Step 7).
When the locking engagement portion 26 at the lower end of the first sensor 61 passes the position facing the first sensor 61, the first sensor 61 detects the closing body 21 and transmits a predetermined detection signal to the control unit 71.

When receiving the predetermined detection signal from the first sensor 61 (step 8), the control section 71 starts the timer means 73 (step 9), and starts from when the first sensor 61 detects the closing body 21. The elapsed time of is counted.

Then, the control section 71 determines whether or not the elapsed time measured by the timer means 73 is equal to a predetermined time (step 10).

When the control unit 71 determines that the elapsed time has reached a predetermined time and the time has elapsed, the recognition unit 72 recognizes an abnormal operation of the closing body 21, and the closing body control unit 74 controls the drive motor 30. Thus, the closing body 21 performs a predetermined obstacle detecting operation (step 11).

For example, the lower end of the closing body 21 is a guide rail.
In a state near the lower end of 13, as shown in FIG. 1, an obstacle A having a relatively small size is sandwiched between the center of the lower end of the closing body 21 in the left-right direction and the lower frame 15. In some cases, the control unit 71 determines that the time is up, and
, And controls the closing body 21 to perform a predetermined obstacle detection operation.

On the other hand, without operating the open operation unit 66 and the stop operation unit 68 (steps 12 and 13), the timer means
Before the elapsed time measured in 73 reaches a predetermined time set in advance, the locking engagement portion 26 at the lower end of the closing body 21 reaches the position facing the second sensor 62, and the second sensor 62 When the control unit 71 detects the closing body 21 and transmits a predetermined detection signal to the control unit 71, the control unit 71 receives the detection signal from the second sensor 62 (step 14), and the closing body control unit 74 To control the drive motor 30, the closing body 21 stops at the lower limit position (step 15), and the closed portion 12 is fully closed. Open operation section
When the button 66 is operated (step 12), the closing body 21 performs a lifting operation as an opening operation (step 16). When the stop operation section 68 is operated (step 13), the closing member 21 is closed.
Stops (step 17).

After the locking engagement portion 26 of the closing body 21 has passed the position facing the stopper body 45 of the locking device 35, the stopper body 45 has a distal end portion at the operation facing surface portion 54 of the guide blocking plate portion 51. To a state in which the closing body 21 is locked by the lock device 35. In the locked state of the closing body 21, when the closing body 21 in the fully closed state is pushed up in the opening direction O, and the stopper body 45 in the advanced state is pressed by the locking engagement portion 26,
The tip of the stopper body 45 is the opposing surface of the guide blocking plate 51
It is locked by being pressed against 54, and the stopper body is
Rotation of 45 is prevented. In a state where the stopper body 45 and the operation facing surface portion 54 are pressed against each other, the stopper body 45 is supported as a doubly supported structure by the apparatus main body portion 41 and the guide blocking plate portion 51, and a predetermined strength is secured. Therefore, the movement restriction state of the locking engagement portion 26 by the stopper body 45 is not released.

The operation of detecting a predetermined obstacle of the closing body 21 (steps 7 and 11) will be described with reference to FIG. 4. After the closing body 21 stops for a predetermined time (step 18). Then, the ascending operation which is the opening operation is started (step 19), and the ascending operation is performed in the opening direction O along the closed portion 12.

When the closing operation section 67 is operated at the time of raising the closing body 21 (step 20), the closing body 21 performs a lowering operation as a closing operation (step 21). When the stop operation unit 68 is operated when the closing body 21 is raised (step 2).
2), the closing body 21 stops (step 23).

When the lifting operation of the closing body 21 proceeds and the contact plate 25 of the baseboard 23 at the lower end of the closing body 21 comes into contact with the lower surface of the shutter box 18 or the like, the load sensing means 75 closes during the upward movement. Body 21
It is detected that the closing body 21 has reached the upper limit position by sensing the load on the vehicle (step 24). Based on the detection signal of the load sensing means 75, the control unit 71 controls the drive motor 30 with the closing body control means 74, the closing body 21 stops at the upper limit position (step 25), and the closed part 12 is fully opened. State.

On the other hand, when the opening operation part 66 of the operating means 65 is operated in the fully closed state of the part to be closed 12, the lock device 35 enters the unlocked state based on the control output from the control unit 71.
That is, the stopper body 45 of the lock device 35 rotates in the predetermined direction to change from the advanced state to the retracted state, and the entire stopper body 45 retreats from the moving position of the locking engagement portion 26 and enters the device main body 41. Next, a driving force is output from the drive motor 30 based on the control output from the control unit 71, the closing body 21 starts the opening operation, and the closing body 21 moves along the closed part 12 from a predetermined fully closed stop position. And rises in the opening direction O. During this ascent, the locking engagement portion 26 of the baseboard 23 of the closing body 21
The movement is not restricted by the stopper body 45 of the stopper member 35, and continues to rise unless the closing operation part 67 or the stop operation part 68 is operated. Then, when the closing body 21 reaches the upper limit position, the output of the driving force of the motor 65 is prohibited, and the closing body 21 stops at the upper limit position which is a predetermined fully open stop position.

As described above, according to the above-described embodiment, the control unit 71 operates the closing body 21 normally or abnormally based on the detection of the detecting unit 76 having the first sensor 61 and the second sensor 62. Can properly recognize the operating state of the
The obstacle A that has entered the inside 12 can be reliably detected, and it is possible to quickly and appropriately respond to an abnormal operation of the closing body 21 when there is an obstacle.

For example, since the obstacle detection is performed by using the plurality of first sensors 61 and the second sensors 62 which are arranged side by side in the moving direction of the closing body 21, it is impossible to detect only the load sensing means 75. Closed body that can handle small obstacles A
21 operation abnormalities can be properly dealt with.

That is, in the load sensing means 75, the closing body 21
It is necessary to strictly set the balance between the spring torque of the winding and the torque applied to the winding by the slat 22 based on the fact that the spring expands and contracts in the moving direction, taking into account the respective variations and the like. It is difficult to make settings to support obstacle detection. For this reason, there is a possibility that the obstacle A having a relatively small size as shown in FIG. 1 cannot be detected with the configuration including only the load sensing means 75, but in the present embodiment, even the small obstacle A can be reliably detected.

Since the stopper 45 is disposed between the first sensor 61 and the second sensor 62, the control unit 71 closes based on the detection signal from each of the first sensor 61 and the second sensor 62. It can be recognized that the body 21 is securely locked by the lock device 35.

Further, the stopper body 45 regulates the movement of the closing body 21 in the opening direction O, and the groove portion 60 controls the movement of the closing body 21 in the opening direction O.
Since the closing body 21 in the locked state cannot move in any of the vertical direction and the front-back direction of the shutter device 11, the baseboard 23 and the lower frame 15 of the closing body 21 are restricted. No gap is formed between them. Therefore, the locked state of the closing body 21 by the lock device 35 is effectively prevented without the prying open of the locked closing body 21 using the gap between the baseboard 23 and the lower frame 15 of the closing body 21. It can be held, and the fully closed state of the closed portion 12 can be appropriately maintained.

Further, the locking engagement portion 26 of the baseboard 23 of the closing body 21
Of the locking device 35 and the guide blocking plate 51
Since it is located in the gap 57 between the groove portions 60 between the locking engagement portions 26
Operating range can be reduced. Therefore, for example, rattling of the closing body 21 in the fully closed state can be prevented. Further, the protrusion length of the stopper body 45 in the advanced state from the apparatus main body 41 is sufficient in the front-rear direction dimension of the shutter device 11 in the gap 57 between the apparatus main body 41 and the guide blocking plate 51. The size of the stopper 45 can be reduced, and the driving force for rotating the stopper body 45 can be reduced.

Next, the structure of a second embodiment of the closing device of the present invention will be described with reference to FIG. It should be noted that the same parts as those in the first embodiment will be described with the same reference numerals.

The detecting unit 7 of the shutter device 11a shown in FIG.
6a is a plurality of closed body detecting means instead of the first sensor 61 and the second sensor 62 of the shutter device 11 shown in FIG.
For example, it has two first sensors 81 and two second sensors 82.

The first sensor 81 and the second sensor 82
Is the direction intersecting with the moving direction of the closing body 21, that is, the closing body 21
Are arranged side by side at predetermined intervals along a direction (horizontal direction of the shutter device 11) orthogonal to the moving direction of the shutter device 11. The direction perpendicular to the moving direction of the closing body 21 means not the thickness direction of the closing body 21 (the front-back direction of the shutter device 11) but the width direction of the closing body 21 (the left-right direction of the shutter device 11). .

That is, the first sensor 81 and the second sensor
Each of 82 is a predetermined movement start position that is a movement start position in the movement direction of the closing body 21, for example, a distance from a predetermined fully open stop position or the like is the same position, that is, they are respectively arranged at the same height position, The closing bodies 21 are juxtaposed with an interval according to a width dimension which is a length dimension in the left-right direction.

For example, the first sensor 81 is provided on the front side near the lower end of the device main body 41 of the lock device 35 on the left side when viewed from the front, which is one side, and the second sensor 81 is mounted on the front side which is the other side. It is provided on the front side near the lower end of the device body 41 of the lock device 35 on the right side as viewed. Each of the first sensor 81 and the second sensor 82 is located at a position near the lower end of the guide rail 13 in a state where the first sensor 81 and the second sensor 82 are opposed to each other with the closed portion 13 therebetween.
The detection function of the lower limit which is the 21 closure limit, that is, the closed body
It also has a function of detecting that the baseboard 23, which is the lower end of 21, has reached the lower limit that is the closing limit.

The timer means 73 of the control unit 71a of the shutter device 11a shown in FIG. 5 is different from the timer means 73 of the shutter device 11 shown in FIG. An elapsed time from when only one of the second sensor 82 and the second sensor 82 detects the closing body 21 is measured.

Further, the closing body control means 74 of the control section 71a of the shutter device 11a shown in FIG.
Unlike the first closing body control means 74, the other first sensor 81
Alternatively, when the elapsed time measured by the timer means 73 reaches a predetermined time set in advance without the second sensor 82 detecting the closing body 21, the closing body 21 performs a predetermined obstacle detecting operation. The drive motor 30 is controlled as described above. The shutter device 11a shown in FIG. 5 has substantially the same structure as the shutter device 11 shown in FIG. 1 in other respects.

Next, the operation of the second embodiment will be described with reference to FIGS.

When the closed portion 12 is fully opened, the operating means
When the closing operation section 65 is operated, the closing body 21 starts a lowering operation as a closing operation based on the driving force from the driving motor 30 (step 1), and the closing body 21 is moved from a predetermined fully open stop position. It descends in the closing direction C along the closing part 12.

When the opening operation section 66 is operated when the closing body 21 is lowered (step 2), the closing body 21 performs an ascending operation as an opening operation (step 3). When the stop operation unit 68 is operated when the closing body 21 is lowered (step 4),
The closing body 21 stops (step 5). Meanwhile, closed body
When the load sensing unit 75 detects an obstacle (not shown) by sensing the load on the closing body 21 during the descent of the closing body 21 (step 6), the control unit 71 uses the recognizing means 72 to recognize the operation abnormality of the closing body 21. The closing motor 21 is recognized and the drive motor 30 is controlled by the closing body control means 74, whereby the closing body 21 performs a predetermined obstacle detecting operation (Step 7).
The pair of left and right locking engagement portions 26, 26 at the lower end of the armature have passed the position facing the stopper body 45, and then have reached the position facing the left and right pair of the first sensor 81 and the second sensor 82. And Then, both the first sensor 81 and the second sensor 82
Detects the closing body 21 and transmits a predetermined detection signal to the control unit 71a, and the control unit 71a controls the drive motor 30 by the closing body control means 74 by simultaneous reception of the predetermined detection signal. Then, the closing body 21 stops at the lower limit position, and the closed portion 12 is in the fully closed state.

On the other hand, for example, as shown in FIG. 5, an obstacle A having a relatively small size is sandwiched between one end of the lower end of the closing body 21 in the left-right direction and the lower frame 15, and the closing body 21 is closed. For example, when the lower end is inclined, one of the first sensor 81 and the second sensor 82, that is, the first sensor 81 or the second sensor 82, for example, the first sensor 81 detects the closing body 21 and performs a predetermined detection. It is assumed that the signal has been transmitted to the control unit 71a (step 8). Then, upon receiving the predetermined detection signal, the control section 71a starts the timer means 73 (step 9), and counts the elapsed time from when the first sensor 81 detects the closing body 21.

Then, the controller 71a determines whether or not the elapsed time measured by the timer means 73 is equal to a predetermined time (step 10).

When the control unit 71a determines that the elapsed time has reached the predetermined time and the time has elapsed, the recognizing means 72 recognizes the operation abnormality of the closing body 21, and the closing body controlling means 74 controls the drive motor 30. Thus, the closing body 21 performs a predetermined obstacle detecting operation (step 11).

On the other hand, without operating the open operation unit 66 and the stop operation unit 68 (steps 12 and 13), the timer means
Before the elapsed time measured at 73 reaches a predetermined time set in advance, the obstacle A is removed, and the other of the first sensor 81 and the second sensor 82, for example, the second sensor 82 is closed. Is detected and a predetermined detection signal is transmitted to the control unit 71a, the control unit 71a receives the detection signal from the second sensor 82 (step 14), and the closing body control unit 74
To control the drive motor 30, the closing body 21 stops at the lower limit position (step 15), and the closed portion 12 is fully closed. When the opening operation unit 66 is operated (step 12), the closing body 21 is operated.
Performs a lifting operation as an opening operation (step 16). When the stop operation unit 68 is operated (step 13),
The closing body 21 stops (step 17).

After the locking engaging portion 26 of the closing body 21 has passed the position facing the stopper body 45 of the locking device 35, the stopper body 45 has a distal end portion at the working facing surface portion 54 of the guide blocking plate portion 51. To a state in which the closing body 21 is locked by the lock device 35. In the locked state of the closing body 21, when the closing body 21 in the fully closed state is pushed up in the opening direction O, and the stopper body 45 in the advanced state is pressed by the locking engagement portion 26,
The tip of the stopper body 45 is the opposing surface of the guide blocking plate 51
It is locked by being pressed against 54, and the stopper body is
Rotation of 45 is prevented. In a state where the stopper body 45 and the operation facing surface portion 54 are pressed against each other, the stopper body 45 is supported as a doubly supported structure by the apparatus main body portion 41 and the guide blocking plate portion 51, and a predetermined strength is secured. Therefore, the movement restriction state of the locking engagement portion 26 by the stopper body 45 is not released.

The operation of detecting a predetermined obstacle of the closing body 21 (steps 7 and 11) will be described with reference to FIG. 7. After the closing body 21 stops for a predetermined time (step 18). Then, the ascending operation which is the opening operation is started (step 19), and the ascending operation is performed in the opening direction O along the closed portion 12.

When the closing operation section 67 is operated at the time of raising the closing body 21 (step 20), the closing body 21 performs a lowering operation as a closing operation (step 21). When the stop operation unit 68 is operated when the closing body 21 is raised (step 2).
2), the closing body 21 stops (step 23).

When the lifting operation of the closing body 21 proceeds and the contact plate 25 of the baseboard 23 at the lower end of the closing body 21 comes into contact with the lower surface of the shutter box 18 or the like, the load sensing means 75 is closed during the upward movement. Body 21
It is detected that the closing body 21 has reached the upper limit position by sensing the load on the vehicle (step 24). Based on the detection signal of the load sensing means 75, the control unit 71 controls the drive motor 30 with the closing body control means 74, the closing body 21 stops at the upper limit position (step 25), and the closed part 12 is fully opened. State.

On the other hand, when the opening operation part 66 of the operating means 65 is operated in the fully closed state of the part to be closed 12, the lock device 35 enters the unlocked state based on the control output from the control unit 71.
That is, the stopper body 45 of the lock device 35 rotates in the predetermined direction to change from the advanced state to the retracted state, and the entire stopper body 45 retreats from the moving position of the locking engagement portion 26 and enters the device main body 41. Next, a driving force is output from the drive motor 30 based on the control output from the control unit 71, the closing body 21 starts the opening operation, and the closing body 21 moves along the closed part 12 from a predetermined fully closed stop position. And rises in the opening direction O. During this ascent, the locking engagement portion 26 of the baseboard 23 of the closing body 21
The movement is not restricted by the stopper body 45 of the stopper member 35, and continues to rise unless the closing operation part 67 or the stop operation part 68 is operated. Then, when the closing body 21 reaches the upper limit position, the output of the driving force of the motor 65 is prohibited, and the closing body 21 stops at the upper limit position which is a predetermined fully open stop position.

The shutter device 11a according to the second embodiment also includes the shutter device 1 according to the first embodiment.
As in 1, the first sensor 81 and the second sensor
Since the operation abnormality of the closing body 21 can be recognized based on the detection of the detection unit 76a having 82, for example, the obstacle A that has entered the closed part 12 can be reliably detected, and the abnormal operation of the closing body 21 can be quickly and appropriately detected. And the like.

Further, in the shutter device 11a, the first sensor 81 and the second sensor 82 are juxtaposed at a predetermined interval along the left and right horizontal direction, which is the direction intersecting the moving direction of the closing body 21, so that the obstacle is not obstructed. The lower end tilts due to the presence of A. Lower frame 15
It is possible to prevent the closing body 21 from stopping in a state where a gap is formed between them. Further, the control unit 71a can recognize that the closing body 21 is securely locked by the left and right locking devices 35 based on the detection signals from each of the first sensor 81 and the second sensor 82.

Note that, in the first embodiment,
The detecting unit 76 includes two first sensors having different height positions from each other.
Although described as a configuration having the 61 and the second sensor 62,
A configuration having three or more closed body detecting means having different height positions may be employed. For example, as shown in FIG. 8, in addition to the first sensor 61 and the second sensor 62, the existing position where the stopper body 45 is present Stopper interlocking sensor as a closing body detecting means located at the same position as the stopper body, that is, at the same height position as the stopper body 45
A configuration having 63 may be used. This stopper interlocking sensor 63
Is for detecting the closing body 21 via the stopper body 45,
For example, it is embedded in the device main body 41 of the lock device 35. The control unit 71 controls the drive motor 30 so that the closing body 21 stops at the predetermined lower limit position, for example, when receiving detection signals from all of the first sensor 61, the stopper interlocking sensor 63, and the second sensor 62. Control.

Further, in the shutter device 11 and the like of the first embodiment, the control unit 71 has been described as having the timer means 73 and the closing body control means 74. For example, the shutter as a closing device shown in FIG. As in the device 11b, the control unit 7
1 may have a configuration including a distance measuring means 73a and a closing body control means 74a instead of the timer means 73 and the closing body control means 74.

The distance measuring means 73a measures the moving distance of the closing body 21 from when the first sensor 61 as one closing body detecting means detects the closing body 21, for example. In other words, the distance measuring means 73a is composed of, for example, a rotary encoder or a Hall IC, a counter, or the like, and the closed body is determined based on the rotation speed and the rotation angle of the winding body 20 and the output shaft of the drive motor 30 as the closed body driving means.

Further, the closing body control means 74 of the control section 71 determines whether the second sensor 62a does not detect the closing body 21 and the elapsed time from the time when the first sensor 61a is measured by the timer means 73 is detected. When the preset time is reached, the closing body
The drive motor 30 is controlled so that 21 performs a predetermined obstacle detection operation, which is a predetermined abnormality detection operation. Further, the closing body control means 74 is configured to detect the time elapsed from the time when the second sensor 62a is measured by the timer means 73 without the third sensor 63 detecting the closing body 21 and to set a predetermined time which is set in advance.

It is possible to properly recognize operation states such as normal operation and abnormal operation of the object 21. For example, it is possible to reliably detect an obstacle A that has entered the closed part 12, and to perform an operation abnormality of the closed body 21 when there is an obstacle. Operational effects such as quick and appropriate response can be achieved.

On the other hand, for example, a shutter device 11e as a closing device in FIG. 12 may be used.
