Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric shutter installed at an opening in a building, etc., and more particularly to an automatic control method and an automatic control device for an electric YJJ shutter that allows the shutter to be opened and closed unattended. It is.

Generally, this type of electric shutter has a separate 49i'

Then, when a descending control command is issued to notify this, the shutter curtain collides with a stationary object and the stationary object 1+ is damaged.In addition, the shutter curtain reverses and the white body of the electric shutter is also damaged. There were some inconveniences with η17 such as

Therefore, a sensing sensor such as a tape switch is installed on the seat IJQ, and when the shutter curtain comes into contact with the sensing switch or an obstructive stationary object while the shutter curtain is lowering, the lowering of the shutter curtain is automatically stopped. There is a system in which the shutter curtain is repeatedly raised and lowered from a contact point of 1iW to a certain height until a book is removed. However, this is because the shutter curtain needs to be repeatedly lowered and lowered until the static object is removed.

Either this was the cause of the malfunction, or the automatic control mechanism for the electric shutter itself was complicated.

Furthermore, even if a person takes a dangerous action such as sneaking under the shutter curtain while the shutter curtain is lowering, if the person touches the detection sensor, the lowering will not stop. It is extremely dangerous and there is no excuse for a major lack of safety; for example, when taking this to the cash service room of a bank, it was possible to forcefully pass through the lowering shutter curtain without touching the sensor. There were also disadvantages such as people being trapped in the room, and it was necessary to further improve these points.

The present invention was devised in order to eliminate these drawbacks in view of the actual situation as described in L. When there is a stationary object that obstructs the lowering of the shutter curtain, the present invention is sensed and the shutter curtain is removed. Although it is an electric shutter that automatically stops the lowering of the shutter, when we search for people moving around the electric shutter, we find that the shutter curtain stops lowering, rises, and there is no moving object. To completely eliminate the inconvenience caused when a person forcibly crawls through a shutter that is being lowered by forcing the shutter to lower again when searching for the shutter, and to reduce failures without making the structure particularly complicated. The object of the present invention is to provide an automatic control method for an electric shutter and a control device for the same. In the first invention, the shutter curtain, which is automatically lowered by a control command, is stopped by at least one of detecting a stationary object that obstructs the lowering of the shutter curtain and searching for a moving object around the shutter curtain. After that, the stopped shutter curtain is controlled to search for a moving object and then lower again when the moving object is no longer present. The second invention is a control mechanism that issues a command to lower the shutter curtain.
Detects the presence of a stationary object that obstructs the shutter curtain's lowering and stops the descending] When the shutter curtain is stopped by any of the stop commands listed in -1-, the shutter curtain is searched for a moving object and then a re-down command is issued when the shutter curtain is detected to be absent. It is characterized by the fact that it has been provided.

Next, the present invention will be explained in more detail based on one embodiment shown in the drawings. In the drawing, l is an electric shutter that is attached to an opening, and a shutter curtain 2 that constitutes the electric shutter 1 is driven by a drive motor M in forward and reverse directions in response to a command from an automatic control mechanism A, which will be described later. By doing so, it is wound up or unwound onto the winding tram 3, thereby moving up and down to open and close the opening. 4 is a guide rail that guides the left and right sides of the shutter curtain 2; 5 is a shutter case; 6 is a sensing sensor attached to the seat plate 2a at the lowest end of the shutter curtain 2; When the shutter curtain 2
By contacting a stationary object that obstructs the lowering of the stationary object, the presence of the stationary object is sensed, and a switch contact SS, which will be described later, is closed. Further, in this embodiment, 7 is a search sensor attached to a bracket 5a extending from the shutter case 5, and the search sensor 7 detects moving objects such as people around the shutter curtain 2. This is a search sensor that searches for the presence of a switch contact R8, which will be described later, to close.

FIG. 3 shows a circuit diagram of an automatic control mechanism A for an electric shutter in which the present invention is implemented, where M is an lψ drive motor, MB is a brake device, and LsU is -1 = as long as min.
switch, LSD is the lower limit switch, MC
U is a changeover relay switch for ascending, MCD is a changeover relay switch for descending, RY1-3 is a relay switch, T is a timer switch, US is a - ascending switch, L) S is a descending switch, SS, RS are mentioned above. As shown above, the switch contacts of the nine sensing sensors 6, the search sensors 7, and the cl
, 2 are capacitors, and E is a power source. The above-mentioned lowering switch l) S is designed to be continuously closed for a predetermined period of time, for example, about 5 minutes, in response to an opening command from a control room (not shown). This is set in the embodiment.

Now, in order to lower the shutter curtain 2 which is fully open, the lowering control circuit that closes the lowering switch Y]S is sent out from the control room, and the lowering changeover relay switch MCD is switched to terminal 1
31, B:3, B4. B2. By keeping B3 in the i1 state, current flows from the power supply E to the 1ψ drive motor M, and the drive motor M moves to II! 1! IIL, the shutter curtain 2 is lowered to the lowest position where limit switches LS and D provided between terminals L2, 1, and 73 are opened. In addition, in order to raise the shutter curtain 2 in the fully open state 1P to -, a rise control command is issued from the control room to open the rise switch US, and 2, the rise changeover relay switch MCU is switched in turn] 2) The rise control circuit The side terminals B1, B3, B2, Ll, and L3 are maintained in a conductive state.

As a result, a current of the opposite phase to that described above flows from the power supply E to the drive motor M, driving it in reverse, and the shutter curtain 2 is brought to the highest position where the limit switch LSU provided between terminals T, 1, and B3 is opened. It is designed to cause it to rise.

Furthermore, during the lowering operation H9+ of the shutter curtain 2 described above, the sensing sensor 6 comes into contact with a stationary object such as luggage that obstructs the lower μt of the shutter curtain 2, and the sensor switch SS
When switching to the virtual line side, the relay switch RY3 is connected to the terminals r3+ and B due to the discharge from the capacitor C2 (in this embodiment, the period of discharge 111r is set to approximately 1 second).
The switch IJI is changed to open the switch contact RY:3 provided between RY and 2, thereby closing the drop control circuit and stopping the driving of the 1ψ motor M. . Furthermore, in this case, even if the discharge of the capacitor C2 ends and the relay switch 1/Y3 returns to its original state, and the switch contact RY3 closes and the terminals 131.83 become conductive, the shutter curtain 2 will still be lowered. Since it is located in the middle, the switch LSU located between the terminals 33 and 84 is open, and the configuration is such that the lowering control circuit will not become conductive due to this.

Further, when the search sensor 7 searches for a moving object such as a person, the switch contact R8 is closed and the relay switch RYI is switched to the state shown by the imaginary line between the two switch terminals RYI. Then, first relay switch RY
2 receives the discharge current of the capacitor C1 and during the discharge time (
In this embodiment, the switch contact RY2 provided between the terminals B1 and 82 is switched to open (about 1 second in this embodiment), and the terminals 131 and B2 are opened.
When the shutter curtain 2 is stopped and the shutter curtain 2 is brought into a non-conducting state, the timer switch 1 is activated and the timer switch 1 is set to 1 hour, which is shorter than the release market time of the contenza C1 described in 111f. After approximately 0.5 seconds in this embodiment), the switch contact 1'' provided between the terminals F33 and 84 opens, and the switch contact 1'' provided between the terminals 133 and B2 closes. And capacitor C2
When the discharging is completed, the relay switch RY2 is switched to close the switch contact RY2. Therefore, the lowering control circuit side where the switch terminal T is opened remains in a non-conductive state, but the lowering control circuit side where the switch terminal G is closed becomes conductive, and the shutter curtain 2 automatically rises. When the shutter curtain 2 rises to the fully open position, the rising limit l-

On the I control circuit side, the timer switch contacts T and Jji have been completed, but 1-4 limit switches 1 and SIJ are closed and maintained in this state (and- When the object at 1711 disappears and the switch contact 1S of search sensor l+7 opens, the timer switch returns to its original state τ
The terminals r133 and 134 become conductive, and this is true)
teIIfbi1%p +1! J) The motor 84 is driven to lower the shutter wheel 2 by 11 and lower the shutter wheel L7.

In the embodiment of the present invention constructed as described above, the control room is now located at the bottom 111. When the control command is issued, the shutter curtain 2 is lowered one step by opening the lowering switch DS in response to this command as described above.
3111-,. 7 fllll or 13I! Chain Seshimera 9,
Further, when the raising control command is issued, the calculation switch contact is closed and the shutter curtain 2 is raised and the opening 11 is opened.

In this way, in the present invention, the i of the shutter curtain 2 is
- Although the lowering and lowering movements can be performed automatically by control commands from the control room, the shutter curtain 2
If a person tries to sneak through the lowered shutter curtain 2 while the F lowering operation is in progress, the search sensor 7 searches for the person's 1st step, and the switch contact 1'<
Close S and switch relay switch RYI.

As a result, first the relay switch RY2 is switched to stop the lowering of the shutter curtain 2, and then,
By switching the timer switch T, the terminal B3 on the boost control circuit side
, B2 are electrically connected, and then the relay switch RY2 closes the switch contact RY2 when the capacitor CI has finished discharging, and the shutter curtain 2 rise control circuit r31
．． B3. I32, LL, ■, 3 become conductive, the shutter curtain 2 is forcibly raised to the fully open state, and the shutter curtain remains closed while the search sensor 7 searches for the presence of a moving object. 2 will be held at this fully open state for +h. Then, the item 4!1j no longer exists, and the switch contact R3 of the search sensor 4F7 opens.

, the l I no switches R and YI are switched, and in conjunction with this, the tammer switch '[' is switched, and the general switch contact T provided between the terminals 133 and 13/I on the lower one circuit side is switched.
As a result, the 11M control circuit side becomes conductive again and the shutter curtain 2 lowers again. If you want to obstruct the r-: ++; y: of the shutter curtain 2, there will be 819 digits on the seat plate 2a! 1) When the switch g1.1 is in contact with the surface-protruding object, the switch g1.
By adding one place to 't, 11 no switch 1 and Y3 are created! lfl+L, te, under shutter curtain 2, ?
, is automatically stopped and held in this state for one second. Therefore, there are no inconveniences such as damage to objects or damage caused by reverse winding of the electric lino shutter 1. In this case, in order to fully close the shutter/curtain 2, it is necessary for someone to come and remove the object.・ To 9 lfun /
Then, the search sensor 7 searches and detects this, and the sensor switch R8
will be closed. As a result, the above-mentioned relay switch RY1, relay switch RY2, and timer switch T are linked together to operate MO+, and the shutter curtain 2, which is in the middle of its descent, quickly opens to the full open state after reaching 1=-.+l. and stop. When a person moves away from the search range of the search sensor 7 by removing a surface-protruding object, the shutter curtain 2 is automatically lowered and is now fully opened.

If an object approaches the descending shutter curtain 2, it can be assumed that a dangerous act such as a person forcibly sneaking through the descending shutter curtain 2 may occur. In this case, according to the present invention, remarkable safety can be ensured by raising the shutter curtain 2 and stopping it in the fully open state.
- If an object is in the way, the lowering of the shutter curtain 2 is stopped by the sensing operation of the sensor 6 provided on the seat plate 2a - at least to prevent damage to the electric shutter 1, etc. can. Moreover, the sensing sensor 6
If 1ζ falls or stops when 1ζ is detected, it is necessary to remove the obstructive stationary object.
The search sensor 7 searches for the movement of objects during removal work, and as described above, after the shutter curtain 2 is fully opened, the shutter is automatically opened when there are no moving objects. Curtain 2 will begin to fall again. Therefore, there is no particular need for a separate command release mechanism for stopping when the sensing sensor (5) stops, and both the sensing sensor 6 that senses a stationary object and the search sensor 7 that searches for a moving object can be used. Despite the fact that it is provided with the following features, it is possible to significantly simplify the mechanism.

It should be noted that the present invention is of course not limited to the above-mentioned embodiments. The retrieval sensor may also be provided on both the front and rear sides of the shutter curtain, if necessary. Furthermore, in the present invention, the sensing operation of the sensing sensor is improved! Shutter curtain do 1 in IJ
It is designed to be held in a stopped state, but in this case, the shutter curtain is slightly moved:
It goes without saying that it may also be configured to do the following: n') Furthermore, in the embodiment No. 111j, the shutter curtain is configured to reach the fully open position and then stop when a moving object is detected by the search sensor,
It may be extremely safe in terms of safety, or it may not necessarily be raised to the fully open position, or in some cases it may not be raised at all, but only stopped at tIL. Lowering stop from either the sensor or the search sensor 1 - The shutter curtain is stopped by a command, and the shutter curtain is lowered again by the search sensor searching for a moving object and then searching for the moving object to disappear. 8) In short, the present invention is characterized by the above-mentioned configuration. If the lowering of the shutter curtain is detected by the sensor, the lowering of the shutter curtain will automatically stop1. By lowering or automatically stopping the shutter curtain by searching with the search sensor, the presence of moving objects and stationary objects can be detected separately by taking advantage of their properties, and the shutter curtain can be lowered or stopped automatically. A shutter curtain that can perform descending control with excellent safety, and also has a descending stop command of ρ:L++: After the search sensor detects the moving object, the moving object disappears. If you search for that, it will automatically start descending again. The shutter curtain automatically controls the presence or absence of obstructive static objects (f, n,) 16) and nearby moving objects. Nodome, a
can be completely satisfied.

This will of course prevent damage to the shutter curtain.

It is possible to make it extremely safe and 1/1. What's more, even if the shutter curtain stops when the sensing sensor detects the 11th position, it will be connected to the search sensor to search for the movement of people or objects when removing stationary objects. As a result, the mechanism for releasing the stoppage by the sensing sensor uses the search by the search sensor, and the shutter curtain is lowered again as in the past. Repeat ten times until the stationary object is removed.
f1. There is no need to separately provide a complicated release mechanism that causes a failure, such as lowering H9+, and the structure can be simplified.
