Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for controlling mlJ of an electric shutter that can be opened, closed, and stopped with a single operation switch.

[Prior Art and Problems to be Solved by the Invention] Generally, in this type of electric shutter, the electric motor that raises and lowers the shutter curtain can be driven forward and backward and stopped with a single operation switch. There is something. In this device, when the operation switch is operated, the shutter curtain is lowered when it is fully open, raised when it is fully open, and stopped when the shutter is in operation. It is designed to be left in a half-open state.

However, conventionally, with this device, if the operating switch is operated after the descending object is stopped in a half-open state,
For safety, the shutter curtain is always controlled to rise. Therefore, if you want to close the shutter from a half-open state, you must fully open the shutter curtain and then operate it again, or operate the one that is rising. It is necessary to stop it by operating a switch and then lower it by operating an operation switch, which makes the operation extremely troublesome and poses a problem in operability.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a control method for an electric shutter that can eliminate these drawbacks. When raising, lowering, and stopping a single operation switch, when moving a stationary object that is half-open, the control section that receives the signal from the operation switch must distinguish between the input signals. The present invention is characterized in that it is configured to output a corresponding ascending or descending control command to perform selective elevation control.

According to the present invention, with this configuration, selective elevation control can be performed from the half-open state, thereby improving operability.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a shutter curtain of an electric shutter, and the shutter curtain 1 is a push button switch 3 of a remote control transmitter 2, which will be described later, or a push button switch 4 on the shutter side (the operations of both switches are the same, so hereinafter referred to as the push button switch). The shutter case 6 is driven by the driving force of the opening/closing machine (electric motor) 5, which is driven forward and backward by the operation of the shutter case 6.
The opening can be opened and closed by moving up and down between a storage position in which it is wound around the inner winding drum 6a and a closed position in which it hangs down.

That is, when one push-button switch 3 provided on the remote control transmitter 2 is operated, a signal is emitted from the transmitting circuit 7 built into the remote control transmitter 2, and this signal is received by the receiving circuit 8 on the shutter side to perform a process described later. The control unit 9 judges the received signal as well as input signals from a sensor group, which will be described later, and controls the switch 5 via the switch drive circuit. It is designed to be driven or stopped.

Next, a method of controlling the control section 9 will be explained with reference to FIG. The control unit 9 includes a CPU, an I10 board, an interface, etc., and includes signals from the above-mentioned receiving circuit 8 and the push button switch 4 on the shutter side, as well as an upper limit switch 11, lower limit switches 1 to 12, and an obstacle detection sensor. A signal from 13 is input. When the control starts, it is first determined whether or not there is a signal input from the push button switch 3, and if there is a signal input, it is further determined whether the switch 5 is being driven. At this time, if the switch 5 is in operation, the switch 5 will be stopped, but when the switch 5 is stopped and the upper limit switch 11 is ON (the upper and lower limit switches 11 and 12 are fully open and fully closed) (shall be turned ON when the state is detected), the switch 5 is driven to the lowering side, and the lower limit switch 12 is turned ON.
In this state, the opening/closing machine 5 is driven to the upward direction. Furthermore, when the opening/closing machine 5 is in a stopped state and both the upper and lower limit switches 11 and 12 are OFF, that is, when the shutter is in a half-open state, the input signal is longer than a preset time T (1 second in the example). It is determined whether or not the input signal continues, and if the input signal is shorter than the set time T, the switch 5 is driven to the upward side, and the input signal is shorter than the set time T.
If it exceeds the above, the opening/closing machine 5 is driven to the lowering side. In addition, the switch 5 once driven by the operation of the pushbutton switch 3 is operated by the upper limit switch 11.
, the lower limit switch 12, and the obstacle detection sensor 13 are controlled to be continuously driven until one of them is detected or the push button switch 3 is operated again. Note that 15 is a control panel in which the control mechanism is installed.

In the embodiment of the present invention configured as described above, when the push button switch 3 is operated, the shutter will be closed when it is fully open, and it will be opened when it is fully opened, and when the shutter is in operation, it will be closed. However, when the shutter curtain 1 is stopped halfway and is in a half-open state, if the push button switch 3 is pressed for a shorter time than the set time T, it will move upward, and if the push button switch 3 is pressed for a longer time than the set time T. In this case, it will operate downward.

As described above, in the present invention, although the shutter curtain 1 can be raised, lowered, and stopped with a single push button switch, the shutter curtain 1 can be operated from a half-open state where it has stopped halfway. push button switch 3
The rising and rising operations can be arbitrarily selected by pressing for a shorter time or longer than a preset time T. Therefore, there is no need to wait for the shutter curtain 1 to stop at the fully open position and then operate the push button switch 3 again when closing the shutter from a half-open state, as in the conventional case. The shutter can be closed by a simple selection operation by adjusting the pressing time of the push button switch 3, thereby significantly improving the operability of the shutter.

Furthermore, in the setting of raising/lowering selection in the half-open state of this product, when the push button switch 3 is pressed for a shorter time than the set time T, it is set as the rising side, and if you want to lower it, you have to press the push button switch 3 for a relatively long time. Therefore, even if the shutter curtain 1 is operated in a hurry in an emergency, the shutter curtain 1 will operate on the safe side, that is, on the rising side, and therefore, the shutter curtain 1 can be operated in a half-open state to select the elevation. It also has excellent safety without compromising safety.

It should be noted that the present invention is of course not limited to the above-mentioned embodiments. For example, it is necessary to determine whether the operation of the push button switch 3 performed with the shutter half open is an up command or a down command within a set time. The determination may be made based on the number of operations, such that if the push button switch 3 is pressed once, it will go up, and if it is pressed twice, it will go down.

Further, the above-mentioned control can be implemented by a control circuit using relay contacts, for example, as shown in FIG. This device is configured so that a switch operation of 0.1 seconds or less is determined to be an erroneous operation by the timer switch T□, and in the circuit diagram, the LSU and LSD are always OFF.
This is an upper/lower limit switch that turns off when the detection is activated with N, and the symbol gate turns on when the relay switch is energized.
The A contact, symbol , becomes O when the relay switch is energized.
This is a b contact that becomes an FF.

[Operations and Effects] In short, the present invention is configured as described above, and although the shutter curtain can be raised, lowered, and stopped with a single operation switch, it is possible to operate the shutter curtain in a half-open state. If the operating switch is operated while the vehicle is stopped, the control section that receives this signal will determine the difference in the input signals and output a control command for raising or lowering. Therefore, in the half-open state, it is possible to arbitrarily select and operate raising and lowering. Therefore, when closing from a half-open state as in the conventional case, the shutter curtain is raised once,
It can be closed with a simple selection operation without having to perform troublesome and complicated operations such as having to operate the operation switch again after a certain time, thereby providing an excellent product with greatly improved operability. can.
