Description

  The present invention relates to a shutter device provided in an opening of a building, and more particularly to a shutter device in which a sheet shutter and a weight shutter are provided.

There are several types of shutter devices provided in the opening of a building, among which are heavy shutters and sheet shutters.
A heavy shutter has a shutter curtain formed by connecting a plurality of slender metal slats to form a shutter curtain. The heavy shutter is excellent in crime prevention and shielding when closed, and is often used as a management shutter or a fire shutter.
On the other hand, a shutter shutter is formed of a sheet-like material having flexibility, so that the opening / closing operation can be speeded up. Such a sheet shutter is applied to an opening portion that frequently needs to be shielded but frequently enters and exits. For example, in a manufacturing facility such as a factory, an opening portion where a forklift and a truck frequently come and go can be cited.

  Since the heavy shutter and the sheet shutter have their respective advantages as described above, there are many requests that both shutters be provided in the same opening, and the number of buildings that actually have both shutters is increasing.

  In such a shutter device, there are several patterns as to how the heavy shutter and the sheet shutter are arranged in the same opening. For example, the winding shafts of both shutters may be arranged separately on the interior and exterior sides of the upper part of the opening, or the winding shafts of both shutters may be arranged in parallel vertically. Furthermore, as described in Patent Document 1, there is a case in which a winding shaft of both shutters is included in one case. In many of these shutter devices, the weight shutter and the sheet shutter are each configured to be arbitrarily driven to open and close.

  Further, in Patent Document 2, in a shutter device provided with a heavy shutter (shutter) and a sheet shutter, for safety, the sheet shutter can be opened and closed only when the heavy shutter is at the upper limit (that is, fully opened). The invention is disclosed.

  By the way, since the descent speed of the shutter curtain during the closing operation of the heavy shutter is slow, it is relatively easy to pass through the shutter while the shutter curtain is descending. However, in the conventional shutter device in which the weight shutter and the sheet shutter are provided side by side, each of the shutters provided side by side is arbitrarily opened and closed as described above. There was a risk that the shutter would drop and collide. Further, the shutter device described in Patent Document 2 is not configured to solve the above problem when closing the heavy shutter.

  In view of the above problems, an object of the present invention is to provide a shutter device with improved safety in a shutter device provided with a heavy shutter and a sheet shutter.

The signal is received, and the sheet shutter control device is instructed to close the sheet shutter. , To solve the above problems by providing a shutter apparatus characterized by being capable formed by the control for starting the closure of the weight shutter after closing the completion of the sheet shutter.

  The invention according to claim 2 is a control method of the shutter device (1) provided with the heavy shutter (10) and the sheet shutter (30), and the operation of the heavy shutter is closed by the operating means (27, 46). A weight shutter control device for controlling the winding and unwinding of the shutter shutter of the heavy shutter provided in the heavy shutter, the winding of the shutter curtain of the sheet shutter provided in the sheet shutter, and The above-mentioned problem is solved by providing a method for controlling the shutter device that instructs the sheet shutter control device that controls rewinding to close the sheet shutter and starts closing the heavy shutter after the seat shutter is closed. To do.

  According to the present invention, when the heavy shutter is closed, the seat shutter is closed first, so that the opening is closed and the penetration can be prevented. Therefore, even if the closing speed of the heavy shutter is slow, the act of suddenly passing through is suppressed, and the safety can be improved. Furthermore, the operation of such a shutter device automatically improves safety because the operator only needs to close the heavy shutter device.

Thereafter, sensors for opening other than the phototubes 60 and 61 (for example, area sensors 63 and 64) are operated.

  The second is as follows. That is, when the seat shutter 30 is also closed after the weight shutter 10 is closed, the switch for opening the weight shutter is pressed among the operation panels 27 and 46. Then, only the heavy shutter 10 is fully opened by the heavy shutter control device 26. Thereafter, automatic opening / closing sensors (for example, area sensors 63 and 64) of the sheet shutter 30 are operated.

  The third is as follows. That is, when the seat shutter 30 is in the open posture after the heavy shutter 10 is closed, the switch for opening the heavy shutter of the operation panels 27 and 46 is pressed. Then, the weight shutter 10 is fully opened by the weight shutter control device 26. At the same time, automatic opening / closing sensors (for example, area sensors 63 and 64) of the sheet shutter 30 other than the phototubes 60 and 61 are operated.

  The fourth is as follows. That is, when the seat shutter 30 is in the open posture after the heavy shutter 10 is closed, the switch for opening the heavy shutter in the operation panels 27 and 46 is pressed. Then, the weight shutter controller 26 instructs the sheet shutter controller 45 to close only the sheet shutter 30. Next, the weight shutter 10 and the sheet shutter 30 are simultaneously opened.
