It is characterized by providing a roll screen winding automatic adjustment device that can automatically adjust the lowering and fixing position by the operation of a switch.

Description

Automatic winding device for roll screens {The control system of automatic winding for a roll-screen}

The present invention relates to a winding automatic adjustment device that can automatically adjust the lifting and lowering and fixing position of the roll screen (shade, roll buckle, insect screen).

In general, roll screens block windows during daylight and store them again when they are not needed, and have various decorative functions, and insect screens and blinds have the same functions. A variety of control devices are provided to enable the fixing of a certain position so that it can be stored in a wound state when it is not necessary to be cut off, and is representative of the Korean Utility Model Publication No. 95-9162, "Driver of Curtain Winding Machine". And a sprocket which is coupled to the chain on one side and protrudes on the other side, and an intermittent piece extends to the other side; Repeatedly formed friction difference, and the friction pad coupled to the outer projection of the cover body It is composed of a housing for receiving and extending the support piece and a latching jaw is formed on one side of the support piece, and a cam which is coupled to the shaft with a screw at the rear end of the housing to prevent the separation of the structures located therebetween without using a chain. A driving device is proposed to prevent the curtain member from being pulled directly or manipulated by an external factor such as a strong wind. This device is characterized in that the fixed state does not change even if the curtain is pulled directly without using the chain on the side, but there are many failures because the driving device and the adjusting device are configured separately. Therefore, there is no problem when the curtain is draped, but the chain is stretched even when the curtain is rolled up, which has a disadvantage of aesthetics. There are many problems, such as frequent repairs and even longer life.

In order to solve the above problems, the present invention installs a normal forward / reverse rotation motor on one side of a roller housing, and then directly connects a rotary roller to the motor shaft, while the rotating roller rotates forward and reverse by driving the motor. It is characterized by providing a roll screen winding automatic adjustment device which can automatically adjust the raising, lowering and fixing position of the screen wound on the roller by the operation of a switch.

* Explanation of symbols for main parts of the drawings

1 roller housing 2 motor case 3 motor shaft

3a: taper 5: working cam 5a: square stone bar

6: rotating roller 7a: square groove 8a: shaft

9: side plate member 9a: central shaft hole

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a perspective view showing the main part showing the coupling state of the motor shaft and the rotating roller in one side of the motor housing on one side of the roller housing;

2 is a main perspective view showing a coupling state between the central shaft hole of the other side plate member of the roller housing and the other side of the rotating roller;

The motor case 2 is installed to extend to the bottom of one side of the roller housing 1, but a normal forward and reverse rotation motor (not shown) is built in the motor case 2 so that the motor shaft 3 is installed in the case 2. 2) A rectangular roller bar 5a protruded to the inner side of the metal piece 4, but the actuating cam 5 is installed on the taper 3a surface of the motor shaft 3 so as to protrude toward one side of the actuating cam 5. (6) Inserted into the square groove (7a) of the one side cap (7), the shaft rod (8a) bulge on the other side cap (8) of the rotating roller (6) is in the central shaft hole (9a) of the side plate member (9) It is inserted and supported so that the rotating roller 6 is rotated forward and backward by the drive of the forward / reverse rotation motor inside the motor case (2).

10, the indentation surface is attached to one end of the screen,

11 screen

Denoted at 12 is an operation switch.

The present invention configured as described above has one end of the screen (11) attached to the concave inlet surface 10 on the rotary roller (6), the motor shaft (3) in the square groove (7a) of one side cap (7) of the rotary roller (6) in this state. Square stone bar (5a) of the actuating cam (5) inserted into the taper (3a) surface of the coupling is coupled and the shaft rod (8a) in the center of the other side cap (8) of the rotating roller (6) is the central shaft hole of the side plate member (9) The rotary roller 6 is arranged in the roller housing 1 while being coupled to the 9a,

In this state, when the operation switch 12 connected to the motor case 2 is used, the screen 11 on the rotary roller 6 is raised or lowered or fixed at a predetermined position. In other words, when the lower end of the operation switch 12 is pressed, the screen 11 is lowered while the rotary roller 6 rotates forward. When the upper part is pressed, the screen 11 is wound on the roller while the rotary roller 6 reverses. When the operation switch 12 is released during the operation as described above, the rotation of the rotating roller 6 is stopped and the screen 11 is fixed at any position of rising and falling.

The present invention as described above is to connect the rotary roller directly to the motor shaft of the motor case incorporating the normal forward and reverse rotation motor, and the other side of the rotary roller is built in the shaft hole of the side plate member, so that it is complicated as in the conventional chain or gear It shows stable operation without device.

As a simpler structure, the production and assembly is simple, and there is no failure as long as there is no damage to the motor, so durability is improved and productivity and economy are greatly improved due to the simple assembly structure.
