されたものである。Wrinkles often occur in the film in greenhouse winding curtain devices. In the conventional greenhouse winding curtain device, however, when the wrinkled film is wound on the movable winding shaft, the portion of the film roll 71 'corresponding to the wrinkles is necessarily thicker than the portion without wrinkles. Therefore, the thick side of the film roll 71 'advances faster than the thin side of the film roll 71'. That is, in the film roll 71 ′ wound around the same movable winding shaft, the side having a thickened portion due to wrinkles moves faster than the other small diameter side. Therefore, when a film having wrinkles is wound around the movable winding shaft, the movable winding shaft meanders or moves unevenly in the left and right directions. As a result, a large amount of force is required to wind the film, and the film is forced with excessive force,
The film may be damaged and the curtain device itself may be damaged. Further, if the movable winding shaft on which the film is wound is located in a non-uniform position on the left and right, unfavorable shadows may be cast on the plants in the greenhouse. Furthermore,
The film in the greenhouse has the problem that water accumulates on the flurum. That is, water droplets drop on the film in the greenhouse due to dew condensation of the greenhouse body or water droplets are generated on the film due to dew condensation of the film itself or other things in the greenhouse,
Such water droplets eventually form a water pool on the film. Such pools can damage the curtain system and even break the film. The present invention has been made to solve the above problems.

及びフィルム巻取軸の２倍の速さで移動する。According to the present invention, in the greenhouse curtain device of claim 1, when the film (curtain) is in an open state, the film winding shaft and the wire / film connecting shaft are films. The wire winding shaft is located in the vicinity of the end fixing pipe, and the wire winding shaft is located at a substantially intermediate position between the wire fixing pipe and the film fixing pipe. In these positions, the film winding shaft is in a state of maximally winding the film, and the wire winding shaft is in a state of maximally winding the wire. When the film is closed from this state, the wire winding shaft is rotated in the wire winding direction by the drive motor. The wire winding shaft moves in the direction of the wire end fixing pipe by winding the wire. When the wire winding shaft rotates, the film winding shaft also rotates at the same time, and while the film is being fed, the film winding shaft moves in the direction of the wire end fixed pipe at the same speed as the wire winding shaft. At this time, since the wire winding shaft moves in the direction of the wire end fixing pipe by winding the wire, the wire / film connecting shaft is pulled in the direction of the wire end fixing pipe by the plurality of wires. Therefore, the film is pulled toward the wire end fixing pipe on both sides of the film winding shaft. That is, the wire winding shaft is kept parallel to the wire end fixing pipe, the wire / film connecting shaft is kept parallel to the wire winding shaft, and the film winding shaft is kept parallel to the wire / film connecting shaft. Since the film take-up shaft is connected to the wire take-up shaft or the drive motor via the spring, a constant tension is applied to the film take-up shaft by the spring, and the film take-up shaft is rotated by the film. As a result of the change in roll thickness being absorbed by the spring, the film winding shaft and the wire winding shaft can move at the same speed. Further, since the film unwound from the film winding shaft is pulled between the film winding shaft and the wire / film connecting shaft and between the film winding shaft and the film end fixing pipe, the film is less likely to be wrinkled. The film is completely closed when the wire winding shaft winds the wire and moves to a position close to the wire end fixing pipe. At this time, the wire / film connecting shaft is in a position close to the wire winding shaft, and the film winding shaft is in a substantially intermediate position between the wire end fixing pipe and the film end fixing pipe. That is, the film is spread over almost the entire space between the wire end fixed pipe and the film end fixed pipe. In other words, the film winding shaft is in a state where the film is maximally unwound, and the wire winding shaft is in a state where the wire is maximally wound. Incidentally, the wire / film connecting shaft moves at twice the speed of the wire winding shaft and the film winding shaft.

する。When the film is opened from this state, the wire winding shaft is rotated by the drive motor in the wire feeding direction. At that time, the film take-up shaft connected to the wire take-up shaft or the drive motor via the spring rotates in the film take-up direction, and the film take-up shaft takes up the film to fix the film end fixing pipe. Move in the direction. At this time, since the film winding shaft moves in the direction of the film end fixing pipe by winding the film, the wire / film connecting shaft is pulled in the direction of the film end fixing pipe by the film. Therefore, the film is pulled on both sides of the film winding shaft. That is, the film winding shaft is kept parallel to the film end fixing pipe, the wire / film connecting shaft is kept parallel to the film winding shaft, and the wire winding shaft is kept parallel to the wire / film connecting shaft. Since the film take-up shaft is connected to the wire take-up shaft or the drive motor via the spring, a constant tension is applied to the film take-up shaft by the spring, and the film take-up shaft is rotated by the film take-up shaft. As a result of the change in roll thickness being absorbed by the spring, the film winding shaft and the wire winding shaft can move at the same speed. Further, the film wound by the film winding shaft is pulled between the film winding shaft and the wire / film connecting shaft which are parallel to each other and between the film winding shaft and the film end fixing pipe which are parallel to each other. Therefore, not only wrinkles are not easily generated in the film, but even if wrinkles are generated in the film, the wrinkled part is strongly wound around the film winding shaft, and the wrinkle-free part is weakly wound around the film winding shaft. The film roll wound around the film winding shaft maintains a constant thickness, so that the film winding shaft is prevented from meandering and uneven lateral movement. When the film winding shaft winds up the film and moves to a position close to the film end fixing pipe, the film is completely opened. That is, the film is almost completely removed from between the wire end fixed pipe and the film end fixed pipe. At this time, the wire / film connecting shaft is in a position close to the film winding shaft, and the wire winding shaft is in a substantially intermediate position between the wire end fixing pipe and the film end fixing pipe.
In other words, the film winding shaft is in a state in which the film is maximally wound, and the wire winding shaft is in a state in which the wire is maximally unwound. Incidentally, the wire / film connecting shaft moves at twice the speed of the wire winding shaft and the film winding shaft. Even in the case of horizontal tensioning in which there is no difference in height between the wire end fixed pipe and the film end fixed pipe, the above operation is not hindered at all. Figure 9 (1) when the film is closed
Water 22 often accumulates on the film as shown in
When the film take-up shaft winds up the film and moves to a position close to the film end fixed pipe, the wire
The film connecting shaft is also close to the film winding shaft. That is, since the wire / film connecting shaft, the film winding shaft, and the film end fixing pipe are substantially vertically aligned as shown in FIG. 9B, the water 22 on the film falls from the film.

前述の通りである。As described above, in the winding curtain device for a greenhouse of the present invention, not only wrinkles do not easily occur in the film, but also the film winding shaft does not meander or move unevenly from side to side. . Since no excessive force is applied to the film, damage to the film is prevented, the life of the film is extended, and the types of films that can be used are increased. Further, even in the case of horizontal tensioning in which there is no difference in height between the wire end fixed pipe and the film end fixed pipe, there is no problem in the operation. Further, since the film take-up shaft takes up the films before and after the film in a doubled state, the number of rotations of the film take-up shaft can be reduced. in addition,
As described above, the water on the film falls when the film is opened.
