First, as shown in FIG. 4A, the horizontal slide 21 is located at the left end of the horizontal guide shaft 10, the suspension 28 is deployed, and the vertical slide 24 is located at the lowest position. At this time, the vinyl sheet 27 is wound to the maximum extent on the winding shaft 26, and the vinyl sheet 27 that has not been wound is folded below the vinyl sheet 27.

When the first and third motors 22 and 38 are started at the same time, the slide shaft 20 rotates to take up the suspended body 28 and pull up the take-up shaft 26. As a result, the winding shaft 26 rises while rotating the folded vinyl sheet 27 without rotating. And
The vertical slide 24 contacts the limit switch provided on the vertical guide shaft 23, and the first motor 22 stops. On the other hand, the drive shaft 37 rotates, and one end of the driving wire rope 33 is wound on the winding drum 36 integrated therewith, and at the same time, the driving wire rope 33 wound on the winding drum 36 is rotated. The end is pulled out. Therefore, the driving wire rope 33 pulls the driving body 32,
The slide shaft 20 moves to the column 12 side. A weight 41 such as soil or stone is placed on one edge of the vinyl sheet 27 so as not to be displaced.

Then, as shown in FIG. 4 (b), when the horizontal slide body 21 reaches near the center of the horizontal guide shaft 10, that is, when the winding shaft 26 reaches between the ridges 42a and 42b,
The third motor 38 is stopped. Then, when the first motor 22 is rotated in the reverse direction and the suspended body 28 is extended, FIG.
As shown in FIG.
And descends until it stops by contacting the limit switch provided in the. For this reason, the vinyl sheet 27 covers the seedlings along the arched frame 43a erected on the ridge 42a.

Next, the first, second and third motors 2
2, 25 and 38 are driven simultaneously. As a result, the slide shaft 20 rotates to wind up the hanging body 28 and the winding shaft 26 is pulled up, and at the same time, the winding shaft 26 rotates to expand the wound vinyl sheet 27. Then, the vertical slide body 24 comes into contact with a limit switch provided on the vertical slide shaft 23, and the winding shaft 26 moves up until the first motor 22 stops. Further, the drive shaft 37 rotates, and one end of the driving wire rope 33 is wound on the winding drum 36, while the other end of the driving wire rope 33 wound on the winding drum 36 is pulled out. . For this reason, when the driving wire rope 33 pulls the driving body 32 and the slide shaft 20 moves to the column 12, the slide shaft 20 reaches the other end of the horizontal guide shaft 10 (FIG. 5B). When the limit switch provided on the slide body 21 comes into contact with the support 12,
The third motors 25 and 38 stop.

When the first motor 22 is rotated in the reverse direction and the hanging body 28 is unwound, the winding shaft 26 is lowered, and the vinyl sheet 27 is moved along the arched frame 43b.
2b (FIG. 6). Thereby, the vinyl sheet 27
Is formed, and the sheet hanging operation is completed. However, since both ends of the tunnel formed by the vinyl sheet 27 are covered with the vinyl sheet 27 for a long time, they are closed by the weight of the vinyl sheet 27. Alternatively, another vinyl sheet may be placed only on the frames located at both ends of the ridge 42a, and only the seedlings at both ends may be covered in advance.

The vinyl sheet 27 is taken up and the ridges 42
To open the terminals a and 42b, the above-described operation may be performed in reverse. Further, while winding up the vinyl sheet 27 with the winding shaft 26, the winding shaft 26 is pulled up through the hanging body 28, and further, the slide shaft 20 is
May be directly returned to the support 11 side.

FIG. 7 shows a second embodiment whose basic configuration is almost the same as the first embodiment. In the present embodiment, as the horizontal guide shaft 10, a section steel having a substantially C-shaped cross section is used, and the horizontal slide body 21 can be slid via two roller wheels (not shown) fitted into the concave portions. It is attached. Then, when the slide shaft 20 is rotated via the first motor 22 attached to the horizontal slide body 21, the wide tape-shaped hanging body 28 is wound up, and a winding shaft 26 described later is pulled up. Further, the slide shaft 20 is driven by a drive wire rope 33 and a guide wire rope 34 via a pulley 32c fixed to a bearing 31 disposed at a predetermined interval on the slide shaft 20.

A vertical guide shaft 23 is hung on the bottom surface of the horizontal slide body 21 via a hinge joint 21a so as to be swingable in the moving direction. This vertical guide shaft 23 is connected to a winding shaft 26 via a vertical slide 24.
It is hung over both ends. In this vertical guide body 24,
In order to reduce friction with the vertical guide shaft 23, rollers 24a
Is attached. And this vertical slide 2
When the second motor 25 attached to the motor 4 is rotated, the rotation shaft of the second motor 25 contacts the vertical guide shaft 23 and rotates, and the winding shaft 26 rotates. Thereby, the winding shaft 26 winds the vinyl sheet 27 and the hanging body 28 at the same time.

Further, a pulley 21c is suspended from the horizontal slide body 20 via suspension pieces 21b.
A wire 45 is hung on the pulley 21c, and one end of the wire 45 is fixed to the second motor 25, and a weight 4 is attached to the other end.
6 is hung. This is to reduce the bending moment generated on the winding shaft 26 by the weight of the second motor 25 and uniformly wind the vinyl sheet 27. The weight 46 is slidably housed in a cylindrical body 47 suspended by the suspension pieces 21b. This is to prevent the weight 46 from being caught on the second motor 25 or the like that moves up and down.

The horizontal slide 21 has a roller wheel 21b attached to the upper edge thereof. This is to prevent the horizontal slide body 21 from being easily caught by the horizontal guide shaft 10 due to the bending moment based on the weight of the slide shaft 20 and the vinyl sheet 27, and to prevent the horizontal slide body 21 from operating smoothly. Note that a driving wire rope may be attached to the horizontal slide body 21 for direct driving.

FIGS. 8 to 10 show a third embodiment of the present invention. In the above-described embodiment, two slide shafts are used, while one slide shaft is used. The driving means 30 is the same as that of the above-described embodiment, and is not shown for convenience of description. In the present embodiment, two slide shafts 50a and 50b (the slide shaft 50b is not shown) are connected to the drive and guide wire ropes 33 and 34, which are horizontal guide shafts, via horizontal slide bodies 51a and 51b. It is. This horizontal slide 51
The vertical guide shaft, the vertical slide body, and the like as in the above-described embodiment are not suspended from a and 51b. Therefore, by rotating the slide shafts 50a and 50b and winding up the suspension bodies 53a and 53b,
The winding shafts 54a and 54b to which the vinyl sheet 27 is attached are pulled up via the packer 55.

As an operation method, for example, as shown in FIG. 8 and FIG.
b motors 52a and 52b are rotated to suspend
a and 53b are wound up, and the winding shafts 54a and 54b are pulled up. Next, the slide shafts 50a and 50b are moved to respective predetermined positions (FIG. 9A). Finally, the motors 52a and 52b are rotated in reverse to suspend the bodies 53a and 53b.
And cover the ridges 42a and 42b with the vinyl sheet 27.

In this embodiment, two horizontal slides 5
Although the case where 0a and 50b are moved has been described, the present invention is not necessarily limited to this, and three or more horizontal slide bodies may be attached and slid simultaneously. Therefore, according to the present embodiment, there is an advantage that it can be applied to a greenhouse having a wide frontage with a smaller number of parts than the above-described embodiment.

In the above-mentioned operation method, the operation method using the limit switch has been described. However, the present invention is not limited to this, and all the automatic control may be performed by combining the limit switch and the microcomputer. Further, in order to prevent the vinyl sheet covering the ridges from rising along the arched frame, an elongated rod-shaped weight is fixed on the surface of the vinyl sheet at a predetermined interval so as to be parallel to the winding axis. Is also good. As a result, there is an advantage that the lifting of the vinyl sheet is eliminated, and the work of placing a weight such as soil or stone on the edge or intermediate portion of the vinyl sheet can be omitted.

[0032]

As is apparent from the above description, according to the sheet hanging apparatus of the first aspect of the present invention, the take-up shaft extends along the vertical guide shaft suspended from both ends of the reciprocally movable slide shaft. Moves up and down, and further turns to unfold or wind the sheet. For this reason, the sheet hanging work on the ridge can be mechanized, and the labor can be reduced. According to the second aspect, the weight is lifted by the weight via the wire attached to one end of the winding shaft. Therefore, even when a motor or the like is attached to one end of the winding shaft, the vinyl sheet can be uniformly wound around the winding shaft by reducing the bending of the winding shaft caused by the motor or the like. According to the third aspect, the structure is simplified and the number of parts is small.
The ridges of a greenhouse with a wider frontage can be automatically covered with the sheet. According to the fourth aspect, since the horizontal guide shaft is a wire rope, the moving distance of the slide shaft can be easily changed as necessary, and the slide shaft can be moved smoothly without requiring high assembly accuracy. Can be done. According to the fifth aspect, the slide shaft can be reciprocated via the wire rope. Therefore, by adjusting the length of the wire rope, the slide distance can be easily changed as required, and the slide shaft can be smoothly slid without requiring high assembly accuracy. According to the sixth aspect, the stick-shaped weight provided on the surface of the sheet can prevent the sheet from rising and shifting. For this reason, there is no need to place a weight such as soil or stone on the sheet, and there is an effect that labor can be further saved.
