本考案は温室内で保温用仕切りカーテン又は開
閉可能な外被として張設されるプラスチツクシー
ト等を巻取り巻戻して開閉するための装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for winding up, unwinding, and opening/closing a plastic sheet or the like stretched as a heat-retaining partition curtain or an openable/closeable outer covering in a greenhouse.
例えば一般に、長尺な仕切カーテンの一端を傾
斜仕切面の上部フレームに固着し、他端縁に巻取
軸を固定してこの巻取軸を適宜の駆動源により回
転転動せしめることにより、該カーテンを巻き上

下方へ巻戻し閉成することが行われている。この
開閉方法においては仕切面が十分な傾斜角度がな
ければ適確なカーテン巻戻し閉成が行えないもの
である。すなわち、傾斜角度が小さいとき又は水
平であるときには巻取軸の自重による低位への転
動がないので、カーテン巻戻しのために巻取軸を
単に逆転駆動しても、ロール状巻取り部の内部で
巻取軸が空転するだけで転動力が与えられない。 For example, in general, one end of a long partition curtain is fixed to the upper frame of the inclined partition surface, a winding shaft is fixed to the other end edge, and this winding shaft is rotated and rolled by an appropriate driving source. The curtain is rolled up, opened, and then reversed to be rolled back downward and closed. In this opening/closing method, the curtain cannot be rewinded and closed properly unless the partition surface has a sufficient inclination angle. In other words, when the angle of inclination is small or horizontal, the winding shaft does not roll downward due to its own weight, so even if the winding shaft is simply driven in the reverse direction for curtain rewinding, the roll winding section will not roll. The winding shaft simply spins idly inside, and no rolling force is applied.
そこで、この巻取軸の逆転と同時に転動移動の
ための手段が必要となるが、巻取軸の回転数は一

ーテンは用途に応じたフイルムの厚薄、温室サイ
ズに応じた長短等千差万別であるので、巻取径の
変化も一定でない。 Therefore, a means for rolling movement is required at the same time as this reversal of the winding shaft, but while the rotation speed of the winding shaft is constant, rolling movement changes as the winding diameter decreases. Therefore, it is difficult to match the rotation and movement speed of the take-up shaft without causing the curtain to become smeared or smeared. In particular, greenhouse curtains vary in thickness depending on the purpose, length, etc. depending on the size of the greenhouse, so the change in the winding diameter is not constant.

An output shaft 714 rotatably supported within the casing 12 is a main shaft for a spring, and is rotatably supported within the casing 712. Reference numeral 715 denotes a constant spiral spring, one end of which is fixed to the output shaft 713 so that it can be tightly wound, and the other end is not fixed to the spring main shaft 714 but is tightly wound. 713' and 714' are flange parts fixed to the output shaft 713 and the main shaft 714, respectively;
In order to wind the mainspring spring 715 in an aligned manner, it is provided as necessary. 716 is an auxiliary shaft, 717 is an auxiliary drum, and the rewinding wire 72 is fixedly wound around the auxiliary drum 717. However, it goes without saying that the rewinding wire 72 may be wound directly around the output shaft 711 without providing the auxiliary shaft 716 and the auxiliary drum 717. In addition to installing one infinitesimal mainspring spring 715 as shown in FIG. 3, two indefinites mainspring springs 71 as shown in FIG.
5a, 715b, or three or more are design changes included in the present invention.
To install multiple indeterminate number springs, please refer to the fourth step.
As shown in the figure, one end of each is provided so as to overlap and wrap around the output shaft 713.

In this case, one end of each of the unwinding wires 72a, 72b, 72c, . . When provided in this manner, there is also the effect of peeling off the clasp of the roll-shaped winding portion when unwinding the curtain. Also, depending on the size of the greenhouse and the thickness of the curtains, it is possible to provide multiple drive sources, for example, the auxiliary shaft 7.
One 71, 71a may be installed at each end of the auxiliary shaft 16, or may be installed at the middle of the auxiliary shaft.

カーテン３に無理なテンシヨン増加が生じないの
で、破損事故を生じることがない。 Now, when the prime mover M rotates and urges the winding shaft 4 in the direction of the arrow r in FIG. do. At this time, the unwinding wire 72 is wound around the winding shaft 4 and pulled in the rolling direction of the winding shaft, so that the drive source 7
The auxiliary drum 717, the auxiliary shaft 716, and the output shaft 711 of No. 1 are rotated in the direction of arrow S in FIG. Due to this rotation of the output shaft 711, the indefinite mainspring spring 715 is extracted from the main shaft 714 and wound around the output shaft 711. In this process, the above-mentioned indeterminate mainspring spring 715 is attached to the winding shaft 4.
The winding torque of is applied, but the spring constant of the inconstant mainspring spring 715 is zero or close to zero,
Since it is a spiral spring that can obtain a constant output/torque, the winding torque is always constant until the extraction from the main shaft 714 is completed. Therefore,
Since an unreasonable tension increase does not occur in the curtain 3, damage accidents do not occur.
次いで、原動機Ｍを逆転せしめると巻取軸４は

るものである。 Next, when the prime mover M is reversed, the winding shaft 4 rotates in the direction opposite to the arrow r to unwind the curtain 3. Then, the winding shaft 4 receives the action of the winding torque of the indeterminate mainspring spring 715, and the drive source 7
being pulled in one direction. At this time, the winding shaft 4 is given a constant rotational speed by the reducer 52, but the moving speed decreases due to the decrease in the winding diameter. However, even if the moving speed of the winding shaft 4 changes, the winding torque of the infinite spiral spring 715 is kept constant, so the unwinding wire 72 pulls the winding shaft 4 with almost constant tension. be able to. Therefore, the curtain 3 to be rewound can be properly closed without causing any loosening or sagging on the partition surface, and without being subjected to excessive tension.
尚、温室側窓又は天窓の仕切面に張設される外
