Description

本発明は、ビニールハウスのビニールを開閉するための機構、装置に関するものである。   The present invention relates to a mechanism and device for opening and closing vinyl in a greenhouse.

ビニールハウスは寒冷期に温暖な空気を室内に保持して植物を栽培するのに効果的であるだけでなく、暑い時期には天井部に滞留する高温空気を排気部を設けることで室内換気を促進し夏野菜等の栽培にも効果的な設備である。すなわち上部の高温空気を逃がすことで下方にある側壁にもうけた窓や出入り口から涼しい外気を自然に取り込み好適な環境を保つことができるのである。農場等の大型ハウスであれば天井部に開閉自在の天窓やビニールの一部を開閉する機構を備えたものもあるが、設備的に大掛かりなものとなる。個人農家が多く使っている蒲鉾型の簡易形ビニールハウスは、一般に金属や合成樹脂製のパイプのような構造体をアーチ状に形成したものが所定間隔で設置された骨組みであって、その上にビニールシートが張られたものである。この蒲鉾型の簡易形ビニールハウスは屋根全体を一枚のビニールシートを強固な金具等を多数用いて骨組みに固定し覆うようにしているため、面積の広いシートを張るには多くの人手を要するという問題と共に、気候条件に合わせ当該屋根を開閉したいがそれを実行するのは構造的に極めて困難であるという問題があった。   The greenhouse is effective not only for cultivating plants by keeping warm air in the room during the cold season, but also for ventilating the room by providing exhaust air for the hot air staying in the ceiling during hot weather. It is an effective facility for promoting and growing summer vegetables. That is, by letting out the high temperature air in the upper part, it is possible to naturally take in cool outside air from the windows and doorways provided in the lower side wall and maintain a suitable environment. If it is a large house such as a farm, there are some that have a mechanism that opens and closes a part of the vinyl that can be opened and closed on the ceiling, but this is a large facility. The cocoon-shaped simplified greenhouses that are often used by private farmers are generally skeleton-like structures made of metal or synthetic resin pipes that are installed at predetermined intervals. A vinyl sheet is stretched on the back. This saddle-type simple greenhouse is designed to cover and cover the entire roof using a large number of rigid metal fittings, etc., to secure a large sheet. In addition to this problem, there is a problem that it is structurally extremely difficult to open and close the roof according to the climatic conditions, but to implement it.

この問題に鑑み、本出願人は、先に蒲鉾型等の簡易形ビニールハウスにおいて、ビニールシートの張りわたしと固定及び天井部分と側壁部の開閉操作を一人で実行できるビニールハウスの手動開閉装置を提供することを提示（特許文献１）し、特許第3642747号として登録された。この発明は、パイプ状構造体を骨組みとした蒲鉾型のビニールハウスにおいて、該ハウスの半円筒部分及び側壁を覆うビニールシートを棟に沿って半分に分け、両側の側壁部に該ビニールシートを巻き取るロールを設置すると共に、該ビニールシートの引き出し端部に取付けた引き出し用紐部材を巻き取るリールをそれぞれ反対側の側壁部に設置するようにしたものである。この方式でビニールシートの巻き取りと巻き上げを実施した場合、巻き取りシャフトが長くなると負荷の増加に従って撓み現象が生じ、ビニールシートの巻き取りや引き出し用紐部材を巻き取る複数のリールの位置に狂いが生じ、それぞれに無理な力が加わって、スムーズな駆動が出来なかったり、部材を痛めたりしてしまう不具合が認められた。また、引き出し用紐部材はビニールシートの端部に固定された引出し竿に結ばれてビニールシートを引き出すようにしていたが、ビニールシートは引張られると伸びる素材であるため、繰り返し使用する過程でビニールシートが局部的に伸び、ビニールシートが歪んできれいに巻き取りできず、巻き取りシャフトにかかる負荷が不均一になってスムーズな巻き取り駆動が出来なくなるという不具合も認められた。
特開２００２−７８４２３号公報 「ビニールハウスの手動開閉装置」平成１４年３月１９日公開 In view of this problem, the applicant of the present invention first installed a manual opening / closing device for a greenhouse in which a single type of greenhouse such as a bowl-shaped greenhouse can be used alone to perform tensioning and fixing of a vinyl sheet and opening / closing operations of a ceiling portion and a side wall portion. It was proposed to be provided (Patent Document 1) and registered as Japanese Patent No. 3642747. The present invention relates to a saddle-type plastic greenhouse that has a pipe-like structure as a framework, and divides the vinyl sheet covering the semi-cylindrical portion and the side wall of the house in half along the ridge, and winds the vinyl sheet on the side wall portions on both sides. In addition to installing a roll to be taken, reels for taking up a draw-out string member attached to the draw-out end portion of the vinyl sheet are respectively installed on the opposite side wall portions. When winding and winding a vinyl sheet with this method, if the winding shaft becomes longer, a bending phenomenon occurs as the load increases, and the position of multiple reels that wind up the vinyl sheet or wind up the drawout string member is distorted. As a result, an unreasonable force was applied to each of them, and a smooth drive could not be performed or the members were damaged. Also, the drawer string member was tied to a drawer cage fixed to the end of the vinyl sheet to pull out the vinyl sheet, but the vinyl sheet is a material that stretches when pulled, so the vinyl sheet is repeatedly used in the process of repeated use. There was also a problem that the sheet stretched locally, the vinyl sheet was distorted and could not be taken up neatly, and the load applied to the take-up shaft became uneven and smooth winding drive could not be performed.

図１に本発明の装置を適用したビニールハウスの１形態を示す。単純な蒲鉾型ハウスで出入り口が設置される両端壁面部は省き、アーチ形状のパイプ構造体とビニールシートの開閉機構だけを示している。ビニールハウスの手動開閉装置の構成と動作については特許文献１を参照して頂くとして、本発明の実施形態を説明する前に、ここではその概略を説明しておく。
このビニールハウスのシート開閉装置はパイプ状構造体１を骨組みとした蒲鉾型等のビニールハウスを棟に沿って半分に分けて覆うビニールシート２を巻き取るロール３を設置すると共に、該ビニールシート２の引き出し端部に取付けた引き出し用紐部材５を巻き取るリール４を側壁部に設置したものである。前記パイプ状構造体１に一体に形成されたガイド部またはパイプ状構造体１の管内部に引き出し用紐部材５が案内されて巻き取り繰り出しがなされる。ビニールシート２の先端部分を引出し竿６に固定し、前記構造体のパイプをレールとして該引出し竿６に構造体１と同じ間隔で配設されたローラ１７が走行するガイド機構形態が採られている。前記ガイド部材に案内される引き出し用紐部材５には帯状のものが使用され、素材は強化ビニールを用い糸が芯材として入った引っ張り強度の高いものが好ましい。 FIG. 1 shows one form of a greenhouse to which the apparatus of the present invention is applied. The walls of both ends where the doorway is installed in a simple vertical house are omitted, and only the opening and closing mechanism of the arch-shaped pipe structure and vinyl sheet is shown. Regarding the configuration and operation of a manual opening and closing device for a greenhouse, refer to Patent Document 1, and before describing an embodiment of the present invention, an outline thereof will be described.
The sheet opening and closing device of this greenhouse is provided with a roll 3 for winding up a vinyl sheet 2 that covers a half-walled vinyl house with a pipe-like structure 1 as a skeleton, and covers the vinyl sheet 2 in half. A reel 4 for winding the drawer string member 5 attached to the drawer end is installed on the side wall. The draw-out string member 5 is guided into the guide portion integrally formed with the pipe-like structure 1 or the pipe of the pipe-like structure 1, and the take-up is performed. A guide mechanism is adopted in which the leading end portion of the vinyl sheet 2 is fixed to a drawer rod 6 and the pipes of the structure are used as rails and rollers 17 arranged on the drawer rod 6 at the same interval as the structure 1 travel. Yes. A belt-like member is used for the draw-out string member 5 guided by the guide member, and a material having high tensile strength in which a reinforced vinyl is used and a thread is contained as a core material is preferable.

引き出し紐部材５用のリール４はパイプ状の構造体１と同じ間隔で回転シャフト８に固定され、該シャフト８の両端部はハウスの外側四隅に立てられた支柱７に取り付けられた軸受９により回転自在に設置され、一端部に取り付けられたハンドル１０によって回転駆動される。勿論これは手動ではなく電動形態であっても良い。引き出し操作がなされる。また、ビニールシート２を巻き付けるロール３もリール４と同様の形態でシャフト８に固定され、該シャフト８の両端部はハウスの外側四隅に立てられた支柱７に取り付けられた軸受９により回転自在に設置され、一端部に取り付けられたハンドル１０によって回転駆動される。図１に示した実施形態では上下に３段のハンドルを配置しており、上段がビニールシートの巻き取りロール用、中段が引き出し紐部材のリール用、そして下段は日照調整用のネット１１の巻き取り用である。上段のハンドル１０を回すと、手前側の棟に張られているビニールシート２をロール３に巻き取る動作となる。ロール３に巻き取られ開放状態となった状態でビニールシート２を張る動作は、反対側の棟にゆき中段のハンドル１０を回動する。すると、リール４が引き出し紐部材５を巻き取り、ロール３に巻き取られた状態のビニールシート２を引き出してパイプ部材１の上に張っていく。   The reel 4 for the drawer string member 5 is fixed to the rotary shaft 8 at the same interval as the pipe-like structure 1, and both ends of the shaft 8 are supported by bearings 9 attached to pillars 7 standing at the outer four corners of the house. It is rotatably installed and is driven to rotate by a handle 10 attached to one end. Of course, this may be an electric form instead of manual. A drawer operation is performed. The roll 3 around which the vinyl sheet 2 is wound is also fixed to the shaft 8 in the same manner as the reel 4, and both ends of the shaft 8 can be freely rotated by bearings 9 attached to the pillars 7 standing at the outer four corners of the house. It is installed and rotationally driven by a handle 10 attached to one end. In the embodiment shown in FIG. 1, three stages of handles are arranged on the upper and lower sides, the upper stage is for the winding roll of the vinyl sheet, the middle stage is for the reel of the drawstring member, and the lower stage is the winding of the net 11 for adjusting sunshine. It is taken. When the upper handle 10 is turned, the vinyl sheet 2 stretched on the front ridge is wound around the roll 3. In the state of being wound around the roll 3 and being in the open state, the operation of stretching the vinyl sheet 2 moves to the opposite ridge and rotates the middle handle 10. Then, the reel 4 winds up the drawer string member 5, pulls out the vinyl sheet 2 wound up by the roll 3, and stretches it on the pipe member 1.

前述したように、このハンドル１０を回動し、ビニールシート２をロール３に巻き付ける際、または引き出し紐部材５をリール４に巻き取る際に、負荷が掛かって、シャフト８が撓むことの不都合を解決することが本発明の目的である。
本発明のビニールハウスのシート開閉装置は、パイプ部材が適宜の間隔をおいて連設された蒲鉾形態のビニールハウス構造体の側壁部に、ビニールシート２を巻き取るロール３またはビニールシート引き出し用紐部材５を巻き取るリール４を設置したシャフト８を水平に維持する支承部材を、前記シャフト８の中央領域において前記パイプ部材１に取り付けられた構成を採るようにした。 As described above, when the handle 10 is rotated and the vinyl sheet 2 is wound around the roll 3 or when the drawer string member 5 is wound around the reel 4, a load is applied and the shaft 8 is bent. It is an object of the present invention to solve this problem.
The greenhouse sheet opening and closing device of the present invention includes a roll 3 for winding a vinyl sheet 2 or a vinyl sheet drawer string on a side wall portion of a bowl-shaped greenhouse structure in which pipe members are continuously arranged at an appropriate interval. The support member that maintains the shaft 8 on which the reel 4 that winds up the member 5 is installed horizontally is attached to the pipe member 1 in the central region of the shaft 8.

図２に示した部材１２はビニールシート２を巻き取るロール３を受け止め水平状態に支承する断面が半円形状の樋部材（図のＡ参照）である。プラスチック又はブリキ等の金属板で形成する。部材１３は前記樋部材１２をパイプ部材１に取り付ける部材であって、ここに示した例は図のＢにあるとおり樋部材１２を下から支えるＵ字状の受け部とブラケット部、端部にはパイプ部材１を握り込むホルダー部１３ａと締め付けネジ１３ｂとから成るもの（図のＣ：部分拡大図参照）であるが、要は樋部材１２を水平に安定してパイプ部材１に取り付ける部材であればよく、適宜の形態が設計できる。この実施例をパイプ部材１に取り付けた形態を図３に示す。取り付け部材１３のホルダー部１３ａにパイプ部材１を挟持させ、締め付けネジ１３ｂを締めて固定する。複数のパイプ部材１に取り付け部材１３を取り付け、そのＵ字状の受け部で樋部材１２を水平に支承させるようにする。Ｕ字状の受け部と樋部材１２の結合は接着又は溶接等適宜の方法でよいが、樋部材１２の内面に突部が生じないようにする固着法が望ましい。ビニールシート２を巻き込み、引き出しする際に該突部がシート面を引っかくことがないためである。また、ロール３に巻かれたシート２の厚さ寸法は巻かれた状態によって変化するので、巻かれたビニールシート２の最下端部が常に樋部材内面に接触して保持される形態を採るためにはシャフト８の両端部を支承する軸受９が支柱７に対して上下方向のみに厚さ変動分だけ移動可能な形態で取り付けられることが望ましい。樋部材１２によるロール３の水平保持が実現され、シャフト８の軸を水平に維持できスムーズな巻き取りと引き出しがなされる。   The member 12 shown in FIG. 2 is a scissors member (see A in the figure) having a semicircular cross section for receiving the roll 3 for winding the vinyl sheet 2 and supporting it in a horizontal state. It is made of a metal plate such as plastic or tinplate. The member 13 is a member for attaching the flange member 12 to the pipe member 1, and in the example shown here, as shown in B of the figure, a U-shaped receiving portion that supports the flange member 12 from below, a bracket portion, and an end portion. Is composed of a holder part 13a for gripping the pipe member 1 and a tightening screw 13b (see C: enlarged partial view in the figure). An appropriate form can be designed. A form in which this embodiment is attached to the pipe member 1 is shown in FIG. The pipe member 1 is clamped in the holder portion 13a of the attachment member 13, and the fastening screw 13b is fastened and fixed. The attachment member 13 is attached to the plurality of pipe members 1, and the flange member 12 is horizontally supported by the U-shaped receiving portion. The U-shaped receiving portion and the flange member 12 may be joined by an appropriate method such as adhesion or welding, but a fixing method that prevents a protrusion from occurring on the inner surface of the flange member 12 is desirable. This is because the protrusion does not scratch the sheet surface when the vinyl sheet 2 is rolled up and pulled out. In addition, since the thickness dimension of the sheet 2 wound around the roll 3 varies depending on the wound state, the bottom end of the wound vinyl sheet 2 is always held in contact with the inner surface of the flange member. It is desirable that the bearing 9 supporting both ends of the shaft 8 is attached to the support column 7 in such a manner that it can move only in the vertical direction by the thickness variation. The horizontal holding of the roll 3 by the collar member 12 is realized, and the shaft 8 can be kept horizontal, so that the winding and drawing can be smoothly performed.

次に、ビニールシート引き出し用紐部材５を巻き取るリール４を設置したシャフト８を水平に維持する支承部材の実施例を図４に示す。図のＡに示す例は板状体の両端部を直角に立ち上げコの字状とした支承部材１４で、該支承部材１４の両側の垂直部にシャフト８を貫通させる穴１４ａを穿設したものである。該支承部材１４の下面にはブラケット部が一体的に固着され、その反対側端部にはパイプ部材１を握り込むホルダー部１４ｂと締め付けネジ１４ｃが一体的に取り付けられている。この実施例をパイプ状構造体１に取り付けた形態を図５に示す。支承部材１４のホルダー部１４ｂにパイプ部材１を挟持させ、締め付けネジ１４ｃを締めて固定する。複数のパイプ状構造体１に支承部材１４を取り付け、貫通穴１４ａでシャフト８を受け水平に支承させるようにする。
図４のＢに示した支承部材１５は、パイプ部材１間の位置関係を安定強固にするハウスパイプ補強材を兼用したものである。図示されているように貫通穴１５ａを穿設した部材をほぼパイプ間隔で一体的に取り付けると共に、パイプ部材１の位置にあわせて穿設された穴１５ｂが配置されている。ハウスへの取付はこの穿設穴１５ｂに図中で示しているようにパイプ部材１（破線）に嵌め込んで溶接若しくは適宜の固定部材で水平に固着する。これによって、シャフト８は安定的に水平状態が維持されると共に、パイプ部材１の位置関係も安定して強固となる。 Next, FIG. 4 shows an embodiment of a support member for maintaining the shaft 8 on which the reel 4 for winding the string member 5 for drawing out the vinyl sheet is installed horizontally. The example shown in FIG. 2A is a support member 14 in which both ends of a plate-like body are raised at a right angle and a U-shape is formed, and holes 14 a through which the shaft 8 passes are formed in the vertical portions on both sides of the support member 14. Is. A bracket portion is integrally fixed to the lower surface of the support member 14, and a holder portion 14b for gripping the pipe member 1 and a fastening screw 14c are integrally attached to the opposite end portion thereof. A form in which this embodiment is attached to the pipe-like structure 1 is shown in FIG. The pipe member 1 is clamped by the holder part 14b of the support member 14, and the fastening screw 14c is fastened and fixed. A support member 14 is attached to the plurality of pipe-like structures 1 so that the shaft 8 is received and supported horizontally through the through holes 14a.
The support member 15 shown in FIG. 4B also serves as a house pipe reinforcing material that stabilizes and strengthens the positional relationship between the pipe members 1. As shown in the drawing, a member having a through hole 15a is integrally attached at a substantially pipe interval, and a hole 15b that is formed in accordance with the position of the pipe member 1 is disposed. As shown in the drawing, the hole 15b is fitted into the pipe member 1 (broken line) and is fixed horizontally by welding or an appropriate fixing member. As a result, the shaft 8 is stably maintained in a horizontal state, and the positional relationship of the pipe member 1 is also stable and strong.

次に、ハウスシートの補強について好ましい形態を図６に示す。スムーズなビニールシートの開閉動作を実現する機構としては、シートの巻き取りまたは引き出しをおこなう巻き取りシャフトが負荷によって撓むことを防ぐだけでなく、ビニールシート２が使用する過程で部分的に伸びて歪まないようにすることも重要な問題となる。そこで、本発明ではパイプ部材１と接触し摺動する部分には強化テープ１６が貼り付けられ、該強化テープの端部はシートの端辺において引き出し用紐部材５が連結される引き出し竿６に取り付けられているローラ１７に締結された構成を採用した。強化テープ１６は引張り強度と摩擦強度を備えたものであれば、市販の粘着テープを利用することができる。この構成を採用したことにより、ビニールシート２は水平に保たれたロール３に巻き取られる際に、引張り方向に所定間隔に張られた強化テープで補強されているため、シート２が部分的伸びることは無く均一に力が作用することとなり、安定して巻き取りがなされる。また、引き出しに際しては水平に保たれたシャフト８に固定されたリール４によって均一条件で巻かれる引き出し用紐部材５の引き出し力はシート２の端部の引出し竿６に構造体１と同じ間隔で配設されたローラ１７を介して引出し竿６に作用し、ビニールシート２を全体的に引き上げる力となって作用し、安定した引き出しを行う。この際、引張り方向に所定間隔に張られた強化テープで補強されているため、シート２が部分的伸びることは無く均一に力が作用することとなり、安定して巻き取りがなされることは巻き取りの際と同様である。しかも、シート２の巻き取りまたは引き出しをおこなう際には、パイプ部材１の上を摺動することになるが、この接触部分には強化テープ１６が貼り付けられているため、シートの摩耗が防止できるという効果をも奏する。   Next, a preferred embodiment for reinforcing the house sheet is shown in FIG. As a mechanism for smooth opening / closing operation of the vinyl sheet, not only does the winding shaft that winds or pulls out the sheet prevent bending due to the load, but the vinyl sheet 2 partially extends during the process of use. It is also an important issue to prevent distortion. Therefore, in the present invention, the reinforcing tape 16 is attached to the portion that comes into contact with and slides on the pipe member 1, and the end of the reinforcing tape is connected to the drawer rod 6 to which the drawer string member 5 is connected at the edge of the sheet. The structure fastened to the attached roller 17 was adopted. A commercially available adhesive tape can be used as long as the reinforcing tape 16 has tensile strength and friction strength. By adopting this configuration, the vinyl sheet 2 is reinforced with the reinforcing tape stretched at a predetermined interval in the pulling direction when the vinyl sheet 2 is wound around the horizontally-maintained roll 3, so that the sheet 2 partially extends. Therefore, the force acts uniformly and the winding is stably performed. Further, when pulling out, the pulling-out force of the pull-out cord member 5 wound under uniform conditions by the reel 4 fixed to the shaft 8 kept horizontal is applied to the pull-out bar 6 at the end of the sheet 2 at the same interval as the structure 1. It acts on the drawer trough 6 through the arranged roller 17 and acts as a force for pulling up the vinyl sheet 2 as a whole, thereby performing a stable drawer. At this time, since the sheet 2 is reinforced with a reinforcing tape stretched at a predetermined interval in the pulling direction, the sheet 2 does not partially extend and a force acts uniformly, and the winding is stably performed. It is the same as when taking. Moreover, when the sheet 2 is taken up or pulled out, it slides on the pipe member 1, but the reinforcing tape 16 is attached to this contact portion, so that the sheet is prevented from being worn. There is also an effect of being able to.

本発明は、農業用のビニールハウスを想定して説明してきたが、本発明のシート巻き取り機構はそれに限らず、他のシート部材の巻き取り、引き出し機構、例えば先の特許文献１で紹介した家屋の雪下ろし装置にも応用できる。   The present invention has been described assuming an agricultural greenhouse. However, the sheet winding mechanism of the present invention is not limited thereto, and other sheet member winding and pulling mechanisms, for example, introduced in Patent Document 1 above. It can also be applied to snow removal equipment for houses.
