Description

  The present invention relates to a greenhouse sheet winder for roofs which can be operated in a stable state without rolling up and unwinding the greenhouse sheet.

  The greenhouse for plant cultivation is covered with a vinyl sheet on the ceiling, side surface, and wife surface, and the sheet can be freely opened and closed so as to be shielded from light, air circulation, temperature adjustment, and the like. As a general one, there is known one in which a winding device is attached to a column fixed near the outside of a greenhouse so as to be movable in the vertical direction. This take-up device is a mechanism in which when the handle is operated, the take-up shaft on which the sheet is wound rotates forward and backward to take up and rewind the sheet, thereby opening and closing the required part of the greenhouse. The technique has been followed from the old to the present, but when manually turning the handle, it does not necessarily operate smoothly depending on the size of the greenhouse, the height, the height, it requires skill in operation, and the opening and closing of the seat There are a number of problems that are not as easy as expected.

  For the purpose of solving such problems, for example, Patent Document 1 proposes a joint member for a vinyl sheet opening / closing device of a greenhouse, and Patent Document 2 discloses a winder sheet winding device.

Utility Model Registration No. 3152740 JP 2002-101767 A

  The technique disclosed in Patent Document 1 relates to a joint structure of a sheet winding device that can easily perform a handle operation. A flexible packing member is inserted into the upper and lower cylindrical bodies to operate the handle. When the drive pipe is moved, the lower cylindrical body tilts in the same direction as the drive pipe with the upper cylindrical body as a fulcrum, so the handle operation connected to the drive pipe is smooth and even a long drive pipe is easier than before It is characterized by being able to move. Although this technology has the advantage that the steering wheel can be operated even when the drive pipe is tilted with respect to the vertical greenhouse wall surface, for example, when the curtain film of the greenhouse is stretched at the height of the roof, it undulates depending on the air volume and direction. In such a situation, there is no solution to the problem of being able to cope with an unexpected situation where the drive pipe is shaken and the opening and closing of the drive pipe is hindered.

  The winding device shown in Patent Document 2 reduces the operating force required during the winding operation. For this purpose, the handle is provided so that it can be extended and retracted. By rotating the handle while the handle is extended, Although it is characterized by a large turning radius, according to this technology, the speed at which the sheet is rolled up and the speed at which the sheet is rewound are set to be the same, so the time required for rewinding becomes long, and Depending on the length of the arm of the handle, there is a problem that it is easy to touch the operator's body and is difficult to operate.

  As seen in the prior art described above, from the viewpoint of improving the operability of the handle, it is considered possible to achieve the desired effect, but on the other hand, from the viewpoint of smooth and reliable opening and closing of the roof curtain film Then, it is not made a thing with sufficient function yet.

  The present invention has been made in view of such a conventional technique, and can open and close the seat without requiring skill because it can be easily wound and rewound without burdening the operator even though it is a conventional handle operation. It is of course possible to provide a sheet take-up device that can operate the take-up shaft stably without raising the curtain film regardless of the height of the curtain for the roof or the weight of the film, and the wind direction. Is intended.

  For this purpose, the present invention is provided with a casing incorporating a rotation transmission means between the input shaft and the output shaft, the input shaft is interlocked with the operating rod via a flexible joint fitting, and the output shaft is wound around the seat. In a sheet winding device in which a winding shaft is inserted, a guide pipe that is linked to an operation rod is inserted into a tiltable support that is attached to the side of the casing, and a bearing in which one end of the guide pipe is fixed to a greenhouse is used as a fulcrum. It is movable and maintains the balance of the operation rod.

  When the casing is moved up and down by the operation of the handle and the take-up shaft rotates and the curtain is opened and closed, the support located on the side of the casing is interlocked. At this time, the guide pipe inserted through the support uses the bearing as a fulcrum. Since the casing tilts and moves in a predetermined manner, the casing reliably opens and closes regardless of the weight of the curtain, the wind direction, and the air volume. In other words, in the case of a curtain with an R shape at a greenhouse height, the operation rod becomes long and unstable, and there has been a problem in the conventional opening and closing, but the balance is maintained by the presence of the guide pipe, and such concerns are wiped out. Is done.

It is an attachment state figure of the present invention. It is a front view which shows the principal part of this invention. It is a side view same as the above. It is the schematic which showed the motion of this invention with the arrow.

  An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, a curtain film 2 (hereinafter referred to as a film) that can be opened and closed is hung on an R-shaped roof portion of a greenhouse 1. Similarly, when the handle 8 at the end of the operating rod 7 is turned, the take-up shaft 4 inserted into the casing 3 is moved and taken up and rewound. A rotation transmitting means for transmitting the movement of the input shaft 5 to the output shaft 6 is incorporated in the casing 3, and the winding shaft 4 is inserted into the output shaft 6. In addition, since the rotation transmission means in the casing employs a gear mechanism or the like having a conventional configuration and is not particularly new, the drawings and explanations are omitted.

  Reference numeral 9 denotes a symmetrical joint fitting made of upper and lower halves 10 and 10 ′, which has a bending material (not shown) such as a wire and a spring member, and is fixed to the input shaft 5. The lower half 10 is tilted and rotated with respect to the upper half 10 in accordance with the movement of the operating rod 7, but these configurations also adopt a conventional well-known technique. That is, the winding and rewinding operation of the film 2 is performed by turning the handle 9 at the lower end of the operation rod 7, and the lower half 10 ′ of the joint fitting 9 is changed to the upper half 10 according to the operator's standing position. It exhibits the function of tilting and turning around the fulcrum.

  Reference numeral 11 denotes a tiltable support device attached to the side surface of the casing 3, and a guide pipe 12 is inserted through the support tool 11. The support 11 is engaged with a fixed shaft 13 projecting from the casing 3 so as to freely rotate and tilt within a predetermined range, so that the guide pipe 12 tilts together with the support 11. Since one end of the guide pipe 12 is movable with a bearing 14 fixed to the greenhouse as a fulcrum, the movement is always constant, and the movement of the casing 3 is balanced.

  In order to make the movement of the guide pipe 12 smooth, an abacus-shaped roller (not shown) is incorporated in the support 11 so as to sandwich the guide pipe 12 from the left and right and front and rear. By doing so, the roller rotates each time the guide pipe 12 moves in the support 11, and the guide pipe 12 can be moved smoothly.

  A general side winder has a fixed guide part to suppress the rewinding of the curtain film. However, it is difficult to install the guide in the conventional technology because the place where the handle is attached differs between the side and the roof. Although the disadvantage that blurring occurs when the operating rod used for roofing is pushed up is not solved, in the present invention, the guide pipe 12 interlocked with the movement of the casing 3 prevents the casing 3 from moving loosely and is not unwound unexpectedly during winding. Can be.

  FIG. 4 shows an example of the movement of the casing 3 and the guide pipe 12. When the handle 8 is turned, the operation rod 7 rotates, and the casing 3 rotates along the R-shaped greenhouse roof while rotating the winding shaft 4. Move in the direction to close the film 2. At that time, as the casing 3 goes to a high place, the support 11 is also raised, and the guide pipe 12 moves in the support 11 and the bearing 11 is inclined to the fulcrum.

  When the handle 8 is turned in the opposite direction, the casing 3 moves toward the lower side of the greenhouse roof while winding the film 2, and the guide pipe tilts with the 12 bearings 14 as fulcrums accordingly. That is, the guide pipe 12 tilts with the bearing 14 as a fulcrum during rotation of the winding shaft 4 that moves together with the casing 3, so that the casing 3, the joint fitting 9, and the operation rod 7 can be operated even when external pressure such as the weight of the curtain film 2 or wind pressure is applied. The movement of the curtain moves smoothly as if the curtain is opened and closed because it operates accurately as a link mechanism.

  As described above, the present invention is not suitable for a side film of a greenhouse because it is a winder for winding a curtain film for a roof of a greenhouse. Therefore, in FIG. It is a thing.

  In the present embodiment, a greenhouse is illustrated as an example. However, in the case where several buildings are arranged in the horizontal direction, it is needless to say that a similar device is provided for each, and is shown in the range where the object effect of the present invention is achieved. Combinations and configurations of members other than the above also belong to the category of implementation of the present invention.
