DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film winding device for a house, and more particularly to a film winding device for a house for automatically winding a film of a cultivation house.

[0002]

2. Description of the Related Art A house used for cultivating a house is an agricultural film mainly composed of a polyolefin resin or a vinyl chloride resin, which is spread on a framework constituting the house. When cultivating vegetables in such a house, a part of the film is wound up to introduce outside air into the house for ventilation or temperature adjustment. With such a measure, it is possible to prevent the temperature inside the house from becoming too high, and to easily control the temperature inside the house.

[0003] The applicant of the present invention has disclosed in,
No. 6747 proposes a structure in which a winding film covering an opening on the side surface of a house is wound by a winding shaft to form an opening on the side surface to allow air to flow to the outside.

[0004]

A conventional apparatus for opening and closing the side of a house by winding up a film for a house is known as a manual apparatus in which a side film is manually lifted up or a direct connection to a winding shaft is made when ventilating. It is common to open and close using a hoisting opening and closing tool. In the case of managing a large number of houses, the working time for opening and closing the film becomes longer, the temperature control in the house becomes uneven, and as a result, the growth of cultivated crops in the house becomes uneven. In addition, it is not possible to cope with sudden changes in the weather, which may delay the growth of some crops or impair the quality of the crops. In addition, in a time when minute and minute responses are required, there is an inconvenience that the house cannot be vacated or that it is difficult to cultivate a house in a cultivation place far from the house.

To solve such inconvenience, an automatic hoisting opening and closing device has been proposed, but the proposed device has not been actually used due to the following problems.

[0006] b. A hoisting opening / closing device has been developed in which a motor for winding the film is suspended by a wire to supplement the weight of the motor, or a weight is provided to maintain the balance. However, in such a device, if the wire is extended for a long period of time, or if the wire is loosely fixed, the hoisting motor will run idle. . For this reason, there was a problem that the cost for installing a strong support was increased. In addition, according to such a method, there is a problem that the house cannot be opened and closed on a curved surface or an inclined surface.

[0007] b. Because the film winding motor for the house uses a switch that is heavy and stops upon contact,
There was a disadvantage that the stop position was likely to shift due to the strong contact of the hoisting motor with the stopper. As a countermeasure, the stopper is fixed using an iron plate firmly fixed with screws or the like. Then, on the contrary, there is a problem that it is difficult to easily move and adjust the position of the stopper. Further, if a complicated electric circuit is designed to prevent this and the drive control of the motor is performed by using such a circuit, there is a disadvantage that it is expensive and the handling becomes too complicated.

C. In many cases, the installation place of the cultivation house is far away from the cultivation manager's house. The cultivation house is not wired with a commercial power supply. Therefore, even if the electric hoist is provided, the electric hoist cannot be used unless the electric pole and electric wire for supplying commercial power are installed.

D. When attaching or detaching a hoisting motor or a manual hoisting tool to or from the hoisting pipe, there is a strong force to push the hoisting pipe of the installed hoisting film, making it difficult to disconnect or install the joint that connects the hoisting pipe. It is difficult to change the film easily, and there is a problem in that if the work is forcibly performed, the wound film is damaged or the installation position is distorted.

E. When using a device that opens and closes the lining film on both sides, there is little convection of the air, and in places exposed to the west sun, the temperature inside the polymerized film that is moved aside and stored abnormally . That is, even though the temperature in the house is 35 ° C., the temperature immediately above the polymerized film becomes 90 ° C. or more, and the film aside is blocked, and the opening / closing device does not work. There is a problem of breaking.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is possible to automatically open and close a house film and easily change the open / close position as needed. It is an object of the present invention to provide a film winding device for a house.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a cultivation house provided with a house film winding device according to one embodiment of the present invention. The cultivation house is obtained by spreading an agricultural film on the arched frame 10. That is, the side of the house is covered with the film 11 for a house. Moreover, a rectangular opening 12 is formed on the side surface, and such an opening 12 is openably and closably covered with another house film 15.

The lower end of the film 15 for a house is fixed to a take-up shaft 16, and the film 15 for a house on the take-up shaft 16 is pressed by a holding string 17 at an arbitrary take-up position. . In addition, presser cord 17
Is held down by the lower part of the side of the house.

The opening and closing of the opening 12 by the house film 15 is achieved by an elevating unit 22 on a pair of left and right guide posts 21 arranged near the corner on the wife side of the house 10. As shown in FIGS. 2 and 3, a drive motor 23 and a speed reducer 24 are incorporated in the elevating unit 22, and an output shaft 25 of the speed reducer 24 is connected via a sleeve joint 26 to the house film 1.
5 is connected to the take-up shaft 16.

The lifting unit 22 has four support shafts 29.
The rolling wheels 30 are rotatably mounted by the support shafts 29, respectively. The rolling wheel 30 has a substantially semicircular guide groove 31.
As a result, the rolling wheel 30 rolls on the outer peripheral surface of the guide column 21, whereby the lifting unit 22 moves up and down on the guide column 21.

That is, two pairs of rolling wheels 30 having guide grooves 31 substantially equal to the radius of the guide posts 21 are arranged inside the elevating unit 22, and a drive motor 23 having a speed reducer 24 having an appropriate speed reduction ratio. Is provided. In addition, a non-contact proximity switch 47 that senses a gap of, for example, about 1 cm is provided on the upper surface of the elevating unit 22. The output shaft 25 projecting from one side of the elevating unit 22 and the winding shaft 16 are connected by a sleeve joint 26 which can be removed by sliding in the axial direction.

Next, the stoppers 35 attached to the upper and lower limit positions of the elevating unit 22 on the guide column 21 are substantially horseshoe-shaped as shown in FIG. Is linked to The holder 37 is attached so as to embrace the guide column 21 from outside.

That is, a stopper 35 which appropriately sandwiches the guide column 21 and has a sensing surface of a non-contact proximity switch 47 of an appropriate size, and a fitting portion 37 which is fitted into the guide column 21 and fixed detachably. Stopper 35 made of stainless steel and provided with a connecting portion 36 for connecting
Is provided. And the guide support 21 provided on the hoisting wife surface
The upper and lower stoppers 35 are fixed to the guide column 21 at the holder 37 so that the upper and lower stoppers 35 are opposed to each other at the upper limit position and the lower limit position where the opening and closing are to be performed. .

The elevating unit 22 is attached to the guide column 21 in a skewered manner between the upper and lower stoppers 35. Here, the output shaft 25 of the elevating unit 22 is directly connected to the winding shaft 16 of the film for house 15 by a joint 26. As a result, the film winding device is assembled.

The left and right lifting units 22 are shown in FIG.
Is connected to the control panel 40 as shown in FIG. A battery 41 and a solar cell 42 are further connected to the control panel 40. Further, a temperature sensor 43 for detecting the temperature in the house and a raindrop sensor 44 attached to the upper end of the guide column 21 are connected to the control panel 40.

When a commercial AC power supply is used, it is converted to DC 24V by a transformer in the control panel 40 and used. When a commercial AC power supply cannot be used, a 24 V battery 41 and a solar cell 42 are used as power supplies. In this way, not only can the film opening / closing device for the house film 15 be opened and closed by a manual switch, but also automatically opened and closed as needed using the temperature sensor 43 and the raindrop sensor 44. .

That is, when the temperature sensor 43 detects that the temperature inside the house has risen, the control panel 40 supplies power from the battery 41 to the drive motor 23 of the lifting unit 22. Thus, the motor 23 is driven to rotate. The output rotation of the motor 23 is reduced by a speed reducer 24, and the winding shaft 16 is rotationally driven through an output shaft 25 in a direction in which the house film 15 is wound.

Accordingly, the film 15 for a house is wound up, and at this time, the winding shaft 16 moves upward on the arched frame 10 along the side surface of the house.
Accordingly, in response to such a movement, the elevating unit 22 connected to the winding shaft 16 slowly moves upward along the guide column 21. When the lifting unit 22 moves up to the vicinity of the upper stopper 35, the non-contact proximity switch 47 detects the stopper 35. Then control panel 40
Stops supplying power to the drive motor 23, and the motor 23 stops at this position. Accordingly, the house film 15 is wound up with the side opening 12 opened.

If the temperature sensor 43 detects that the temperature in the house has dropped below a predetermined temperature,
The control panel 40 supplies power to the drive motor 23 and rotates the motor 23 in the reverse direction. Accordingly, the output shaft 25 of the speed reducer 24 is rotated in the direction in which the winding shaft 16 feeds out the film 15 for a house.

Therefore, the winding shaft 16 descends while rolling gently on the side of the house. Therefore, the lifting unit 2
2 moves quietly downward along the guide column 21. Then, when the lower stopper 35 is detected by the non-contact proximity switch 47, the control panel 40 stops supplying power to the drive motor 23 at that position. Therefore, at that position, the motor 23 stops, and the unfolded house film 15
Thereby, the opening 12 is closed.

Next, another embodiment will be described with reference to FIG. In this embodiment, a guide post 21 is provided in a house along a frame of the house, and a lining curtain is wound by an elevating unit 22 that moves along the guide post 21. That is, an elevating unit 22 is attached to the guide column 21 in a skewered manner. The unit 22 allows the winding shaft 16 to wind up or out of the winding shaft 16 to open and close the side curtain. Is performed.

In this case as well, it is possible to mount the stopper 35 at each of the upper limit position and the lower limit position, and further attach a timer and a temperature sensor so that the opening and closing operation can be performed without manual operation using a battery or a solar cell as a power supply. is there.

Next, still another embodiment will be described with reference to FIG. In this embodiment, the lower end of the holding string 17 for holding the wound film for house 15 is held by the holding string winding shaft 5.
1 and the presser string winding shaft 51
Is rotatably supported by a bearing ring 52 disposed below the side end of the house, and the end of the presser string winding shaft 51 is connected to a winding shaft driving motor 53.

That is, here, a bearing ring 52 is provided at an appropriate position on the side surface of the house to rotatably support the presser string winding shaft 51, and furthermore, this winding shaft 51 is connected to the motor 53, so that the presser string winding The holding string 17 is fixed to the shaft 51. Then, the winding shaft driving motor 53 is driven to rotate in conjunction with the winding of the house film 15 by the driving motor 23 of the lifting unit 22, and the presser string 17 wound around the presser string winding shaft 51 is loosened. Thus, winding and fixing of the house film 15 are smoothly performed. Therefore, according to such a configuration, the holding string 17 does not become a load when the opening 12 is opened and closed when the house film 15 is wound or fed.

Next, still another embodiment will be described with reference to FIG. In this embodiment, the guide posts 21 are provided on both sides of the house, respectively.
Are mounted, and both ends of the take-up shaft 16 of the film for house 15 are connected to the lifting units 22 respectively.

According to such a configuration, the winding shaft 16 is prevented from tilting when the film 15 for a house is wound. In particular, the inclination of the winding shaft 16 when the house is long can be reliably prevented.

According to the apparatus of the present embodiment, the following operation and effect can be obtained.

A. Since the small DC motor 23 is used in the lifting unit 22, not only the weight of the lifting unit 22 can be reduced, but also the house film 15 can be opened and closed using the battery 41 and the solar cell 42 even in a place where there is no AC power supply. It becomes possible. Therefore, the house film 15 can be automatically wound up even if the installation place of the cultivation house is far from the house of the manager and the wiring of the commercial power supply is not performed.

B. Since the elevating unit 22 moves up and down by using the guide columns 21 having substantially the same shape as the arched frame 10 on which the fixed film 11 is extended, the curving frame can be opened and closed even with a curved frame.

C. Rolling wheel 3 that fits on guide post 21
0 is sandwiched between two upper and lower portions in the elevating unit 22, and the light weight driving motor 23 is used. Therefore, the guide column 21 loses the weight at hand and becomes bowed or slipped. It can be opened and closed without falling.

D. Since the sleeve type joint 26 connecting the output shaft 25 of the speed reducer 24 connected to the drive motor 23 and the take-up shaft 16 can move in the axial direction, the guide column 21 is pulled out at the time of attachment / detachment or rework. There is no need to move or move, and the mounting labor can be reduced and the mounting accuracy can be improved.

E. Since the spring stopper 35 is used, even if the lifting unit 22 hits the stopper 35, the stopper 35 absorbs the load by the cushion. Therefore, the stopper 35, the lifting unit 22 and / or the non-contact proximity switch 47 are not used. No damage.

In addition, since the stopper 35 having a bent structure formed by bending a stainless steel plate is used, the position where the sensing surface is set is maintained. Furthermore, since the load is absorbed by the cushion with the spring function, an unnecessarily strong attachment for the attachment to the guide post 21 is not required, and the fitting type which can be easily attached and detached may be used. The mounting position can be easily changed according to conditions such as weather.

F. Since the stopper 35 is detected by using the non-contact proximity switch 47, the contact load on the lifting unit 22 and the stopper 35 is eliminated, and a double contact load measure is taken by using the cushion stopper 35. Become. Also, countermeasures against switch failure due to contact destruction are taken.

G. Since the film holding string 17 can be tightened and loosened by a necessary length by the winding shaft driving motor 53 shown in FIG. 6, it is possible to open and close the film pressing string to a desired position without applying an unnecessary load for opening and closing.
