[0002]

2. Description of the Related Art In recent years, forcing cultivation of vegetables and fruits has been carried out, and a vinyl greenhouse is generally used for this forcing cultivation. This vinyl house is constructed by forming a skeleton-like frame made of iron or wood in advance, and covering it with a winding sheet made of a vinyl sheet. And in greenhouses that perform forced cultivation, the temperature of the inside air is made higher than the temperature by shutting off the inside from cold outside air, but the temperature inside the greenhouse rises too much during the daytime except in winter. , I open the area around the vinyl house to let in the outside air.

[0003]

However, since the above-mentioned work is carried out by the manager of the vinyl house while measuring the temperature in the vinyl house, it is a heavy labor that requires nerves, and if it is opened too much, it should be closed properly. However, there is a problem that it is extremely difficult to control the temperature. Therefore, in order to solve the above-mentioned problems, the applicant of the present application has previously disclosed, in Japanese Patent Application No. 6-204296, the automatic winding sheet opening / closing device for a vinyl greenhouse having a winding sheet having a winding rod at the lower end on its side surface.

And a control device for controlling the temperature in the vinyl house within a certain range by operating the rotary drive source as an input.

With the above structure, the winding sheet automatic opening / closing device of the vinyl house can smoothly open and close the winding sheet by using power. In addition, the temperature inside the greenhouse can be measured by the temperature sensor, and the opening and closing of the rolled-up sheet can be controlled so that the temperature inside the greenhouse is always within a certain range. . Further, since the power of the rotary drive source is transmitted to the winding rod through the flexible shaft, the installation position of the rotary drive source can be freely determined.

However, the above-described automatic winding sheet opening / closing device for a vinyl house still has the following problems to be solved. That is, in the winding operation of the rolled-up sheet, the flexible shaft is required to be long in proportion to the opening / closing stroke of the rolled-up sheet, and when the building height of the vinyl house is high, the rolled-up sheet cannot secure a sufficient opening / closing stroke, and is flexible. The installation space including the shaft and the rotary drive source connected to the other end of the flexible shaft becomes large. Furthermore, when it is necessary to open and close the winding sheet of the vinyl house in two steps, the flexible shaft is congested and the smooth opening and closing function is impaired.

The present invention has been made in view of the above circumstances, and the temperature control work of a vinyl house can be easily performed, the apparatus itself can be manufactured at low cost, and the installation space can be minimized. It is an object of the present invention to provide an automatic winding sheet opening / closing device.

After a predetermined time has elapsed, the indoor temperature sensor 17 reads the indoor temperature F ° C inside the vinyl house B into the control device 18 (step 211). If the indoor temperature F ° C is lower than the lower limit set temperature b ° C, the lower temperature The rotation drive source 16 is operated to reverse the rotation, and the lower winding rod 11 is rotated reverse to lower the lower winding sheet 10 (step 212). This lowering operation reduces the amount of outside air flowing into the greenhouse B from the lower part.

After a lapse of a predetermined time, the indoor temperature sensor 17 controls the indoor temperature F.degree.
8 (step 213), if the indoor temperature F ° C is not lower than the lower limit set temperature b ° C, that is, the lower limit set temperature b
If the temperature is higher than or equal to ℃, the lower rotary drive source 1
The operation of 6 is stopped to stop the lowering operation of the lower winding sheet 10 (step 215). After a predetermined time has elapsed, the indoor temperature sensor 17 reads the indoor temperature F ° C inside the greenhouse B into the control device 18 (step 21).
3) Even if the indoor temperature F ° C is lower than the lower limit set temperature b ° C, if the lower limit switch 31 of the lower stage is activated by the lowering of the winding rod 11 of the lower stage (step 21)
4) The operation of the lower rotary drive source 16 is urgently stopped to stop the lowering operation of the lower winding sheet 10 (step 215). Then, after a lapse of a predetermined time, the indoor temperature sensor 17 reads the indoor temperature F ° C. inside the greenhouse B into the control device 18 (step 216). If the indoor temperature F ° C. is still lower than the lower limit set temperature b ° C. The rotary drive source 16 is operated to reverse the rotation, and the upper winding rod 11 is rotated reverse to lower the upper winding sheet 10 (step 21).
7). By this unwinding operation, not only the lower portion into the greenhouse B but also the inflow amount of outside air from above is reduced.

After a lapse of a predetermined time, the indoor temperature sensor 17 controls the indoor temperature F.degree.
8 (step 218), if the indoor temperature F ° C. is not lower than the lower limit set temperature b ° C., that is, the lower limit set temperature b
If the temperature is higher than or equal to ℃, the upper rotary drive source 1
The operation of 6 is stopped to stop the lowering operation of the upper winding sheet 10 (step 220). After a predetermined time has elapsed, the indoor temperature sensor 17 reads the indoor temperature F ° C inside the greenhouse B into the control device 18 (step 21).
8) Even if the indoor temperature F ° C. is lower than the lower limit set temperature b ° C., if the lower limit switch 31 of the upper stage is activated by lowering the winding rod 11 of the upper stage (step 21)
In step 9), the operation of the upper rotary drive source 16 is urgently stopped to stop the lowering operation of the rolled-up sheet 10 (step 220). Thereafter, the process returns to step 201.

If it is determined in step 206 that the indoor temperature F ° C. is not higher than the upper limit set temperature a ° C., that is, if it is lower than or equal to the upper limit set temperature a ° C., step 2
21, the indoor temperature F ° C. in step 221
Is lower than the lower limit set temperature b ° C., the process proceeds to step 217, and the upper rotary drive source 16 is operated to reverse the rotation.
Reverse the upper winding rod 11 and lower the lowering sheet 10
