  According to a fourth aspect of the present invention, in the ventilator for barns according to the second to third aspects, the control device includes a barn temperature input means, and the temperature in the barn detected by the barn temperature detecting means is below a set temperature. When descending, the ventilator stop means stops driving the ventilator, and the shutter “close” command means is actuated by a command signal from the ventilator stop means, and the shutter opening / closing motor is connected to the shutter closing detection means. The shutter is closed by driving until it is confirmed that the shutter of the ventilator is closed.

  According to a fifth aspect of the present invention, in the barn ventilator according to the second to fourth aspects, the control device includes a barn temperature input means and a ventilation amount increase / decrease means of the blower, and the temperature in the barn is higher than a set temperature. When descending, the ventilator drive is stopped by operating the ventilator stop means by the command signal from the barn temperature input means, and the shutter “close” command is issued by the command signal from the ventilator stop means And the shutter opening / closing motor is driven until the shutter closing is confirmed by the shutter closing detecting means to close the shutter of the ventilator, and the air flow rate increasing / decreasing means by the command signal from the barn temperature input means Is configured to reduce the amount of air blown by the blower disposed in the barn according to the temperature drop.

  According to a sixth aspect of the present invention, in the ventilator for barns according to any one of the fourth to fifth aspects, the control device includes a barn temperature input unit and an air flow rate increase / decrease unit of the blower, and the temperature in the barn has a set temperature. When it exceeded, it was comprised so that the ventilation volume of the air blower arrange | positioned in the barn could be increased according to the temperature rise with the command signal from a barn temperature input means.

  According to a seventh aspect of the present invention, in the ventilator for barns according to the third to sixth aspects, the control device includes a barn temperature input unit and an air flow rate increase / decrease unit of the blower, and the temperature in the barn is higher than a set temperature. When the set temperature is reached from the lower state or when the set temperature is exceeded, the shutter "open" command means is actuated by a command signal from the barn temperature input means, and the shutter open / close motor is moved to the shutter open detection means. After opening the shutter of the ventilator by confirming that the shutter is open, the ventilator driving means outputs a drive command to the ventilator to drive the ventilator, and the air volume of the air blower is set in the barn It is characterized by being configured to increase in response to a temperature rise.

  The invention according to claim 8 is the ventilator for barns according to claims 3 to 7, wherein the control device stops the air blower with the air blower stop means and then receives a command signal from the air blower stop means. The ventilator stop means is operated to stop the ventilator, and the shutter “close” command means is operated by a command signal from the ventilator stop means, and the shutter open / close motor is connected to the ventilator by the shutter close detection means. The shutter is closed by driving until the shutter is confirmed to be closed.

  In the invention according to claim 1, a plurality of blower devices suspended so as to have a predetermined interval in the longitudinal direction in the barn and generating an air flow in the barn, and the longitudinal direction in the barn A predetermined number of ventilators attached to the wives of the barn located on both ends of the direction, and exhausting the airflow in the barn generated by the blower to the outside; and before the ventilator is driven to the ventilator and Since it has a shutter that automatically opens and closes after the stop, the ventilator for the barn is constructed, so that the barn is always uniform in any part of the barn due to the airflow generated by the driving by a plurality of blowers. Because the generated air flow can be supplied, the inside of the barn can be maintained in a well-dried (ventilated) state, and by driving the ventilation device attached to the end face of the longitudinal direction of the barn, Raised in the barn Because of the presence of the air blower and the ventilator, the inside of the barn always discharges the air (airflow) containing the humidity and the odor of the livestock out of the barn, Since fresh and clean outside air can be taken into the barn from outside the barn, it is possible to promote ventilation with a fresh airflow at all times in the barn, so that the livestock breeding environment can be improved satisfactorily. It was possible to raise livestock hygienically and with peace of mind.

  According to the second aspect of the present invention, when the shutter opening / closing electric motor confirms that the shutter is completely opened by driving the shutter opening / closing motor attached to the ventilation device, the ventilation device is driven. To stop the ventilation device after confirming that the shutter closing detection means is not in operation, and then driving the shutter opening / closing motor to close the shutter, and to close the shutter Since the shutter opening / closing motor is stopped by checking with the shutter closing detection means, the opening / closing of the shutter provided in the ventilation device is always confirmed before the ventilation device is driven by the shutter opening / closing detection means, or confirmation of the drive stoppage. So that the shutter can be opened while the ventilator is in operation. It is possible to reliably prevent, thereby, a problem that the shutter is damaged by wind pressure ventilator can be prevented, moreover, it is possible to reliably perform drive and stop of the ventilation system, it is convenient.

  In the third aspect of the invention, the control device is configured to drive the ventilation device after driving the blower and confirming the opening of the shutter, and close the shutter after stopping the driving of the ventilation device when the shutter is closed. Therefore, the blower that generates airflow in the barn and the ventilation device that discharges the airflow in the barn and flows fresh outside air into the barn are driven almost simultaneously with the opening of the shutter. Therefore, the airflow in the barn can be smoothly performed without damaging the shutter. In addition, when the air flow inside and outside the barn is not distributed, the shutter is automatically closed after the ventilator is stopped, so that the shutter can be reliably damaged by closing the shutter while the ventilator is in operation. In addition, the airflow generated by driving only the blower in the barn can be circulated in the barn, so if there is a large temperature difference at night or inside or outside the barn, the airflow is only inside the barn. Since it is possible to maintain a substantially uniform temperature in any part of the barn by circulating the, the livestock breeding environment can be maintained well.

  In the invention of claim 4, when the temperature in the barn falls below a predetermined set temperature, the drive of the ventilation device is temporarily stopped and the drive of the blower device is continued with the shutter closed. Since the control device is configured to circulate only the airflow in the barn, it is possible to reliably prevent the inflow of outside air lower than the temperature in the barn and to suppress the temperature drop in the barn well. It is possible to maintain the breeding environment without deteriorating the breeding environment, and it is convenient that the livestock can be raised in a favorable environment, and the ventilation environment is not used, so the breeding environment in the barn is energy saving operation It also has the advantage that it can be maintained.

  In the invention according to claim 5, when the temperature in the barn falls below a predetermined set temperature, the shutter is closed simultaneously with the stop of the ventilation device, and the air flow rate of the blower is set to the temperature drop in the barn. Since the control device is configured so that it can be reduced according to the temperature, even if the temperature in the barn drops below the set temperature, the amount of air blown by the blower affects the breeding of livestock even if the temperature falls below the set temperature. Can be controlled so that the temperature in the vicinity of the ventilator installation area can be well prevented by stopping the ventilation system and continuing the ventilation by the blower (reduction of the air flow). It is possible to generate and circulate airflow at almost uniform temperature in any part of the barn, and livestock can be bred well with less influence of outside air temperature, which is convenient.

  In the invention described in claim 6, when the temperature in the barn exceeds a predetermined set temperature, the control unit is configured to increase the amount of air blown from the blower in accordance with the temperature rise. As the air volume increases, the increased amount of airflow can be expelled out of the barn early (ventilation device) to promote good circulation with the outside air, which actively exchanges the airflow inside the barn and the outside air. Since the temperature rise in the barn can be effectively suppressed, there is an advantage that the deterioration of the breeding environment accompanying the temperature rise in the barn can be satisfactorily suppressed.

  In the invention of claim 7, when the temperature in the barn reaches a set temperature as the outside air temperature rises from a state below a predetermined set temperature, or when the temperature rises above the set temperature, As the control device is configured to suppress the temperature inside the barn from rising beyond the set temperature by opening the shutter and driving the ventilator while increasing the air flow rate in response to the temperature rise For example, even if the outside temperature is lower than the set temperature in the morning, if the outside temperature gradually rises over time and the temperature inside the barn reaches or exceeds the set temperature, Immediately after the shutter of the ventilator is automatically opened and the ventilator is driven, the blast volume of the blower can be increased automatically in response to the temperature rise. This is convenient because it can be raised while suppressing the problem of adversely affecting livestock due to sudden changes in the breeding environment. .

  In the invention described in claim 8, when stopping the blower in the barn, the blower is first stopped, and then the ventilator is stopped based on the command signal indicating that the blower is stopped. Since the control device is configured to receive a command signal indicating that the device has stopped and drive the shutter opening and closing motor to close the shutter, the shutter installed in the ventilation device is used to drive the blower and ventilation device. Therefore, the shutter can be smoothly closed without being subjected to the wind pressure generated by the above, and thus damage to the shutter when the ventilator is stopped can be favorably avoided. In addition, since the generation of airflow in the barn and the flow of the airflow were stopped and the shutter was closed, the blower and ventilator were in operation until just before the shutter was closed. There is also an advantage that it is possible to effectively avoid the deterioration of the breeding environment due to the outside air flowing into the barn more than necessary.

The connecting plate 16 is pushed down, the shutter 5 attached to the shutter flange 14 pivotally attached to the connecting plate 16 is rotated clockwise with the support pin 15 as a fulcrum, and the space 4b surrounded by the shutter frame 9a The inside of the window 4 opened on the wife surface 1a in the barn 1 is gradually opened. That is, the space 4b portion of the shutter device 9 is automatically opened.

The shutter 5 is gradually opened by driving the shutter opening / closing motor 6b, and the shutter 5 is opened to a predetermined level (when the shutter 5 reaches a substantially horizontal position as shown in FIG. 7, that is, when the shutter 5 is opened). When the position is reached, as shown in FIG. 7, the proximal link 17 pushes (opens) the shutter opening detection means (limit switch) 22 to open the energization circuit of the shutter opening / closing motor 6b shown in FIG. blocking), and stops the driving of the shutter opening and closing motor 6b (see S ₄ in FIG. 6b, 22 and 4 5).

When the shutter opening detection means 22 is opened (shut down), the “open” signal is sent to the shutter “open” command means 33, and the shut-off command signal is output from the shutter “open” command means 33 to the operation switch 24. The operation switch 24 is opened (shut off). With the opening of the operation switch 24, the shutter closing detection means (limit switch) 21 shifts from the open state to the closed state. On the other hand, the shutter opening detection means 22 outputs a drive command signal to the ventilator drive means 34 at the same time as the opening command of the operation switch 24 to operate the ventilator drive means 34, and outputs a closing command signal to the ventilator operation switch 23. and drives the ventilator 3 by activating the motor 6a (see S _4, S ₅ in FIG. 5).

The air flow generated in the barn 1 by the driving of the blower 2 is sequentially diffused in the barn 1 by the drive of the ventilator 3, and is circulated in the length direction of the barn 1 by the ventilator 3. However, it is discharged out of the barn 1 through the window 4 of the shutter device 9. By exhausting the airflow in the barn 1 to the outside by the ventilator 3, the introduction of fresh outside air is promoted from the outside of the barn 1 on the contrary, and the inside of the barn 1 is cleaned by generating airflow and introducing the outside air. Ventilate. By this ventilation, the odor and moist atmosphere in the barn 1 are discharged to the outside, and the barn 1 is kept clean and dry (see 3 in FIG. 4 and S ₅ and S _{6 in} FIG. 5).

While the inside of the barn 1 is ventilated by driving the blower 2 and the ventilator 3, the temperature in the barn 1 is always measured by the barn temperature detecting means (temperature sensor) 25, and the measured detected temperature is the control device. The data are sequentially input to ten barn temperature input means 35. That is, assuming that the temperature in the barn 1 is different from the preset temperature before driving the blower 2 by promoting the rise of the outside air temperature or the introduction of the outside air, for example, When ventilation is performed with the temperature set at 20 ° C., the temperature in the barn 1 detected by the barn temperature detecting unit 25 is sequentially input to the barn temperature input unit 35 provided in the control device 10 as described above. (Refer to S ₇ and S _{8 in} FIG. 5).

If the detected temperature input to the barn temperature input means 35 is not different from the set temperature input from the set temperature input means 31, that is, if the detected temperature is 20 ° C. set in advance, the blower 2 is set. The blower fan 7 is controlled to be driven at the same rotational speed as before by the rotational speed signal set based on the temperature. That is, the air blower 2 is driven and controlled at a constant speed operation (see _{S81 in} FIG. 5).

However, when the temperature inside the barn 1 detected by the barn temperature detection unit 25 input to the barn temperature input unit 35 is higher than the set temperature, for example, 21 ° C., the blower fan 7 corresponding to the temperature of 21 ° C. The rotation speed increase / decrease command signal is output from the barn temperature input means 35 to the air flow increase / decrease means 36. The blower amount increase / decrease means 36 outputs a rotation speed increase / decrease command signal of the blower fan 7 corresponding to the temperature of 21 ° C. set in advance to the operation control unit 12 of the blower 2, and the blower fan of the blower 2. 7 is rotated at a speed up to a rotational speed corresponding to a temperature of 21 ° C. That is, the blower 2 is rotated at a high speed, restrain the increasing occurrence of air flow into the barn 1 temperature in barn 1 is increased (see S ₉ of FIG. 5).

On the other hand, when the temperature inside the barn 1 becomes lower than the set temperature due to a change in the outside air temperature, that is, when the temperature inside the barn 1 detected by the barn temperature detecting means 25 is lower than the set temperature (20 ° C.). For example, if the detected temperature is 19 ° C. and the detected temperature is input to the barn temperature input means 35, the air flow corresponding to the temperature of 19 ° C. is sent from the barn temperature input means 35 to the air flow rate increase / decrease means 36. The rotational speed increase / decrease command signal of the fan 7 is input, and thereby the air flow increase / decrease means 36 outputs the rotational speed increase / decrease command signal decelerated to the rotational speed corresponding to the temperature of 19 ° C. to the operation control unit 12 of the blower 2. rotating the blower fan 7 Te, to reduce the blowing amount of air flow that occur in the barn 1 (see S ₁₀ of FIG. 25 and FIG. 5).

Further, as described above, when the barn temperature detecting means 25 detects a temperature (19 ° C.) in which the temperature inside the barn 1 is lower than the set temperature (20 ° C.), the detected temperature is input to the barn temperature input means 35. Then, the barn temperature input means 35 outputs a command signal to the ventilator stop means 37 to operate the ventilator stop means 37, and sends a ventilator stop command signal from the ventilator stop means 37 to the ventilator drive means 34. At the same time, a shutter closing command signal for closing the shutter 5 is output to the shutter “closing” command means 38. When the ventilator drive means 34 receives the ventilator stop command signal, it outputs a shut-off command to the ventilator operation switch 23 and shuts off the ventilator operation switch 23 to stop the drive of the ventilator 3 (FIG. 4). Referring S ₁₀ in 3 and 5).

  On the other hand, when a shutter close command signal is output to the shutter “close” command means 38, the shutter “close” command means 38 outputs a closing command signal to the operation switch 24 a of the shutter opening / closing motor 6 b and turns the operation switch 24 a on. throw into. When the operation switch 24a is turned on, the shutter closing detection means 21 is already turned on, so that the energization circuit of the shutter opening / closing motor 6b is closed and the shutter opening / closing motor 6b is immediately in the opposite direction to that when the shutter 5 is opened. To drive. That is, in FIG. 7, the shutter 5 is rotated in a direction suitable for moving in the counterclockwise direction (closing direction).

  As a result, the proximal link 17 is rotated counterclockwise in FIG. 7 and the driven link 18 is pushed upward in FIG. When the driven link 18 is pushed up, the connecting plate 16 connected to the driven link 18 via the connecting piece 19 is pushed upward, and the shutter 5 pivotally attached to the connecting plate 16 is attached to the support pin 15. Is turned counterclockwise with the fulcrum as a fulcrum to gradually close the space 4b in the shutter frame 9a. That is, the shutter device 9 is closed.

The shutter 5 is automatically closed gradually by the driving of the shutter opening / closing motor 6b, and the shutter 5 itself closes the space 4b portion in the window 4 (position where the shutter 5 is substantially vertical as shown in FIG. 6). ), The driven link 18 pushes (opens) the shutter closing detection means (limit switch) 21 and opens (cuts off) the energization circuit of the shutter opening / closing motor 6b as shown in FIG. It stops the driving of the electric motor 6b (see S ₁₀ of 6b, 21 and 5 in Fig. 4).

Along with the opening of the shutter closing detection means 21, the “closed” signal is output to the shutter “closing” command means 38. In response to the input of the “close” signal, the shutter “close” command means 38 outputs a shut-off command signal to the operation switch 24a to shut off (open) the switch 24a. The interruption of the operation switch 24a, the shutter opening detection means 22 (limit switch) transitions from the open state to the closed state (see S ₁₀ of 6b, 21 and 5 in Fig. 4).

As described above, in step S ₈ of FIG. 5, if the detected temperature in the barn 1 detected by barns temperature detecting means 25 has fallen below the set temperature set in advance, the process proceeds to step S ₁₀ in FIG. 5 The operation of the ventilation device 3 is stopped, the shutter device 9 is closed, and in this state, the blower fan 7 is decelerated and rotated corresponding to the detected temperature, thereby reducing the amount of airflow generated in the barn 1. . Thus, by avoiding sickness (disease, discomfort, stress) caused by not changing the airflow rate of the livestock in the barn 1 when the temperature drops, the barn 1 is maintained by continuing the slowed air blowing state. The dry state of the inside is promoted well, and livestock can be raised hygienically.

Further, in step S ₈ of FIG. 5, if the detected temperature in the barn 1 is the same as the set temperature set in advance, to drive at a constant speed driving the blower 2 and proceeds to step S ₈₁ in FIG. 5 It is configured as follows.

  As described above, in the present invention, when the blower 2 is driven, the temperature in the barn 1 grasped in advance is input to the control device 10 as the set temperature, and the blower in the blower 2 is sent according to this set temperature. When the number of rotations of the fan 7 is selected (for example, when the temperature in the barn 1 is set to 20 ° C., the number of rotations of the blower fan 7 at 20 ° C. is set in advance, so that The control command signal corresponding to the rotation speed signal is output to the electric motor 6. As a result, the blower fan 7 is rotated by the electric motor 6 at a rotation speed corresponding to the set temperature to generate an airflow in the barn 1, and the airflow in the barn 1 and the outside air outside the barn 1 are driven by the ventilation device 3. To keep the air in the barn 1 clean.

  On the other hand, the temperature in the barn 1 is always detected by the post-driving barn temperature detecting means 25 of the blower 2, and when the detected temperature is higher than a preset temperature, the rotation speed of the blower fan 7 corresponding to the detected temperature is set. By rotating at a high speed, the temperature in the barn 1 suddenly rises and adversely affects livestock breeding, and the temperature in the barn 1 falls below the set temperature due to the intrusion of outside air temperature. In this case, the rotational speed of the blower fan 7 is decelerated and rotated at a rotational speed corresponding to the lowered temperature, and the ventilator 3 stops driving to prevent a temperature drop due to the inflow of outside air, and the shutter 5 is automatically closed. . As a result, it is possible to reliably prevent the outside air from forcibly flowing into the barn 1 and to satisfactorily suppress the problem that the temperature further decreases in the barn 1 due to the inflow of outside air.

Then, to detect the temperature constantly barn 1 by barn temperature detecting means 25, if the detected temperature rises above the set temperature, the process returns to the step S ₉ of FIG. 5, and continues the high-speed rotation of the blower 2 . Further, the detected temperature is if I followed by a state below the set temperature, continuing the low speed operation of the blower 2 returns to step S ₁₀ in FIG. Furthermore, if the detected temperature in the barn 1 is the same as the set temperature, that is, if it has not changed, the blower 2 continues the constant speed operation (see S ₁₁ and S _{12 in} FIG. 5).

Then, the case of constant speed operation in step S ₁₂ in FIG. 5 a blower 2, when the detected temperature in the barn 1 were driven blower 2 (Step S ₃₎ of the set temperature special problem if the same as the no but or if you do not want the detected temperature in the barn 1 during constant speed operation of the blower 2 is below the set temperature, or, conversely, if it exceeds the set temperature, steps S from step S ₁₃ of FIG. 5 moves to _11, or to high-speed operation of the blower 2 in step S ₉ of FIG. 5, decelerating operation proceeds to step S _11, S ₁₀ from the step S ₁₃ in FIG. 5 (see S ₁₃ in FIG. 5) .

The drive of the ventilation device 3, but omitted the detailed description will described in detail in step S ₄ in FIG. 5, when the detected temperature in the barn 1 is raised to a set temperature, the blower driven from barn temperature input means 35 A command signal for causing the air blower 2 to operate at a constant speed (the number of rotations of the air blowing fan 7 corresponding to the set temperature) is output to the means 32 to operate the air blower 2 at a constant speed and the shutter from the air blower driving means 32 is operated. When the shutter open command signal is output to the “open” command means 33 and the shutter opening / closing motor 6 b is driven to open the shutter 5, the drive command signal is sent from the shutter “open” command means 33 through the ventilator drive means 34 to the ventilator. 3 and the ventilator 3 is driven again.

In the barn 1, when stopping the driving of the blower 2 stops by the blower drive switch (not shown) provided in the control device 10 opens (blocking) (see step S ₁₄ in FIG. 5) (Fig. 5 see S _15). When the operation of the blower 2 is stopped, the ventilator stop command signal is output from the blower stop means 39 of the control device 10 to the ventilator drive means 34 via the ventilator stop means 37, and the ventilator 3 stops the operation. To do. Thereafter, although it would be closing the shutter device 9, in this case, although detailed description will be same operation as described in detail in step S ₁₀ of FIG 5 will be omitted, after the stop of the operation of the ventilator 3 drives the shutter opening and closing motor 6b, it is to automatically close the shutter 5 (see S _14, S ₁₅ in FIG. 5).

Further, the detected temperature in the barn 1 is higher than the set temperature conditions or, when stopping the blower 2 in a low state, by performing the same operation as step S ₁₄ in FIG. 5, not shown, of the control device 10 blower stops the blower 2 by opening the drive switch, hereinafter, stopping the ventilator 3, the closing of the shutter device 9, description will be the same as the contents described in step S ₁₀ in FIG. 5 omitted (see S ₁₅ in FIG. 5).

Note that, in step S ₁₁ in FIG. 5, from a state in which barn 1 in the temperature is below the set temperature, when a state exceeding the set temperature, the process proceeds to step S ₄ in FIG. 5, the shutter unit 9 To open the shutter 5 and drive the blower 2 and the ventilator 3.
