TECHNICAL FIELD OF THE INVENTION
The present invention relates to a reversible spray blower system comprising a plurality of reversible spray blowers for adjusting the temperature and humidity of a room by blowing air or spraying water mainly in a piggery or other livestock breeding houses or plant cultivation houses.
[0002]
[Prior art]
Conventionally, measures such as mounting a fan or a sprayer on the ceiling of the barn have been taken in order to suppress a rise in the temperature of the barn and other livestock breeding livestock and maintain and regulate a proper temperature. For example, an apparatus has been disclosed in which water is blown downward by a fan through water through an erofin pipe, and water is sprayed downward from a nozzle to lower the indoor temperature (see Patent Document 1). However, this is only spraying downward or in a fixed horizontal direction, and has the effect of locally lowering the temperature, but has little effect of lowering the temperature of the entire room by spreading the spray in all directions. Then, the inventor of the present application invented "a reversible mount and a spray blower using the mount" and filed an application earlier (see Patent Document 2).
[0003]
According to the invention described in Patent Document 2 previously filed by the inventor of the present application, the spray blower rotates forward and backward by 360 degrees, so that, for example, livestock bred in a partition is sprayed or blown alternately from both directions. As a result, the problem of breeding unevenness caused by air blowing from only one direction in the past has been completely solved. The same applies to the cultivation of plants in a plant cultivation house, and the breeding environment and cultivation environment optimal for livestock and plants can be provided by the reversible spray blower that rotates 360 degrees forward and backward.

[Problems to be solved by the invention]
However, the above-mentioned spray blower applied by the inventor of the present application does not cause any problem when used alone, but when using a plurality of these, each reversible spray blower is used. In the case of one-to-one reversal control, it is necessary to control the number of reversing spray blowers, which not only increases the cost, but also causes each spray blower to reverse independently. As a result of repeating the operation, the directions of the spray blasts vary, and it becomes difficult to adjust the greenhouse degree without unevenness in the room because the spray blasts blown out from both the spray blowers collide with each other or some places cannot reach. In addition, when the motor is operated for a long time due to a slight error in the number of rotations for each motor used and the angle of rotation by inertia when the motor reverses, there is a difference between the motors. As a result of rotation in one of the opposite directions, there is a problem in that the rotation difference is added and the spray blowing direction is varied, and finally, the electric wiring cord is entangled. Therefore, an object of the present invention is to solve the above-described problems by controlling a plurality of reversing spray blowers by a single control device in a forward / reverse reversal manner, and spraying a spray to each spray blower. It is an object of the present invention to provide an economical reversible spray air blowing system that can efficiently and efficiently control a greenhouse degree by providing a correcting means for correcting a blowing direction or an angle deviation.

FIG. 7 is a wiring diagram illustrating the connection between the master unit and the slave unit.
[0017]
In the control panel 2 of FIG. 2, WL is a power indicator lamp, which is turned on when the system is turned on. COS is a changeover switch, COS1 is used to select automatic operation or manual operation of the system, and COS2 is a changeover switch for the rotation direction of the motor, and can be selected from forward rotation, reverse rotation or neutral. it can. When automatic operation is selected in COS1, the reversing motor 15 automatically repeats forward / reverse inversion according to the setting, and when manual operation is selected, the motor rotates in the direction selected by the changeover switch of COS2, or stand by.

Next, a sequence diagram of the master unit in FIG. 4 will be described. 4, COS1, COS2, and COS3 correspond to the respective changeover switches of the control panel 2 of FIG. First, the forward / reverse inversion circuit of the inversion motor will be described. When the changeover switch COS1 is set to manual, when the COS2 is turned forward, the 52F relay is turned on and the 52F switch is turned on and the reversing motor is turned forward. When the COS2 is turned reversely, the 52R relay is turned on and the 52R switch is turned on and the reversing is performed. The motor rotates in reverse. In this case, since the 52F relay and the 52R relay form an interlock circuit, when one of the relays is turned on, the other relay is in a non-conducting relationship, thereby avoiding simultaneous turning on / off of the forward / reverse switch.

Since the reversing motor has substantially the same number of forward and reverse rotations, the reverse rotation limit switch 17 contacts the contact portion 18 with the rotation of the horizontal bevel gear 14a three minutes after the reverse rotation starts. Expires. Then, the LX relay for stopping reverse rotation is turned off, the LX switch is turned off, and the 52R relay is turned off to stop reverse rotation. At about the same time, one minute after the start of the normal rotation restart timer TM1, the switch BX is connected and the 52F relay is turned on to start normal rotation. This series of operations is sequentially repeated. As described above, the inverted substrate makes one full rotation in the normal rotation in three minutes, and then makes one full rotation in the reverse rotation in the next three minutes. A waiting time of one minute is provided between the normal rotation and the reverse rotation. The time required for the reversing substrate to make one rotation can be adjusted by changing the rotation ratio of the bevel gear linked to the motor. The connection of the three-phase induction motor in the forward / reverse direction is described in FIGS.
[0022]
Further, the reversing type spray blowing system of the present embodiment is provided with a 24-hour timer TM24, and can perform automatic operation within a maximum of 24 hours. The relay 521 that is linked with the switch 521 of the blower is linked with the 52F relay and the 52R relay, and the blower operates in synchronization with the rotation of the reversing motor in either forward or reverse rotation. When the 52F relay is turned on by switching the drain pump to the normal rotation by the changeover switch COS3, the 522 relay is turned on and the drain pump operates. By switching COS3 between forward and reverse rotation, the drain pump operates in synchronization with one of the forward and reverse rotations in conjunction with the 521 relay.

After that, power is supplied to the reversing motor of the slave unit. The UVW1 of the slave unit is a terminal connected to the UVW1 in the main power supply wiring diagram via the circuit breaker MCB, and supplies power to the blower of the slave unit via the UVW11 terminal at the same timing as the blower of the master unit. . UW3 is a terminal connected to UW3 in the main power supply wiring diagram, and supplies power to the drain pump of the slave unit via the UW13 terminal at the same timing as the drain pump of the master unit. It is connected to the upper base line of the slave unit sequence diagram of FIG. 6 via the fuse at the right end of the wiring diagram. FIG. 7 is a wiring diagram illustrating the connection of two slave units C1 and C2 to the master unit P1, but three or more slave units (C3 to C3) can be similarly connected.
[0024]
In the slave device sequence diagram of FIG. 6, the X-1 switch operates in conjunction with the X-1 relay of the master device sequence diagram of FIG. 4, and the 52R switch is connected to the F and G terminals of the master device sequence diagram of FIG.

Will be done.
[0025]
FIG. 8 is an explanatory diagram showing the relationship between the contact portion 18 on the horizontal bevel gear 14a and the forward / reverse Mitt switch (16, 17). The operation for correcting the deviation of the direction or angle between the forward rotation limit switch, the reverse rotation limit switch, and the spray blower will be described in detail with reference to FIG. In this embodiment, the forward rotation (forward rotation) of the spray blower or the horizontal bevel gear 14a refers to counterclockwise rotation, and the reverse rotation (reverse rotation) refers to clockwise rotation. When the reversing type spray blowing system is automatically operated for the first time, the rotation starts from normal rotation, and the position where the contact portion of the horizontal bevel gear 14a contacts the reverse rotation limit switch 17 is defined as the origin.
[0026]
In FIG. 8, when (a) is the master unit and (b) and (c) are slave units, the master unit (a) has the contact unit 18 stopped at the position of the origin, and the slave unit ( The contact portions 18 in (b) and (c) are stopped at positions away from the origin. When the automatic operation switch is turned on in this state, both the parent device and the child device start normal rotation, and the contact portion 18 is turned forward in the order of the child device (c) located farthest from the origin and then (b). It comes into contact with the rotation limit switch and stops and waits. Finally, the contact portion 18 of the master unit (a) comes into contact with the forward rotation limit switch, or after 3 minutes from the start of forward rotation, the forward rotation timer TMA relay is turned off, the 52F relay becomes non-conductive, and forward rotation stops. One minute after the parent machine (a) stops, (a), (b) and (c) simultaneously start reverse rotation. As described above, the deviation of the direction or angle between the spray blowers can be corrected.
[0027]
Next, in FIG. 8, when (c) is the master unit and (a) and (b) are slave units, the master unit (c) contacts the forward rotation limit switch 16 first. And the slave units (a) and (b) are stopped at the same time. At this time, the slave units (a) and (b) are stopped at the intermediate position between both limit switches, and one minute after the master unit (c) stops, all units start reverse rotation from their respective positions. . Eventually, the contact portions 18 come into contact with the reverse rotation limit switch 17 in the order of the slave units (a) and (b) and finally the master unit (c), and all the units stop at the home position. One minute after the parent machine (c) stops, all the machines start normal rotation from the home position, so that the direction or angle deviation between the spray blowers can be corrected. The correction of the direction or the angle deviation described above is performed not only at the time of the above-described start, but also in the case of the continuous operation, the correction of the rotational direction or the angle deviation generated in one of the forward and reverse directions. The same applies to the case where three or more slave units are connected.
[0028]
FIG. 9 shows a position where the contact portion 18 on the upper surface of the horizontal bevel gear 14a is in contact with each limit switch and 180 degrees apart from each other in the case of a spray blower that rotates forward and backward within a range of 180 degrees. An example is shown in which two (18a, 18b) are provided. When the parent device is a 360-degree forward / reverse rotation spray fan and the slave device is the 180-degree forward / reverse rotation spray fan, first, the contact portion 18a of the slave device is at the position of the origin, and normal rotation starts, When the horizontal bevel gear 14a rotates approximately half a turn, the contact portion 18b comes into contact with the forward rotation limit switch 16 and stops, and in this state, waits until the master unit reversely rotates. Start reversal. Next, when the child device rotates 180 degrees, the contact portion 18a comes into contact with the reverse rotation limit switch 17 and stops, and at the same time, the parent device also stops. In this way, the parent machine rotates forward and backward by 360 degrees while the child machine rotates forward and backward by 180 degrees. If the angle formed by the narrow angle β formed by the line connecting the center point of the horizontal bevel gear 14a and the two contact portions (18a, 18b) is 90 degrees instead of the above-mentioned 180 degrees, it is possible to perform 90-degree forward and reverse rotation. By setting the angle formed by the narrow angle β as appropriate, it is possible to perform forward and reverse rotation at an arbitrary angle.
[0029]
The switching time between forward rotation and reverse rotation can be arbitrarily set by a timer. If the switching time is set shorter than the time for the reversing substrate 15 to make one rotation, the reversing substrate 15 does not make one rotation. The normal and reverse rotations are alternately repeated. If the switching time is set longer than the time required for the reversing board 15 to make one rotation, the contact portion 18 attached to the horizontal bevel gear 14a alternately contacts the forward rotation limit switch 16 and the reverse rotation limit switch 17 as described above. As the motor turns on and off, the motor reverses, and the reversing board repeats the forward and reverse rotations in the same manner. In this case, it is necessary to prevent a failure due to heat generation of the motor by providing a standby time for switching between the forward and reverse rotations in consideration of the inertial rotation after the energization of the motor is turned off.
[0030]
It goes without saying that sequence control using a non-contact relay can be used instead of the electromagnetic relay. For example, using a Mitsubishi general-purpose sequencer F1-30MR type sequencer 27 manufactured by Mitsubishi Electric Co., Ltd., which is a PC (programmable controller) having a timer function, according to a predetermined ladder program stored in a storage device in the PC. It is possible to do. Further, in the reversing type spray blowing system of the present embodiment, one of the plurality of spray blowing devices is configured as a master unit, and the rest is configured as a slave unit. Although each of the spray blowers can be individually controlled so as to reverse the forward and reverse directions, it is preferable that the spray blower be configured as in this embodiment because the configuration is complicated.
[0031]
FIG. 10 is a perspective view illustrating the spray blower 3 in which the spray blower 4 is mounted on the opposite shaft side of the reversing board 15 of the reversing type gantry 1. The spray blower is hung on the ceiling of a barn or a house such as a piggery or a house, and sprays air or fine mist while rotating the spray blower while reversing 360 degrees, so that the temperature in a hot room, particularly in summer, can be reduced by 5 to 10 ° C. Can be reduced. In addition to spraying water, a disinfecting solution or the like can be sprayed. In addition, the spray blower is linked with a temperature sensor and humidity sensor to start spraying when the room temperature exceeds a predetermined temperature, and to stop spraying when the room temperature falls to a predetermined temperature and switch to blowing. You can also. The spray blower used here is not particularly limited as long as it is a commercially available device, and can be attached to the inverted substrate with bolts or the like.
[0032]
【The invention's effect】
