Air nozzles for cleaning the surface of manufactured objects.

In the production process of various products, after washing with a washing liquid in the final stage, it is necessary to remove the water remaining on the surface of the product after washing and to dry it. The process of removing moisture from the product until drying is required to be performed in a short time in order to improve the production efficiency of the product. In the drying process in the cleaning process of the product, it is usually dried by blowing off the liquid remaining on the surface of the product by high-pressure jet air.

Also, in the manufacturing industry of machine parts, etc., in the manufacturing process of machine parts, etc., the dust, dust, residual cutting oil or release agent, etc. adhering to the surface of the manufactured object are generally removed with a cleaning solution. After cleaning, blowing and removing with an air gun, or blowing and removing with an air gun without cleaning with a cleaning solution.

Here, as the cleaning process that must be performed with the cleaning solution and Manufacturers of the subsequent drying process, specifically, there are material trays for accommodating food, clothing, machine parts, etc., and housings for hard disks (HDDs), and cases for accommodating the hard disks by resin molded products. There are also other resin molded products, machined products, etc. Moreover, as a specific example of a material tray, there exists a resin-made container for the lunch box sold in a convenience store, a supermarket, etc. for shelters. In addition, as the material tray, it is a container used to protect the semiconductor wafers in the semiconductor wafer shipping process, so the material tray is also washed with warm water, and such items are also the object of the drying process.

Furthermore, in the machine manufacturing industry, in the production site, the oil stains, dust and debris of the above-mentioned manufactured products are washed with a jet cleaning liquid, and then the water is blown off with the air, and such a process is frequently performed. Wash and dry. Therefore, there are particularly useful devices for blowing off the cleaning solution of the product during the manufacturing process.

[Patent Document 1] Japanese Patent Laid-Open No. 2018-187530

In the conventional cleaning apparatus, for example, an air gun or the like exists. In order to remove dust, dust, or residues such as residual cutting oil, etc., the manufactured product having irregularities on the surface of the material tray, etc., is washed with a cleaning solution, etc. After that, most of the moisture remaining on the surface can be dried by the aforementioned air gun. However, it is difficult to substantially completely dry the cleaning solution remaining in the depressions of the uneven surface of the product.

Therefore, in order to dry the cleaning solution almost completely, the product is hung upright, and the cleaning solution is transported in such a way that the cleaning solution naturally falls downward from the product and flows out, or it is sprayed for a long time. air, or various means of raising the temperature of the air. However, such operations are extremely inefficient, and thus take up a lot of time in the cleaning process of the product.

In addition, the means of cleaning and drying as described above require a large number of operators, and also require a large number of related equipment such as air compressors, and the equipment has to be expanded, so it is also a great deal in terms of automation and cost. burden. In recent cleaning devices, although the above-mentioned problems can be solved, it is difficult to completely dry the surface of the product, not to mention actively scouring out the depressions remaining in the grooves, holes, etc. of liquids and dusts, so further development is required.

Furthermore, as in the rotary wave nozzle described in Patent Document 1, a component of the jetting force generated by jetting air from the nozzle is developed to rotate the jetting portion together with the rotary body, and after cleaning During the drying operation, wavy or intermittent jet air is sprayed to blow off moisture such as cleaning liquid. However, in this type of nozzle, as can be seen from the graph showing the relationship between the number of revolutions (rotational speed) of the rotating body and the drying quality in FIG. After the number of revolutions, the fluctuation or intermittent effect of the air injection will deteriorate, and the drying quality (also referred to as drying performance) may deteriorate due to continuous air injection.

In Patent Document 1, the following problems are suggested for the conventional ones of the same type. To explain this problem, that is, the rotating wave nozzle has the characteristic of being easy to increase the number of revolutions because the rotating shaft is rotatably supported by the bearing and can be easily rotated even with low-pressure compressed air. However, drying quality deteriorates at high spin numbers. That is, between the number of revolutions of the rotary wave nozzle and the drying quality, when the number of revolutions increases beyond the optimum value, it becomes difficult to blow off the droplets efficiently.

In addition, until the rotation number reaches the optimum value, the rotary wave nozzle is provided so that the compressed air is blown to the workpiece in a wave shape (periodically, intermittently), so that the droplets can be blown off efficiently. However, when the number of revolutions exceeds the optimum value, it is pointed out that the interval of the compressed air blown out due to the wavy shape gradually becomes shorter, and the compressed air cannot be pulsated after a while. In this case, since the compressed air is continuously sprayed, the drying quality is reduced (please refer to Fig. 11). Furthermore, it has also been pointed out that if the number of revolutions of the rotary wave nozzle is increased, the life of the bearing is shortened, and there is also a problem that the noise is increased.

In Patent Document 1, for this reason, there is provided a number of revolutions suppressing means for suppressing an excessive increase in the number of revolutions (rotational speed) of the rotating body. However, the rotation number suppressing means in Patent Document 1 has a very complicated structure, so there is a risk that it is sufficiently difficult to manufacture and that it becomes expensive. Yu.

Herein, an object of the present invention (technical problem to be solved) is to provide an air nozzle having a very simple structure that includes not only the moisture remaining on the surface of the member but also the moisture remaining in the depressions. It can be actively scooped out, and it is easy to blow and dry the attached liquid or the attached oil mixed with oil and dust, and can effectively blow off dust such as dust and other dust, and it can be used to suppress the rotation rate. means of excessive ascent.

Here, in order to solve the above-mentioned problems, the inventors have made careful research through repeated efforts. By applying the invention of claim 1, an air nozzle is made, which is provided with a fixed body and a rotating body; the fixed body has: a circular The cylindrical casing part has an opening at one end in the axial direction, and a fixed base part, which is connected to the other axial end side of the cylindrical casing part, and has a cylindrical through part formed inside; the rotating body has: A rotating base, which is formed with an air flow path, and a spray pipe portion, which is installed on the rotating base and along the rotation direction of the rotating base, and the air spraying direction is inclined with respect to the axis of the rotating base, and the control A pipe portion having the same number and shape as the spray pipe portion, the spray direction of which is inclined toward the opposite side of the air spray direction of the spray pipe portion with respect to the above-mentioned axis, and a circular plate portion, which is installed on the above-mentioned The rotating base is provided with injection holes through which the respective front ends of the injection pipe part and the control pipe part are inserted; The angle of the inclination of the air injection direction from the front end of the injection pipe portion can be changed, and the injection pipe portion is provided to be locked and fixed at a desired position and the lock and fixation can be released; the control pipe The inclination angle relative to the axis line can be changed, and the control pipe part is set to be able to be locked and fixed and the locking and fixing can be released. The above-mentioned problems are solved by setting the rotation control forces of the pipe parts in opposite directions and setting the rotation propulsion force to be larger than the rotation control force.

The above-mentioned problem is solved by using the invention of claim 2 as the air nozzle according to claim 1, wherein the spray pipe portion and the control pipe portion are each provided with two pieces.

According to the invention of claim 3, as the air nozzle according to claim 1 or 2, wherein the injection pipe portion and the control pipe portion are arranged at equal intervals along the circumferential direction of the rotation base, Thereby, the above problem is solved.

By applying the invention of claim 4, as the air nozzle according to claim 1 or 2, the two spray pipe portions are positioned on both sides in the radial direction of the rotation base portion, and the control pipe portion is positioned on the The above-mentioned problem can be solved by the structure of the position orthogonal to the said two said injection pipe parts.

By applying the invention of claim 5 as the air nozzle according to claim 1 or 2, wherein the changeable range of the angle of the inclination of the control pipe portion is 0 to 20 degrees with respect to the axis, Thereby, the above problem is solved.

In the invention of claim 1, a fixed body and a rotating body are provided, and a rotating base of the rotating body is provided with a spray pipe portion along the rotating direction of the rotating base, and the air spraying direction is relative to the rotation direction of the rotating base. The axis line is inclined, and the control pipe portion is inclined relative to the axis line in the direction opposite to the air spray direction of the spray pipe portion; the control pipe portion is changeable and can be fixed relative to the axis The inclination angle of the center line. Thereby, with an extremely simple structure, it is possible to easily adjust the rotation number (rotation speed) of the rotating body under the spraying of air from the spray pipe, and to easily set the maximum drying quality for the product. optimal number of spins.

In particular, when the number of rotations (rotation speed) of the rotary body is excessively increased, the drying quality of the product (workpiece) or the efficiency of the drying operation may be degraded by the air jetted from the air nozzle. Even in such a case, by providing the control pipe portion whose spray direction is inclined toward the side opposite to the air spray direction of the spray pipe portion with respect to the axis of the rotation base of the rotating body, the control pipe portion can be directed toward the same The direction of the injection from the injection pipe portion is the opposite direction.

By the above technique, the rotation number (rotation speed) of the rotating base can be suppressed from increasing excessively, the rotation base can be set to an appropriate rotation number (rotation speed) and the state can be maintained, and ( The cleaning liquid, etc.), or the blowing effect of dust, oil, etc., is the best, and the drying quality can be extremely good. Again, controlled by The air injection by the pipe part also contributes to drying of the product (workpiece), and a more reliable drying operation can be performed together with the drying operation of the injection pipe part.

Furthermore, in the invention of claim 1, by making the spray pipe part rotatable for the air discharge part of the rotating base of the rotating body, the wind force of the spray air from the spray pipe part during drying operation can be adjusted. In the invention of claim 2, since the spray pipe part and the control pipe part are each provided with two structures, the most stable drying operation can be performed.

With the invention of claim 3, the injection pipe portion and the control pipe portion are arranged at equal intervals along the circumferential direction of the rotating base, and under this structural condition, the rotating body can have the most favorable rotational balance, so Vibration during rotation can be prevented or minimized.

According to the invention of claim 4, the two ejection pipe portions are located on both sides of the rotation base in the radial direction, and the control pipe portion is located at one of the positions orthogonal to the two ejection pipe portions. Therefore, it is possible to stably perform the drying operation by the jet air of the two jet pipes.

By setting the changeable range of the angle of the inclination of the control pipe portion to be 0 degrees to 20 degrees with respect to the axis of the invention of claim 5, the number of rotations (rotation speed) can be suppressed to be Best state.

The ejection pipe portion 41 mainly has the functions of drying the product (workpiece) 9 and rotating the rotating body A2. The control pipe portion 42 has a function of suppressing the rotation number (rotation speed) of the rotary body A2 driven by the injection pipe portion 41 . First, one or two or more of the injection pipe portion 41 and the control pipe portion 42 are respectively attached to the rotating cylindrical portion 31 . As the specific number of the injection pipe portion 41 and the control pipe portion 42 , the injection pipe portion 41 and the control pipe portion 42 may be suitable.

However, the respective numbers of the injection pipe parts 41 and the control pipe parts 42 are not limited to the above, and the number of the injection pipe parts 41 and the number of the control pipe parts 42 may be set. Generally, it is preferable that the number of the injection pipe parts 41 is the same as the number of the control pipe parts 42 , or the number of the injection pipe parts 41 is larger than the number of the control pipe parts 42 .

In the description of the first embodiment of the present invention, the number of the injection pipe portion 41 and the number of the control pipe portion 42 is two respectively (refer to FIGS. 1 to 5). The jet pipe portion 41 is a pipe member that circulates air to generate jet air for cleaning and jet air for propulsion that becomes a rotational force for rotating the rotary body A2.

[Please refer to Figure 2 (B)].

In addition, the vicinity of the front end injection port 41c of the injection pipe portion 41 is inclined in a direction opposite to the rotation direction set by the rotary body A2 during operation (it may also be referred to as a reverse direction) so as to perform air injection. Specifically, the vicinity of the front end injection port 41c of the injection pipe portion 41 is configured to have an inclination angle θf with respect to the axis L along the outer peripheral direction of the rotary base 3 . Here, the inclination angle θf in the injection pipe portion 41 may also be referred to as the injection angle θf.

Moreover, as mentioned above, the injection pipe part 41 arranges or inserts the base part 41j in the air discharge part 31c, and implements the structure which can change the inclination angle (theta)f by making it rotatable.

The rotation direction of the rotating body A2 is set to either a clockwise direction or a counterclockwise direction when viewed from the opening side (front side) of the air nozzle An. Furthermore, if the injection force of the air (gas) injected from the front end injection port 41c is Ff, the direction of the injection force Ff is inclined with respect to the axis L of the air nozzle An as described above. Angle θf [please refer to Fig. 5(A)]. Therefore, the drying jet force for drying (cleaning) the product 9 becomes Ff. cosθf. The dry spray force Ff. cosθf is a force in the same direction as the axial direction of the axis line L.

Also, the rotational propulsion force used to rotate the rotating body A2 becomes Ff. sinθf [please refer to Fig. 5(A)]. The rotational propulsive force Ffsinθf is perpendicular to the axis L and is a force along the outer peripheral direction of the rotational base 3 . In this way, the rotating body A2 of the air nozzle An is generated by the jetting force Ff of the air (gas) jetted from the jetting port 41c at the front end of the jetting pipe portion 41 Rotational propulsive force Ff as a component force. sinθf, the rotating body A2 can be rotated together with the rotating base 3 (refer to FIG. 4).

The inclination angle θf can be variably set within a predetermined range, specifically, within the range of the minimum angle and the maximum angle. The range of the minimum angle is about 10 degrees, and the maximum angle is about 30 degrees. The preferred range of the minimum angle to the maximum angle is about 15 degrees to about 20 degrees, and suitably about 15 degrees. In addition, the range of the inclination angle θf can be adjusted as described above.

The injection pipe portion 41 is constituted by a linear portion 41a, a meandering portion 41b, and a base portion 41j [please refer to Fig. 1(A), Fig. 2(B), etc.].

The locking device 43 is specifically a nut, and the nut is used as a locking nut. In order to put the front end injection port of the injection pipe portion 41 Since the injection angle of 41c is set at a desired angle, the base portion 41j inserted into the air discharge portion 31c is rotated, and the lock 43 serving as the lock nut is moved to the air discharge portion 31c at the desired position. By directly keeping the state locked at the opening of the injection pipe portion 41, the injection angle of the injection port 41c at the front end of the injection pipe portion 41 is locked and fixed at the desired position [please refer to Fig. 2(B), Fig. 3 Figure, Figure 5, etc.].

The inclination angle θr is variable, and the inclination angle θr can be appropriately set [please refer to FIG. 5(B)].

Furthermore, when the injection force of the air (gas) injected from the front end injection port 42c is Fr, the direction of the injection force Fr is an angle θr inclined with respect to the axis L [see Fig. 5 (B )]. Therefore, the drying jet force for drying (cleaning) becomes Fr. cosθr. Also, the restraining force for restraining the rotation number (rotation speed) of the rotating body A2 becomes Fr. sinθr.

The inclination angle (injection angle) θr of the front end injection port 42c of the control pipe portion 42 is set to be smaller than the inclination angle (injection angle) θf of the front end injection port 41c of the injection pipe portion 41 . In addition, the inclination angle θr in the control pipe portion 42 is set so as to start from the same direction as the axis line L. As shown in FIG. That is, the inclination angle θr includes 0 degrees as an angle with respect to the axis line L. As shown in FIG.

The circular plate portion 5 is for allowing the injection air from the front end injection port 41c of the injection pipe portion 41 and the front end injection port 42c of the control pipe portion 42 to pass through. pass. Moreover, the disk part 5 is connected to the front end surface part 31b of the rotating cylindrical part 31 of the rotating base 3 so that the center of rotation of the disk part 5 and the rotating base 3 may coincide or substantially coincide. At this time, a cylindrical collar portion 53 is provided between the front end surface portion 31b and the above-mentioned circular plate portion 5 in order to provide a predetermined interval.

In addition, the above-mentioned collar portion 53 may be integrally formed on the front end surface portion 31 b of the rotating cylindrical portion 31 of the rotating base portion 3 .

The disk part 5 is set so that it may be located in the axial direction rear side rather than the opening peripheral edge of the opening part 2a of the cylindrical case part 2 of the fixed main body A1. In addition, the disc portion 5 has a structure that is positioned more inward than the opening portion 2 a of the cylindrical case portion 2 , that is, to the rear side of the cylindrical case portion 2 . Further, a substantially flat cylindrical cavity S having a depth dimension H from the opening 2a is formed in the opening of the cylindrical case 2 by the opening 2a of the cylindrical case 2 and the disk portion 5 side [please refer to Figure 1 (A)].

The aforementioned depth dimension H is an amount for setting the volume of the void chamber S, and by appropriately adjusting the depth dimension H, the volume can also be appropriately set. Specifically, the depth dimension H of the void chamber S, compared to the cylindrical shell The height of the whole part 2 is a little. In addition, the outer peripheral edge 5a of the circular plate part 5 is provided so that it may become a non-contact state with the inner peripheral side of the cylindrical side wall plate part 21 of the cylindrical case part 2.

In the disc part 5, the injection hole part 51 is formed in the position close|similar to the outer peripheral edge side. The ejection hole portions 51 are formed in the disc portion 5 in the same number as the ejection pipe portions 41 and the control pipe portions 42 . The front end injection port 41 c of the injection pipe portion 41 and the front end injection port 42 c of the control pipe portion 42 are located in the injection hole portion 51 . Specifically, the front end injection port 41c of the injection pipe portion 41 and the front end injection port 42c of the control pipe portion 42 are the hole portions 51 for penetrating injection. In this penetration state, the front end injection port 41c and the front end injection port 42c only need to pass through the injection hole portion 51 by a small amount.

The front-end|tip injection port 41c of the injection pipe part 41 is a structure which does not exceed the opening part 2a of the cylindrical case part 2 [refer FIG. 1 (A), (C)]. That is, the front end injection port 41c of the injection pipe portion 41 and the front end injection port 42c of the control pipe portion 42 are not located inwardly beyond the opening portion 2a of the cylindrical case portion 2, and do not protrude outward. side situation. The injection hole portion 51 is formed as an elliptical through hole, or formed to be larger than the portion of the front end injection port 41c and the front end injection port 42c that penetrates through the injection hole portion 51, or is not shown in the figure. In addition, the outer peripheral edge of the disc portion 5 may be formed by a substantially U-shaped cutout having an open portion.

The assembly of the stationary body A1 and the rotating body A2 in the air nozzle An of the present invention will be described. Two bearings 34 are provided in the air nozzle An. First, the first bearing 34 is inserted into the fixed body A1 from the opening on the rear side in the axial direction of the fixed base 1, then the spacer 35 is inserted, and then the spacer 35 is inserted. The second bearing 34 .

Next, the rotating base 3 of the rotating body A2 is inserted into the inner peripheral sides of the first and second bearings 34 . The spacer 35 is two cylindrical rings, one of which is installed along the inner peripheral side of the cylindrical penetration portion 11b of the fixed cylindrical portion 11 of the fixed body A1, and the other is installed along the rotating body A2 is attached so as to rotate the cylindrical side surface portion 31a of the cylindrical portion 31 (refer to FIG. 1).

Moreover, the fixing flange portion 12 for connection is fixed to the rear side end portion of the fixing base 1 of the fixing body A1 by means of a fixing tool 13 such as a screw, so that the first and second bearings 34 and the spacer 35 are fixed to the body A1 between the fixed base 1 and the rotating base 3 of the rotating body A2. Furthermore, the rotating flange 32 is fixed to the rear end of the rotating cylindrical portion 31 of the rotating body A2 at the fixing through hole 12a of the connecting fixing flange 12 with a fastener 33 such as a screw. Thereby, the rotating body A2 is rotatably mounted relative to the fixed body A1, and the rotating body A2 rotates with the axis L as the rotation center line (refer to FIGS. 1 and 3).

In the rotating body A2, there is an embodiment in which a container portion 36 having a flat cylindrical shape is provided with a void portion 36b therein (refer to FIGS. 1 and 3). The container portion 36 is formed in a substantially doughnut or life buoy shape, and has a hollow space portion 36b inside. The container portion 36 is fixed to the rotary base portion 3 of the rotary body A2, and is provided at a position close to the closing plate portion 22 of the cylindrical case portion 2 of the stationary body A1.

The container part 36 rotates together with the rotating body A2. An annular insertion through hole 36a is formed on the surface of the container portion 36 on the side close to the closing plate portion 22 of the cylindrical case portion 2, and serves as a shaft for fixing the cylindrical portion 11 of the above-mentioned fixed body A1. The front end portion toward the opening side is inserted into the insertion The structure of the through hole 36a is used (please refer to Fig. 1). A gap is formed between the inner peripheral edge of the insertion through hole 36a of the container portion 36 and the outer periphery of the stationary cylindrical portion 11 of the stationary base portion 1, and they are not in contact with each other. A bearing 34 provided between the fixed body A1 and the rotating body A2 is disposed at the front end portion of the fixed cylindrical portion 11 on the axial opening side.

That is, around the position of the bearing 34 installed between the stationary body A1 and the rotating body A2, there is a configuration in which an annular gap 36b is surrounded by the container portion 36 (refer to FIG. 1 ). , Figure 3). Moreover, the grease that leaks from the bearing 34 , such as grease or lubricating oil, and drips from the space between the stationary body A1 and the rotating body A2 can be accumulated in the space portion 36 b of the container portion 36 .

That is, the container part 36 is a storage container for storing the leaked grease or lubricating oil. In this way, it is possible to prevent the contamination of oil and grease from spreading into the cylindrical case portion 2, and to prevent the product 9 from being soiled by the drying operation of the product 9. However, it does not matter if the air nozzle An is not provided with the container portion 36 .

Next, the operation of the air nozzle An and the structure for suppressing an excessive increase in the number of revolutions (rotation speed) will be described. The air nozzle An can be used to rotate the rotary body A2 by adjusting the inclination angle (spray angle) θf of the jet port 41c from the front end of the jet pipe portion 41 of the rotary body A2 with respect to the axis L of the air jet. Propulsion Ff. sinθf varies [please refer to Fig. 5(A)]. That is, if set in such a way that the inclination angle θf with respect to the axis L is reduced, the rotational propulsive force Ff used to rotate the rotating body A2. sinθf will become smaller, so the rotation speed of the rotating body A2 will be Smaller and slower, and the number of rotations (rotation speed) is also reduced, the rotation speed of the rotary body A2 can be reduced. However, the drying jet force Ff. The cosθf becomes larger and the drying force increases.

Also, if the inclination angle θf is set to be larger with respect to the axis L, the rotational propulsive force Ff used to rotate it. sinθf will become larger. As a result, the rotational speed of the rotary body A2 becomes larger and faster, and the number of rotations (rotation speed) also increases, so that the rotational speed of the rotary body A2 can be accelerated. However, the dry jet force Ff. cosθf will become smaller and reduce the drying force.

In general, the normal air nozzle An for drying operation has smooth rotation performance because the rotating part provided with the air injection pipe is supported by a bearing, so that the rotation speed of the rotating part can be easily increased. In particular, there is a problem that drying quality or drying efficiency deteriorates in a high rotation number region where the rotation speed is excessively increased. That is, between the rotation number of the rotating part of the air nozzle An and the drying quality, until the rotation number at the rotation speed reaches its optimum value, although the drying efficiency or drying quality can be gradually improved, if the rotation speed is If the number of rotations exceeds this optimum value and continues to rise, it becomes difficult to efficiently blow off the droplets (see Fig. 11).

That is, until the number of revolutions reaches this optimum value, the compressed air can be blown onto the workpiece in a wave-like (periodic, intermittent) manner, so that droplets can be blown off efficiently. However, if the rotation speed is excessively increased and the rotation number exceeds the optimum value, the interval of the compressed air blown out in a wave shape gradually becomes shorter, and the compressed air will not be waved after a while. here In this case, since the compressed air is continuously sprayed, the drying quality and drying efficiency are reduced. In addition, when the number of revolutions of the rotary wave nozzle is increased, the life of the bearing is shortened, and there is a problem that the noise is increased.

In the present invention, it is possible to prevent the fact that the rotation speed of the rotating body A2 in the air nozzle An is excessively increased, and as described above, the efficiency of the drying operation of the product 9 by the air sprayed from the air nozzle An is deteriorated and the drying operation cannot be performed smoothly. In addition, it is possible to prevent the bearing and other members from being burdened due to an excessive increase in the rotational speed of the rotating body A2.

That is, there are appropriate numerical values for the rotational speed and the number of rotations of the rotary body A2. In addition, it is also possible to adjust the rotational speed of the rotating body A2 to be an optimum state according to the shape and size of the product 9 . In such a case, in the present invention, the air injection of the control pipe portion 42 can resist the air injection of the injection pipe portion 41, thereby suppressing the increase of the rotation number (rotation speed) of the rotary body A2 to prevent an excessive rotation number ( rotation speed), the rotation number (rotation speed) of the rotary body A2 can always be maintained in an optimum state.

Thereby, the jet air jetted from the jetting outlet 41 at the front end of the jetting pipe portion 41 can be jetted on the product 9 in a wave shape (periodic, intermittent), and droplets can be efficiently blown off. The effect of blowing off liquid (such as cleaning liquid) adhering to the product 9, dust, oil stain, etc., and the effect of drying operation can be optimized.

In the following, the number of rotations (rotation) is suppressed by the control pipe portion 42 speed) will be explained. Here, in the rotating body A2, two injection pipe parts 41 and two control pipe parts 42 are provided, respectively, and the two injection pipe parts 41 and the two control pipe parts 42 form a substantially cross shape, and the injection pipe part 41 Those having the same shape and the same inner diameter as the control pipe portion 42 will be set and described.

The injection pipe portion 41 and the control pipe portion 42 are inclined in opposite directions to each other along the outer circumference of the rotary base 3 with respect to the axis L of the rotary base 3 . In addition, the relationship between the inclination angle θf of the injection pipe portion 41 and the inclination angle θr of the control pipe portion 42 is, as described above, 0°≦θr<θf.

Here, the rotational propulsion force generated by the jet pipe portion 41 in the rotating body A2 is Ff. sinθf, the rotational control force generated by the control tube portion 42 is Fr. sinθr [please refer to Fig. 5(B)]. The rotational propulsion force generated by the injection pipe portion 41 and the rotational control force generated by the control pipe portion 42 are, Ff. sinθf>Fr. sinθr.

Also, the rotational propulsion force Ff generated by the injection pipe portion 41. sinθf, and the rotational control force Fr generated by the control tube portion 42. sinθr is the opposite direction (reverse direction) to each other. Therefore, the rotation control force of the control pipe portion 42 can be suppressed from excessively increasing the rotation number (rotation speed) of the rotary body A2 with respect to the rotation propulsion force of the injection pipe portion 41, and the rotation number (rotation speed) of the rotary body A2 can be reduced. Always be in the best condition. In addition, the control pipe portion 42 can adjust the inclination angle θr with respect to the axis L of the rotary base 3, and by changing the inclination angle θr, a desired rotation number (rotation speed) of the rotary body A2 can be set.

The above description is applicable to the same shape in the rotating body A2. There are two conditions for each of the injection pipe portion 41 and the control pipe portion 42 to be provided in the same shape. Therefore, as shown in FIG. 7 , when two injection pipe parts 41 and one control pipe part 42 are provided in the rotary body A2, since the structure for suppressing the number of revolutions (rotation speed) is different, it is necessary to adapt to each case. In this case, the inclination angle θr of the control pipe portion 42 must be appropriately changed.

That is, with respect to the rotational propulsion force Ff generated by the two injection pipe portions 41 . sinθf is 2, and the rotational control force Fr generated by a control tube portion 42. sinθr is one. Therefore, in order to make the rotation number (rotation speed) of the rotating body A2 appropriate, it is necessary to control the rotation control force Fr generated by the control pipe portion 42. The value of sin θr is adjusted to be larger, so that the inclination angle θr with respect to the axis L is also increased. In addition, when the drying operation of the product 9 is performed by the air nozzle An, although the spray pipe part 41 plays the role, the spray air generated by the control pipe part 42 can also participate in the drying operation.

In addition, FIG. 8 is a case where the inclination angle θr of the control pipe portion 42 with respect to the axis L is set to 0 degrees. That is, the air injection direction from the front end injection port 42c of the control pipe portion 42 is in line with the axial center line L. As shown in FIG. In this case, almost all of the jet air jetted from the control pipe portion 42 is used for the drying operation. In particular, it is more effective when the distance between the air nozzle An and the product 9 which is a drying object is large.

As the product 9 in this case, for example, a deep-bottomed container (polymeric plastic cylinder, jug-shaped one). In addition, when the inclination angle θr of the control pipe portion 42 is set to 0 degrees with respect to the axis line L, since the jet air ejected from the control pipe portion 42 is along the axis line L, it is blown against the axis line L with the full injection force. For the product 9, the reaction force at this time is the control force formed by the control pipe portion 42. Therefore, the excessive increase of the rotation number (rotation speed) of the rotary body A2 can be suppressed, and the rotary body A2 can be maintained at the optimum rotation number (rotation speed) [Please refer to Figure 8 (A)] .

The air nozzle An in the present invention is connected to the air nozzle base 6 and used as an air nozzle unit (refer to FIG. 9 ). Specifically, a plurality of air nozzles An are attached to the air nozzle base 6 and used. In addition, the air nozzle unit is a frame body 7 (refer to FIG. 10 ) assembled in the air jet drying system.

The blower 8 is a manufacturer of compressed air such as an electric air compressor, and is used to supply compressed air from the blower 8 to the air nozzles An attached to the air nozzle base 6 through the air nozzle base 6 . (Please refer to Figure 9).

The base body 61 is formed in a substantially casing shape, and an air chamber 64 through which compressed air circulates is provided therein. The air nozzle unit composed of the plurality of air nozzles An and the air nozzle base 6 is installed at a predetermined position of the frame body 7 of the air jet drying system through the mounting portion 65 of the air nozzle base 6 .

The base body 61 is installed in the drying operation area by clamping bolts, nuts and other fixtures. The base body 61 is provided with a flat installation surface 61a to which the air nozzles An can be connected and installed, and the installation surface 61a is provided with one or more air supply ports 63 [please refer to FIG. 9].
