Description

Air nozzle

The present invention relates to the use of spraying air (gas) pressure to blow off the remaining liquid cleaned by the cleaning liquid or the attached dust, dust, oil stains, etc., for the manufactured product during the manufacturing process or after the manufacturing is completed. An air nozzle that cleans the surface of the product.

In the manufacturing process of various manufactured products, in the final stage, after washing with a washing liquid, the water remaining on the surface of the product after washing must be removed and dried. The process of removing moisture from the product to drying is also required to be performed in a short time in order to improve the manufacturing efficiency of the product. The drying process in the washing process of the manufactured product usually uses high-pressure jet air to blow off the liquid remaining on the surface of the manufactured product to dry it.

Moreover, in the manufacturing industry of machine parts, etc., in the manufacturing process of machine parts, etc., it is generally used to remove dust, dust, residual cutting oil or release agent, etc., which adhere to the surface of the manufactured product with a cleaning solution. After washing, the air gun is used for blowing and removing, or the cleaning solution is not used for blowing and removing with an air gun.

Here, as a manufactured product that requires a washing process and a subsequent drying process with a cleaning solution, specifically, there are resin molded products that contain material trays for food, clothing, mechanical parts, etc., and hard disks. There are other resin molded products, machined products, etc., in the case of HDD and the material tray that contains the case of HDD. In addition, as a specific example of the material tray, there are resin containers used for lunch sold in shelters such as convenience stores or supermarkets. In addition, as a material tray, it is a container used to protect semiconductor wafers during the semiconductor wafer shipping process. Such material trays are also rinsed with warm water, and such items become the object of the drying process.

Furthermore, in the machinery manufacturing industry, in the production site, the oil, dust, and debris of the aforementioned manufactured products are washed with spray cleaning liquid, and then the moisture is blown off by the air.

[The problem to be solved by the invention]

In the conventional washing device, for example, there is an air gun. In order to remove dust, dust, or remaining cutting oil and other residues from the surface of the material plate, etc., the product is washed with a cleaning fluid, etc., with the aforementioned air gun, although it can be used Most of the moisture remaining on the surface is dry. However, it is difficult to almost completely dry the cleaning solution remaining in the recesses of the uneven surface of the product.

Therefore, in order to perform the cleaning of the dry cleaning liquid almost completely, it is necessary to carry the product by hanging the product upright so that the detergent can naturally fall downward from the product and flow out, or spray it for a long time. Various methods such as air, or raising the temperature of the air. However, these operations are extremely inefficient, and therefore take a lot of time in the cleaning process of the manufactured product.

In addition, such cleaning and drying methods require a large number of operators and a large number of related equipment such as air compressors. The equipment has to be expanded. Therefore, it has become a big deal in terms of automation and cost. Burden. In recent cleaning devices, although the above-mentioned problems can be solved, it is hard to say that even the surface of the manufactured product can be dried easily and completely, not to mention actively scouring out the recesses remaining in the grooves, holes, etc. The liquid, dust, and so on are required for further development.

Furthermore, as in the rotating wave nozzle in Patent Document 1, it was developed to use the component of the spray force generated by the spray air from the nozzle as the rotating force to rotate the spray part and the rotating body together. After washing, In the drying operation, the undulating or intermittent jet air is sprayed to blow off the moisture such as the cleaning liquid. However, in this type of nozzle, as shown in the graph showing the relationship between the number of rotations (rotation speed) of the rotating body and the drying quality in Figure 11, it can be seen that when the number of rotations (rotation speed) of the rotating body increases too much and exceeds a certain level After the number of revolutions, the volatility or intermittent effect of the air injection will deteriorate, and the continuous air injection may cause the deterioration of the drying quality (also referred to as the drying performance).

In Patent Document 1, the following problems are suggested for those of the same type in the past. To explain this problem, that is, the rotating wave nozzle is rotatably supported by a bearing because its rotating shaft can be easily rotated even with low-pressure compressed air, so it has the characteristic that it is easy to increase the number of rotations. However, the drying quality will deteriorate at a high number of rotations. That is, when the number of revolutions of the undulating nozzle and the drying quality rises above the optimum value, it becomes difficult to blow off the droplets efficiently.

In addition, until the number of rotations reaches the optimum value, the undulating rotation nozzle is provided to blow compressed air onto the workpiece in a undulating (periodic, intermittent) manner, so that droplets can be blown off efficiently. However, if the number of revolutions exceeds the optimal value, it is pointed out that the interval of compressed air blown out due to the wave form gradually becomes shorter, and after a while, the compressed air cannot produce wave. In this case, since compressed air is sprayed continuously, the drying quality is reduced (please refer to Figure 11). Furthermore, it has also been pointed out that if the number of rotations of the rotating wave nozzle becomes higher, the life of the bearing will be shortened, and there will also be a problem of increased noise.

In Patent Document 1, because of this, it is provided with a rotation number suppression means useful for suppressing an excessive increase in the rotation number (rotation speed) of the rotating body. However, the rotation number suppression means in Patent Document 1 has an extremely complicated structure, and therefore, there is a fear that it is sufficiently difficult to manufacture and may become expensive.

Here, the object of the present invention (technical problem to be solved) is to provide an air nozzle with a very simple configuration of the following means: not only for the moisture remaining on the surface of the part, but also for the moisture remaining in the depression It can be actively washed out, and it is easy to blow away the attached liquid or the attached oil mixed with oil and dust, and it can effectively blow off dust such as dust, and it can be used to suppress the number of rotations. Means of excessive rise. [Technical means to solve the problem]

Next, the injection pipe portion 41 and the control pipe portion 42 will be described. The injection pipe part 41 mainly has the functions of drying the product (workpiece) 9 and rotating the rotating body A2. The control pipe section 42 has a function of suppressing the number of rotations (rotation speed) of the rotating body A2 driven by the injection pipe section 41. First, the injection pipe portion 41 and the control pipe portion 42 are each provided with one or two or more in the rotating cylindrical portion 31. As the specific number of the injection pipe portion 41 and the control pipe portion 42, it is suitable for the case where the injection pipe portion 41 and the control pipe portion 42 are each two (first embodiment), and the injection pipe portion 41 is two. When there is one control tube 42 (second embodiment).

However, the respective numbers of the injection pipe portion 41 and the control pipe portion 42 are not limited to the above, and the number of the injection pipe portion 41 and the number of the control pipe portion 42 may be set. Generally, it is preferable that the number of the injection tube portions 41 is the same as the number of the control tube portions 42 or the number of the injection tube portions 41 is more than the number of the control tube portions 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 will be two each (please refer to Figs. 1 to 5). The jet pipe portion 41 is a pipe member that circulates air to generate jet air for washing and jet air for propulsion that becomes a rotational force for rotating the rotating body A2. First, description will be given from the injection pipe portion 41 first. One end of the jet pipe portion 41 is a root joint 41j. The root joint 41j is inserted into the air discharge portion 31c of the rotating cylindrical portion 31, and the root joint 41j is rotatable in the circumferential direction in the air discharge portion 31c. The structure of the method [please refer to Figure 2 (B)].

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

Here, the so-called inclination angle θf refers to the direction of the jet force Ff of the air jetted from the tip jet port 41c of the jet pipe portion 41, and is along the rotation base 3 with the axis L as the reference. The direction of rotation, that is, along the outer peripheral surface of the rotation base 3, is an angle that is inclined in the opposite direction to the direction of rotation when the axis L is used as a reference [please refer to Fig. 5(A)].

The front end injection port 41c of the injection pipe portion 41 is implemented to be along the rotation direction of the rotating base 3 and having an inclination angle θf of the air injection direction with respect to the axis L of the rotating base 3 as described above. In addition, as described above, the injection pipe portion 41 is configured such that the root connecting portion 41j is arranged or inserted into the air discharge portion 31c, and is rotatable so that the inclination angle θf can be changed.

The rotation direction of the rotating body A2 is set to either the clockwise direction or the counterclockwise direction when viewed from the opening side (front side) of the air nozzle An. And, when the spray force of the air (gas) sprayed from the tip injection port 41c is set to Ff, the direction of the spray force Ff is, as described above, inclined with respect to the axis L of the air nozzle An Angle θf [please refer to Figure 5(A)]. Therefore, the dry spray force used to dry (wash) 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.

In addition, the rotational propulsion force used to rotate the rotating body A2 becomes Ff. sinθf[Please refer to Figure 5(A)]. The rotational propulsion force Ffsinθf is perpendicular to the axis L and is a force along the outer circumferential direction of the rotation base 3. In this way, the rotating body A2 of the air nozzle An generates a rotational propulsion force Ff as a component of the ejection force Ff of the air (gas) ejected from the front end ejection port 41c of the ejection pipe portion 41. sinθf, and the rotating body A2 can be rotated together with the rotating base 3 (please 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. Preferably, the 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 composed of a linear portion 41a, a zigzag portion 41b, and a root connecting portion 41j [please refer to Fig. 1 (A), Fig. 2 (B), etc.]. The continuous portion of the linear portion 41a and the meandering portion 41b is formed gently and continuously; the tip injection port 41c is located at the tip of the meandering portion 41b, and the root connecting portion 41j is located at the tip of the linear portion 41a. The root portion 41j is arranged or inserted into the air discharge portion 31c, and the inclination angle of the ejection direction of the tip ejection port 41c is set by the inclination angle of the bending portion 41b with respect to the axis L.

A male screw part 41d is formed in the root joint part 41j of the injection pipe part 41. As shown in FIG. In addition, a female screw part 31g is formed in the air discharge part 31c, and the male screw part 41d and the female screw part 31g have a structure capable of screwing. The root joint portion 41j of the injection pipe portion 41 is inserted into the air discharge portion 31c in a screwed state, and the root joint portion 41j is rotatable centered on the air discharge portion 31c [please refer to FIG. 2(B)]. In addition, a locking device 43 is provided on the external thread portion 41d.

The locking device 43 is specifically a nut, and the nut is used as a locking nut. In order to set the injection angle of the injection port 41c at the front end of the injection pipe part 41 at a desired angle, the root joint 41j inserted in the air discharge part 31c is rotated, and at a desired position, the locking nut The locking device 43 moves to the opening of the air discharge portion 31c, and by directly maintaining the locked state there, the spray angle of the spray port 41c at the front end of the spray pipe portion 41 is locked and fixed at the desired position [please Refer to Figure 2 (B), Figure 3, Figure 5, etc.].

Moreover, when the injection angle of the front end injection port 41c of the injection pipe portion 41 is to be adjusted again, the injection angle of the front end injection port 41c can be adjusted again by releasing the locked state by the locker 43. There is also an embodiment in which the inclination angle (injection angle) θf of the injection port 41c at the front end of the injection pipe portion 41 is fixed to a predetermined angle in advance. In this case, the inclination angle θf is set in the optimal range of about 15 degrees to about 20 degrees.

Next, the control pipe section 42 will be described. The shape of the control pipe portion 42 is the same as or substantially the same as that of the injection pipe portion 41, and the direction of the air injection of the control pipe portion 42 is the direction of the air injection of the above-mentioned injection pipe portion 41, which is always the opposite (reverse) direction ( Please refer to Figure 1, Figure 4, Figure 5, etc.). One end of the control tube 42 is a root joint 42j. The root joint 42j is an air discharge portion 31c inserted into the rotating cylindrical portion 31, and the root joint 42j is in the air discharge portion 31c so as to be able to face in the circumferential direction. It is constructed in a freely rotating way.

In addition, the injection port 42c at the front end of the control tube 42 has an inclination angle (injection angle) θr along the rotation direction of the rotating base 3, that is, along the outer peripheral surface, and inclined with respect to the axis L. The inclination angle (injection angle) θr is the inclination angle (injection angle) θf of the injection port 41c at the front end of the injection pipe portion 41, which is inclined in the opposite (reverse) direction with respect to the axis L. The control pipe portion 42 is also implemented so as to be rotatable by inserting its root portion 42j into the air discharge portion 31c like the injection pipe portion 41. The inclination angle θr is variable, and the inclination angle θr can be appropriately set [please refer to Fig. 5(B)].

In addition, when the injection force of the air (gas) injected from the tip injection port 42c is set to Fr, the direction of the injection force Fr is an angle θr that is inclined with respect to the axis line L [Please refer to Fig. 5 (B )]. Therefore, the drying spray force used for drying (washing) becomes Fr. cosθr. In addition, the restraining force for restraining the number of rotations (rotation speed) of the rotating body A2 becomes Fr. sinθr. In this way, the rotating body A2 of the air nozzle An generates propulsion as a component of the air (gas) ejected from the front end ejection port 41c of the ejection pipe portion 41 by the ejection force Ff for rotating it. Force Ff. sinθr, and the rotating body A2 can be rotated.

The inclination angle θr can be variably set within a predetermined range, specifically, within the range of the minimum angle and the maximum angle. The inclination angle (injection angle) θr of the injection port 42c at the front end of the control pipe portion 42 is set to be smaller than the inclination angle (injection angle) θf of the injection port 41c at the front end of the injection pipe portion 41. In addition, the inclination angle θr in the control tube 42 is set to start from the same direction as the axis L. That is, the inclination angle θr includes 0 degrees as an angle with respect to the axis L. In addition, the inclination angle θr is preferably an angle that is smaller than the inclination angle θf of the injection pipe portion 41 from 0 degrees.

That is θf>θr≧0 degrees.

The control pipe portion 42 has the same configuration as the injection pipe portion 41, and is composed of a linear portion 42a, a zigzag portion 42b, and a root portion 42j. The continuous portion of the linear portion 42a and the meandering portion 42b is gently and continuously formed; the tip injection port 42c is located at the tip of the meandering portion 42b, and the root connecting portion 42j is located at the tip of the linear portion 42a. The root portion 42j is arranged or inserted into the air discharge portion 31c, and the inclination angle of the ejection direction of the tip ejection port 42c is set by the inclination angle of the bent portion 42b with respect to the axis L.

The setting structure of the inclination angle (injection angle) θr in the control pipe portion 42 is the same as the structure of the inclination angle (injection angle) θf of the injection pipe portion 41 described above.

And, similarly to the injection pipe portion 41, the injection angle of the injection port 42c at the front end of the control pipe portion 42 is locked and fixed at a desired position. In addition, when the injection angle is to be adjusted again, the injection angle of the front end injection port 42c can be adjusted again as long as the lock state applied by the locker 43 is released.

In addition, in this patent specification, the inclination angle θf of the air injection direction of the front end injection port 41c of the injection pipe portion 41 with respect to the axial center line L is only referred to as the inclination angle θf of the injection pipe portion 41 situation. Similarly, there may be cases where the inclination angle θr of the air injection direction of the front-end injection port 42c of the control tube 42 with respect to the axis line L is simply referred to as the inclination angle θr of the control tube 42.

Here, in order to adjust the injection angle (inclination angle) θf in the injection pipe section 41 and the injection angle (inclination angle) θr in the control pipe section 42, there may be cases where an angle adjustment gauge 45 is provided (please refer to section Figure 6). The angle adjustment gauge 45 is a plate-shaped body and includes a reference side 45a and a reference inclined side 45b. The reference side 45a is a part for abutting against a part of the rotating body A2, and the reference inclined side 45b is a part for setting the inclination angle θf and the inclination angle θr of the injection pipe portion 41 and the control pipe portion 42, respectively.

Specifically, the reference inclined side 45b can be prepared to set multiple angles such as 5 degrees, 10 degrees, 15 degrees, and 20 degrees. Adjustment rule 45. In addition, when setting the inclination angles of the injection pipe portion 41 and the control pipe portion 42 respectively, an angle adjustment gauge 45 having the desired reference inclined side 45b is prepared to set each of the injection pipe portion 41 and the control pipe portion 42 Other setting angles.

Specifically, the locking device 43 of the injection pipe portion 41 or the control pipe portion 42 is loosened to be in a freely rotatable state. Then, the reference side 45a of the angle adjustment gauge 44 is brought into contact with a surface orthogonal to the axial direction, such as the bottom surface of the container portion 36, and the injection pipe portion 41 or the control pipe portion 42 is aligned along the reference slope 45b. Way to block. Then, the locker 43 is locked again to fix the injection pipe portion 41 and the control pipe portion 42 [please refer to Fig. 6(A)].

Next, the second embodiment of the present invention will be explained based on FIG. 7. In this second embodiment, the injection pipe portion 41 and the control pipe portion 42 are implemented as two injection pipe portions and one control pipe portion as described above. In this case, the two injection pipe portions 41 and 41 and one control pipe portion 42 have their respective root joint portions 41j and 42j arranged at equal intervals along the circumferential direction of the rotating base 3 as constituent members. In other words, it is arranged at equal angles based on the center of the diameter of the rotating base 3. Here, the root joints 41j and 42j are arranged at an interval of 120 degrees, with two injection pipes 41 and one control pipe. The portion 42 constitutes a substantially Y-shaped shape [please refer to Fig. 7(A)].

In addition, as a modification of the second embodiment, there is also an implementation such that two injection pipe portions 41, 41 are located on both sides in the diameter direction of the rotating base 3, and one control pipe portion 42 is located and connects the two injection pipes. The positions where the diameter lines of the rotation base 3 of the parts 41 and 41 are orthogonal to each other. In this case, the two injection pipe portions 41 and one control pipe portion 42 form a substantially T-shape [please refer to FIG. 7(B)]. That is, in this embodiment, the configuration is substantially the same as that in the first embodiment described above, in the configuration of the two injection pipe portions 41 and the two control pipe portions 42, the control pipe portion 42 is removed. The status of each.

In this modification of the second embodiment, a weight 44 may also be provided. In addition, in the state where the rotating base 3 is provided with one control tube 42b, the counterweight 44 is provided on the diameter line connecting the root joint 42j of the control tube 42 and the center of the diameter of the rotating base 3, and is provided on The position opposite to the control tube 42 [please refer to Fig. 7(B)].

The weight 44 is preferably approximately the same weight as the control tube portion 42. Specifically, it is a combination of a bolt and a nut for locking and fixing. When a bolt is used as the weight 44, the external thread 44b is screwed to the internal thread portion 31g formed in the air discharge portion 31c, and the bolt as the weight 44 is installed on the rotating base 3 [please refer to Figure 7 (B)].

By installing the counterweight 44, the counterweight 44 can evenly distribute the eccentric load caused by the injection pipe portion 41 and the control pipe portion 42 to the rotating base 3, and can prevent the rotating body A2 from vibrating during rotation. Stabilize the rotation. Although the shape of the control tube 42 is the same as or substantially the same as that of the injection tube 41, the shape of the control tube 42 can be different from that of the injection tube 41, or it can also be provided as needed. The inner diameter of the tube is different.

The disc portion 5 is used to allow the jet air from the tip jet port 41c of the jet tube portion 41 and the tip jet port 42c of the control tube portion 42 to pass through. In addition, the disk portion 5 is connected to the front end surface 31b of the rotating cylindrical portion 31 of the rotating base 3 so that the rotating center of the disk portion 5 and the rotating base 3 coincide or substantially coincide. At this time, in order to provide a predetermined interval between the front end face 31b and the disc part 5, a cylindrical collar part 53 is provided. The front end face 31b and the disc part 5 and the collar part 53 are formed by It is fixed with 54 screws and other fixtures (please refer to Figure 1).

At the center of the diameter of the circular plate portion 5, there is formed a through hole 5n for mounting, and the threaded portion of a fixture 54 such as a screw penetrates through the through hole 5n for mounting, and the fixture 54 is screwed to the collar portion 53 Threaded hole. In the rotating body A2, the circular plate portion 5 and the injection pipe portion 41 are used as a rotation axis along the axis line L to make the rotation base 3 perform a rotation operation, and the control pipe portion 42 is used to control the number of rotations in the rotation operation ( The excessive increase in the rotation speed) is suppressed. In addition, the collar portion 53 may be integrally formed on the front end surface 31b of the rotating cylindrical portion 31 of the rotating base 3.

The disc portion 5 is set so as to be positioned on the axially rearward side of the opening peripheral edge of the opening portion 2a of the cylindrical housing portion 2 of the fixed body A1. In addition, the circular plate portion 5 has a structure that is located more inside than the opening portion 2a of the cylindrical housing portion 2, that is, is located at the rear side of the cylindrical housing portion 2. Furthermore, by the opening 2a of the cylindrical casing portion 2 and the disc portion 5, a substantially flat cylindrical void space S whose depth dimension H from the opening portion 2a is H is formed in the opening of the cylindrical casing portion 2. Side [please refer to Figure 1 (A)].

The above-mentioned depth dimension H is an amount for setting the volume of the void space S, and by appropriately adjusting the depth dimension H, the volume can also be appropriately set. Specifically, the depth dimension H of the void space S is a small amount compared to the height of the entire cylindrical casing portion 2. In addition, the outer peripheral edge 5a of the circular plate portion 5 is provided so as to be in a non-contact state with the inner peripheral side of the cylindrical side wall plate portion 21 of the cylindrical housing portion 2.

In the circular plate portion 5, a spray hole 51 is formed at a position close to the outer peripheral edge side. The injection hole 51 is formed in the disc part 5 in the same number as the number of the injection pipe part 41 and the control pipe part 42. 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 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 penetrating injection holes 51. In this penetration state, the tip injection port 41c and the tip injection port 42c may be penetrated through the injection hole 51 by a small amount.

The front-end injection port 41c of the injection pipe part 41 is a structure which does not exceed the opening part 2a of the cylindrical housing part 2 [please refer to 1st figure (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 will not go beyond the opening 2a of the cylindrical housing portion 2 on the inner side, and will not protrude to the outside. Side of the situation. The injection hole 51 is formed as an elliptical through hole, or is formed to be a circle larger than the part of the tip injection port 41c and the tip injection port 42c that penetrates the injection hole 51, or it is not shown. It is also possible to form a cutout in a substantially U-shape with an open portion on the outer peripheral edge of the circular plate portion 5.

The fixed body A1 and the rotating body A2 in the air nozzle An of the present invention are assembled. Two bearings 34 are provided in the air nozzle An. First, in the fixed body A1, the first bearing 34 is inserted from the opening on the axially rear side of the fixed base 1, the spacer 35 is inserted second, and the second bearing 34 is inserted second.

Next, the rotating base 3 of the rotating body A2 is inserted into the inner peripheral side 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 penetrating portion 11b of the fixed cylindrical portion 11 of the fixed body A1, and the other is installed along the rotating body A2 is mounted on the cylindrical side surface part 31a of the cylindrical rotating part 3 (please refer to Figure 1).

In addition, the connecting fixing flange portion 12 is fixed to the rear end of the fixing base 1 of the fixed body A1 with a fixing tool 13 such as screws, 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, at the fixing through hole 12a of the fixing flange portion 12 for connection, the rotating flange portion 32 is fixed to the rear side end of the rotating cylindrical portion 31 of the rotating body A2 with a fixing tool 33 such as a screw. Thereby, the rotating body A2 is rotatably installed relative to the fixed body A1, and the rotating body A2 is rotated with the axis L as the rotation center line (please 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 inside (please refer to Figs. 1 and 3). The container part 36 is formed in a substantially doughnut or life ring shape, and has a hollow space 36b inside. The container portion 36 is fixed to the rotating base 3 of the rotating body A2 and is provided at a position close to the closing plate portion 22 of the cylindrical housing portion 2 of the fixed body A1.

The container part 36 rotates together with the rotating body A2. In the container portion 36, an annular insertion through hole 36a is formed on the surface close to the side of the closing plate portion 22 of the cylindrical housing portion 2, which serves as a shaft for fixing the cylindrical portion 11 of the fixed body A1. The structure is inserted into the insertion through hole 36a toward the tip portion on the opening side (please refer to Fig. 1). It is provided between the inner periphery of the insertion through hole 36a of the container part 36 and the outer periphery of the fixed cylindrical part 11 of the fixed base part 1 so that a gap may be created, and they are mutually non-contact. A bearing 34 provided between the fixed body A1 and the rotating body A2 is arranged 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 fixed body A1 and the rotating body A2, there is provided a structure surrounded by the container portion 36 and having an annular gap portion 36b (please refer to Fig. 1 , Figure 3). In addition, grease leaking from the bearing 34, lubricating oil, etc., and dripping from between the fixed body A1 and the rotating body A2 can be accumulated in the cavity 36b of the container portion 36.

That is, the container portion 36 is a storage container for storing the leaked grease or lubricating oil. Thereby, it can be implemented that the oil stain of grease does not diffuse into the cylindrical housing part 2, and it can prevent that the product 9 is soiled during 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 the excessive increase in the number of rotations (rotation speed) will be described. The air nozzle An can be used to rotate the rotating body A2 by adjusting the inclination angle (injection angle) θf of the jet port 41c from the tip end of the jet pipe portion 41 of the rotating body A2 with respect to the axis L of the air jet. Propulsion Ff. The sinθf has changed [please refer to Figure 5(A)]. That is, if it is set to reduce the inclination angle θf with respect to the axis line L, the rotational propulsion force Ff for rotating the rotating body A2. The sinθf will become smaller, so the rotation speed of the rotating body A2 will become smaller and slower, and the number of rotations (rotation speed) will also decrease, which can make the rotation speed of the rotating body A2 slower. However, the dry spray force Ff. cosθf will become larger and the drying force will increase.

In addition, if the inclination angle θf is set to be larger with respect to the axis line L, the rotational propulsion force Ff. sinθf will become larger. In this way, the rotation speed of the rotating body A2 will become larger and faster, and the number of rotations (rotation speed) will also increase, so that the rotation speed of the rotating body A2 can be accelerated. However, the dry spray force Ff. cosθf will become smaller and the drying force will be reduced.

Generally speaking, a common air nozzle An for drying operations has a smooth rotation performance because the rotating part provided with an air injection pipe is supported by a bearing, so that the rotating speed of the above-mentioned rotating part can be easily increased. Particularly, in a high rotation number region after the rotation speed is excessively increased, there is a problem of deterioration in drying quality or drying efficiency. That is, between the number of rotations of the rotating part of the air nozzle An and the drying quality, the number of rotations at the rotation speed reaches its optimal value. Although the drying efficiency or drying quality can be gradually improved, if the rotation speed is lower If the number of rotations exceeds the optimal value and continues to rise, it will become difficult to blow off the droplets efficiently (please refer to Figure 11).

That is, until the number of rotations reaches the optimal value, the compressed air can be blown to the workpiece in a pulsating manner (periodically, intermittently), so the droplets can be blown off efficiently. However, if the rotation speed increases excessively and the number of rotations exceeds the optimum value, the interval between the compressed air blown out in a wave-like manner gradually becomes shorter, and after a while, the compressed air cannot be waved. In this case, since compressed air is sprayed continuously, the drying quality and efficiency of the drying operation are reduced. In addition, if the number of revolutions of the undulating nozzle becomes higher, the life of the bearing will be shortened, and there will also be a problem of increased noise.

In the present invention, it is possible to prevent the rotation speed of the rotating body A2 in the air nozzle An from increasing excessively. As described above, the efficiency of the drying operation of the manufactured article 9 with the sprayed air of the air nozzle An is deteriorated and the drying operation cannot be performed smoothly. The state of the drying operation can also prevent the bearing or other components from being burdened due to the excessive increase in the rotation speed of the rotating body A2.

That is, there are appropriate numerical values for the rotation speed and the number of rotations of the rotating body A2. In addition, it is also preferable to adjust the rotation speed of the rotating body A2 to an optimal 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 in the number of rotations (rotation speed) of the rotating body A2 to prevent an excessive number of rotations ( Rotation speed), so the number of rotations (rotation speed) of the rotating body A2 can always be maintained in an optimal state.

Thereby, the ejected air ejected from the ejection outlet 41 at the front end of the ejection pipe portion 41 can be sprayed on the product 9 in a wave form (periodical, intermittent), and droplets can be blown off efficiently. The effect of blowing off the liquid (cleaning liquid, etc.), dust, oil, etc. attached to the product 9 and the effect of the drying operation can be optimized.

The suppression of the increase in the number of rotations (rotation speed) by the control pipe section 42 will be described below. Here, in the rotating body A2, two injection pipe portions 41 and two control pipe portions 42 are respectively provided. The two injection pipe portions 41 and the two control pipe portions 42 form a substantially cross shape, and the injection pipe portion 41 Those having the same shape and the same inner diameter as the control tube portion 42 will be set and described.

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

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

In addition, the rotational propulsive force Ff generated by the jet pipe portion 41. sinθf, and the rotation control force Fr generated by the control tube 42. sinθr is opposite to each other (reverse direction). Therefore, the rotation control force of the control tube portion 42 relative to the rotational propulsion force of the injection tube portion 41 can prevent the number of rotations (rotation speed) of the rotating body A2 from increasing excessively, and can reduce the number of rotations (rotation speed) of the rotating body A2. Always maintain the best condition. In addition, the control tube 42 has an adjustable inclination angle θr with respect to the axis L of the rotation base 3, and by changing the inclination angle θr, the desired number of rotations (rotation speed) of the rotating body A2 can be set.

The above description is applied to the condition that two injection pipe portions 41 and control pipe portions 42 each having the same shape are provided in the rotating body A2. Therefore, as shown in Figure 7, when two injection pipe portions 41 and one control pipe portion 42 are provided in the rotating body A2, the number of rotations (rotation speed) suppression structure is different, so it can be adapted to each situation. In this case, the inclination angle θr of the control tube 42 must be appropriately changed.

That is, with respect to the rotational propulsion force Ff generated by the two injection pipe portions 41. There are two sinθf, and the rotation control force Fr generated by one control tube 42. The number of 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 tube portion 42. The value of sinθr is adjusted to be larger, which also increases the inclination angle θr relative to the axis L. In addition, when the air nozzle An is used to dry the product 9, although the spray pipe section 41 plays its role, the spray air generated by the control pipe section 42 can also participate in the drying work.

In addition, Fig. 8 shows a case where the inclination angle θr of the control tube portion 42 with respect to the axial center line L is set to 0 degrees. In other words, the air injection direction from the injection port 42c at the front end of the control tube 42 coincides with the axis L. In this case, almost all of the spray air sprayed from the control pipe 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 as the drying target is large.

As the manufactured product 9 in this case, for example, a deep-bottomed container (polymerized plastic tube, pot-shaped one). In addition, when the inclination angle θr of the control tube portion 42 is set to 0 degrees with respect to the axis line L, since the jet air ejected from the control tube portion 42 is along the axis center line L, it is blown against by the full jet force. In the product 9, the reaction force at this time acts as the control force formed by the control tube portion 42, so that the excessive increase in the number of rotations (rotation speed) of the rotating body A2 can be suppressed, and the rotating body A2 can be maintained at The optimal number of rotations (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 (please refer to Fig. 9). Specifically, a plurality of air nozzles An are installed on the air nozzle base 6 and used. Furthermore, the air nozzle unit is assembled in the frame 7 of the air jet drying system (please refer to Fig. 10). The frame 7 of the air jet drying system has a blower 8 attached thereto. The air blowing section 8 is a manufacturer of compressed air such as an electric air compressor for supplying compressed air from the air blowing section 8 to the air nozzle An mounted on the air nozzle base 6 via the air nozzle base 6 (Please refer to Figure 9).

The air nozzle base 6 is provided with a base body 61, an air inlet 62, an air supply port 63, an air chamber 64, and a mounting portion 65 (please refer to Fig. 9). The base body 61 is formed in a substantially box shape, and has an air chamber 64 in which compressed air flows. The air nozzle unit composed of a plurality of air nozzles An and the air nozzle base 6 is installed at a predetermined position of the frame 7 of the air jet drying system with the mounting portion 65 of the air nozzle base 6 interposed therebetween.

The base body 61 is a fixing tool that clamps bolts, nuts, etc., and is installed in the drying operation area. The base body 61 is provided with a flat installation surface 61a for connecting and installing the air nozzle An. On the installation surface 61a, one or two or more air supply ports 63 are provided [please refer to Fig. 9 (B)]. In addition, the back surface 61b of the base body 61 has an air inlet 62 through which compressed air flows.

In addition, the air blower 8 causes the compressed air to flow from the air inlet 62 of the base body 61 into the air chamber 64. Furthermore, the compressed air flows from the air chamber 64 into the air supply port 63, and then from the air nozzle An of the rotating body A2 The air inlet 31d flows into the air flow path 31s. Furthermore, the compressed air in the air flow path 31s flows into the injection pipe portion 41, and the air is ejected obliquely with respect to the axis line L from the front end injection port 41c, and the rotating body A2 automatically rotates. As the rotating body A2 continues to automatically rotate, the air (gas) ejected from the injection pipe section 41 can blow off the water, oil, dust, etc., of the cleaning liquid attached to the product 9 .

The air jet drying system is equipped with a conveying part 71 in the frame 7. The conveying section 71 is composed of a conveying driving section 71a and a conveying table; the conveying driving section 71a is arranged from the conveying entrance side of the frame 7 in a direction toward the conveying exit side; the conveying table 71b is used by the conveying The driving unit 71a performs a movement operation. The conveyance driving unit 71a is, for example, a conveyor or the like, and is electrically driven by a motor or the like. When the conveyance inlet side of the air jet drying system is viewed from the front, the air nozzle unit is installed so as to surround the vertical direction and the lateral (width) direction of the conveyance section 71.

In addition, the air nozzle unit located above the conveying unit 71 can be adjusted in position in the vertical direction, and the air nozzle units installed on the left and right sides of the conveying unit 71 can be spaced in the left-right direction. When the air jet drying system blows off the water, oil, or dust, such as the washing liquid attached to the product 9, to dry the product 9 (also referred to as washing), It is moved by the conveying part 71 installed in the frame 7 of the air jet drying system.

When the product 9 placed on the conveying table 71b of the conveying section 71 is conveyed to the installation location of the air nozzle unit, it is installed on the upper side, lower side, left side, and right side of the conveying section 71 there. The place where the air nozzle unit on the side is installed is used as a drying operation area. When the conveying table 71b on which the product 9 is placed passes through the drying operation area, sprays from the air nozzles An on the upper, lower, left, and right sides are used. The air blows off the cleaning liquid adhering to the product 9 and the dust, dust, or oil that did not fall clean in the previous process, and the product 9 is dried. Furthermore, depending on the situation, washing and drying may be performed together.

In addition, in the air nozzle An, when the rotating body A2 is operating, the cavity S formed by the opening 2a of the cylindrical housing portion 2 and the disc portion 5 can be ejected from the tip end of the ejection pipe portion 41c. The flow of the ejected air (gas) becomes a turbulent state. Furthermore, the air ejected from the ejection pipe portion 41 in the void space S is mixed with the aforementioned turbulent air (gas) flow, thereby generating a more active and complex air flow, which can be blown extremely efficiently. Dust such as liquids, oils, dusts, etc. adhering to the product 9 is removed, and cleaning is performed by drying.
