Description

The present invention blows off residual liquid or adhering chips, dust, oil stains, etc. from a product manufactured in the manufacturing process or completed by cleaning with a cleaning liquid by the pressure of air injection to remove the surface of the product. Regarding the air injection drying system to be cleaned.

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

Further, in the machine parts manufacturing industry, chips, dust, residual cutting oil, mold release agent, etc. adhering to the surface of the product in the manufacturing process of the machine parts are cleaned with a cleaning liquid and then used with an air gun. It is generally blown off to remove it, or blown off with an air gun without cleaning with a cleaning liquid.

Here, as a product that requires a cleaning process with a cleaning solution and a subsequent drying process, specifically, a resin molded product, a tray for storing food, clothing, mechanical parts, etc., an HDD case, and the HDD case. There are trays, etc. for storing, and there are other resin molded products, machined products, etc. As a specific example of the tray, there is a resin container for storing a lunch box sold at a convenience store or a supermarket. In addition, as a tray, there is a container for protecting the semiconductor chip in the process of shipping the semiconductor chip, and such a tray may also be washed with a hot shower, and such a tray is subject to the drying work process. ..

Then, in the machine manufacturing industry, at the production site, oil stains, chips, and debris of the above-mentioned products are cleaned by spraying a cleaning liquid, and then water is blown off by air to perform such cleaning and drying.

In a conventional cleaning device, for example, there is an air gun or the like. After cleaning with a cleaning solution or the like to remove chips, dust, or residual cutting oil and other residues from products with uneven surfaces such as trays, the water remaining on most of the surface is dried by the above-mentioned air gun. It was possible. However, it has been difficult to almost completely drain the cleaning liquid remaining in the recessed portion of the uneven surface of the product.

Therefore, in order to drain the cleaning liquid almost completely, the product is placed upright and transported so that the cleaning liquid naturally falls downward and flows out from the product, or air is blown for a long time. Alternatively, various measures have been taken, such as raising the temperature of the air. However, these operations are extremely inefficient and the cleaning process of the product will take a considerable amount of time. Moreover, since many workers are required for such cleaning and drying means and a large amount of related equipment such as a compressor is required, the equipment must be expanded, which is large in terms of automation and cost. It will be a burden. Although the above-mentioned problems can be solved by the above-mentioned Patent Document 1, the liquid and dust remaining not only on the surface of the product but also in the recessed parts such as grooves and holes are positively scraped out to easily complete the draining. It cannot be said that it can be done, and further development is required.

Further, like the rotary wave nozzle in Patent Document 2, the injection portion is rotated together with the rotating body by the injection force due to the air injection from the nozzle, and the wave-like or intermittent air injection is applied in the drying operation after cleaning. Those that blow off water such as cleaning liquid have been developed. Then, in this type of thing, the rotation speed of the rotating body increases excessively, and the wave nature or intermittent effect of the air injection deteriorates from around a certain rotation speed, resulting in continuous air injection, and drying work. A phenomenon in which performance deteriorates may occur.

Patent Document 2 is provided with a rotation speed suppressing means for suppressing such an excessive increase in the rotation speed (rotation speed) of the rotating body. However, the rotation speed suppressing means in Patent Document 2 has a complicated structure, which may make it difficult and expensive to manufacture. Therefore, an object of the present invention (a technical problem to be solved) is to positively scrape out not only the surface of the component but also the water remaining in the recessed portion, and drain the adhering liquid or the adhering oil and the oil mixed with dust. Provided is an air injection drying system with an extremely simple configuration as a means for easily blowing off dirt, efficiently blowing off dust such as chips, and suppressing an excessive increase in the number of revolutions.

In the invention of claim 3, the air nozzle of the air nozzle unit has a configuration in which the inclination angle of the tip portion of the injection pipe portion can be changed by rotating the disk portion with respect to the rotation base portion. It is extremely easy to adjust the rotation speed of the rotating body of the air nozzle and the air injection from the air nozzle by rotating the disk portion clockwise or counterclockwise by an appropriate amount. In particular, if the rotation speed of the rotating body in the air nozzle of each air nozzle unit is excessively increased, the efficiency of the drying operation for the product by the air injection of the air nozzle may be deteriorated and may not be successful. Even in such a case, the inclination angle of the tip of the injection pipe portion is appropriately changed to prevent the rotation speed of the rotation base portion from increasing excessively, and the rotation base portion maintains an appropriate rotation speed.

Since the scale portion is provided on the scale plate fixed to the rotation base portion and the index portion is provided on the disk portion, it is extremely easy to confirm the adjustment result of the inclination angle of the tip portion of the injection pipe portion.

In the invention of claim 7, the injection pipe portion is provided with a throttle portion for reducing the cross-sectional area of the pipe, and in the invention of claim 8, air is injected in the direction opposite to the injection pipe portion and the inner diameter is reduced. By providing a restraining pipe portion and providing a throttle portion for changing the cross-sectional area of the pipe, the injection force of air injection from the injection pipe portion can be adjusted, and the rotating main body of the air nozzle can be adjusted. The rotation speed can be adjusted to prevent the rotation speed from increasing excessively and to maintain the best rotation speed.

It is configured (see FIGS. 1 and 2).

First, the upper air nozzle unit Aa, the lower air nozzle unit Ab, the left air nozzle unit Ac, and the right air nozzle unit Ad will be described [see FIGS. 2 (B) and 2 (C)]. These air nozzle units have substantially the same configuration, and are composed of an air nozzle An and an air nozzle base 6. That is, a unit in which a plurality of air nozzles An are mounted on the air nozzle base 6 is referred to as an air nozzle unit [see FIGS. 1 to 4, 6 (A), 9 (A), etc.].

It is preferable that the air is injected from all of the Ad at substantially the same time.

The region where the upper air nozzle unit Aa, the lower air nozzle unit Ab, the left air nozzle unit Ac, and the right air nozzle unit Ad are concentrated in the frame body 7 is referred to as a drying work region 7s. Within the frame body 7, there is one drying work area 7s (see FIGS. 1 and 2). In addition, there is also an embodiment in which a plurality of two or more drying work areas 7s are provided in the frame body 7 [see FIGS. 13A and 13B].

The upper air nozzle unit Aa, the lower air nozzle unit Ab, the left air nozzle unit Ac, and the right air nozzle unit Ad each have an air nozzle An. The air nozzle An serves to inject compressed air in the drying operation of the product 9. The air nozzle An mainly includes a fixed main body A1 and a rotating main body A2 (FIG. 5).

The fixed main body A1 is a non-rotating structure, and the rotating main body A2 is attached to the fixed main body A1 so as to be rotatable with respect to the fixed main body A1 (FIGS. 6 and 6). Figure 9,
(See FIG. 11). In the present invention, the gas of the air injected from the air nozzle An is mainly ordinary air, but various kinds of gases are also included. In addition, the wording "air" in the following description may be replaced with gas.

The fixed main body A1 is mainly composed of a fixed base portion 1 and a cylindrical housing portion 2 [
See FIG. 2 (A)]. Here, in the present invention, the air nozzle An has an "opening side" and a "rear side" in the axial direction. Further, the opening side may be referred to as a front side. The axial direction refers to the direction of the shaft core that is the center of rotation when the rotating body A2 rotates. The shaft core wire that is the center of rotation is referred to as the shaft core wire L of the rotating body A2. This shaft core wire L is also applied to the rotation base portion 3 and the disk portion 5 constituting the rotation body A2. The shaft core wire L is shown in the main drawing.

The fixed main body A1 and the rotating main body A2 constituting the air nozzle An have the opening side (front side) and the rotating main body A2 in a state where the rotating main body A2 is incorporated in the fixed main body A1 and their respective shaft cores coincide with the shaft core wire L. The position on the rear side is determined. The shaft core wire L is also applied to the shaft core of the fixed main body A1. That is, with the rotating main body A2 attached to the fixed main body A1, the centers of the rotating main bodies A2 coincide with or substantially coincide with the shaft core wire L [see FIGS. 6 (A), 9 (A), and 11].

The fixed base portion 1 has a fixed cylindrical portion 11 and a connecting fixed flange portion 12. The fixed cylindrical portion 11 is formed in a substantially hollow cylindrical shape [see FIGS. 6 (A), 9 (A), 11 (A), (C), etc.], and is a cylinder of the rotating main body A2 described later. The rotating portion 3 is mounted so as to be rotatable with the shaft core wire L as the axis of rotation. As described above, the fixed cylindrical portion 11 has a substantially hollow cylindrical shape, and has a cylindrical penetrating portion 11b having both sides open in the axial direction along the axial core line L in the cylindrical shape. Screw holes 11c on which internal screws are formed are formed at equal intervals along the peripheral edge of the opening of the rear end of the fixed cylindrical portion 11.

The connection fixed flange portion 12 serves as a lid when the bearing 34 and the spacer 35 mounted between the fixed cylindrical portion 11 and the rotating main body A2 are housed and arranged, and the air nozzle is attached to the air nozzle base 6 described later. It serves as a connecting member for mounting the An [see FIGS. 6 (A), 9 (A), etc.]. The connection fixing flange portion 12 is fixed to one end of the fixed cylindrical portion 11 in the axial direction by a plurality of fixing tools 13 such as screws. The connection fixed flange portion 12 is formed in an annular disk shape and is larger than the outer diameter dimension of the fixed cylindrical portion 11. The connection fixing flange portion 12 is formed with a fixing through hole 12a, a connection hole 12b, and a connection hole 12c. The connection between the fixed cylindrical portion 11 and the connecting fixed flange portion 12 is performed by the fixing tool 13, the connecting hole 12b, and the screw hole 11c.

The cylindrical housing portion 2 has a diameter larger than that of the fixed cylindrical portion 11 of the fixed base portion 1 and has a cylindrical container shape [FIGS. 5 (A) and 6 (A)). , Fig. 9 (A), Fig. 11 etc.]. The cylindrical housing portion 2 has a cylindrical side wall plate portion 21 and a closing plate portion 22, and an opening 2a is provided on one end side in the axial direction and on the opposite side to the closing plate portion 22. Then, as described above, the opening side of the cylindrical housing portion 2 of the fixed main body A1 is the opening side (front side), and the opposite side in the axial direction along the shaft core wire L is the rear side.

A through hole 22a into which one end of the fixed cylindrical portion 11 of the fixed base portion 1 in the axial direction is inserted is formed on the closing plate portion 22 side of the cylindrical housing portion 2, and the fixed cylindrical portion 11 and the cylindrical housing portion 2 are formed. The closing plate portion 22 is fixed by a fixing means such as welding. At this time, a part of the fixed cylindrical portion 11 on one end side in the axial direction is in a state of biting into the closing plate portion 22 of the cylindrical housing portion 2.

That is, a part of one end of the fixed cylindrical portion 11 in the axial direction is inserted into the cylindrical housing portion 2 [see FIGS. 6 (A), 9 (A), etc.]. Therefore, the outer peripheral side surface of the fixed cylindrical portion 11 closer to the opening side (front side) in the axial direction is a small diameter portion having a smaller diameter, and there is a step portion 11a which is a step thereof. The step portion 11a serves as a stopper and alignment for inserting and connecting the small diameter portion of the fixed cylindrical portion 11 into the through hole 22a of the closing plate portion 22 of the cylindrical housing portion 2.

Next, the rotating main body A2 has a rotating base portion 3, an injection pipe portion 4, and a disk portion 5 (see FIGS. 6 to 11). The rotation base portion 3 is composed of a rotation cylinder portion 31 and a rotation flange portion 32 [see FIGS. 6 (A), (B), 9 (A), 11 (A), (C), etc.]. The rotating cylindrical portion 31 is formed in a cylindrical cup shape, and is composed of a cylindrical side surface portion 31a and a tip surface portion 31b. The cylindrical side surface portion 31a constitutes the outer circumference of the rotating cylindrical portion 31, and the tip surface portion 31b is a portion that closes the axial opening side (front side) of the rotating cylindrical portion 31. Inside the rotating cylindrical portion 31, an air flow path 31s having a cylindrical void is formed.

The rear side of the rotating cylindrical portion 31 is an open air inlet 31d. An air discharge portion 31c having a through hole penetrating between the inside and the outside is formed at or near the tip surface portion 31b side of the rotating cylinder portion 31. The air discharge portion 31c is a portion where the root portion 4j of the injection pipe portion 4, which will be described later, is inserted and the inside of the injection pipe portion 4 and the air flow path 31s are communicated with each other. A rotary flange portion 32 is fixed to the rear side of the rotary cylinder portion 31 in the axial direction by a fixing tool 33 such as a screw [see FIGS. 6 (A), 6 (B), 9 (A)]. The rotating flange portion 32 rotatably locks to the connecting fixed flange portion 12 of the fixed main body A1 when mounted on the fixed main body A1 so that the rotating main body A2 can rotate in a stable state. Make up.

The rotary flange portion 32 has an annular disc shape, an air inlet hole 32a is formed, and a connection hole 32b is formed on the peripheral edge of the air inlet hole 32a. A screw hole 31e is formed on the end surface of the rotary cylinder portion 31 on the rear side in the axial direction, and the rotary flange portion 32 is fixed to the rotary cylinder portion 31 by a connection hole 32b, a screw hole 31e, and a fixing tool 33 [FIG. 6 (FIG. 6). See A), (B), FIG. 9 (A)]. The outer peripheral edge of the rotating flange portion 32 can be rotatably locked to the inner peripheral edge of the fixing through hole 12a of the fixing flange portion 12 for connecting the fixing main body A1 [FIGS. 6 (A) and 9 (FIG. 6) and 9 (FIG. 9). A), see FIGS. 11 (A) and 11 (C)].

The injection pipe portion 4 is mounted on the rotating cylindrical portion 31 at least one or two. The injection pipe portion 4 is a pipe member that circulates air to generate injection air for cleaning and injection air for propulsion that is a rotational force for rotating the rotating main body A2. The root portion 4j, which is one end of the injection pipe portion 4, is fixed to the air discharge portion 31c of the rotating cylindrical portion 31 by a fixing means such as press fitting and tightening with screws or the like. The vicinity of the tip ejection port 41 of the injection pipe portion 4 is inclined at a predetermined angle θ with respect to the axis core line L of the rotation base portion 3 in the direction opposite to the direction in which the rotation body A2 rotates in the set rotation direction. [See FIG. 6 (A)].

The rotation direction of the rotating main body A2 is set to be either clockwise or counterclockwise when viewed from the opening side (front side) of the air nozzle An. Then, assuming that the air injection force of the air injected from the tip ejection port 41 is F, the direction of F is an inclination of an angle θ with respect to the shaft core wire L of the air nozzle An. Therefore, the cleaning force, which is the jetting force for cleaning, is Fcosθ. Further, the propulsive force for rotating the rotating body A2 is Fsinθ [see FIG. 6 (A)]. In this way, the rotating body A2 of the air nozzle An is rotated by the propulsive force Fsinθ for rotating, which is a component force generated from the air injection force F injected from the tip ejection port 41 of the injection pipe portion 4. can do.

The inclination angle θ is set in a predetermined range, and specifically, is within the range of the minimum angle and the maximum angle. The minimum angle is about 10 degrees and the maximum angle is about 30 degrees.

Then, the disc portion 5 is connected to the tip surface portion 31b of the rotating cylinder portion 31 of the rotating base portion 3 so that the rotation centers of the disc portion 5 and the rotating base portion 3 coincide with or substantially coincide with each other. At this time, a cylindrical collar portion 53 is provided between the tip surface portion 31b and the disk portion 5 in order to provide a predetermined distance, and the tip surface portion 31b, the disk portion 5, and the collar portion 53 are screwed together.

The vicinity of the injection hole 51 refers to the vicinity of the injection hole 51, including both sides of the disk 5, that is, both the opening side and the rear side of the disk 5. Specifically, the tip ejection port 41 of the injection pipe portion 4 penetrates the injection hole portion 51. Further, only a part of the tip ejection port 41 of the injection pipe portion 4 may penetrate the injection hole portion 51. Further, although not particularly shown, there is a case where the tip ejection port 41 of the injection pipe portion 4 does not penetrate the injection hole portion 51 but is close to the injection hole portion 51.

The injection hole 51 may be a circular or elliptical through hole, or, although not particularly shown, a substantially U-shaped notch having an open portion at the outer peripheral edge of the disk portion 5. .. The outer peripheral edge 5a of the disk portion 5 has a configuration close to the inner circumference of the cylindrical housing portion 2.

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

Next, the rotation base portion 3 of the rotation 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 mounted along the inner peripheral side of the cylindrical penetrating portion 11b of the fixed cylindrical portion 11 of the fixed main body A1, and the other one is rotated. Body A2
It is mounted along the cylindrical side surface portion 31a of the cylindrical rotating portion 3 of the above [see FIGS. 6 (A), 9 (A), etc.].

Then, the connection fixing flange portion 12 is fixed to the rear end portion of the fixing base portion 1 of the fixing main body A1 by a fixing tool 13 such as a screw, and the first and second bearings 34 and the spacer 35 are fixed to the fixing main body A1.

Further, the rotating flange portion 32 is fixed to the rear end of the rotating cylindrical portion 31 of the rotating main body A2 at the fixed through hole 12a of the connecting fixed flange portion 12 by a fixing tool 33 such as a screw. As a result, the rotating main body A2 is rotatably attached to the fixed main body A1, and the rotating main body A2 is attached to the shaft core wire L.
Is rotated as the center line of rotation.

The rotating body A2 of the upper air nozzle unit Aa has an embodiment in which a flat cylindrical container portion 36 having a gap portion 36b provided therein is provided [FIGS. 5 (A), 6 (A), and FIG. 9. See FIGS. 11 (A), 11 (C), etc.]. The container portion 36 is formed in a substantially donut or floating ring shape, and has a hollow void portion 36b inside. The container portion 36 is fixed to the rotation base portion 3 of the rotating main body A2 and is installed at a position closer to the closing plate portion 22 side of the cylindrical housing portion 2 of the fixed main body A1.

The container portion 36 rotates together with the rotating main body A2. The container portion 36 has a cylindrical housing portion 2
An annular insertion through hole 36a is formed on the surface of the fixed body A1 close to the closing plate portion 22 side, and the tip portion of the fixed cylindrical portion 11 of the fixed main body A1 on the axial opening side is inserted into the insertion through hole 36a. [See FIGS. 6 (A) and 6 (D)].

A gap is formed between the inner peripheral edge of the insertion through hole 36a of the container portion 36 and the outer peripheral edge of the fixed cylindrical portion 11 of the fixed base portion 1, and is not in contact with each other. A bearing 34 provided between the fixed main body A1 and the rotating main body A2 is arranged at the tip portion of the fixed cylindrical portion 11 on the axial opening side.

That is, the circumference of the position where the bearing 34 mounted between the fixed main body A1 and the rotating main body A2 is located is surrounded by the container portion 36, and the annular gap portion 36b exists [FIG. 5]. (A), FIG. 6 (A), FIG. 9, FIG. 11 (A), (C), etc.]. Then, the grease of the bearing 34, the lubricating oil, or the like leaks out, and the oil dripping from between the fixed main body A1 and the rotating main body A2 can be stored in the gap portion 6b of the container portion 36 [FIG. 6 (FIG. 6). See D)]. That is, the container portion 36 is a storage container for the leaked grease or lubricating oil. As a result, dirt of oil can be prevented from diffusing into the cylindrical housing portion 2, and it is possible to prevent the product 9 from being soiled during the drying operation of the product 9.

The container portion 36 may be attached only to the air nozzle An of the upper air nozzle unit Aa, and the container portion 36 is attached to each of the other lower air nozzle unit Ab, the left air nozzle unit Ac, and the right air nozzle unit Ad. Does not have to be installed. However, the container portion 36 may be mounted on all the air nozzles An in the lower air nozzle unit Ab, the left air nozzle unit Ac, and the right air nozzle unit Ad.

The air nozzles An of the upper air nozzle unit Aa, the lower air nozzle unit Ab, the left air nozzle unit Ac, and the right air nozzle unit Ad are provided with the tip injection outlet 41 at the tip of the injection pipe portion 4 by rotating the disk portion 5. There is an embodiment in which the inclination angle θ with respect to the axis core wire L of the above can be changed. There are a plurality of this embodiment.

First, a first embodiment will be described in which the inclination angle θ with respect to the shaft core wire L of the tip injection outlet 41 at the tip of the injection pipe portion 4 can be changed. The rotating cylindrical portion 31 of the rotating base portion 3 is divided into upper and lower parts of the cylinder main body portion 3A and the cylinder bottom portion 3B, and both are joined by a fixing tool 37 such as a screw [FIGS. 6 (B) and 6 (C)). reference〕. The air discharge portion 31c is divided by a cylinder body 3A and a cylinder bottom 3B [see FIGS. 6 (B) and 6 (C)]. The air discharge portion 31c on the cylinder body 3A side and the air discharge portion 31c on the cylinder bottom 3B side each have a half-circle shape.

The root portion 4j of the injection pipe portion 4 is arranged at the air discharge portion 31c on either side of the cylinder body 3A or the cylinder bottom 3B, the cylinder body 3A and the cylinder bottom 3B are joined, and the cylinder body 3A and the cylinder bottom 3B are joined. Is fixed by a fixing tool 37 such as a screw or a bolt. The fixing force of the fixing tool 37 at this time tightens the root portion 4j of the injection pipe portion 4 and firmly fixes it to the air discharging portion 31c. Then, by loosening the fixing tool 37, the cylinder body 3A and the cylinder bottom portion 3B are slightly separated from each other, the air discharge portion 31c is slightly expanded, and the injection pipe portion 4 is released from the tightening at the root portion 4j.

The tip ejection port 41 of the bent portion 4b of the injection pipe portion 4 is configured to insert the injection hole portion 51 of the disc portion 5 in a penetrating state. The injection hole portion 51 is formed in an elongated hole shape along the diameter direction of the disk portion 5. Further, the disk portion 5 can freely rotate in either the clockwise direction or the counterclockwise direction by loosening the fastener 54 with respect to the rotating cylindrical portion 31 or the collar portion 53 mounted on the rotating cylindrical portion 31. I will leave it as.

Then, by loosening the tightening of the fixing tool 37 and the fixing tool 54 and rotating the disk portion 5 clockwise or counterclockwise, the injection hole portion 51 also moves together with the disk portion 5 and the injection hole is formed. The tip ejection port 41 of the injection pipe portion 4 which is inserted through the portion 51 is configured to move so as to be dragged by the injection hole portion 51 (see FIG. 7).

As a result, by rotating the disk portion 5, the injection pipe portion 4 is dragged by the injection hole portion 51 and rotates around the root portion 4j, and the injection pipe portion 4 is injected with respect to the shaft core wire L of the tip ejection port 41. The angle θ can be adjusted to the desired position. The change adjustment of the injection angle θ with respect to the shaft core wire L depends on the degree of the rotation angle of the disk portion 5. Then, the fixing tool 37 is tightened again to join and fix the cylinder body 3A and the cylinder bottom portion 3B, and then the fixing tool 54 is tightened to fix the disk portion 5 to the rotating cylindrical portion 31 and the tip of the injection pipe portion 4. The injection angle θ with respect to the axis L of the ejection port 41 is completed.

An operation through hole 58 is formed in the disk portion 5 (see FIGS. 5 and 7). The operation through hole 58 is used to tighten the fastener 37 while inserting a tool such as a screwdriver from the outside of the disk portion 5 in a state where the disk portion 5 is connected to the rotating cylindrical portion 31 of the rotation base portion 3. It is a through hole for releasing the tightening. The operation through hole 58 of the disk portion 5 is a position corresponding to the position of the fixing tool 37. The operation through hole 58 may be an elongated hole [see FIG. 5 (A)] along the circumferential direction of the disk portion 5, or may be a circular hole corresponding to each fastener 37.

Further, a modified example of the first embodiment in which the inclination angle θ with respect to the shaft core wire L of the tip injection outlet 41 at the tip of the injection pipe portion 4 can be changed will be described (see FIG. 8). In the modified example of the first embodiment, the rotating cylindrical portion 31 of the rotating base portion 3 is integrally formed, and the total air discharging portion 31c is also formed as one through hole [FIG. 8 (FIG. 8). A) See]. Then, the root portion 4j of the injection pipe portion 4 is inserted and mounted in the air discharge portion 31c so as to be rotatable in the circumferential direction with respect to the air discharge portion 31c. A lock screw hole 31f that penetrates the tip surface portion 31b of the rotating cylindrical portion 31 and the inner peripheral side of the air discharge portion 31c is formed, and the lock screw 38 is screwed [see FIG. 8B]. Here, the lock screw 37 is preferably a hexagon socket head cap screw.

One or two lock screw holes 31f are provided. When two lock screw holes 31f are provided, the opening position of each lock screw hole 31f on the tip surface portion 31b side extends from the center position of the air discharge portion 31c to both sides along the outer peripheral direction of the tip surface portion 31b. It is formed [see FIGS. 8 (C) and 8 (D)]. Then, both the lock screw holes 31f and 31f are inclined so as to be symmetrical or substantially symmetrical with respect to both the shaft core wire L and the air discharge portion 31c.

When only one lock screw hole 31f is provided, the lock screw hole 31f is set so as to face the air discharge portion 31c in the same direction as the shaft core wire L, although not particularly shown. Further, also in the modified example of the first embodiment, the disk portion 5 is formed with an operation through hole 58, and the disk portion 5 is connected to the rotating cylindrical portion 31 of the rotating base portion 3. Therefore, the lock screw 37 can be tightened and released while inserting a tool such as a screwdriver from the outside of the disk portion 5 [see FIG. 8 (B)].

The root portion 4j of the injection pipe portion 4 inserted into the air discharge portion 31c is tightened and released by the tip of the lock screw 38. By releasing the tightening of the lock screw 38, the root portion 4j of the injection pipe portion 4 becomes rotatable in the circumferential direction, and the inclination angle θ can be adjusted by rotating the disc portion 5 [FIG. 8 (D)). Reference], the injection pipe portion 4 can be fixed to the air discharge portion 31c of the rotating cylindrical portion 31 by tightening the lock screw 38 [see FIG. 8C].

Next, a second embodiment will be described in which the inclination angle θ with respect to the shaft core wire L of the tip injection outlet 41 at the tip of the injection pipe portion 4 is variable (see FIG. 9). In this second embodiment, the retaining ring 46 and the sealing material 47 are provided. The rotating cylindrical portion 31 of the rotating base portion 3 is a single unit [see FIG. 9 (A)]. The air discharge portion 31c of the rotary cylinder portion 31 and the root portion 4j of the injection pipe portion 4 are made rotatable with the root portion 4j of the injection pipe portion 4 inserted into the air discharge portion 31c. The injection pipe portion 4 and the root portion 4j have a smaller diameter than the other portions (linear portion 4a and bent portion 4b), and a stepped portion is formed [see FIG. 9 (D)]. Further, a groove portion 4c is formed in the root portion 4j along the circumferential direction [see FIG. 9 (D)].

Then, the root portion 4j of the injection pipe portion 4 is inserted into the air discharge portion 31c of the rotating cylinder portion 31, and the sealing material 47 is fitted into the portion of the root portion 4j that bites into the rotating cylinder portion 31, and then the groove portion is formed. It is fitted and mounted on 4c [see FIGS. 9B and 9C]. As a result, the injection pipe portion 4 can be made rotatable around the root portion 4j, and by rotating the disc portion 5, the injection pipe portion 4 is dragged by the injection hole portion 51. Therefore, the injection angle θ of the tip ejection port 41 with respect to the shaft core wire L can be adjusted to a desired position by rotating around the root portion 4j.

Regarding the disk portion 5, substantially the same as in the first embodiment described above, the fastener 54 is loosened with respect to the rotating cylindrical portion 31 or the collar portion 53 mounted on the rotating cylindrical portion 31 in the clockwise direction and in the clockwise direction. It should be configured so that it can rotate freely in any of the opposite directions. Specifically, an E washer is used for the retaining ring 46. Specifically, rubber, an oil seal, a gasket, or the like is used as the sealing material 47.

As described above, the air nozzle An has an inclination angle (injection angle) θ with respect to the shaft core line L of the tip portion of the injection pipe portion 4, that is, the tip injection outlet 41, by rotating the disk portion 5 with respect to the rotation base portion 3. By making the configuration variable, it is possible to adjust the increase / decrease in the rotation speed of the rotating main body A2 of the air nozzle An and the air injection from the injection pipe portion 4. The adjustment of the inclination angle θ with respect to the shaft core wire L of the injection pipe portion 4 can be made extremely easy by simply rotating the disc portion 5 clockwise or counterclockwise by an appropriate amount.

By adjusting the inclination angle (injection angle) θ of the injection pipe portion 4 with respect to the shaft core wire L, the propulsive force Fsin θ for rotating the rotating main body A2 changes. That is, if the inclination angle θ is set to be smaller with respect to the shaft core wire L, the propulsive force Fsin θ for rotation becomes smaller, the rotation speed of the rotation body A2 becomes smaller and slower, and the rotation speed (rpm) also becomes. Less. Further, if the inclination angle θ is set to be larger than that of the shaft core wire L, the propulsive force Fsin θ for rotation is increased, the rotation speed of the rotating main body A2 is increased and increased, and the rotation speed (rpm) is also increased. More.

Generally, in a normal air nozzle for drying work, a rotating portion provided with an air injection pipe is supported by a bearing and has smooth rotational performance, so that the rotational speed of the rotating portion increases. It is easy to do. In particular, there is a problem that the drying quality or the drying efficiency deteriorates in the high rotation speed range where the rotation speed is excessively increased. That is, between the rotation speed of the rotating portion of the air nozzle and the drying quality, the drying efficiency or the drying quality will improve until the rotation speed at the rotation speed reaches the optimum value, but the rotation speed at the rotation speed If it continues to rise above its optimum value, it becomes difficult to blow off the droplets efficiently.

That is, until the rotation speed reaches the optimum value, the compressed air can be blown onto the work in a wave shape (periodically or intermittently), and the droplets can be efficiently blown off. However, when the rotation speed increases excessively and the rotation speed exceeds the optimum value, the interval of the compressed air blown in a wave shape gradually becomes shorter, and eventually the compressed air does not generate a wave. Since this is equivalent to continuously injecting compressed air, the drying quality and the drying work efficiency are deteriorated. Further, when the rotation speed of the rotary wave nozzle is increased, there is a problem that the life of the bearing is shortened and the noise is also increased.

The above situation may also apply in the present invention. That is, as described above, the rotation speed of the rotating main body A2 in each air nozzle An of the upper air nozzle unit Aa, the lower air nozzle unit Ab, the left air nozzle unit Ac, and the right air nozzle unit Ad increases excessively, so that the air nozzle An There is a possibility that the efficiency of the drying operation for the product 9 by air injection is deteriorated, and the drying operation does not go well. Further, the excessive increase in the rotation speed of the rotating main body A2 may impose a burden on the bearing and other members.

That is, there are appropriate values for the rotation speed and the rotation speed of the rotation body A2. Further, it is preferable to adjust the rotation speed of the rotating main body A2 to obtain an optimum state depending on the shape and size of the product 9. In such a case, in the present invention, the tilt angle (injection angle) θ of the tip injection outlet 41 of the injection pipe portion 4 with respect to the shaft core wire L is appropriately changed and set so that the propulsive force Fsin θ becomes small. It suppresses the excessive increase in the rotation speed of A2 so that the optimum rotation speed can be maintained. The injected air from the tip injection outlet 41 of the injection pipe portion 4 can be made into a wave shape (periodic, intermittent) and sprayed onto the product 9, and the droplets can be efficiently blown off. The liquid (cleaning liquid, etc.) adhering to the product 9, dust, oil stains, etc. can be blown off, and the effect of the drying operation can be maximized.

Next, the scale wire portion 55b and the index portion 56 that enable the state of the inclination angle θ of the tip injection outlet 41 at the tip of the injection pipe portion 4 with respect to the axis core wire L to be confirmed from the outside of the disc portion 5 of the air nozzle An will be described. To do. This embodiment is attached to the embodiment in which the inclination angle θ with respect to the axis L of the tip injection outlet 41 at the tip of the injection pipe portion 4 can be changed by the rotation operation of the disk portion 5 described above. It is a configuration to do.

There are a plurality of embodiments of the scale line portion 55b and the index portion 56. In the first embodiment, the scale portion 55 is provided with the elongated hole-shaped confirmation window portion 55a and the scale line portion 55b on the disk portion 5, and the index portion 56 is provided on the rotating cylindrical portion 31 of the rotation base portion 3.

The elongated hole-shaped confirmation window portion 55a is an elongated hole formed along the circumferential direction of the disk portion 5 (see FIGS. 5 and 7). The scale line portion 55b is the elongated hole-shaped confirmation window portion 5 along the extending direction of the elongated hole-shaped confirmation window portion 55a.
It is provided at a position close to 5a. The scale line portion 55b is provided on the disk portion 5 by engraving or printing. A scale index pin 56a is fixed to the tip surface portion 31b of the rotating cylindrical portion 31 so that the tip portion thereof can be clearly seen in the elongated hole-shaped confirmation window portion 55a.

The conical tip portion of the scale index pin 56a has a configuration that slightly protrudes from the elongated hole-shaped confirmation window portion 55a to the outer side of the disc portion 5, or is located on the inner side of the disc portion 5 without protruding. It is a configuration to do. In any case, it is sufficient that the tip of the scale index pin 56a can be confirmed from the outside of the elongated hole-shaped confirmation window portion 55a (see FIGS. 5 and 7).

Then, when adjusting the inclination angle θ of the tip injection outlet 41 at the tip of the injection pipe portion 4 with respect to the shaft core wire L, the fixing tool 54 (fixing tool 37 if necessary) is loosened, and the disk portion 5 is rotated as a base. The elongated hole-shaped confirmation window portion 55a and the scale index pin 56a move relatively by rotating the disc portion 5 in a free state in which the portion 3 can rotate with respect to the rotating cylindrical portion 31. Substantially, the scale index pin 56a is on the fixed side, and the elongated hole-shaped confirmation window portion 55a is on the rotational movement side.

In the scale line portion 55b, a numerical value corresponding to an inclination angle θ with respect to the axis core wire L of the tip ejection port 41 of the injection pipe portion 4 is described (see FIGS. 5 and 7). The numerical value of the scale line portion 55b is, for example, 0 to 30 degrees. Then, by rotating the disk portion 5, the elongated hole-shaped confirmation window portion 55a (
(Including the scale line portion 55b) and the scale index pin 56a move relatively, and the scale index pin 56
Depending on the corresponding positions of a and the scale line portion 55b, the inclination angle θ of the tip injection outlet 41 at the tip of the injection pipe portion 4 with respect to the shaft core wire L can be visually confirmed (see FIG. 7).

FIG. 7A is an enlarged view of the scale portion 55 and the index portion 56 at that time when the inclination angle θ of the injection pipe portion 4 is in a normal state. FIG. 7C is an enlarged view of the scale portion 55 and the index portion 56 at that time when the inclination angle θ of the injection pipe portion 4 is maximum, and FIG. 7D is an enlarged view of the scale portion 55 and the index portion 56 at that time. FIG. 7 (E) is an enlarged view of the scale portion 55 and the index portion 56 at that time when the inclination angle θ of the injection pipe portion 4 is the minimum.

Next, a second embodiment of the scale line portion 55b and the index portion 56 will be described. In this embodiment, the scale plate 57 is provided. A substantially rectangular fixing through hole 57a is formed at the center position of the scale plate 57. The scale plate 57 is provided with a scale line portion 55b of the scale portion 55 [FIG. 10 (Fig. 10).
See E) and (B)]. Further, the collar portion 53 is integrally formed with the rotating cylindrical portion 31 [see FIG. 10 (A)]. At the tip of the collar portion 53, a flat cylindrical cylindrical protrusion 53a and a square protrusion 53b that is concentric with the cylindrical protrusion 53a and smaller than the cylindrical protrusion 53a are integrally formed. [See FIGS. 10 (A) and 10 (C)].

The cylindrical protrusion 53a has the same thickness as the disk portion 5, and the square protrusion 53b has the same thickness as the scale plate 57. A screw hole for screwing with the fastener 54 is formed at the center of the protrusion 53a. Then, it is inserted into the mounting through hole 5n of the disk portion 5 into the cylindrical protrusion 53a of the collar portion 53 [see FIG. 10 (D)]. Further, the scale plate 57 is arranged on the disk portion 5, and the square protrusion 53b is inserted into the fixing through hole 57a [see FIG. 10 (E)]. Further, a presser washer 59 is arranged on the scale plate 57, and these are fixed by the fixing tool 54 [see FIG. 10 (A)]. The disk portion 5 is provided with an index portion 56. The index portion 56 is provided close to the scale line portion 55b of the scale plate 57 [see FIGS. 10 (B) and 10 (E)].

With the above configuration, by loosening the fixing tool 54 and releasing the tightening, the scale plate 57 is fixed to the collar portion 53, and the disk portion 5 is in a state where it can freely rotate with respect to the collar portion 53, and the injection is performed. The inclination angle θ with respect to the shaft core line L of the tip ejection port 41 of the pipe portion 4 can be adjusted. The surface of the scale plate 57 that comes into contact with the disk portion 5 is made uneven so as to cause friction, so that the disk portion 5 can be securely fixed to the collar portion 53 by tightening the fixing tool 54. Sometimes. Then, when confirming the inclination angle θ with respect to the shaft core wire L of the tip injection outlet 41 at the tip of the injection pipe portion 4, the position of the index portion 56 of the disk portion 5 with respect to the scale line portion 55b of the scale plate 57 is set. The state of the injection angle θ of the tip injection port 41 of the injection pipe portion 4 can be visually confirmed [see FIGS. 10 (B) and 10 (C)].

Further, there is an embodiment in which the injection pipe portion 4 is provided with a throttle portion 42 for reducing the cross-sectional area of the pipe [see FIG. 11 (A)]. The cross-sectional area of the throttle portion 42 is adjusted by the adjusting bolt 42a screwed into the injection pipe portion 4. Specifically, a through hole 4d is formed in the linear portion 4a of the injection pipe portion 4, and a bolt base portion 42b on which an internal screw is formed is mounted, and the bolt base portion 42b is a through hole portion of the linear portion 4a.

An adjustment bolt 42a is attached to the bolt base portion 42b, and by rotating the adjustment bolt 42a in the axial direction, the screw portion of the adjustment bolt 42a moves in and out of the linear portion 4a of the injection pipe portion 4. It can be adjusted so as to reduce the cross-sectional area of the injection pipe portion 4. As a result, the injection force of the air injection from the injection pipe portion 4 is adjusted. As a result, the air injection force from the injection pipe portion 4 can be adjusted by the tightening condition of the adjustment bolt 42a, and the optimum rotation speed of the rotation body A2 of the air nozzle An can be easily adjusted.
