Description

  The present invention relates to a drying apparatus and a drying method for drying a liquid attached to a component having a hole formed in a main body.

For example, as shown in FIG. 9, a plurality of holes 931 are formed in a part 93 used for an injection nozzle such as an injector.
And since the chip | tip which generate | occur | produces when forming the hole part 931 is easily clogged in the inside of the hole part 931, in order to remove this chip | tip, various methods and apparatuses for washing | cleaning and drying the component 93 are various. It has been proposed (see, for example, Patent Document 1).

  As shown in FIG. 8, in the drying method, after the component 93 is cleaned in the cleaning process (step S91) and the rinsing process (step S92), the compressed air is blown through the air nozzle in the air blowing process (step S93). It spouts toward 931. Further, after blowing hot air over the entire part 93 in the blowing process (step S94) to drain and evaporate the liquid, the part 93 is dried in the vacuum drying furnace 9 in the drying process (step S95).

  However, in the conventional drying method, the time required for each step is long and the drying efficiency is low, and the energy consumption increases. In particular, as shown in FIG. 9, in the drying process (step S95) for drying the component 93 in the vacuum drying furnace 9, the operating cost and equipment cost of the drying apparatus may become excessive. .

  The present invention has been made in view of conventional problems, and provides a drying apparatus and a drying method for efficiently drying a component having a hole formed in a main body portion in a short time at a low cost. It is what.

The first invention includes a first hole formed through the front side surface to the back side surface of the main body portion having a substantially disk shape, and a second hole portion formed from the front side surface to the middle of the main body portion in the thickness direction. And a drying device for drying a component having a connecting path that connects the second hole and the middle of the first hole in the thickness direction,
An upper surface blow nozzle that discharges high-speed air in parallel along the front surface;
A lower surface blow nozzle that discharges high-speed air in parallel along the back side surface;
A communication path blow nozzle that discharges high-speed air toward the second hole;
A plurality of support portions spaced from each other for supporting the main body portion in contact with the back side surface;
The communication path blow nozzle is configured to be movable so that the distance from the opening of the second hole portion can be changed (Claim 1).

Next, the effects of the present invention will be described.
The drying apparatus of the present invention includes the upper surface blow nozzle and the lower surface blow nozzle. The upper surface blow nozzle discharges high-speed air in parallel along the front side surface, and the lower surface blow nozzle discharges high-speed air in parallel along the back side surface. Therefore, when high-speed air is discharged from the upper surface blow nozzle in parallel along the front side surface, the liquid adhering to the front side surface can be easily blown off.

  Moreover, the high-speed air creates a fast air current, and the flow area can be lower than that of other parts. Therefore, the insides of the first hole and the second hole have a relatively high pressure compared to the front side surface on which high-speed air is blown. Thereby, the movement of the air from the inside of the first hole and the second hole to the front side surface is promoted, and the liquid adhering to the inside of the first hole and the second hole is also sucked out. In this way, it can be easily discharged outside (ejector effect). Furthermore, the sucked liquid can be blown away by high-speed air discharged in parallel along the front side surface.

  Further, the lower surface blow nozzle also has the same effect on the back side surface. Therefore, the inside of the front side surface, the back side surface, the first hole portion, and the second hole portion of the component is efficiently dried in a short time by high-speed air discharged from the upper surface blow nozzle and the lower surface blow nozzle. be able to.

  However, the part to be dried has not only the first hole part and the second hole part but also a special hole structure such as the communication path. If only high-speed air is discharged from the nozzle, the interior of the communication path may not always be sufficiently dried.

  Here, the drying apparatus has a communication path blow nozzle that discharges high-speed air toward the second hole. That is, since the high speed air can be directly blown to the second hole portion by the communication path blow nozzle, the liquid that is difficult to be discharged attached to the communication path is easily blown toward the first hole portion. be able to.

  The communication path blow nozzle is configured to be movable so that the distance from the opening of the second hole can be changed. That is, since the communication path blow nozzle can be moved downward, high-speed air can be directly discharged into the second hole. Further, when the upper surface blow nozzle is used, the communication path blow nozzle is moved upward to avoid the problem of obstructing the course of the high-speed air discharged from the upper surface blow nozzle. .

  Further, the drying device has a plurality of support portions that are spaced apart from each other and support the main body portion in contact with the back side surface. Therefore, the support portion can lift the component upward, and the support portions are spaced apart from each other, so that a space serving as a path for high-speed air can be formed on the back side surface of the component. Thereby, the said lower surface blow nozzle can spray high speed air along the said back side surface, without a course being interrupted.

  In addition, as described above, the drying apparatus of the present invention can proceed with a drying operation with a simple configuration of discharging high-speed air without performing an operation that consumes a large amount of energy such as heating. Therefore, both the equipment cost and the operation cost can be reduced.

  As described above, according to the present invention, it is possible to provide a drying apparatus for efficiently drying a component having a hole formed in a main body portion in a short time at a low cost.

According to a second aspect of the present invention, there is provided a first hole formed through the front side surface to the back side surface of the main body portion having a substantially disk shape, and a second hole portion formed from the front side surface to the middle of the main body portion in the thickness direction. And a method for drying a component having a connecting path that connects the second hole and the middle of the first hole in the thickness direction,
High-speed air is discharged in parallel along the front side surface and the back side surface, and the liquid adhering to the front side surface and the back side surface is blown off, and the insides of the first hole portion and the second hole portion, respectively. A surface drying step of blowing off the liquid adhering to the outside of the main body,
An internal drying step of discharging high-speed air toward the second hole and blowing off the liquid adhering to the communication path toward the first hole;
At least after the surface drying step is performed, the internal drying step is performed, and the surface drying step is performed again (claim 6).

  The drying method of the present invention includes the surface drying step of discharging high-speed air in parallel along the front side surface and the back side surface. Therefore, in the surface drying step, when high-speed air is discharged along the front side surface, the liquid adhering to the front side surface can be easily blown off.

  Moreover, the high-speed air creates a fast air current, and the flow area can be lower than that of other parts. Therefore, the insides of the first hole and the second hole have a relatively high pressure compared to the front side surface on which high-speed air is blown. Thereby, the movement of the air from the inside of the first hole and the second hole to the front side surface is promoted, and the liquid adhering to the inside of the first hole and the second hole is also sucked out. Can be discharged to the outside (ejector effect). Further, after that, the sucked liquid can be blown off by high-speed air discharged in parallel along the front side surface.

  In addition, even when high-speed air is discharged along the back side surface, the same effects as when high-speed air is discharged onto the front side surface are obtained. Therefore, most of the inside of the front side surface, the back side surface, the first hole portion, and the second hole portion of the component can be efficiently dried in a short time by the high-speed air blown in the surface drying step.

However, since the part to be dried has not only the first hole part and the second hole part but also a special hole structure such as the communication path, only the surface drying process is performed. Then, there may be a case where the interior of the communication path cannot be sufficiently dried.
Here, in the drying method, the high-speed air is discharged toward the second hole portion, and the liquid adhering to the communication path is blown off from the second hole portion toward the first hole portion. It has a drying process. That is, since high-speed air can be directly blown toward the second hole portion, the liquid that is attached to the communication path and is difficult to be discharged can be easily blown toward the first hole portion.

  Moreover, the said drying method performs the said internal drying process after performing the said surface drying process, and also performs the said surface drying process again. That is, the liquid discharged from the inside of the second hole to the first hole in the internal drying step is discharged to the outside of the first hole due to the ejector effect in the surface drying step. be able to.

  Further, the drying method does not use large-scale equipment and does not require large-scale work such as heating. That is, since the component can be dried in a short time by a simple method of discharging high-speed air toward the component, the cost of the drying process can be reduced.

  As described above, according to the present invention, it is possible to provide a drying method for efficiently drying a component in which a hole is formed in a main body at a low cost in a short time.

It is preferable to have a discharge port (claim 2).
In this case, since the high-speed air can be discharged from the plurality of discharge ports, the component can be efficiently dried in a shorter time.

Further, the upper surface blow nozzle and the lower surface blow nozzle include the air tank having a substantially annular shape having an inner diameter larger than the outer diameter of the component, and the plurality of discharge ports provided on the inner peripheral surface of the air tank. It is preferable to have (claim 3).
In this case, since the high-speed air can be discharged from the discharge port arranged in a substantially annular shape so as to surround the part, the entire part is not only distributed from one side but the entire part. High speed air can be blown. As a result, the part can be dried more efficiently.

The upper surface blow nozzle and the lower surface blow nozzle are preferably configured to discharge high-speed air while changing the direction by switching one of the plurality of discharge ports to be used (Claim 4). .
In this case, since high-speed air is not discharged from the discharge ports facing each other, it is possible to prevent a problem that the high-speed air collides with each other and cancel each other out, and the parts are efficiently dried. be able to.

Moreover, it is preferable that the upper surface blow nozzle and the lower surface blow nozzle are configured to discharge high-speed air simultaneously and in the same direction.
In this case, the front side surface and the back side surface can be dried simultaneously and efficiently.

In the second invention (invention 6), the drying method preferably repeats the internal drying step and the surface drying step one or more times after the second surface drying step. (Claim 7).
In this case, after the second surface drying step, even if the component is not sufficiently dried, the internal drying step and the surface drying step are repeated to further dry the component. be able to.

In the surface drying step, high-speed air is preferably discharged while changing the direction.
In this case, since the high-speed air is not discharged from the directions facing each other, it is possible to prevent a problem that the high-speed air collides and cancels each other out.

In the surface drying step, high-speed air is preferably discharged simultaneously and in the same direction onto the front side surface and the back side surface.
In this case, the front side surface and the back side surface can be dried simultaneously and efficiently.

  Further, as shown in the figure, the upper surface blow nozzle 11 and the lower surface blow nozzle 12 each have an air tank 21 for temporarily storing high-pressure air sent from the air supply source 4, and a plurality of high-speed air discharged from the air tank 21. And the discharge port 22. The air tank 21 is connected to a valve 41 that opens and closes when high-pressure air is supplied or shut off from the air supply path 42.

  In this example, as shown in the figure, an air tank 21a, an air tank 21b, an air tank 21c, and an air tank 21d are disposed as the air tank 21. Further, as the discharge port 22, a discharge port 22a, a discharge port 22b, a discharge port 22c, and a discharge port 22d are provided. Further, as the valve 41, a valve 41a, a valve 41b, a valve 41c, and a valve 41d are provided.

The upper surface blow nozzle 11a is provided with an air tank 21a and a discharge port 22a and is connected to a valve 41a. The upper surface blow nozzle 11b is provided with an air tank 21b and a discharge port 22b. At the same time, it is connected to the valve 41b. The lower surface blow nozzle 12a is provided with an air tank 21c and a discharge port 22c and is connected to a valve 41c. The lower surface blow nozzle 12b is provided with an air tank 21d and a discharge port 22d. At the same time, it is connected to the valve 41d.
Further, the communication path blow nozzle 13 is configured to be movable so that the distance from the opening 320 of the second hole 32 can be changed by a vertical movement control mechanism (not shown).

Next, a method for drying the component 3 by the drying apparatus 1 of this example will be described below.
As shown in FIG. 5, the drying method of this example includes a surface drying step (step S1) and an internal drying step (step S2).

  In the surface drying step (step S1), the upper surface blow nozzle 11 and the lower surface blow nozzle 12 discharge high-speed air in parallel along the front side surface 301 and the back side surface 302 and adhere to the front side surface 301 and the back side surface 302. The liquid attached to each of the first hole portion 31 and the second hole portion 32 is blown out toward the outside of the main body portion 30.

In the surface drying step (step S1), the direction is changed, and high-speed air is simultaneously discharged to the front side surface 301 and the back side surface 302 in the same direction.
In the internal drying step (step S <b> 2), high-speed air is discharged toward the second hole portion 32, and the liquid adhering to the communication path 33 is blown off toward the first hole portion 31.

Next, a procedure for drying the component 3 based on the drying method of this example will be described in detail.
First, the component 3 cleaned by ultrasonic cleaning or the like is placed on the pallet 15 with the back side surface 301 in contact with the support portion 14 as shown in FIGS. 1, 2, and 4 (a). At this time, the component 3 is placed on the pallet 15 at a position where the second hole portion 32 and the communication path blow nozzle 13 can be connected. This operation can be automatically performed by a machine, but may be performed by a person.

Next, for example, as shown in FIGS. 1, 4A, and 5, the valve 41b and the valve 41c are opened, and high-pressure air is supplied to the air tank 21b and the air tank 21c. In this example, since the space between the air tank 21 and the discharge port 22 is narrowed down, when high-pressure air is supplied to the air tank 21, low-pressure high-speed air is discharged from the discharge port 22.
In the present example, the high-speed air refers to air having a flow rate of 10 m / s. Moreover, high-pressure air means air to which a pressure of 0.2 MPa is applied.

  Then, as shown in FIG. 4A, high-speed air is discharged in parallel along the front side surface 301 and the back side surface 302 from the upper surface blow nozzle 11b and the lower surface blow nozzle 12a, respectively. Then, by discharging high-speed air, the liquid adhering to the front side surface 301 and the back side surface 302 is blown off, and the liquid adhering to the inside of each of the first hole portion 31 and the second hole portion 32 is removed from the main body. Blow away toward the outside of the unit 30.

Next, as shown in FIGS. 4B and 5, the valve 41 b and the valve 41 c are closed, the valve 41 a and the valve 41 d are opened, and high-pressure air is supplied to the air tank 21 a and the air tank 21 d. Then, high-speed air is discharged in parallel along the front side surface 301 and the back side surface 302 from the upper surface blow nozzle 11a and the lower surface blow nozzle 12b, respectively. Thereby, the liquid adhering to the front side surface 301 and the back side surface 302 is blown off, and the liquid adhering to the inside of the first hole portion 31 and the second hole portion 32 is discharged toward the outside of the main body portion 30. .
The opening and closing of the valve 41 can be controlled by a machine, but may be performed by a person.

  Next, as shown in FIGS. 4C and 5, the valve 41 a and the valve 41 d are closed, and the communication path blow nozzle 13 is moved downward by a vertical movement control mechanism (not shown) to be connected to the second hole portion 32. At the same time, the valve 41 e is opened, and high-speed air is blown toward the communication path 33. Thereby, the liquid adhering in the communication path 33 is blown off toward the first hole portion 31.

Next, the valve 41e is closed, and the communication path blow nozzle 13 is moved upward.
Furthermore, in this example, as shown in FIG. 5, the surface drying process (step S1) is performed again, and after the second surface drying process (step S1), the internal drying process (step S2) and the surface drying process (step S1) are performed. Step S1) is repeated a plurality of times. If the drying of the part 3 can be confirmed, the present operation can be completed here.
Finally, this operation is completed by removing the dried component 3 from the pallet 15. By performing the drying process using the drying apparatus 1 of this example, the component 3 can be dried in, for example, about 20 seconds after the component 3 is placed on the pallet 15.

Whether or not the part 3 is dry can be determined by, for example, tapping the part 3 on the table and checking whether the cleaning liquid comes out as water droplets.
In addition, in the case where a plurality of second holes 32 and communication paths 33 are provided in the component 3, a plurality of communication path blow nozzles 13 may be installed. It is also possible to configure so as to be movable also in the direction.

Moreover, the said components 3 can make object the thing whose diameter is 10-15 mm and whose thickness is 4-10 mm, for example. At this time, the diameter of the communication path 33 is, for example, 0.1 to 0.5 mm. In this case, it is preferable that the discharge port 22 and the component 3 are separated from each other by about 3 to 5 mm.
Further, the component 3 and the drying device 1 of this example are not limited to the positional relationship of the present example, but, for example, are those in which the vertical positional relationship is reversed without changing the relative positional relationship between them. Can exhibit the same effect.

Next, the function and effect of this example will be described.
The drying apparatus 1 of this example includes an upper surface blow nozzle 11 and a lower surface blow nozzle 12. The upper surface blow nozzle 11 discharges high-speed air in parallel along the front side surface 301, and the lower surface blow nozzle 12 discharges high-speed air in parallel along the back side surface 302. Therefore, when high-speed air is discharged from the upper surface blow nozzle 11 along the front side surface 301 in parallel, the liquid adhering to the front side surface 301 can be easily blown off.

  Moreover, the high-speed air creates a fast air current, and the flow area can be lower than that of other parts. Therefore, the inside of the first hole portion 31 and the second hole portion 32 has a relatively high pressure as compared with the front side surface 301 on which high-speed air is blown. Thereby, the movement of air from the inside of the first hole portion 31 and the second hole portion 32 to the front side surface 301 is promoted, and the liquid adhering to the inside of the first hole portion 31 and the second hole portion 32 is sucked out. Can be easily discharged outside (ejector effect). Further, after that, the sucked liquid can be blown off by high-speed air discharged in parallel along the front side surface 301.

  On the other hand, the lower surface blow nozzle 12 also has the same effect on the back side surface 302. Therefore, the inside of the front side surface 301, the back side surface 302, the first hole portion 31, and the second hole portion 32 of the component 3 can be efficiently performed in a short time by the high-speed air discharged from the upper surface blow nozzle 11 and the lower surface blow nozzle 12. It can dry well.

  However, the part 3 to be dried has not only the first hole portion 31 and the second hole portion 32 but also a special hole structure such as the communication path 33. In some cases, it is not always possible to sufficiently dry the inside of the communication path 33 only by discharging high-speed air from the blow nozzle 12.

  Here, since the drying apparatus 1 includes the communication path blow nozzle 13 that discharges the high-speed air toward the second hole portion 32, the high-speed air can be directly blown into the second hole portion 32. Thereby, it is possible to easily blow away the liquid that is attached to the communication path 33 and is difficult to be discharged toward the first hole portion 31.

  Further, the communication path blow nozzle 13 is configured to be movable so that the distance from the opening 320 of the second hole 32 can be changed. That is, since the communication path blow nozzle 13 can be moved downward, high-speed air can be discharged directly into the second hole portion 32. Further, when the upper surface blow nozzle 11 is used, it is possible to avoid the problem of obstructing the course of the high-speed air discharged from the upper surface blow nozzle 11 by moving the communication path blow nozzle 13 upward. .

  Further, the drying apparatus 1 has a plurality of support portions 14 that are spaced apart from each other and support the main body portion 30 in contact with the back side surface 302. Therefore, the support portion 14 can lift the component 3 upward, and the support portions 14 are spaced apart from each other, so that a space serving as a path for high-speed air can be formed on the back side surface 301 of the component 3. . That is, the lower surface blow nozzle can discharge high-speed air along the back side surface 302 without being obstructed by the path.

  In addition, as described above, the drying apparatus 1 of the present example can proceed with the drying operation with a simple configuration of discharging high-speed air without performing an operation that consumes a large amount of energy such as heating. Therefore, both the equipment cost and the operation cost can be reduced.

  Each of the upper surface blow nozzle 11 and the lower surface blow nozzle 12 has an air tank 21 for temporarily storing high-pressure air sent from the air supply source 4 and a plurality of discharge ports 22 for discharging high-speed air from the air tank 21. High-speed air can be discharged from a plurality of directions. Thereby, the components 3 can be efficiently dried in a shorter time.

  As described above, according to this example, it is possible to provide a drying apparatus for efficiently drying a component having a hole formed in a main body portion at low cost in a short time.

(Example 2)
In this example, as shown in FIGS. 6 and 7, the upper surface blow nozzle 11 and the lower surface blow nozzle 12 have an air tank 21 having a substantially annular shape with an inner diameter larger than the outer diameter of the component 3, and an inner periphery of the air tank 21. It is an example of the drying apparatus 1 which has the some discharge port 22 provided in the surface 210, and the method for drying the components 3 using this.

  Further, in this example, as shown in FIG. 7, the air tank 21 formed in a substantially annular shape is divided into three groups, and a plurality of discharge ports 22 are formed on each inner peripheral surface 210 of the air tank 21. It is arranged. And the movement of the air between different groups is restrained.

  As shown in FIGS. 6 and 7, the upper surface blow nozzle 11 includes an upper surface blow nozzle 11a, an upper surface blow nozzle 11b, and an upper surface blow nozzle 11c. Further, as the lower surface blow nozzle 12, a lower surface blow nozzle 12a, a lower surface blow nozzle 12b, and a lower surface blow nozzle 12c are provided.

  The top blow nozzle 11a has an air tank 21a and a discharge port 22a. On the other hand, the lower surface blow nozzle 12a has an air tank 21d and a discharge port 22d, and the upper surface blow nozzle 11a and the lower surface blow nozzle 12a are connected to a valve 41a. That is, the high pressure air is supplied to the air tank 21a and the air tank 21d by opening the valve 21a.

  The upper surface blow nozzle 11b has an air tank 21b and a discharge port 22b, the lower surface blow nozzle 12b has an air tank 21e and a discharge port 22e, and the upper surface blow nozzle 11b and the lower surface blow nozzle 12b are: It is connected to the valve 41b. The upper surface blow nozzle 11c has an air tank 21c and a discharge port 22c. The lower surface blow nozzle 12c has an air tank 21f and a discharge port 22f. The upper surface blow nozzle 11c and the lower surface blow nozzle 12c are: It is connected to the valve 41c.

Next, a method for drying the component 3 using the drying apparatus 1 of this example will be described with reference to FIGS.
First, for example, when the valve 41a is opened, high-pressure air is supplied to the air tank 21a and the air tank 21d, and high-speed air is discharged from the discharge port 22a and the discharge port 22d. Next, when the valve 41a is closed and the valve 41b is opened, high-pressure air is supplied to the air tank 21b and the air tank 21e, and high-speed air is discharged from the discharge port 22b and the discharge port 22e. Next, after closing the valve 41b, the valve 41c is opened, whereby high-speed air is discharged from the discharge port 22c and the discharge port 22f.

As described above, in this example, the upper surface blow nozzle 11 and the lower surface blow nozzle 12 arranged in an annular shape discharge high-speed air while changing the direction by switching one of the plurality of discharge ports 22 to be used. It is configured as follows.
The upper surface blow nozzle 11 and the lower surface blow nozzle 12 are configured to discharge high-speed air simultaneously and in the same direction.
Other operations and processes are the same as those in the first embodiment.

  The upper surface blow nozzle 11 and the lower surface blow nozzle 12 of this example are an air tank 21 having a substantially annular shape with an inner diameter larger than the outer diameter of the component 3, and a plurality of discharge ports 22 provided on the inner peripheral surface of the air tank 21. And have. Thereby, high-speed air can be discharged from the discharge port 22 arranged in a substantially annular shape so as to surround the component 3. As a result, since the high-speed air can be sprayed over the entire part 3 not only from one side but also from various directions, the part 3 can be efficiently dried.

  Moreover, the upper surface blow nozzle 11 and the lower surface blow nozzle 12 are configured to discharge high-speed air while changing the direction by switching one of the plurality of discharge ports 22 to be used. Thereby, since high speed air is not discharged from the discharge port 22 of the direction which opposes, the malfunction that high speed air collides and it mutually cancels can be prevented, and the components 3 can be dried efficiently. it can.

The upper surface blow nozzle 11 and the lower surface blow nozzle 12 are configured to discharge high-speed air simultaneously and in the same direction. Thereby, the front side surface 301 and the back side surface 302 can be dried simultaneously and efficiently.
In addition, the same effects as those of the first embodiment are obtained.
