First, the cleaning chamber 16 will be described.

  A cleaning chamber 16 is formed in a part of the space 14. Inside the cleaning chamber 16, for example, a gripping portion 26 that grips the workpiece W and a cleaning mechanism for supplying a cleaning liquid to the workpiece W are accommodated.

  The workpiece W is an object to be cleaned, and an example is an automobile part. In the cleaning chamber 16, the workpiece W is cleaned with a cleaning liquid or the like, and foreign matters such as chips or cutting oil remaining on the surface of the workpiece W, the inside of the casting core hole, the inside of the screw hole, and the like are removed.

  The gripping part 26 is a jig for fixing the workpiece W, for example. The jig has a predetermined gripping mechanism, and can fix the workpiece W or release the workpiece W. The jig is configured to be rotatable about a predetermined rotation axis (not shown), and the workpiece W can be rotated about the rotation axis while the workpiece W is gripped.

The cleaning header 28 has, for example, a configuration arranged inside the cleaning chamber 16 and a configuration arranged outside the cleaning chamber 16 or the housing 12.

  A configuration in which the cleaning header 28 is disposed outside the cleaning chamber 16, more preferably outside the housing 12 may be employed. A configuration in which the cleaning header 28 is disposed inside the cleaning chamber 16 or the housing 12 is also possible, but the cleaning header 28 is disposed outside the cleaning chamber 16 or the housing 12 so that the cleaning chamber 16 or the housing 12 is disposed. The body 12 can be downsized.

  In particular, in the configuration in which the cleaning header 28 is disposed outside the cleaning chamber 16, only at least a part (for example, a tip portion) of the cleaning nozzle 30 is located on the inner side of the cleaning chamber 16, Injection becomes possible.

  A first switching damper portion 32 is provided in or near the cleaning chamber 16. The first switching damper portion 32 functions as a side wall of the cleaning chamber 16 when cleaning the workpiece W, and as a part of a channel wall that forms the air channel 88 when removing moisture from the workpiece W during the air blowing process. Function. As a result, the first switching damper portion 32 has two functions, so that the number of parts and the manufacturing cost can be reduced, and the downsizing of the cleaning blow device 10 can be realized.

  The first switching damper portion 32 includes a first switching damper main body portion 34 formed in a flat plate shape, and a first switching damper support portion 36 that supports the first switching damper main body portion 34. The first switching damper support portion 36 is connected to the rotation shaft 40. When the rotary shaft 40 rotates about the axis, the first switching damper main body 34 is guided to a position (first position) that functions as a side wall of the cleaning chamber 16 (see FIG. 1), or the air flow path 88 It is led to a position (second position) that functions as a part of the flow path wall (see FIG. 2).

  The first switching damper main body 34 is provided so as to be rotatable about the axis of the rotary shaft 40 by receiving the driving force of the driving source 82 (see FIG. 3). Here, the drive source 82 may be configured to directly apply a driving force to the first switching damper main body 34, or may be configured to directly apply a driving force to the first switching damper support portion 36. Further, the drive source 82 may be configured to directly drive the rotation shaft 40 by directly applying a driving force to the rotation shaft 40.

  For example, an air cylinder is used as the drive source 82, but a hydraulic cylinder, a motor, or another drive source may be used.

  Here, the interpretation that “the first switching damper portion 32 functions as a sidewall of the cleaning chamber 16” means that the first switching damper portion 32 constitutes all or at least a part of the sidewall of the cleaning chamber 16. .

  Specifically, the first switching damper main body 34 of the first switching damper 32 constitutes all or at least a part of the side wall of the cleaning chamber 16. The case where the first switching damper main body 34 constitutes at least a part of the side wall of the cleaning chamber 16 is, for example, that an opening is formed in the side wall of the cleaning chamber 16 and the first switching damper main body 34 is open. The structure which opens and closes a part corresponds. When the first switching damper main body 34 closes the opening, there is no gap in the side wall of the cleaning chamber 16, and the cleaning liquid can be stored in the cleaning chamber 16. On the other hand, when the first switching damper main body 34 opens the opening, the opening on the side wall of the cleaning chamber 16 is exposed as it is, and the cleaning chamber 16 functions as a part of the air flow path 88.

  Moreover, the case where the 1st switching damper part 32 comprises all the side walls of the washing | cleaning chamber 16 means that the 1st switching damper main-body part 34 of the 1st switching damper part 32 comprises the whole side wall of the washing | cleaning chamber 16, for example. It is. In this case, the first switching damper main body 34 forms the cleaning chamber 16 in a watertight manner as a side wall of the cleaning chamber 16 at the first position, and breaks the partition formation of the cleaning chamber 16 at the second position. Open the inside of.

  A drain damper 42 is provided at or near the cleaning chamber 16. The drain damper 42 functions as a bottom wall of the cleaning chamber 16 when the workpiece W is cleaned, and also functions as a part of a channel wall that forms the air channel 88 when moisture is removed from the workpiece W during the air blowing process. To do. Thereby, the drain damper part 42 has two functions, and can reduce the number of parts and manufacturing cost, and can implement | achieve size reduction of an apparatus by extension.

  The drain damper part 42 includes a drain damper main body part 44 formed in a flat plate shape, and a drain damper support part 46 that supports the drain damper main body part 44. The drain damper support part 46 is connected to the rotating shaft 48. As the rotary shaft 48 rotates about the axis, the drain damper main body 44 is guided to a position (first position) that functions as the bottom wall of the cleaning chamber 16 (see FIG. 1) or the flow of the air flow path 88. It is led to a position (second position) that functions as a part of the road wall (see FIG. 2).

  The drain damper main body 44 is provided so as to be rotatable around the axis of the rotary shaft 48 under the driving force of the driving source 84 (see FIG. 3). The driving source 84 may be configured to directly apply a driving force to the drain damper main body 44 or may be configured to directly apply a driving force to the drain damper support 46. Further, the drive source 84 may be configured to directly apply a driving force to the rotary shaft 48 to drive the rotary shaft 48 to rotate.

  For example, an air cylinder is used as the drive source 84, but a hydraulic cylinder, a motor, or another drive source may be used.

  Here, the interpretation of “the drainage damper portion 42 functions as the bottom wall of the cleaning chamber 16” means that the drainage damper portion 42 constitutes all or at least a part of the bottom wall of the cleaning chamber 16.

  Specifically, the drain damper main body 44 of the drain damper 42 constitutes all or at least a part of the bottom wall of the cleaning chamber 16. The case where the drain damper main body 44 constitutes at least a part of the bottom wall of the cleaning chamber 16 is, for example, that an opening is formed in the bottom wall of the cleaning chamber 16, and the drain damper main body 44 defines the opening. A configuration that opens and closes corresponds. When the drain damper main body 44 closes the opening, there is no gap in the bottom wall of the cleaning chamber 16, and the cleaning liquid can be stored in the cleaning chamber 16. On the other hand, when the drain damper main body 44 opens the opening, the opening of the bottom wall of the cleaning chamber 16 is exposed as it is, and the cleaning chamber 16 functions as a part of the air flow path 88.

  The case where the drain damper 42 constitutes the entire bottom wall of the cleaning chamber 16 is, for example, that the drain damper main body 44 of the drain damper 42 constitutes the entire bottom wall of the cleaning chamber 16. In this case, the drainage damper main body 44 forms the cleaning chamber 16 in a watertight manner as the bottom wall of the cleaning chamber 16 at the first position, and breaks the partition formation of the cleaning chamber 16 at the second position. Open the inside.

  As shown in FIG. 1, in the cleaning chamber 16, a cleaning tank 38 that can be partitioned by the side wall of the housing 12, the first switching damper portion 32, and the drain damper portion 42 is formed. Cleaning of the workpiece W using the cleaning liquid is performed inside.

(Airflow generation room)
Next, the airflow generation chamber 18 will be described.

  An air flow generation chamber 18 is formed in a part of the space 14. The air flow generation chamber 18 is formed at a position on the upstream side in the flow direction of air in the air flow with respect to the cleaning chamber 16. An air flow generation source 50 for generating an air flow (air flow) is accommodated in the air flow generation chamber 18.

  Note that “air” in the present embodiment does not mean compressed air. That is, it means air that is generated by a fan or the like and flies in the airflow.

  As the airflow generation source 50, a fan or the like for generating an airflow inside the housing 12 is used instead of a compressor or the like for supplying compressed air. The fan rotates about its axis by a drive source (not shown) such as a motor.

  Here, the opening of the air flow generation chamber 18 is provided with a predetermined inclination angle with respect to the horizontal direction. That is, the air flow generation chamber 18 has an air blow inclined upper wall 52 inclined by a predetermined inclination angle with respect to the horizontal direction, and an air blow inclined lower wall 54 formed substantially parallel to the air blow inclined upper wall 52. doing. The air blow inclined upper wall 52 and the air blow inclined lower wall 54 function as part of the flow path wall of the air flow path 88.

  Specifically, the opening of the air flow generation chamber 18 is formed to be inclined downward from the mist removal chamber 24 side toward the cleaning chamber 16 side. In other words, the air flow generation chamber 18 is formed so as to incline upward in a direction away from the cleaning chamber 16 side with respect to the cleaning chamber 16 side.

  The air blow inclined upper wall 52 is formed so as to be inclined downward from the mist removing chamber 24 side toward the cleaning chamber 16 side. In other words, the air blow inclined upper wall 52 is formed so as to incline upward along the direction away from the cleaning chamber 16 side with respect to the cleaning chamber 16 side.

  In a state where the airflow generation source 50 is installed on the air blow inclined lower wall 54, the rotation shaft 51 serving as the rotation center of the airflow generation source 50 is also inclined by a predetermined inclination angle with respect to the horizontal direction. For this reason, the air in the airflow generated by the airflow generation source 50 is intensively applied to the workpiece W held by the holding portion 26, and the blowing effect is enhanced.

  The air in the airflow generated by the airflow generation source 50 flows toward the work W along the air blow inclined upper wall 52. Therefore, the air blow inclined upper wall 52 is inclined, so that the work W is moved to the environment of the air flow. Increases the air flow when placed in Thereby, the blow effect with respect to the workpiece | work W becomes high.

  For the part where the airflow is difficult to enter or the concave part where the airflow is difficult to enter on the side surface of the workpiece W, the compressed air supply means is used partially or limitedly, and the compressed air is applied to the part or the recess. You may spray. Thereby, a motion is given to the said part or the said recessed part, it becomes possible to wrap the workpiece | work W with the air in airflow environment, and to scatter a water | moisture content from the workpiece | work W.

  Further, as described above, since the air flow generation chamber 18 is provided with a predetermined inclination angle with respect to the horizontal direction, the cleaning liquid used for cleaning in the cleaning chamber 16 is supplied from the cleaning tank 38 of the cleaning chamber 16. In the case of overflow, etc., entry of the cleaning liquid into the airflow generation chamber 18 is prevented. That is, when the cleaning liquid enters the air flow generation chamber 18, it is necessary to climb the air blow inclined lower wall 54, but the cleaning liquid falls due to the influence of gravity. For this reason, it becomes difficult for the cleaning liquid to enter the airflow generation chamber 18, and even if the cleaning liquid enters the airflow generation chamber 18, it can be easily drained to the outside of the airflow generation chamber 18.

(Connection flow path)
Next, the connection channel 20 will be described.

  In addition, a connection flow path 20 is provided in a partial region of the space portion 14. The connection flow path 20 connects the air flow generation chamber 18 and the cleaning chamber 16 and functions as an air flow path 88 through which air in the air flow circulates. The connection flow path 20 is located upstream of the cleaning chamber 16 in the air flow direction.

  A second switching damper portion 56 is provided in the connection flow path 20 or in the vicinity thereof. As shown in FIG. 1, the second switching damper portion 56 functions as an intrusion prevention wall for preventing the cleaning liquid from entering the airflow generation chamber 18 at the first position when the workpiece W is cleaned. Further, as shown in FIG. 2, the second switching damper portion 56 functions as a part of the flow path wall that forms the air flow path 88 at the second position when the workpiece W is placed in an airflow environment. . Thereby, the 2nd switching damper part 56 will have two functions, can reduce a number of parts and manufacturing cost, and can implement | achieve size reduction of an apparatus by extension.

  The 2nd switching damper part 56 has the 2nd switching damper main-body part 58 formed in flat form, and the weight part 59, for example.

  The second switching damper main body 58 is connected to the rotating shaft 60. When the rotary shaft 60 rotates around the axis, the second switching damper main body 58 is guided to a position (first position) that functions as an intrusion prevention wall that blocks at least a part of the opening of the airflow generation chamber 18 ( 1) or a position (second position) that functions as a part of the flow path wall of the air flow path 88 (see FIG. 2).

  The weight portion 59 is configured so that the second switching damper main body 58 always stops at the first position in a state where the second switching damper main body 58 does not receive the wind pressure of the air in the airflow generated by the airflow generation source 50. To function as a weight balancer.

  The second switching damper main body 58 rotates around the axis of the rotation shaft 60 while receiving the wind pressure of the air in the airflow generated by the airflow generation source 50 and resisting the gravity of the weight portion 59. In other words, the second switching damper main body 58 moves from the first position to the second position using the wind pressure of the air in the airflow generated by the airflow generation source 50. As a result, it is not necessary to separately provide a drive source for driving the second switching damper main body 58, the number of parts and the manufacturing cost can be reduced, and the apparatus can be miniaturized.

  The second switching damper main body 58 rotates around the axis of the rotation shaft 60 by the action of the weight 59 when the workpiece W is not receiving the wind pressure of the air in the airflow, such as when the workpiece W is washed. Move from position 2 to the first position. The second switching damper main body 58 functions as an intrusion prevention wall for the airflow generation chamber 18 at the first position.

  Naturally, the second switching damper portion 56 may be configured in the same manner as the configuration of the first switching damper portion 32. In this case, since a drive source is separately provided, automatic control related to the rotational drive of the second switching damper portion 56 becomes possible.

  The connection flow path 20 includes a connection inclined wall 62 for guiding the air in the airflow generated by the airflow generation source 50 to the work W gripped by the gripping portion 26. The connection inclined wall 62 is formed to be inclined downward from the air flow generation chamber 18 side toward the cleaning chamber 16 side. In other words, the connection inclined wall 62 is formed so as to incline upward along a direction away from the cleaning chamber 16 side with the cleaning chamber 16 side as a reference. Accordingly, air in the airflow generated by the airflow generation source 50 flows toward the workpiece W along the connection inclined wall 62. Therefore, the connection inclined wall 62 is inclined, so that the workpiece W is placed in the airflow environment. Increased air flow. As a result, the blow effect on the workpiece W is increased.

  Here, as shown in FIG. 1, when cleaning the workpiece W, the first switching damper main body 34 is guided to a position (first position) that functions as a side wall of the cleaning chamber 16, and the second switching damper main body 58. Is guided to a position (first position) that functions as an intrusion prevention wall into the airflow generation chamber 18. Thereby, it is possible to prevent the cleaning liquid or the like overflowing from the cleaning chamber 16 from entering the airflow generation chamber 18 when the workpiece W is being cleaned in the cleaning chamber 16.

  On the other hand, as shown in FIG. 2, when the work W is placed in an airflow environment, the first switching damper main body 34 falls to the connection flow path side so as to be substantially horizontal, and the flow path wall of the air flow path 88 It is led to a position (second position) that functions as a part. Similarly, the second switching damper main body 58 also falls to the connection flow path side so as to be substantially horizontal, and is guided to a position (second position) that functions as a part of the flow path wall of the air flow path 88. .

  At this time, the distal end portion of the first switching damper main body portion 34 and the distal end portion of the second switching damper main body portion 58 are overlapped over a predetermined region, and no gap is formed in the flow path wall of the connection flow path 20. Thus, both are connected.

  Here, the area of the opening 21 of the air flow path 88 inside the connection flow path is configured to be narrowed from the air flow generation chamber 18 side toward the cleaning chamber 16 side. In other words, the opening area of the opening 21 on the cleaning chamber 16 side of the air channel 88 inside the connection channel is set to be smaller than the opening area on the airflow generation chamber 18 side. For this reason, the flow velocity of air on the air flow generation chamber 18 side of the air flow path 88 inside the connection flow passage becomes faster than the flow velocity of air on the cleaning chamber 16 side. As a result, the work W is placed in an airflow environment, and residual moisture (for example, cleaning liquid) attached to the surface of the work W is peeled off. As a result, the blow effect on the workpiece W is increased.

  The opening area of the air flow path 88 inside the connection flow path is defined in the connection flow path 20 by the first switching damper portion 32, the second switching damper portion 56, and the housing 12 during the air blowing process. It means the area of the opening of the air flow path 88.

(Cleaning fluid drainage chamber)
Next, the cleaning liquid drain chamber 22 will be described.

  A cleaning liquid drain chamber 22 is formed in a part of the space 14. The cleaning liquid drain chamber 22 functions mainly as a room for draining the cleaning liquid used for cleaning in the cleaning chamber 16 and simultaneously connects the cleaning chamber 16 and the mist removal chamber 24. The cleaning liquid drain chamber 22 functions as an air flow path 88 through which air flows.

  The cleaning liquid drain chamber 22 is provided with a tank unit 62 for storing or collecting the cleaning liquid.

  The cleaning liquid drain chamber 22 is formed at a downstream position in the air flow direction with respect to the cleaning chamber 16.

  The cleaning liquid drain chamber 22 is provided with a third switching damper portion 64. As shown in FIG. 1, the third switching damper portion 64 functions as an intrusion prevention wall for preventing the cleaning liquid from entering the mist removal chamber 24 when the cleaning liquid is drained from the cleaning chamber 16. Further, as shown in FIG. 2, the third switching damper portion 64 functions as a part of the flow path wall that forms the air flow path 88 when the work W is placed in an airflow environment. Thereby, the 3rd switching damper part 64 will have two functions, can reduce a number of parts and manufacturing cost, and can implement | achieve size reduction of an apparatus by extension.

  The third switching damper portion 64 has a third switching damper main body portion 66 formed in a flat plate shape, and a third switching damper support portion 68 that supports the third switching damper main body portion 66. The third switching damper support portion 68 is connected to the rotation shaft 70. When the rotary shaft 70 rotates about the axis, the third switching damper main body 66 functions as an intrusion prevention wall for preventing the cleaning liquid from entering the mist removal chamber 24 when the cleaning liquid of the workpiece W is drained. It is led to a position (first position) (see FIG. 1) or led to a position (second position) that functions as a part of the flow path wall of the air flow path 88 (see FIG. 2).

  The third switching damper main body 66 is provided so as to be rotatable about the axis of the rotary shaft 70 by receiving the driving force of the driving source 86 (see FIG. 3). The drive source 86 may be configured to directly apply a driving force to the third switching damper main body 66 or may be configured to directly apply a driving force to the third switching damper support portion 68. Furthermore, the drive source 86 may be configured to drive the rotation shaft 70 by directly applying a driving force to the rotation shaft 70.

  For example, an air cylinder is used as the drive source 86, but a hydraulic cylinder, a motor, or other drive sources may be used.

  Here, as shown in FIG. 1, when the workpiece W is cleaned, the drain damper main body 44 is guided to a position (first position) that functions as the bottom wall of the cleaning chamber 16, and the third switching damper main body 66 is The cleaning liquid is guided to an inclined position (first position) that functions as a wall that prevents the cleaning liquid from entering the mist removal chamber 24. As a result, when the cleaning liquid used for cleaning the workpiece W in the cleaning chamber 16 is drained from the cleaning chamber 16, the cleaning liquid collides with the third switching damper main body 66, thereby canceling the flow of the cleaning liquid. Intrusion into the mist removal chamber 24 can be prevented.

  On the other hand, as shown in FIG. 2, when the workpiece W is placed in an airflow environment, the third switching damper main body 66 falls down so as to be substantially horizontal, and the flow of the air flow path 88 formed in the cleaning liquid drainage chamber 22. It is led to a position (second position) that functions as a part of the road wall. The drain damper main body 44 is guided to a position (second position) where the bottom wall of the cleaning chamber 16 is opened.

  At this time, as shown in FIG. 2, the tip of the third switching damper main body 66 and the tip of the drainage damper main body 44 remain close to each other, and a large gap is formed in the flow path wall of the cleaning liquid drainage chamber 22. It is set not to be. Thereby, one flow path wall of the air flow path 88 is formed from the drain damper main body portion 44 to the third switching damper main body portion 66.

(Mist removal room)
Next, the mist removal chamber 24 will be described.

  A mist removal chamber 24 is formed in a partial region of the space portion 14. The mist removal chamber 24 is formed at a downstream position in the air flow direction with respect to the cleaning chamber 16 or the cleaning liquid drain chamber 22.

  The mist removal chamber 24 is provided between the cleaning liquid drain chamber 22 and the airflow generation chamber 18, and the air that has passed through the cleaning chamber 16 enters the mist removal chamber 25 through the cleaning liquid drain chamber 22. Then, the air that has passed through the mist removal chamber 24 enters the airflow generation chamber 18.

  The mist removing chamber 24 accommodates a mist removing device 72 that separates and removes liquid particulates (defined as mist) contained in the air flowing through the space 14 from the air. By providing the mist removing device 72, the mist in the air is removed, so that it is possible to prevent the mist from adhering to and contaminating the work W gripped by the air flow generation source 50 and the grip portion 26. .

  The mist removing device 72 is installed so as to block the air flow path 88 in the mist removing chamber so that air can pass therethrough. The capturing surface 73 that captures the mist of the mist removing device 72 is provided so as to be inclined with respect to the opening surface 25 </ b> A in the opening 25 of the mist removing chamber 24. In other words, the capturing surface 73 of the mist removing device 72 is not parallel to the opening surface 25A in the opening 25 of the mist removing chamber 24 but is inclined by a predetermined inclination angle. For this reason, the contact area (or contact area) with respect to the mist removal apparatus 72 of air becomes large. As a result, the effect of trapping mist in the mist removing device 72 is enhanced, and the air that has passed through the mist removing device 72 contains almost no mist. As a result, it is possible to prevent the mist from adhering to the air flow generation source 50 and the workpiece W to be contaminated.

  The opening surface 25A in the opening 25 of the mist removing chamber 24 is not limited to the time of cleaning or air blowing, but means the opening surface when the opening determined by the design of the mist removing device 72 is cut in the cross-sectional direction.

  Here, the mist removal chamber 24 has an inclined bottom portion 74 inclined downward toward the cleaning chamber 16 side or the cleaning liquid drain chamber 22 side. In other words, with reference to the cleaning chamber 16 side or the cleaning liquid drainage chamber 22 side, the inclined bottom portion 74 is inclined upward in a direction away from the cleaning chamber 16 side or the cleaning liquid drainage chamber 22 side. For this reason, it becomes difficult for the cleaning liquid on the cleaning chamber 16 side or the cleaning liquid drain chamber 22 side to enter the mist removing chamber 24 due to the influence of gravity. Thereby, it can suppress that the mist removal chamber 24 and the mist removal apparatus 72 are contaminated with mist.

  The inner wall of the mist removing chamber 24 is provided with a cleaning unit 76 for removing dirt attached to the inner wall of the mist removing chamber 24. The cleaning unit 76 has, for example, a cleaning nozzle 78, and the cleaning liquid is ejected from the cleaning nozzle 78 at a predetermined timing. The cleaning liquid sprayed from the cleaning nozzle 78 strikes the inner wall of the mist removing chamber 24 vigorously, the inner wall of the mist removing chamber 24 is cleaned, and the mist removing chamber 24 is maintained in a clean state. As a result, it is possible to prevent the mist from adhering again to the air flowing through the mist cleaning chamber 24, and as a result, the air containing the mist can be prevented from coming into contact with the workpiece W and being contaminated.

(Control system)
Next, the control system will be described.

  As shown in FIG. 3, the operation of the cleaning blow apparatus 10 is controlled by the control unit 80. Specifically, a program for executing the cleaning process and the air blowing process is stored in the ROM 80B of the control unit 80, and the program is executed by the CPU 80A. In addition, as an example, the drive source 82, 84, 86 of the first switching damper unit 32, the drain damper unit 42, and the third switching damper unit 64, the airflow generation source 50, and the like are electrically connected to the control unit 80. ing.

  Next, the operation and effect of the cleaning blow device 10 of the present embodiment will be described. For convenience of explanation, the work W cleaning process and the work W air blowing process will be described separately.

(Washing process)
As shown in FIG. 1, in the process of cleaning the workpiece W, the workpiece W is gripped and cleaned by the gripping portion 26 of the cleaning chamber 16. At this time, the first switching damper main body 34 stops at the first position and functions as a side wall of the cleaning chamber 16, and the second switching damper main body 58 stops at the first position and enters the air flow generation chamber 18. It functions as a wall that prevents the intrusion of cleaning fluid. Further, the drain damper main body 44 stops at the first position and functions as the bottom wall of the cleaning chamber 16, and the third switching damper main body 66 stops at the first position and the cleaning liquid to the mist removing chamber 24, etc. It functions as an intrusion prevention wall.

  In the cleaning chamber 16, the workpiece W gripped by the gripping portion 26 is cleaned inside the cleaning tank 38 defined by the inner wall of the housing 12, the first switching damper main body portion 34, and the drainage damper main body portion 44. The cleaning liquid is ejected from the nozzle 30 and the cleaning process is executed. At this time, a predetermined amount of cleaning liquid is stored in the cleaning tank 38.

  Here, in the cleaning process of the workpiece W, the cleaning liquid may overflow from the cleaning tank 38. However, the second switching damper main body 58 stops at the first position, and the opening of the airflow generation chamber 18 serves as an intrusion prevention wall. Since at least a part is blocked, the cleaning liquid can be prevented from entering the airflow generation chamber 18.

  Further, since the third switching damper main body 66 stops at the first position and blocks at least a part of the opening of the mist removal chamber 24 as an intrusion prevention wall, the cleaning liquid enters the mist removal chamber 24. Can be prevented.

  In this way, the workpiece W is cleaned, and the process proceeds to the air blow process which is the next process.

(Air blow process)
As shown in FIG. 2, in the air blowing process of the workpiece W, the first switching damper main body 34 moves to the second position to open the side wall of the cleaning chamber 16 and the flow path wall of the air flow path 88. Act as part. Further, the second switching damper main body 58 moves to the second position and functions as a part of the channel wall of the air channel 88. At this time, the distal end portion of the first switching damper main body portion 34 and the distal end portion of the second switching damper main body portion 58 overlap with each other to form one continuous flow path wall.

  Further, the drain damper main body 44 moves to the second position, opens the bottom wall of the cleaning chamber 16, and functions as a part of the flow path wall of the air flow path 88. Further, the third switching damper main body 66 moves to the second position and functions as a part of the flow path wall of the air flow path 88. At this time, the distal end portion of the drain damper main body portion 44 and the distal end portion of the third switching damper main body portion 66 are close to each other, and one continuous flow path wall is formed inside the cleaning liquid drain chamber 22.

  In this manner, an air flow path 88 that is one closed circulation flow path including the air flow generation chamber 18, the connection flow path 20, the cleaning chamber 16, the cleaning liquid drain chamber 22, and the mist removal chamber 24 is formed. Air in the airflow generated by the airflow generation source 50 circulates in the air flow path 88 as an airflow.

  In the air blowing process, air in the airflow generated by the airflow generation source 50 in the airflow generation chamber 18 enters the cleaning chamber 16 through the connection flow path 20. In the cleaning chamber 16, moisture or the like adhering to the work W is pulled by the air in the airflow environment, and peeled off from the work W and removed. In the airflow environment, air flies at a predetermined flow velocity.

  Thereafter, the air enters the mist removal chamber 24 from the cleaning chamber 16 through the cleaning liquid drain chamber 22. The air that has entered the mist removing chamber 24 passes through the mist removing device 72. At this time, liquid fine particles (mist) contained in the air are captured by the mist removing device 72. For this reason, the air that has passed through the mist removing device 72 does not contain mist. The air that does not contain the mist flows from the mist removing chamber 24 to the air flow generation chamber 18, flows again toward the cleaning chamber 16, hits the work W, and scatters the cleaning liquid from the surface. Thereafter, air enters the mist removal chamber 24 through the cleaning liquid drain chamber 22, and the mist contained in the air is removed by the mist removal device 72. Thereafter, this is repeated.

  As described above, according to the cleaning blow apparatus 10 of the present embodiment, the cleaning chamber 16, the air flow generation chamber 18, and the mist removal chamber 24 are mainly formed in the space 14 of the single casing 12. The installation space for the cleaning blow device 10 is reduced as compared with the case where each room is constituted by separate devices.

  Each embodiment described above is only an example for explaining the present invention, and various modifications can be made without departing from the gist of the present invention.
