When the object 21 is supported by the support 19, the back surface cleaning portion 21B faces the closing plate 13. The back surface cleaning portion 21B faces the gap between the closing plate 13 and the object 21. The length of the gap between the back surface cleaning portion 21B and the closing plate 13 is referred to as a gap length 55. The length along the installation surface 13A from the back surface cleaning portion 21B to the end surface of the closing plate 13 is referred to as an insertion length 56.

The jig rotating device 11 is, for example, an NC circular table. The jig rotating device 11 rotates the closing plate 13 about the rotation shaft 3. The jig rotating device 11 can position and hold the rotation direction of the closing plate 13 in the dry phase. Here, the dry phase is a phase in which the closing plate 13 can be joined to the decompression container 43. In the washing machine 10, the drying phase is a phase in which the closing plate 13 is perpendicular to the linear guide 45A (described later).

The nozzle moving device (hereinafter referred to as “moving device 33”) includes an X moving device 33X, a Z moving device 33Z, a Y moving device 33Y, and a nozzle rotating device (hereinafter referred to as “rotating device 33C”). Preferably, the moving device 33 is numerically controlled by a controller (not shown). The X movement device 33X moves in the left-right direction (X direction) when viewed from the front of the washing machine 10. The Z moving device 33Z is installed on the X moving device 33X and moves in the vertical direction (Z direction) when viewed from the front. The Y moving device 33Y is arranged in the Z moving device and moves in the front-back direction (Y direction) when viewed from the front. The rotating device 33C is arranged in the Y moving device, and rotates the nozzle 25 about the rotating shaft 5 arranged in the up-down direction and positions it at a predetermined rotation angle. As the moving device 33, for example, a column traverse type moving device can be used. As the moving device 33, for example, Japanese Patent No. 6147623 and Japanese Patent No. 5432943 can be used.
The moving device 33 may use a vertical articulated robot, a SCARA robot, or a parallel link robot.

The nozzle 25 includes a shaft body 25A, an injection port 25B and a flow path 25C. The nozzle 25 is arranged in the rotating device 33C so that it can rotate around the rotating shaft 5. The shaft 25A extends along the rotation axis 5. Preferably, the shaft body 25A is coaxial with the rotation shaft 5. The injection port 25B is arranged at the tip of the shaft 25A. The injection port 25B may be arranged so as to project from the shaft body 25A. The injection port 25B faces a direction different from that of the rotating shaft 5. Preferably, the injection port 25B faces the direction perpendicular to the rotation axis 5. The jet 25B produces a jet flow 9 in a direction different from that of the rotating shaft 5. The flow path 25C is disposed inside the shaft body 25A and extends along the rotating shaft 5. The flow path 25C connects the injection port 25B to the rotating device 33C. The length 57 of the nozzle 25 along the direction of the injection port 25B is smaller than the gap length 55. The length 58 from the base end of the nozzle 25 to the injection port 25B is larger than the insertion length 56.

The pump 31 is connected to the rotating device 33C. The pump 31 is connected to the injection port 25B via the rotating device 33C.

The container moving device 45 includes a linear guide 45A, a linear block 45B, and a cylinder 45C. The linear guide 45A is fixed. The number of the linear guides 45A may be one or one set may be arranged in parallel with each other. The linear guide 45A extends in the direction perpendicular to the rotary shaft 3. The linear block 45B is arranged so as to be slidable on the linear guide 45A. The linear block 45B is fixed to the decompression container 43. The cylinder 45C is preferably an air cylinder. The cylinder 45C may be an electric cylinder or a hydraulic cylinder. The cylinder 45C is arranged so as to expand and contract along the linear guide 45A. The cylinder 45C moves the decompression container 43 to the contact position and the separation position along the linear guide 45A. Here, the contact position refers to a position where the decompression container 43 comes into close contact with the closing plate 13. The separated position is a position where the decompression container 43 is separated from the closing plate 13.

The decompression container 43 includes a contact surface 41 and an opening 43A. The decompression container 43 has a box shape. The contact surface 41 is arranged around the opening 43A. The contact surface 41 has substantially the same shape as the frame 15. The contact surface 41 can be in close contact with the frame 15. The decompression container 43 has a size capable of accommodating the support 19 and the object 21 when it contacts the blocking plate 13. The decompression container 43 is combined with the closing plate 13 to form a closed container 47 (see FIG. 5).

The mounting groove 17A may be arranged in the frame body 15. The mounting groove 17A surrounds the entire circumference of the installation surface 13A. The sealing body 17, which is an O-ring, is mounted in the mounting groove 17A. When the contact surface 41 is in close contact with the frame body 15, the contact surface 41 crushes the sealing body 17.
The sealing body 17 may be a ring-shaped rubber plate. The sealing body 17 may be provided on the contact surface 41.

The decompression pump 49 is connected to the decompression container 43. The decompression pump 49 exhausts the inside of the closed container 47. The gas supply device 51 is connected to the decompression container. The gas supply device 51 supplies gas into the decompressed closed container 47 to make the pressure inside and outside the decompression container substantially the same. The gas supply device 51 can use a vacuum break valve or a gas supply valve.
The exhaust port of the decompression pump 49 may be connected to the gas supply device 51. In this case, the exhaust gas of the decompression pump 49 is supplied into the closed container 47 through the gas supply device 51.

Furthermore, the washing machine 10 may include an air blow nozzle 53. The air blow nozzles 53 may be installed in the pipe 54 and arranged side by side in the left-right direction. The air blow nozzle 53 jets dry air toward the target object 21. The air blow nozzle 53 may be arranged outside the region where the object 21, the closing plate 13 and the support 19 are rotated.

A cleaning and drying method will be described with reference to FIGS.
The object 21 is mounted on the support 19. The pump 31 is activated and pressurizes the cleaning liquid. The pump 31 sends the cleaning liquid to the nozzle 25. The jet port 25B produces the jet flow 9 (S1).

The nozzle 25 cleans the main cleaning surface 21A. The moving device 33 makes the nozzle 25 face the main cleaning surface 21A and causes the jet stream 9 to collide with the cleaning target portion one after another. The jet stream 9 collides with the cleaning target portion to remove foreign matters and burrs adhering to the cleaning target portion (S2).

The jig rotating device 11 positions the closing plate 13 so as to be parallel to the rotating shaft 5. As shown in FIG. 4, the moving device 33 inserts the nozzle 25 into the gap between the object 21 and the closing plate 13 (S3).
The moving device 33 may position the injection port 25B in the direction from the closing plate 13 to the target 21 before inserting the nozzle 25 into the gap between the target 21 and the closing plate 13.

The nozzle 25 cleans the surface of the object 21 facing the closing plate 13. The moving device 33 makes the nozzle 25 face the back surface cleaning portion 21B and causes the jet stream 9 to collide with the back surface cleaning portion 21B. The jet 9 removes foreign matters and burrs adhering to the back surface cleaning portion 21B (S4).
Since the length 57 is smaller than the gap length 55 and the length 58 is larger than the insertion length 56, the injection port 25B can face the back surface cleaning portion 21B.

The pump 31 stops discharging the cleaning liquid. The nozzle 25 stops the generation of the jet flow 9. The moving device 33 retracts the nozzle 25 from the closing plate 13 and the object 21 (S5).

The jig rotating device 11 positions the closing plate 13 in the dry phase (S6). Prior to step S6, the jig rotating device 11 may rotate the closing plate 13 to shake off the cleaning liquid attached to the object 21, the closing plate 13 and the support 19. Prior to step S6 or simultaneously with step S6, dry air may be jetted from the air blow nozzle 53 toward the target object 21.

The container moving device 45 moves the decompression container 43 to the contact position. As shown in FIG. 5, the close contact surface 41 is in close contact with the frame body 15, and the closing plate 13 closes the opening 43A. The decompression container 43 forms a closed container 47 together with the closing plate 13. The sealing body 17 seals the gap between the contact surface 41 and the frame body 15. The object 21 and the support 19 are housed in the closed container 47 (S7). Since the closing plate 13 is not provided with an opening, the closed container 47 can be configured only by the closing plate 13 and the decompression container 43.

The decompression pump 49 is driven. The decompression pump 49 decompresses the inside of the decompression container. The cleaning liquid adhering to the object 21, the closing plate 13, and the support 19 takes away evaporation latent heat from the surroundings and evaporates. The object 21 is dried (S8).

The gas supply device 51 sends the gas to the closed container 47. The pressure inside the closed container 47 is substantially the same as the outside air pressure. Subsequently, the container moving device 45 moves the decompression container 43 to the separated position. The decompression container 43 is separated from the closing plate 13. The object 21 is ready to be removed from the support 19 (S9).

In a robot cleaning machine using a jet, an opening for exposing an object is usually arranged in a jig. Since the jet of the cleaning liquid that has passed through the opening can collide with the target object, the surface of the target object facing the jig can be cleaned. However, if an opening is provided in the closing plate, it becomes necessary to seal both sides of the opening of the closing plate with a container or a lid. If the decompression container is provided on one side of the opening of the closing plate and the lid is provided on the other side, and the decompression container and the lid are brought into close contact with the closing plate to form the closed container 47, the apparatus becomes complicated.
Therefore, in the cleaning machine 10, the closing plate 13 is formed of a flat plate having no opening, the main cleaning surface 21A is arranged in a direction different from that of the closing plate 13, and a gap is provided between the closing plate 13 and the object 21. The nozzle 25 can be inserted along the closing plate 13 into the gap between the closing plate and the object. With these configurations, the jet flow 9 can collide with the entire surface of the object 21 even when the closing plate 13 having no opening is used. Since the main cleaning surface 21A faces a direction different from that of the closing plate 13, the nozzle 25 easily cleans the main cleaning surface 21A.
The washer 10 has both the functions of a washer and a dryer. If the washer 10 is used, it is not necessary to separately install a washer, a dryer, and a transfer device for transferring between the washer and the dryer, and the installation area of the machine can be reduced. Further, according to the washer 10, it is possible to reduce the transfer time from the washer to the dryer and the shutter open/close time of the washer and the dryer. And the production lead time can be shortened.
According to the washing machine 10, since the blocking plate 13 does not have a large opening, the rigidity of the jig 12 is improved. Moreover, since it is not necessary to close the opening of the closing plate 13 from the back side of the target object 21, the configuration is simplified.

(Second embodiment)
The washing machine of the second embodiment has a jig 112. Other configurations are similar to those of the first embodiment.
FIG. 6 shows a sectional view taken along line VI-VI of FIG. For convenience, in FIG. 7 and FIG. 8, the object 21 is shown by a chain double-dashed line. As shown in FIGS. 6 to 8, the jig 112 of the second embodiment includes a closing plate 113, a stand plate 114, a support body 19, a frame body 15 and a sealing body 17.

The installation surface 113A is formed in a mountain shape. The installation surface 113A is composed of two flat surfaces arranged in contact with each other.

The stand plate 114 is vertically fixed to the closing plate 113. The stand plate 114 is a flat plate. An opening 114A is arranged in the stand plate 114. The opening 114A preferably exposes substantially the entire surface of the object 21 from the standing plate 114. The opening 114A exposes at least the cleaning portion 21C facing the stand plate 114 from the stand plate 114. The support 19 is arranged on the stand plate 114. The support 19 supports the object 21 against the standing plate. The support pin 19A is arranged vertically to the stand plate 114. The clamp 19B is arranged on the stand plate 114. The clamp 19B fixes the object 21 to the standing plate 114.

The object 21 is supported by the support 19 so that the main cleaning surface 21A is parallel to the stand plate 114. When the object 21 is supported by the support 19, the main cleaning surface 21A faces a direction different from that of the closing plate 113 and the stand plate 114. The main cleaning surface 21A faces the surface opposite to the stand plate 114. At this time, the back surface cleaning portion 21B faces the closing plate 113. A gap is provided between the installation surface 113A and the object 21. A gap having a gap length 55 is provided between the installation surface 113A and the object 21. The length from the end surface of the closing plate 113 in the direction in which the object 21 is arranged to the installation surface of the object 21 is defined as the insertion length 56.
Here, the gap length 55 is greater than the length 57. Insertion length 56 is less than length 58. The nozzle 25 is inserted along the closing plate 113 between the closing plate 113, the stand plate 114 and the object 21.

As shown in FIG. 8, the frame body 15 is arranged so as to surround the target object 21, the stand plate 114, and the support body 19 when viewed from the direction perpendicular to the closing plate 113 (VIII direction). The sealing body 17 is arranged on the frame body 15.

Since the installation surface 113A is mountain-shaped, the cleaning liquid is easily discharged from the installation surface 113A. When the closing plate 113 and the decompression container 43 constitute the closed container 47, the amount of the cleaning liquid remaining inside the closed container 47 is likely to decrease. If the amount of the cleaning liquid remaining inside the closed container 47 decreases, the evaporation latent heat taken by the cleaning liquid from the closing plate 113, the decompression container 43, the support 19 and the object 21 when the cleaning liquid evaporates decreases. Then, the temperature of the target object 21 is less likely to decrease, and the target object 21 is easily dried.
Since the target object 21 is installed on the stand plate 114, the nozzle 25 easily approaches the back surface cleaning portion 21B. Since the stand plate 114 has the opening 114A, the nozzle 25 can cause the jet flow 9 to collide with the cleaning portion 21C from the back surface of the stand plate 114 through the opening 114A.

(Third Embodiment)
As shown in FIG. 9, the washing machine 200 according to the third embodiment includes a washing chamber 261, a partition plate 262, an intermediate shutter 263, a drying chamber 265, a nozzle 25, a moving device 33, a turntable 269, two jig rotating devices 11, It has two jigs 112, a decompression container 43 and a container moving device 45. The partition plate 262 partitions the cleaning chamber 261 and the drying chamber 265. The partition plate 262 has a transfer port 262A below. The intermediate shutter 263 opens and closes the transport port 262A. The turntable 269 has two table surfaces 269A. The jig rotating device 11 and the jig 112 are arranged on each of the table surfaces 269A. The turntable 269 is arranged in the middle of the cleaning chamber 261 and the drying chamber 265. The turntable 269 rotates to index one of the two jigs 112 to the cleaning chamber 261 and the other to the drying chamber 265. The nozzle 25 and the moving device 33 are arranged in the cleaning chamber 261. The decompression container 43 and the container moving device 45 are arranged in the drying chamber 265.

The operation of the washing machine 200 will be described below with reference to FIG. In the cleaning chamber 261, a cleaning process (steps S1 to S5) is executed. In the drying chamber 265, the drying process (steps S6 to S9) is executed. In the drying chamber 265, after the drying process is completed, the target object 21 is taken out from the jig 112 in the drying chamber 265 (S21). A new object 21 is attached to the jig 112 in the drying chamber 265 (S22). Steps S1 to S5 are executed in parallel with steps S6 to S9 and steps S21 to S22. Next, the intermediate shutter 263 opens the transport port 262A (S23). Finally, the turntable 269 turns (S24). Then, the target object 21 cleaned in the cleaning chamber 261 moves to the drying chamber 265, and the newly mounted target object 21 moves to the cleaning chamber 261. According to the washing machine 200, the washing process and the drying process can be performed in parallel.
