(embodiment 1)

FIG. 1 shows a cross-sectional view taken along line I-I of FIG. 2. As shown in fig. 1 and 2, the cleaning machine 10 according to embodiment 1 includes a jig 12, a nozzle 25, a pump 31, a moving device 33, a pressure reducing container 43, a container moving device 45, and a pressure reducing pump 49. The cleaning machine 10 may include the jig rotating device 11, the sealing body 17, and the gas supply device 51. The washing machine 10 washes and dries the object 21. In addition, since the nozzle 25 is located on the back of the line II-II in FIG. 1, the nozzle 25 is indicated by a two-dot chain line in FIG. 2.

The jig 12 includes a closing plate 13 and a support 19. The jig 12 may include a sealing body 17. The closing plate 13 is flat and has a mounting surface 13A and a frame 15. The closing plate 13 is not provided with an opening. The installation surface 13A is provided at the center of the closing plate 13. The installation surface 13A is a flat surface. The frame 15 surrounds the installation surface 13A. The frame 15 is disposed so as to surround the object 21 and the support 19 when viewed from the vertical direction of the closing plate 13. The frame 15 is a flat surface. The frame 15 may be provided at a position farther from the object 21 than the mounting surface 13A.

The support body 19 is disposed on the installation surface 13A. The support body 19 may include a support pin 19A, a positioning pin (not shown), and a clamp 19B. The support 19 supports the object 21 on the closing plate 13 with a gap. The clamp 19B holds the object 21.

The object 21 includes a main cleaning surface 21A and a back surface cleaning portion 21B. The object 21 is supported by the support 19 so that the main cleaning surface 21A faces a direction different from the installation surface 13A (in the figure, the opposite direction). 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 a 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 from the back surface cleaning portion 21B to the end surface of the closing plate 13 along the installation surface 13A is referred to as an insertion length 56.

The jig rotating device 11 is, for example, an NC rotary table. The gripper rotating device 11 rotates the closing plate 13 around the rotation shaft 3. The jig rotating device 11 can position and hold the rotating direction of the closing plate 13 at the drying position. Here, the drying position is a position where the closing plate 13 can be joined to the decompression container 43. In the cleaning machine 10, the drying position is a position where the closing plate 13 is perpendicular to a linear guide (guide)45A (described later).

The nozzle transfer device (hereinafter referred to as "transfer device 33") includes an X transfer device 33X, Z transfer device 33Z, Y transfer device 33Y and a nozzle rotating device (hereinafter referred to as "rotating device 33C"). The moving device 33 is preferably numerically controlled by a control device (not shown). The X-moving device 33X moves in the left-right direction (X direction) as viewed from the front of the cleaning machine 10. The Z-moving device 33Z is provided in the X-moving device 33X and moves in the vertical direction (Z direction) when viewed from the front. The Y-moving device 33Y is disposed on the Z-moving device and moves in the front-rear direction (Y direction) when viewed from the front. The rotating device 33C is disposed in the Y moving device, and rotates the nozzle 25 around the rotating shaft 5 disposed along the vertical direction, and positions the nozzle at a predetermined rotation angle. The moving device 33 can be a column transfer (column transfer) type moving device, for example. The moving device 33 can utilize, for example, japanese patent No. 6147623 or japanese patent No. 5432943.

The moving device 33 may use a vertical multi-joint robot, a horizontal multi-joint (SCARA) robot, or a parallel horizontal multi-joint robot (parallel link robot).

The nozzle 25 includes a shaft 25A, an orifice 25B, and a flow path 25C. The nozzle 25 is disposed in the rotating device 33C so as to be rotatable about the rotating shaft 5. The shaft body 25A extends along the rotation shaft 5. The shaft body 25A is preferably coaxial with the rotation shaft 5. The nozzle 25B is disposed at the tip of the shaft 25A. The spout 25B may be disposed so as to protrude from the shaft body 25A. The nozzle 25B is directed in a different direction from the rotation shaft 5. It is preferable that the nozzle 25B is directed in a direction perpendicular to the rotation axis 5. The nozzle opening 25B generates the jet 9 in a direction different from the rotation axis 5. The flow path 25C is disposed inside the shaft body 25A and extends along the rotation shaft 5. The flow path 25C connects the nozzle 25B with the rotating device 33C. A length 57 in a direction perpendicular to the rotation axis 5 at the spout 25B of the nozzle 25 is smaller than the gap length 55. A length 58 from the base end portion of the nozzle 25 to the spout 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 spout 25B via a 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 linear guide rails 45A may be one, or may be arranged in parallel to each other in a single set. The linear guide 45A extends in a direction perpendicular to the rotation shaft 3. The linear block 45B is disposed slidably on the linear guide 45A. The linear block 45B is fixed to the decompression container 43. The cylinder 45C is preferably a cylinder. The cylinder 45C may be an electric cylinder or a hydraulic cylinder. The cylinder 45C is disposed to extend and contract along the linear guide 45A. The cylinder 45C moves the decompression container 43 to the abutment position and the separation position along the linear guide 45A. Here, the abutment position is a position at which the pressure reduction container 43 is in close contact with the closing plate 13. The separated position refers to a position where the decompression container 43 is separated from the closing plate 13.

The pressure reducing container 43 includes a sealing surface 41 and an opening 43A. The pressure reducing container 43 has a box shape. The contact surface 41 is disposed around the opening 43A. The sealing surface 41 has substantially the same shape as the frame body 15. The sealing surface 41 can be in close contact with the frame 15. The decompression chamber 43 has a size capable of accommodating the support body 19 and the object 21 when in contact with the closing plate 13. The pressure reducing container 43 is joined to the closing plate 13 to form a closed container 47 (see fig. 5).

The frame 15 may be provided with a mounting groove 17A. The mounting groove 17A surrounds the entire circumference of the mounting surface 13A. A seal body 17 as an O-ring is attached to the attachment groove 17A. When the close contact surface 41 is in close contact with the frame 15, the close contact surface 41 presses the sealing body 17.

The seal 17 may be an annular rubber plate. The sealing body 17 may be provided on the sealing surface 41.

The decompression pump 49 is connected to the decompression tank 43. The decompression pump 49 exhausts the inside of the closed casing 47. The gas supply device 51 is connected to the decompression container. The gas supply device 51 supplies gas into the depressurized closed vessel 47 so that the pressures inside and outside the depressurized vessel are 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 a gas supply device 51. In this case, the exhaust gas of the decompression pump 49 is supplied to the inside of the closed casing 47 by the gas supply device 51.

The washer 10 may also include a blow nozzle 53. The air blowing nozzles 53 are provided in the pipes 54 and may be arranged side by side in the left-right direction. The air blowing nozzle 53 blows dry air toward the object 21. The air blowing nozzle 53 may be disposed outside the region where the object 21, the closing plate 13, and the support body 19 rotate.

The cleaning and drying method will be described with reference to fig. 3 to 5.

The object 21 is attached to the support 19. The pump 31 is started to pressurize the cleaning liquid. The pump 31 sends the cleaning liquid to the nozzle 25. The ejection port 25B generates the jet 9 (S1).

The nozzle 25 cleans the main cleaning surface 21A. The moving device 33 causes the nozzle 25 to face the main cleaning surface 21A, and causes the jet 9 to collide successively with the cleaning target portion. The jet 9 collides with the cleaning target portion to remove the foreign matter or burr adhering to the cleaning target portion (S2).

The jig rotating device 11 positions the closing plate 13 in parallel with the rotation 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 nozzle 25B in a direction from the closing plate 13 toward the object 21 before inserting the nozzle 25 into the gap between the object 21 and the closing plate 13.

The nozzle 25 cleans a surface of the object 21 facing the closing plate 13. The moving device 33 causes the nozzle 25 to face the back surface cleaning portion 21B and causes the jet 9 to collide with the back surface cleaning portion 21B. The jet 9 removes the foreign matter or burr adhering to the back surface cleaning portion 21B (S4).

Since length 57 is smaller than gap length 55 and length 58 is larger than insertion length 56, spout 25B can be opposed to back surface cleaning portion 21B.

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

The gripper rotating means 11 positions the closing plate 13 at the drying position (S6). Before step S6, the jig rotating device 11 may rotate the closing plate 13 to shake off the cleaning liquid adhering to the object 21, the closing plate 13, and the support member 19. Before step S6 or simultaneously with step S6, the dry air may be blown out from the air blowing nozzle 53 toward the object 21.

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

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

The gas supply device 51 supplies gas to the closed container 47. The inside of the closed casing 47 has substantially the same pressure as the outside air pressure. Next, the container moving device 45 moves the decompression container 43 to the separation position. The decompression vessel 43 is separated from the closing plate 13. The object 21 is in a detachable state from the support body 19 (S9).

In a robot cleaner using a jet flow, an opening for exposing an object is generally disposed in a jig. The jet of the cleaning liquid passing through the opening can collide with the object, and thus the surface of the object facing the jig can be cleaned. However, if the closing plate is provided with an opening, both sides of the opening of the closing plate need to be sealed with a container or a lid. If the pressure reducing container is provided on one side of the opening of the closing plate and the lid is provided on the other side, and the pressure reducing 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 configured by a flat plate without an 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 this configuration, even when the closing plate 13 having no opening is used, the jet 9 can collide with the entire surface of the object 21. The main cleaning surface 21A faces in a different direction from the closing plate 13, so the nozzle 25 can easily clean the main cleaning surface 21A.

The washer 10 has both functions of a washer and a dryer. If the washing machine 10 is used, it is not necessary to separately provide a washing machine, a drying machine, and a transfer device for transferring between the washing machine and the drying machine, and the installation area of the machine can be reduced. Further, according to the washing machine 10, the time required for carrying the washing machine to the dryer or the time required for opening and closing the gates of the washing machine and the dryer can be reduced. Moreover, the production cycle can be shortened.

According to the cleaning machine 10, the closing plate 13 is not provided with a large opening, and therefore the rigidity of the jig 12 is improved. Further, since it is not necessary to close the opening of the closing plate 13 from the back surface side of the object 21, the structure is simplified.

(embodiment 2)

The cleaning machine of embodiment 2 has a jig 112. The other structure is the same as embodiment 1.

Fig. 6 shows a cross-sectional view taken along line VI-VI of fig. 7. For convenience of explanation, in fig. 7 and 8, the object 21 is shown by a two-dot chain line. As shown in fig. 6 to 8, the jig 112 according to embodiment 2 includes a closing plate 113, a vertical plate 114, a support body 19, a frame 15, and a sealing body 17.

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

The riser 114 is vertically fixed to the closing plate 113. The risers 114 are flat plates. Openings 114A are disposed in the risers 114. The opening 114A preferably exposes substantially the entire surface of the object 21 from the riser 114. The opening 114A exposes at least the cleaning portion 21C facing the riser 114 from the riser 114. The support 19 is disposed on the riser 114. The support 19 supports the object 21 on the vertical plate. The support pin 19A is disposed vertically to the riser 114. The clamping device 19B is disposed on the riser 114. The clamp 19B fixes the object 21 to the riser 114.

The object 21 is supported by the support 19 so that the main cleaning surface 21A is parallel to the vertical plate 114. When the object 21 is supported by the support body 19, the main cleaning surface 21A faces in a direction different from the closing plate 113 or the vertical plate 114. The primary cleaning surface 21A faces the opposite side of the riser 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 face of the closing plate 113 in the direction in which the object 21 is disposed to the installation surface of the object 21 is defined as an 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 between the closing plate 113, the vertical plate 114, and the object 21 along the closing plate 113.

As shown in fig. 8, the frame 15 is disposed so as to surround the object 21, the vertical plate 114, and the support 19 when viewed in a direction (VIII direction) perpendicular to the closing plate 113. The sealing body 17 is disposed in the frame body 15.

Since the installation surface 113A has a mountain shape, the cleaning liquid is easily discharged from the installation surface 113A. When the closing plate 113 and the pressure reducing container 43 constitute the closed container 47, the amount of the cleaning liquid remaining in the closed container 47 is likely to decrease. If the amount of the cleaning liquid remaining in the closed vessel 47 is reduced, the latent heat of evaporation taken by the cleaning liquid from the closing plate 113, the decompression vessel 43, the support 19, or the object 21 when the cleaning liquid evaporates is reduced. Thus, the temperature of the object 21 is less likely to decrease, and the object 21 is likely to be dried.

Since the object 21 is provided on the vertical plate 114, the nozzle 25 is easily brought close to the back surface cleaning portion 21B. Since the riser 114 has the opening 114A, the nozzle 25 causes the jet 9 to collide with the cleaning portion 21C from the back surface of the riser 114 through the opening 114A.

(embodiment 3)

As shown in fig. 9, the cleaning machine 200 of embodiment 3 includes a cleaning chamber 261, a partition 262, an intermediate shutter 263, a drying chamber 265, a nozzle 25, a moving device 33, a turntable 269, two jig rotating devices 11, two jigs 112, a decompression container 43, and a container moving device 45. Partition 262 separates cleaning chamber 261 and drying chamber 265. The partition 262 has a transfer port 262A at the lower side. The intermediate shutter 263 opens and closes the transfer port 262A. Turntable 269 has two table tops 269A. The jig rotating device 11 and the jig 112 are disposed on the table surfaces 269A. Turntable 269 is disposed between cleaning chamber 261 and drying chamber 265. The turntable 269 is rotated to distribute 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 disposed in the cleaning chamber 261. The decompression chamber 43 and the chamber transfer device 45 are disposed in the drying chamber 265.

The operation of the washer 200 will be described below with reference to fig. 10. In the cleaning chamber 261, a cleaning process is performed (steps S1 to S5). In the drying chamber 265, a drying process is performed (steps S6 to S9). After the drying process is completed in the drying chamber 265, the object 21 is taken out from the jig 112 in the drying chamber 265 (S21). The new object 21 is mounted on 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. Subsequently, the intermediate shutter 263 opens the conveyance port 262A (S23). Finally, the turntable 269 rotates (S24). Then, the object 21 cleaned in the cleaning chamber 261 moves to the drying chamber 265, and the newly mounted object 21 moves to the cleaning chamber 261. According to the cleaning machine 200, the cleaning process and the drying process can be performed in parallel.
