And a conveying device 3 for carrying out the operation.

  The fluid supply / discharge device 2 is connected to a case 6 having an accommodating portion 5 that can accommodate the workpiece 1 therein, and supplies and discharges cleaning liquid and compressed air into the accommodating portion 5. Specifically, the fluid supply / discharge device 2 includes a cleaning liquid supply / discharge device 2A that supplies and discharges cleaning liquid and an air supply / discharge device 2B that supplies and discharges compressed air.

  As shown in FIG. 2, the transport device 3 includes an index table 7 that supports a plurality of cases 6, and an index motor 8 that rotates around the index table 7. The case 6 is disposed on the same circumference around the rotation axis of the index table 7 and is conveyed to a desired position by driving and stopping the index motor 8. In addition, illustration of the conveying apparatus 3 is abbreviate | omitted in FIG.

  The transport device 3 transports the case 6 to a cleaning position 3A corresponding to the cleaning liquid supply / discharge device 2A and a moisture removal position 3B corresponding to the air supply / discharge device 2B (see FIG. 1). In the case 6, in addition to the cleaning position 3 </ b> A and the moisture removal position 3 </ b> B, the transfer device 3 automatically sets the work 1 on the case 6 and the work 6 is automatically removed from the case 6. It is also conveyed to the removal position 3D. As described above, the transfer device 3 sequentially transfers the workpiece 1 to the four predetermined positions. Specifically, the sheet is transported in the order of the setting position 3C, the cleaning position 3A, the moisture removal position 3B, and the removal position 3D.

  Each of the setting position 3C, the cleaning position 3A, the moisture removal position 3B, and the removal position 3D is arranged at intervals of 90 degrees. Similarly, four cases 6 are supported by the index table 7 at intervals of 90 degrees. Therefore, when the index table 7 is stopped, all the cases 6 are arranged corresponding to any of the positions 3A to 3D, and the workpiece 1 is set, the workpiece 1 is washed, the moisture is removed from the workpiece 1, One of the steps of removing the workpiece 1 is performed.

  The case 6 includes a support case 10 that supports the workpiece 1, and an upper case 11 that is releasably connected to the support case 10 and defines the accommodating portion 5. In this way, the case 6 is configured to be openable and closable so that the workpiece 1 can be taken in and out of the accommodating portion 5. Hereinafter, a case used for the work 1 cleaning process is referred to as a cleaning process case, and a case used for the work 1 water removal process is referred to as a water removal case.

  As shown in FIG. 2, the support case 10 is a substantially cylindrical member, and is inserted into the hollow portion of the jig 15 supported by the index table 7 at an interval of 90 degrees, and an annular flange provided at the end portion. It is supported by a spring 16 interposed between the portion 10d and the jig 15. The spring 16 is compressed by the weight of the support case 10 and urges the support case 10 in a direction to be removed from the jig 15.

  The support case 10 includes a discharge passage 10a for discharging the cleaning liquid or compressed air in the storage portion 5 to the outside, and a large diameter portion 10b that communicates with the discharge passage 10a and has an inner circumference larger than that of the workpiece 1. . The discharge passage 10 a and the large diameter portion 10 b are formed in series along the axial direction of the support case 10. The support case 10 is supported by the index table 7 such that the opening of the discharge passage 10a opens vertically downward and the opening of the large diameter portion 10b opens vertically upward.

  Since the discharge passage 10a has a smaller diameter than the large-diameter portion 10b, a step portion 10c is formed at the boundary between the discharge passage 10a and the large-diameter portion 10b, and the workpiece 1 is locked to the step portion 10c. In this way, the workpiece 1 is supported by the support case 10.

  The support case 10 is sequentially transported to the four positions 3A to 3D by the rotation of the index table 7, and is used in common in the four steps.

  Below the index table 7, when the support case 10 is positioned at the cleaning position 3A, the cleaning liquid supply / discharge device 2A communicates with the discharge passage 10a of the support case 10 and discharges the cleaning liquid to a tank (not shown). A cleaning liquid discharge pipe 27 is provided. The lower part of the cleaning liquid discharge pipe 27 is fixed to the base 20 of the cleaning apparatus 100. As described above, the cleaning liquid supply / discharge device 2 </ b> A is configured to be detachable from the support case 10.

  Further, below the index table 7, when the support case 10 is located at the moisture removal position 3B, the air supply / discharge device 2B is connected to the discharge passage 10a of the support case 10 and discharges compressed air to the outside. An air exhaust pipe (not shown) is provided. The lower part of the compressed air discharge pipe is fixed to the base 20 of the cleaning apparatus 100 in the same manner as the cleaning liquid discharge pipe 27. Thus, the air supply / discharge device 2B is also configured to be detachable from the support case 10.

  The upper case 11 is a substantially cylindrical member, and is disposed vertically above the cleaning position 3A and used for the cleaning process of the work 1, and the water removal of the work 1 disposed vertically above the water removal position 3B. It consists of the blow case 11B used for a process.

  The cleaning case 11 </ b> A and the blow case 11 </ b> B are coupled to a long plate-like table 22 that is supported via an L-shaped column 21 that stands on the base 20. The table 22 is arranged in parallel above the index table 7.

  A cylinder case 24 that supports the air cylinder 23 in the vertical direction is coupled to the end of the support column 21, and the table 22 is coupled to the tip of a piston rod (not shown) that slidably moves within the air cylinder 23. Is done. Therefore, by driving the air cylinder 23, the table 22 moves in the vertical direction, and accordingly, the cleaning case 11 </ b> A and the blow case 11 </ b> B move in a direction toward or away from the index table 7. The air cylinder 23 and the table 22 correspond to moving means.

  The cleaning case 11 </ b> A has a supply passage 11 </ b> Aa for supplying the cleaning liquid into the storage portion 5, and a large-diameter portion 11 </ b> Ab that communicates with the supply passage 11 </ b> Aa and has an inner diameter larger than that of the workpiece 1. The supply passage 11Aa and the large diameter portion 11Ab are formed in series along the axial direction of the cleaning case 11A. The cleaning case 11A is supported by the table 22 so that the opening of the supply passage 11Aa opens vertically upward and the opening of the large diameter portion 11Ab opens vertically downward.

  Similarly, the blow case 11 </ b> B also has a supply passage 11 </ b> Ba for supplying compressed air into the accommodating portion 5, and a large diameter portion 11 </ b> Bb that communicates with the supply passage 11 </ b> Ba and has an inner diameter larger than that of the work 1. The supply passage 11Ba and the large diameter portion 11Bb are formed in series along the axial direction of the blow case 11B. The blow case 11B is supported by the table 22 so that the opening of the supply passage 11Ba opens vertically upward and the opening of the large diameter portion 11Bb opens vertically downward.

  The table 22 is coupled with a cleaning liquid supply pipe 25 of a cleaning liquid supply / discharge device 2A that guides the cleaning liquid from a cleaning liquid supply source (not shown), and the cleaning liquid supply pipe 25 is connected to the supply passage 11Aa of the cleaning case 11A. As described above, the cleaning case 11A is provided so as to be connected to the cleaning liquid supply / discharge device 2A, is supplied with the cleaning liquid from the cleaning liquid supply / discharge device 2A, and is used only for the cleaning process of the workpiece 1. The cleaning liquid supply source and the cleaning liquid supply pipe 25 are connected via a flexible hose (not shown).

  Further, the table 22 is coupled with a compressed air supply pipe 26 of an air supply / discharge device 2B that guides compressed air from a compressed air supply source (not shown), and the compressed air supply pipe 26 is connected to the supply passage 11Ba of the blow case 11B. Connected to. As described above, the blow case 11B is connected to the air supply / discharge device 2B, is supplied with compressed air from the air supply / discharge device 2B, and is used only for the water removal process of the workpiece 1. The compressed air supply source and the compressed air supply pipe 26 are connected via a flexible hose (not shown).

  Since the cleaning case 11A is arranged vertically above the cleaning position 3A, when the support case 10 is transported to the cleaning position 3A by the index table 7, the cleaning case 11A and the support case 10 are arranged coaxially. It will be. At this time, the opening end of the large-diameter portion 10b of the support case 10 and the opening end of the large-diameter portion 11Ab of the cleaning case 11A face each other. Therefore, by driving the air cylinder 23 and lowering the table 22, the opening ends of the air cylinder 23 come into contact with each other, and the housing portion 5 is hermetically defined by the support case 10 and the cleaning case 11 </ b> A. At this time, since the support case 10 moves downward while compressing the spring 16, the lower end contacts the upper end of the cleaning liquid discharge pipe 27, and the discharge passage 10a of the support case 10 and the cleaning liquid discharge pipe 27 communicate with each other. Since the spring 16 is in a compressed state, the support case 10 is urged in a direction in close contact with the cleaning case 11A, and the accommodating portion 5 is sealed.

  Since the blow case 11B is arranged vertically above the moisture removal position 3B, the blow case 11B and the support case 10 are coaxial when the support case 10 is conveyed to the moisture removal position 3B by the index table 7. Will be placed on top. Therefore, by driving the air cylinder 23 and lowering the table 22, the opening ends of the air cylinder 23 come into contact with each other, and the housing portion 5 is hermetically defined by the support case 10 and the blow case 11 </ b> B. At this time, since the support case 10 moves downward while compressing the spring 16, the lower end contacts the upper end of the compressed air discharge pipe, and the discharge passage 10a of the support case 10 and the compressed air discharge pipe communicate with each other. Since the spring 16 is in a compressed state, the support case 10 is urged in a direction in close contact with the blow case 11B, and the accommodating portion 5 is sealed.

  As described above, the support case 10 that supports the workpiece 1 is conveyed from the cleaning position 3A to the moisture removal position 3B, and is sealed by the cleaning case 11A and the blow case 11B at the respective positions 3A and 3B. At the cleaning position 3A, the work 1 is cleaned by supplying and discharging the cleaning liquid by the cleaning liquid supply / discharge device 2A. At the water removal position 3B, the moisture on the surface of the work 1 is supplied by supplying and discharging compressed air by the air supply / discharge device 2B. Removal is performed.

  As described above, the support case 10 is commonly used in the cleaning process and the water removal process, whereas the cleaning case 11A and the blow case 11B are used exclusively in the cleaning process and the water removal process, respectively. That is, the cleaning process case includes the support case 10 and the cleaning case 11A, and the moisture removal process case includes the support case 10 and the blow case 11B.

  Here, the interval between the cleaning case 11 </ b> A coupled to the table 22 and the blow case 11 </ b> B is the same as the interval between adjacent support cases 10 supported by the index table 7. Therefore, by driving the air cylinder 23 and lowering the table 22, the support case 10 disposed at the cleaning position 3A and the moisture removal position 3B is simultaneously sealed by the cleaning case 11A and the blow case 11B.

  Next, with reference to FIG. 4, the structure in the accommodating part 5 is demonstrated in detail. FIG. 4A is a schematic view of a state in which the cleaning liquid is supplied to and discharged from the container 5 of the cleaning process case and the workpiece 1 is being cleaned, and FIG. 4B is a b- in FIG. 4A. It is sectional drawing which shows b cross section. Note that the arrows shown in FIG. 4A indicate the flow direction of the cleaning liquid.

  In the state in which the support case 10 and the cleaning case 11A are integrated, the accommodating portion 5 is defined by the large diameter portion 10b and the large diameter portion 11Ab.

  Since the outer diameter of the workpiece 1 is larger than the inner diameter of the discharge passage 10a of the support case 10, the workpiece 1 is in a state where the back surface 1a is in contact with the stepped portion 10c that is the boundary between the discharge passage 10a and the large diameter portion 10b. It arrange | positions in the accommodating part 5. FIG.

  As described above, the work 1 is arranged in the housing portion 5 so that the back surface 1a closes the discharge passage 10a by its own weight and the pressure of the cleaning liquid supplied from the supply passage 11Aa of the cleaning case 11A into the housing portion 5. Is done.

  Four grooves are formed at intervals of 90 degrees on the inner periphery of the large-diameter portion 10b and the large-diameter portion 11Ab, that is, the inner periphery of the accommodating portion 5, and these grooves communicate with the supply passage 11Aa and the groove passage 30 through which the cleaning liquid passes. Configured as

  Further, as shown in FIG. 4B, a groove-shaped communication path 31 is formed on the stepped portion 10c so as to face the back surface 1a of the work 1 and connect the accommodating portion 5 and the discharge passage 10a. In this way, the communication path 31 is defined between the surface of the step portion 10 c and the back surface 1 a of the workpiece 1. Therefore, the accommodating portion 5 and the discharge passage 10 a are always communicated with each other via the communication passage 31, and the pressure of the cleaning liquid that passes through the communication passage 31 acts on the back surface 1 a of the workpiece 1. Specifically, the communication passage 31 is formed by communicating each groove passage 30 and the discharge passage 10a.

  A recess 32 that is continuous with the groove passage 30 is formed in the stepped portion 10c. The recessed portion 32 is formed facing the back surface 1a of the workpiece 1 so that the pressure of the cleaning liquid in the housing portion 5 acts on the back surface 1a of the workpiece 1.

  As described above, the cleaning liquid supplied from the supply passage 11 </ b> Aa into the accommodating portion 5 is formed between the inner periphery of the accommodating portion 5 and the outer periphery of the work 1 by forming each passage in the accommodating portion 5. It flows through the gap 33 and the groove passage 30, passes through the communication passage 31, and is discharged to the discharge passage 10a. When the cleaning liquid passes through the communication path 31, the fluid force of the cleaning liquid acts on the back surface 1a of the work 1, and the work 1 receives a force that rises in the axial direction. Here, when the workpiece 1 is placed on the stepped portion 10c, the opening area of the communication path 31 is small, and the flow rate of the cleaning liquid flowing through the communication path 31 is large. As a result, the work 1 moves up in the accommodating portion 5 in the axial direction. In addition to the fluid force generated by the cleaning liquid flowing through the communication path 31, the workpiece 1 is also subjected to an upward force by the pressure of the cleaning liquid guided to the recess 32. In FIG. 4A, the right side of the center line is a view when the workpiece 1 is raised.

  When the workpiece 1 rises in the axial direction, the back surface 1a of the workpiece 1 is separated from the stepped portion 10c and the communication passage 31 is opened, so that the flow rate of the cleaning liquid flowing into the discharge passage 10a is reduced. As a result, the fluid force acting on the back surface 1a of the workpiece 1 is reduced, the workpiece 1 descends in the axial direction by its own weight, and again comes into contact with the stepped portion 10c to define the communication path 31.

  In this way, the workpiece 1 is washed while swinging in the axial direction by repeatedly raising and lowering due to the fluid force of the cleaning liquid passing through the communication path 31. By cleaning the work 1 by swinging it in the axial direction, the cleaning effect is promoted, and the work 1 can be cleaned in a short time.

  When the dimensional difference between the outer diameter of the work 1 and the inner diameter of the accommodating portion 5 is small and the gap 33 between them is small, the flow rate of the cleaning liquid flowing through the gap 33 is reduced. The fluid force may be reduced. However, since the cleaning liquid flows through the groove passage 30 formed in the inner periphery of the accommodating portion 5 to ensure the flow rate, the fluid force of the cleaning liquid passing through the communication path 31 is ensured even when the gap 33 is small, The workpiece 1 swings in the axial direction.

  Although the case of the cleaning process case used in the cleaning process of the workpiece 1 has been described above, the same structure is applied to the moisture removal process case used in the moisture removal process of the workpiece 1. Therefore, even when compressed air is supplied to the moisture removal process case to remove moisture on the surface of the workpiece 1, the workpiece 1 swings in the axial direction by its own weight and the fluid force of the compressed air passing through the communication path 31. While the water is removed.

  Next, the operation of the cleaning apparatus 100 configured as described above will be described.

  First, among the four support cases 10 supported by the index table 7, the workpiece 1 is set in the support case 10 located at the set position 3C.

  Next, the support case 10 on which the workpiece 1 is set is transported to the cleaning position 3 </ b> A by the transport device 3. At the cleaning position 3A, the cleaning liquid supply pipe 25, the cleaning case 11A, the support case 10, and the cleaning liquid discharge pipe 27 are arranged coaxially.

  By driving the air cylinder 23, the cleaning case 11 </ b> A is lowered toward the support case 10. The cleaning case 11 </ b> A and the support case 10 are integrated when their open ends come into contact with each other, and form a cleaning process case.

  The cleaning liquid is supplied into the sealed housing 5 in the cleaning case through the cleaning liquid supply pipe 25 of the cleaning liquid supply / discharge device 2A.

  The workpiece 1 in the storage unit 5 is cleaned by the cleaning liquid that passes through the storage unit 5. Further, the workpiece 1 is cleaned while swinging in the axial direction by its own weight and the fluid force of the cleaning liquid passing through the communication path 31.

  After the work 1 is cleaned, the air cylinder 23 is driven to raise the cleaning case 11A and separate it from the support case 10.

  Next, the support case 10 is transported to the moisture removal position 3 </ b> B by the transport device 3. At the moisture removal position 3B, the compressed air supply pipe 26, the blow case 11B, the support case 10, and the compressed air discharge pipe are arranged coaxially.

  By driving the air cylinder 23, the blow case 11 </ b> B is lowered toward the support case 10. The blow case 11 </ b> B and the support case 10 are integrated when the opening ends of the blow case 11 </ b> B come into contact with each other, and form a moisture removal process case.

  Compressed air is supplied through the compressed air supply pipe 26 of the air supply / discharge device 2 </ b> B into the sealed housing 5 in the moisture removal process case.

  Moisture is removed from the work 1 in the housing part 5 by blowing compressed air onto the surface. Further, the surface moisture of the work 1 is removed while swinging in the axial direction by its own weight and the fluid force of the compressed air passing through the communication passage 31.

  After the moisture removal process of the work 1 is completed, the blow cylinder 11B is raised and separated from the support case 10 by driving the air cylinder 23.

  Next, the support case 10 is transported to the removal position 3D by the transport device 3, and the workpiece 1 is removed from the support case 10 at the removal position 3D.

  As described above, the cleaning process and the moisture removing process of the workpiece 1 are performed. Since four lower cases are supported by the index table 7, the steps of setting, cleaning, removing moisture and removing the workpiece 1 are performed simultaneously.

  According to the present embodiment, the following effects are obtained.

  The workpiece 1 is accommodated in the accommodating portion 5 and is cleaned by the cleaning liquid flowing through the accommodating portion 5. Therefore, since the washing tank for immersing the workpiece 1 is not required, the apparatus can be configured compactly.

  Moreover, since the workpiece | work 1 is wash | cleaned when the pressurized washing | cleaning liquid hits the whole surface of the workpiece | work 1, it can wash | clean efficiently in a short time.

  Moreover, since the workpiece | work 1 is wash | cleaned separately one by one, according to the surface area and dirt condition of the workpiece | work 1, it can carry out by flowing the washing | cleaning liquid of the minimum required for washing | cleaning to the accommodating part 5. FIG. Accordingly, wasteful consumption of the cleaning liquid is prevented, and cleaning can be performed efficiently.

  Further, since the workpiece 1 is cleaned while being swung in the axial direction by its own weight and the fluid force of the cleaning liquid passing through the communication path 31, the cleaning effect is promoted, and the workpiece 1 can be cleaned in a shorter time. it can.

  Further, in the cleaning apparatus 100, after the workpiece 1 is cleaned, moisture is removed from the surface of the workpiece 1 by the same procedure as that for cleaning, that is, by replacing the medium supplied into the case 6 with compressed air from the cleaning liquid. Thus, both washing and moisture removal can be performed with a simple apparatus.

  The present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.

  For example, in the above embodiment, the support case 10 is commonly used in the cleaning process and the water removal process by being transported by the transport device 3, and the cleaning case 11A and the blow case 11B are respectively used in the cleaning process and the water removal process. It explained that it was used exclusively in the process. However, two support cases 10 may be provided so as to be used exclusively in the cleaning process and the water removal process. That is, the cleaning process case and the moisture removal process case may be configured as completely different cases. In that case, only the workpiece 1 is transported from the cleaning process case to the moisture removal process case.

  Further, the cleaning process case and the moisture removal process case may be configured in exactly the same case. In that case, the cleaning liquid is supplied into the housing portion 5 of the case 6 to clean the workpiece 1, and then the compressed air is supplied into the housing portion 5 without opening the case 6 to remove moisture from the workpiece 1. .

  Further, in the above embodiment, the case 6 is composed of the support case 10 and the upper case 11, and the housing portion 5 is defined by both. However, the housing portion 5 is formed only in the support case 10. And you may make it comprise the upper case 11 in a cap-shaped member.

  The cleaning apparatus according to the present invention can be used as an apparatus for cleaning a workpiece soiled with oil or the like.
