The tip portion 44 is rotatable in the J6 direction around the longitudinal axis L5 of the hand portion 47. Here, the longitudinal axis L5 is perpendicular to the rotation axis L4.

  Operations such as rotation of the first arm portion 45, the second arm portion 46, the hand portion 47, and the tip portion 44 are performed by a drive mechanism (not shown) including a motor and a power transmission portion. By rotating the first arm portion 45, the arm 42 is moved to the closed state (see FIG. 4) in which the tip portion 44 is close to the vertical axis L1 which is the rotation center axis of the main body tower 50, or when the tip portion 44 is the vertical axis. The state changes to the open state (see FIG. 5) separated from L1.

  As the gripping device 48 (see FIG. 1) attached to the tip portion 44, for example, a clamp device that grips the work W with an air clamp, a magnet, or the like can be used. The gripping device 48 is replaceable according to the type of the work W, for example.

  As shown in FIG. 1, the cleaning device 1 includes a cover 61 attached to the main body tower 50. Specifically, the cover 61 is fixedly attached to the flange portion 54 of the main body tower 50. Therefore, the cover 61 also rotates in conjunction with the rotation of the main body tower 50. The fixing of the cover 61 to the main body tower 50 is performed by a screw member here, but the present invention is not limited to this, and other fixing means such as welding may be used. The cover 61 partitions the cleaning chamber 20 and the drying chamber 30 when cleaning and drying the work W. That is, the washing chamber 20 and the drying chamber 30 are partitioned and partitioned by the cover 61 both when the work W is washed and when it is dried.

  The cleaning device 1 also includes a partition plate 80 installed between the cleaning chamber 20 and the drying chamber 30. In the present embodiment, the partition plate 80 has vertically long rectangular plates 81 and 82 installed at both ends of the boundary between the cleaning chamber 20 and the drying chamber 30, respectively. The partition plate 80 has a partition opening 83 through which the cover 61 can pass when the work W is transported from the cleaning chamber 20 to the drying chamber 30. Here, the vertically long rectangular space between the pair of plates 81, 82 constitutes the partition opening 83.

  The cover 61 has a side surface 62 that is arranged outside the main body tower 50 in the radial direction and covers the periphery of the main body tower 50. The side surface 62 has a cylindrical shape facing the edge portion of the partition plate 80 that extends in the vertical direction of the partition opening portion 83. The cover 61 also has an upper surface 64 that covers the upper portion of the side surface 62. The upper surface 64 can improve the rigidity of the cover 61, but can be omitted if the rigidity required for the entire cover 61 can be secured.

  The side surface 62 of the cover 61 is formed with a cover opening 63 through which the arm 42 can pass when the tip 44 of the arm 42 is separated from the vertical axis L1. The cover opening 63 has a vertically long slit shape in order to make the opening area as small as possible and allow the arm 42 and the work W to pass therethrough.

  The supply device 90 includes a tank (not shown) for storing the cleaning liquid, a pump (not shown) for sucking and delivering the cleaning liquid from the tank, a filter (not shown) for filtering the collected cleaning liquid, and the like. The supply device 90 supplies the cleaning liquid stored in the tank to the cleaning nozzle 23 by the operation of the pump.

  A cleaning nozzle block 22 (cleaning unit) is arranged inside the cleaning chamber 20, and the cleaning nozzle block 22 has, for example, a rectangular frame shape. The cleaning nozzle block 22 is provided with a plurality of cleaning nozzles 23 that inject a cleaning liquid toward the inside. The cleaning liquid is supplied from the supply device 90 to the cleaning nozzle 23 via a flow path (not shown) formed inside the cleaning nozzle block 22. Therefore, the cleaning liquid can be jetted as a jet from the cleaning nozzles 23 in a plurality of directions onto the work W. Since the cleaning liquid can be sprayed simultaneously from many cleaning nozzles 23, many jet flows are generated in the cleaning tank 21.

  A cleaning tank 21 may be fixedly installed on the bottom plate 18 so as to surround the cleaning nozzle block 22. A drain port and a drain valve (not shown) are provided at the bottom of the cleaning tank 21. Since the cleaning tank 21 can be filled with and discharged with the cleaning liquid, the cleaning apparatus 1 can selectively perform cleaning in air and cleaning in water.

A drying nozzle block 32 (drying unit) is arranged inside the drying chamber 30, and the drying nozzle block 32 has, for example, a rectangular frame shape. The drying nozzle block 32 is provided with a plurality of drying nozzles 33 that inject dry air toward the inside. The dry air for air blow is pressurized by a blower (not shown) and is supplied to the drying nozzle 33 through a flow path (not shown) formed inside the drying nozzle block 32. Therefore, the dry air can be jetted from the drying nozzles 33 to the work W in a plurality of directions.
In addition, instead of the drying nozzle block 32 or together with the drying nozzle block 32, the decompression tank 31 may be fixedly provided on the bottom plate 18. The decompression tank 31 may be provided so as to surround the drying nozzle block 32. The decompression tank 31 has an open top. A drain port (not shown) may be provided at the bottom of the drying tank 31. The drying tank 31 is connected to the decompression device. In this case, the grip portion 48 is provided with a cover so as to close the opening of the work W when the work W is inserted into the decompression tank 31.

  The work transfer device 40 is installed behind the cleaning nozzle block 22 and the drying nozzle block 32. Specifically, the work transfer device 40 is near the position on the vertical bisector of a line segment connecting the center of the cleaning nozzle block 22 and the center of the drying nozzle block 32 in plan view, and is located rearward from the line segment. It is installed at a remote location.

  A control device 91 is arranged inside the outer cover 11, here in the supply device 90. The operation of each part of the cleaning device 1 is controlled by the control device 91. The control device 91 is a computer that controls the operation of each part of the cleaning device 1 by the CPU executing a program stored in advance in the storage means.

Next, a method of cleaning the work W using the cleaning apparatus 1 of this embodiment will be described mainly with reference to FIG. The operation of the cleaning device 1 is controlled by the control device 91.
First, the unwashed work W (see FIG. 2) is placed on the work support 16 (see FIG. 2) by an operator or the like, and is supported by the work support 16. Then, the slide door 13 is opened.

  The work transfer device 40 rotates the main body tower 50 and expands and contracts in the vertical direction, and the operation of each part of the arm 42 (hereinafter, also simply referred to as “operation of the main body tower 50 and the arm 42”). 44 is moved onto the work support 16 through the carry-in port 12. Here, the arm 42 is opened and closed by rotating the first arm portion 45 around the rotation axis L2. Further, by rotating the second arm portion 46 around the longitudinal axis L3, the posture of the hand portion 47 changes in a plane perpendicular to the longitudinal axis L3. Further, by rotating the hand portion 47 around the rotation axis L4, the posture of the hand portion 47 changes within a plane perpendicular to the rotation axis L4. Further, the rotation of the tip portion 44 about the longitudinal axis L5 causes the gripping device 48 attached to the tip portion 44 to rotate in a plane perpendicular to the longitudinal axis L5.

  Subsequently, the work transfer device 40 holds the work W by the holding device 48, carries the work W into the cleaning chamber 20, and positions the work W directly above the cleaning tank 21. Then, the slide door 13 is closed. In this state, the cover 61 partitions the cleaning chamber 20 and the drying chamber 30. That is, the washing chamber 20 and the drying chamber 30 are in a state of being partitioned from each other by the partition plate 80 and the cover 61.

  The gap formed between the cleaning chamber 20 and the drying chamber 30 during cleaning and drying of the work W is, for example, whether an auxiliary partition plate is attached or a part of the edge of the partition plate 80 is expanded. Then, it is preferable to cover as much as possible. In addition, a slight gap between the cover 61 and the edge of the partition plate 80 necessary for turning the main body tower 50 and the cover 61 has a flexible rubber plate, a brush, or the like at the edge of the partition plate 80. It can be closed by attaching an auxiliary member.

Subsequently, the supply device 90 operates to supply the cleaning liquid to the cleaning nozzle 23. The work transfer device 40 puts the gripped work W into the cleaning tank 21 and cleans the work W. That is, the cleaning liquid is sprayed from the cleaning nozzle 23 onto the work W, and chips and oils and fats are washed away from the work W by the cleaning liquid. At the time of cleaning, the work transfer device 40 adjusts the position of the jet of the cleaning liquid that hits the work W by the operation of the main body tower 50 and the arm 42. In this way, the work W is cleaned in the cleaning chamber 20. Then, when the predetermined time has elapsed, the injection of the cleaning liquid by the cleaning nozzle 23 is stopped, and the cleaning of the work W is completed.
In this state, the cover 61 partitions the cleaning chamber 20 and the drying chamber 30. That is, the washing chamber 20 and the drying chamber 30 are in a state of being partitioned from each other by the partition plate 80 and the cover 61. The work transfer device 40 may move the work W in the cleaning nozzle block 22 in the horizontal direction. Even in this case, since the side surface 62 is a cylindrical surface, the side surface 62 and the partition plate 80 keep the partition between the cleaning chamber 20 and the drying chamber 30.

  Subsequently, the work transfer device 40 carries the cleaned work W into the drying chamber 30 by the operations of the main body tower 50 and the arm 42, and positions it above the drying nozzle block 32. In this state, the cover 61 partitions the cleaning chamber 20 and the drying chamber 30. That is, the washing chamber 20 and the drying chamber 30 are in a state of being partitioned from each other by the partition plate 80 and the cover 61.

  Here, when the main body tower 50 turns, the arm 42 is closed and the arm 42 and the work W are housed inside the cover 61. This prevents the arm 42 and the work W from interfering with the partition plate 80.

  Then, dry air for air blowing is supplied to the drying nozzle 33. The work transfer device 40 puts the gripped work W into the drying tank 31, and the work W is dried. That is, dry air is sprayed from the drying nozzle 33 onto the work W, and the work W is dried. At the time of drying, the work transfer device 40 adjusts the position of the jet of dry air that hits the work W by the operation of the main body tower 50 and the arm 42. In this way, the work W is dried in the drying chamber 30. Then, after a lapse of a predetermined time, the ejection of the dry air by the drying nozzle 33 is stopped and the drying of the work W is completed.

  Then, the slide door 15 is opened. The work transfer device 40 moves the dried work W through the carry-out port 14 onto the work support 17 (see FIG. 2) by the operation of the main body tower 50 and the arm 42. The work transfer device 40 releases the grip of the work W by the gripping device 48, and the work W is placed and supported by the work supporting portion 17.

  When the cleaning and drying process of the work W is completed in this way, the work transfer device 40 returns the positions of the main body tower 50 and the arm 42 to the initial state, and the slide door 15 is closed to process the next work W. Prepare The initial state is a state in which the arm 42 is closed and faces the carry-in port 12 here, but the present invention is not limited to this, and, for example, faces the cleaning tank 21 and the drying chamber 30. You may be in a state of being.

  As described above, the cleaning apparatus 1 according to the present embodiment performs the cleaning chamber 20, the drying chamber 30 adjacent to the cleaning chamber 20, and the transfer of the work W from the cleaning chamber 20 to the drying chamber 30. And a work transfer device 40. The work transfer device 40 includes a main body tower 50 rotatable around a vertical axis L1, and a gripping device 48 having a base end portion 43 rotatably connected to the main body tower 50 and a front end portion 44 for gripping a work W. It has an attached arm 42. A cover 61 for partitioning the cleaning chamber 20 and the drying chamber 30 when cleaning and drying the work W is attached to the main body tower 50.

With such a configuration, the work transfer device 40 can transfer the cleaning chamber 20 to the drying chamber 30 even in a small space by rotating the main body tower 50 and opening / closing the arm 42. Further, since the cover 61 attached to the main body tower 50 separates the cleaning chamber 20 and the drying chamber 30 during cleaning and drying of the work W, it is possible to suppress the diffusion of the cleaning liquid droplets.
That is, according to the present embodiment, it is possible to provide the cleaning device 1 that can reduce the area occupied by the entire device while suppressing the diffusion of the spray of the cleaning liquid.

  Further, in the present embodiment, the work transfer device 40 further carries in the work W into the cleaning chamber 20 and carries out the work W from the drying chamber 30. With such a configuration, the work transfer device 40 can carry in and out the work W even in a small space by turning the main body tower 50 and opening and closing the arm 42.

  Further, in the present embodiment, the work transfer device 40 is installed behind the cleaning nozzle block 22 and the drying nozzle block 32. In such a configuration, the work W can be transferred from the cleaning chamber 20 to the drying chamber 30 by rotating the main body tower 50 at a relatively small angle within a range of 45 to 120 degrees, for example. Therefore, the transfer time of the work W from the cleaning chamber 20 to the drying chamber 30 can be shortened. The work transfer device 40 may be installed in front of the cleaning nozzle block 22 and the drying nozzle block 32.

  In addition, the present embodiment includes a partition plate 80 installed between the cleaning chamber 20 and the drying chamber 30, and the partition plate 80 has the cover 61 when the work W is transported from the cleaning chamber 20 to the drying chamber 30. A partition opening portion 83 that can pass therethrough is formed. In such a configuration, the cleaning chamber 20 and the drying chamber 30 can be partitioned by the partition plate 80 and the rotatable cover 61 that are installed in advance. Further, when the work W is transferred from the cleaning chamber 20 to the drying chamber 30, the cover 61 attached to the main body tower 50 rotates, but since the partition opening 83 is formed, the cover 61 and the partition plate 80 are separated from each other. Do not interfere.

  Further, in the present embodiment, the cover 61 has a cylindrical shape having a side surface 62 facing the edge portion of the partition plate 80 that extends in the up-down direction of the partition opening portion 83. Further, the side surface 62 of the cover 61 is formed with a cover opening 63 through which the arm 42 can pass when the distal end portion 44 of the arm 42 is separated from the vertical axis L1. With such a configuration, the distance between the edge of the partition opening 83 and the side surface 62 of the cover 61 does not change even if the cover 61 rotates. Therefore, the partition plate 80 and the cover 61 can partition the cleaning chamber 20 and the drying chamber 30 more reliably. Further, the work W can be gripped and transported while opening and closing the arm 42 through the cover opening 63 formed on the side surface 62 of the cover 61.
