It is installed at a remote location.

The control device 91 is arranged inside the outer cover 11, here, inside 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 device 1 of the present 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 portion 16 (see FIG. 2) by an operator or the like, and is supported by the work support portion 16. Subsequently, the slide door 13 opens.

The work transfer device 40 rotates the main body tower 50, expands and contracts in the vertical direction, and moves each part of the arm 42 (hereinafter, also simply referred to as “movement of the main body tower 50 and the arm 42”), thereby causing a tip portion of the arm 42. 44 is moved onto the work support 16 through the carry-in port 12. Here, the arm 42 opens and closes by rotating the first arm portion 45 around the rotation shaft 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 shaft L4, the posture of the hand portion 47 changes in a plane perpendicular to the rotation shaft L4. Further, by rotating the tip portion 44 around the longitudinal axis L5, the gripping device 48 attached to the tip portion 44 rotates in a plane perpendicular to the longitudinal axis L5.

Subsequently, the work transfer device 40 grips the work W by the gripping device 48, carries it into the cleaning chamber 20, and positions it directly above the cleaning tank 21. After that, the slide door 13 is closed. In this state, the cover 61 separates the washing 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. Therefore, it is preferable to cover as much as possible. Further, the slight gap between the cover 61 and the edge of the partition plate 80, which is necessary for turning the main body tower 50 and the cover 61, is a rubber plate, a brush, or the like having flexibility 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 washed in the washing chamber 20. Then, when the predetermined time elapses, 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 separates the washing 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 horizontally in the cleaning nozzle block 22. Even in this case, since the side surface 62 is a cylindrical surface, the cleaning chamber 20 and the drying chamber 30 are kept separated by the side surface 62 and the partition plate 80.

Subsequently, the work transfer device 40 carries the cleaned work W into the drying chamber 30 by the operation of the main body tower 50 and the arm 42, and positions the work W directly above the drying nozzle block 32. In this state, the cover 61 separates the washing 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 is turned, 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.

Subsequently, 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 ejected from the drying nozzle 33 to the work W to dry the work W. 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, when the predetermined time elapses, the injection of the dry air by the drying nozzle 33 is stopped, and the drying of the work W is completed.

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

When the cleaning and drying processing of the work W is completed in this way, the work transport device 40 returns the positions of the main body tower 50 and the arm 42 to the initial state, the slide door 15 is closed, and the processing of the next work W is started. Be prepared. In the initial state, the arm 42 is closed and faces the carry-in inlet 12, but the initial state is not limited to this, and for example, the arm 42 faces the washing tank 21 and the drying chamber 30.
