  The two types of packing (water-absorbent packing 1 and sealing-only packing 2) shown in FIGS. 1-1 to 3 will be described. The water-absorbing packing 1 (packing 1) is a water-absorbing resin material, It has elasticity. In the embodiment, since two types of packings (packings of a double structure) are used, they are classified by color, and are made white in consideration of distinction and easy handling. The divided ring pieces are joined to form an annular shape (see FIG. 1-2). In this example, as will be described later, two types of packings are provided at a plurality of locations including the joint 100 on the outer side 10-1 of the movable washer 10, which will be described later, slightly above the opening 1001. It is screwed at a plurality of locations on the second flange 1000. The purpose of screwing at a plurality of locations is to prevent the two types of packing from sagging and to securely attach the two types of packing. A plurality of first counterbore holes 101 and fine holes 101a are formed in the packing 1. The head side 300 of the stopper 3 is inserted into the counterbore holes 101, and the fine holes of the counterbore holes 101 are formed. The shaft portion 301 of the stopper 3 is inserted into 101a. Next, the sealing packing 2 (referred to as packing 2) is a water-sealing resin material and has elasticity. In the embodiment, since two types of packing are used, they are classified into different colors, and are set to black in consideration of simplification and easy handling. A plurality of second counterbore holes 201 are formed in the packing 2, a washer 302 fitted into the stopper 3 is inserted into the counterbore hole 201, and a shaft of the stopper 3 is inserted into the counterbore hole 201. This is a structure in which the portion 301 is also inserted.

  Further, a first flange side 1100 provided around the fixed washer 11 to which two types of packings are pressed is provided on the outer side 11-1 of the fixed washer 11 and below the opening 1101. In this example, the first flange side 1100 is attached using the third flange side 1102 which is the outer side 11-1 and is further provided below the opening 1101. The first flange side 1100 includes a main body 1100a and a wall piece 1100b erected around an end of the main body 1100a. The side width 1100c is wider than the two types of packings (the width is the width of the main body 1100a and the dimension “outward in the radial direction” outside the outer side 11-1). In addition, the width of the two types of packings in the main body 1100a (the width orthogonal to the thickness (eg, the width in the left-right direction X in FIG. 3)) or the width of the second outer ring side of the second flange side 1000 A plurality of pores 1103 for discharging the squeezed fluid are provided in the outer ring side portion that is wider. The fixed washer 11 may have a cylindrical shape as shown in FIGS. 4-1 to 6-2 and a structure having a hemisphere as shown in FIGS. 7-1 and 7-2.

  The two types of packings are screws on the outer side 10-1 of the movable cleaning device 10 having a hemispherical shape (semi-cupped shape) and on the lower side of the second flange side 1000 provided slightly above the opening 1001. Stop it. This structure will be described with reference to FIG. 3. The second flange side 1000 is a spherical surface above the opening 1001, and is formed so as to bulge in the radial direction of the entire outer peripheral surface 1001a. ing. Therefore, the packing 2 is attached to the lower side of the second flange side 1000, the packing 1 is attached to the lower side of the packing 2, and the packing 2 and the inner peripheral portions 2a, 1a of the packing 1 are opened. It reaches inside the wall thickness 1001b of the part 1001 (covers the wall thickness 1001b). In this state, the shaft portion 301 of the stopper 3 is moved from the counterbore hole 101 of the packing 1 and the fine hole 101a (through the packing 1), and passes through the counterbore hole 201 of the packing 2 and the fine hole 201a. (Through the packing 2) and inserted into a plurality of holes 1000a (corresponding to the packings 1.2 of φ300 and 16 holes) formed in the second flange side 1000. By tightening the nut 303 to the screw 300a (shaft portion 301) of the inserted stopper 3, the packings 1 and 2 are supported (screwed) under the second flange side 1000 in a tensioned state. The packings 1 and 2 do not drop. For example, there is no droop between the stops 3,3.

  The two types of packings are compressed when the movable washer 10 is combined with the fixed washer 11, thereby sealing (sealing) respective openings described later, and shuts off the washing chamber D from the outside. At the time of this uniting and sealing, the work W is washed by jetting a fluid from a fluid nozzle described later, and dried by jetting air at the end of the washing. Thereafter, when the movable washer 10 moves or moves up, it is separated from the fixed washer 11 and the opening 1100 of the fixed washer 11 is opened. At this time, if a fluid remains on the ceiling surface 1002 of the movable washer 10 and / or the conventional packing, the fluid may drop when the movable or ascending device is moved or ascends. Work and the like are required, causing a problem. In the present invention, the residual fluid of the two types of packings (mainly packing 1) is received by the first flange side 1100 by compression of the two types of packings, and then flows out of the machine through the plurality of pores 1103 ( It flows down).

  The movable washer 10 exhibiting a hemisphere has a structure in which the movable washer 10 is combined with a fixed washer 11 to be described later in a rocking manner (the structure in FIGS. 4 to 6) and a structure in which the movable washer 10 is combined in a vertically movable manner (the structure in FIG. Yes, but in principle the structure is common. Then, the movable cleaning device 10 is combined with the fixed cleaning device 11 to form a closed cleaning chamber D (the state shown in FIGS. 4-1 and 7-1). Further, the movable washer 10 includes a plurality of upper nozzles 12a and 12b for fixed fluid and air shown in FIG. 5-1 or FIG. 7-1 and FIG. The movable nozzles 13a and 13b described later are disposed inside.
