駆動方式のものを使うことができる。A movable table 1 of a vibrator 15 is provided on a lower surface of the cleaning tank 1.
6 are combined. The vibrator 15 has a configuration in which an electromagnetic solenoid (not shown) is provided on the fixed base 17 and the movable base 16 is connected to the fixed base 17 via a leaf spring. A magnetic plate that is attracted by excitation of the electromagnetic solenoid is fixed to a key point of the movable base 16. When the electromagnetic solenoid is excited, the magnetic base plate is attracted to the movable base 16 by a suction force acting on the magnetic base plate. The rotation in the along direction and the parallel movement in the direction away from the fixed base 17 occur simultaneously. That is, when the electromagnetic solenoid is excited, the movable base 16 moves upward while rotating, and when the electromagnetic solenoid is de-energized, the movable base 16 moves downward while rotating and returns to the original position by the return force of the leaf spring. Return to position. Therefore, the movable base 16 of the vibrator 15 vibrates in the rotational direction and vibrates in the up-down direction due to the excitation / non-excitation of the electromagnetic solenoid. As the vibrator 15,
In addition to the electromagnetic solenoid type described above, a vibration motor having an unbalanced weight, a piezo-vibration type or a cam drive type can be used.

Is activated, the member A to be cleaned at the bottom of the cleaning tank 1 gathers around the divided tanks 2a and 2b and rests on the transport paths 3a and 3b. The member A to be cleaned is carried obliquely upward by rotation by excitation of the solenoid, and when the electromagnetic solenoid is de-energized, the conveying paths 3a and 3b are moved at a speed higher than the falling speed of the member A to be cleaned by the return force of the leaf spring. Then, the member to be cleaned A is returned, and the member to be cleaned A is awaited. By repeating this, the member to be cleaned A can be continuously advanced obliquely upward. here,
Since the transport paths 3a and 3b are cantilevered, the vibrator 1
Due to the vibration of the cleaning tank 1 caused by 5, the transport paths 3 a and 3 b perform a tilting motion, and the cleaning liquid put in the cleaning tank 1 is stirred. If the vibration cycle of the vibrator 15 is set so as to resonate with the cleaning tank 1, the transport path 3a,
A strong water flow is generated from the outer peripheral side to the inner peripheral side of the cleaning tank 1 by the tilting movement of 3b, and the cleaning liquid can be sufficiently brought into contact with the member A to be cleaned, and cleaning can be performed efficiently.

It is put into the outer division tank 2b through the through-hole 4, and the outer division tank 2b is also cleaned while moving up the transport path 3b.
When the member A to be cleaned comes out of the liquid level of the cleaning liquid, the liquid draining section 8 drains the cleaning liquid. Here, the cleaning liquid that has been cleaned is supplied to the outer divided tank 2b, and since there is almost no backflow of the oil from the inner divided tank 2a, most of the oil on the surface of the member A to be cleaned is removed. become. Further, the cleaning liquid is sprayed onto the member A to be cleaned by the cleaning liquid discharge pipe 11, so that the oil slightly remaining on the surface of the member A to be cleaned is also washed away. Thereafter, steam heated by the steam discharge pipe 12 is sprayed on the member A to be cleaned, so that the cleaning liquid and a small amount of oil remaining on the surface of the member A to be cleaned are washed off.
It is dried by the air blown from 3. The dried member to be cleaned A passes through the outlet 5 and is conveyed to the transport path 3
It is taken out from the take-out part 6 which is the upper end of b. As described above, the surface treatment system of the present embodiment can continuously clean and further dry the cleaning target member A as the processing target. Here, in the present embodiment, the division bath 2a, the surface treatment step of performing the surface treatment (cleaning treatment) is performed.
2b is used in a washing step of washing the adhered substance remaining on the surface of the object after the surface treatment with water and a drying step of drying moisture remaining on the surface of the object after the washing step. The division tank 2b is shared.

保つことができるのである。In the present embodiment, a closed system is configured so as to reduce the amount of the cleaning liquid discharged to the outside. That is, the cleaning liquid containing a large amount of oil that has passed through the overflow path 7 is introduced into the primary separation tank 21, and the oil and the cleaning liquid are separated by the baffle plate 22 provided in the primary separation tank 21. The separated oil is treated as waste oil.
Further, the cleaning liquid that has passed through the primary separation tank 21 is further introduced into the secondary separation tank 23, and the oil component and the cleaning liquid are further separated by the baffle 24. The washing liquid from which the oil has been separated in the separation tanks in a plurality of stages is pumped out by the pump 25 and introduced into the management tank 26. In the management tank 26,
A liquid level sensor 27 is provided to manage the cleaning water so as to maintain a constant amount, and a heater 28 is provided to control the temperature. Since a part of the cleaning liquid is discarded and reduced together with the oil, the cleaning liquid is replenished from the replenishing liquid tank 30 by controlling the valve 29. The cleaning liquid in the management tank 26 is pumped out by the pump 31 and introduced into the divided tank 2b through the cleaning liquid discharge pipe 11. Here, the dividing tank 2b
The opening amount of the control valve 32 provided in the vicinity of the cleaning liquid discharge pipe 11 is adjusted so that the liquid level of the cleaning liquid in (2) is slightly higher than the liquid level of the cleaning liquid in the divided tank 2a (near the height position of the overflow path 7). I do. In this manner, the cleaning liquid is introduced into the division tank 2b, and the cleaning liquid is taken out from the division tank 2a through the overflow path 7, so that a flow from the division tank 2b to the division tank 2a is formed in the through-hole 4, and the division tank 2a is formed. The separated oil does not flow into the divided tank 2b, and the cleaning liquid in the divided tank 2b can be kept more clean than the cleaning liquid in the divided tank 2a.

いる。As described above, in the surface treatment system of the present embodiment, the washing tank 1 and the washing tank 40 are
The member to be cleaned A
Can be continuously washed, and the installation area can be reduced. (Embodiment 3) In this embodiment, as shown in FIGS. 4 and 5, the member A to be cleaned introduced through the through-hole 4 in the outer dividing tank 2b is divided by the slope 19 into the dividing tank 2b.
Is to be guided downward. That is, the slope 19 is inclined downward while spirally wrapping around the peripheral wall between the inner and outer divided tanks 2a and 2b. Rather than reaching the lower part of the dividing tank 2b in time, it reaches the lower part of the dividing tank 2b along the slope 19 for a relatively long time.

Can greatly increase the contact time with the washing liquid, and the possibility of separating even firmly adhering oil increases. In addition, as a place where the slope 19 is provided, a space which is inevitably formed for introducing the member A to be cleaned between the peripheral wall between the two separation tanks 2a and 2b and the transport path 3b can be used. From the transport path 3a,
The cleaning capacity can be increased without increasing the number of circulations of 3b and increasing the height of the cleaning tank 1 or increasing the volume of the cleaning tank 1. That is, the space in which the slope 19 is provided is a dead space that is hardly used except for the area below the through-hole 4, so that the internal space of the cleaning tank 1 is effectively used.
