Description

[Detailed Description of the Invention] The present invention relates to an apparatus for moving an electrolytic frame set in a treatment tank in a metal surface treatment apparatus for alumite processing, etc.

In alumite processing, it is necessary to clean after the alumite treatment, and conventionally, an electrolytic frame is set in a water tank and the treated material is immersed in the water tank, and the electrolytic frame is moved vertically to immerse the treated material in the water tank. Clean by moving it up and down.

However, simply moving the treatment material up and down in the water tank does not provide a sufficient cleaning effect.

The present invention was developed in view of the above circumstances, and its purpose is to provide an electrolytic frame moving device for metal surface treatment equipment that allows the electrolytic frame to be moved diagonally up and down while the electrolytic frame is set in the processing tank. It is to provide.

Embodiments of the present invention will be described below with reference to the drawings.

A water tank 1 serving as a treatment tank contains water 2 serving as a treatment liquid, and a pair of upwardly U-shaped pedestals 3 are provided at the upper part of the side wall 1a, and each pedestal 3 is connected to a moving mechanism A. The ends of the pair of electrolytic frames 4 are placed on the electrolytic frames 4.
Set and support in tank 1. Although not shown, the pedestal 3 is also provided on the opposite side wall, and the electrolytic frame 4
are placed on a pair of pedestals 3.

A processing material 6 is suspended from the electrolytic frame 4 via a jig 5, and when the electrolytic frame 4 is placed on the pedestal 3, the processing material 6 is immersed in water 2. The electrolytic frame 4 is lifted upward by a crane or the like (not shown) and transported toward another processing tank.

The moving mechanism A is constructed as follows.
In other words, the pedestal 3 has a plate shape with an upward recess 3a, and one end of the pair of first links 7, 7 is supported by a pin 8 so as to be vertically movable, and the pair of second links 9, 9 are vertically movable. One end is vertically movably supported by a pin 10, the other end of the pair of first links 7, 7 is vertically movably connected to a block 11 fixed to the side wall 1a by a pin 12, and a pair of second links The other ends of 9 and 9 are connected to the block 11 with a pin 13 so as to be movable up and down, forming a parallel four-bar linkage mechanism 14;
The pedestal 3 is tilted and supported so as to be movable in parallel in the vertical direction.

One end of a connecting rod 23 is pivotally connected to the pin 10,
The other end of the connecting rod 23 is pivotally connected to an eccentric pin 22 of a gear 21 fixed to a rotating shaft 19. The rotating shaft 19 is rotatably supported by a pair of brackets 18, and one of the rotating shafts is The shaft 19 is equipped with a pulley 20, which is connected via a belt 17 to a pulley 16 provided on the output shaft 15a of the motor 15, and each gear 21 meshes with the motor 15.
When driven, each rotating shaft 19 rotates.

When the motor 15 is driven to rotate the rotary shaft 19, the eccentric pin 22 rotates around the rotary shaft 19, and the connecting rod 23 moves up and down, so that the pedestal 3 is parallel as shown in FIG. Since the electrolytic frame 4 also maintains its horizontal position and moves diagonally up and down, the processing material 6 is moved up and down in the diagonal up and down direction as shown in FIG. .

Therefore, the treatment material 6 moves up and down while pushing the water 2 laterally, and the cleaning effect becomes sufficient.

Moreover, since the electrolytic frame 4 moves diagonally up and down while maintaining its horizontal position, damage to the jig 5 can be prevented.

Note that the present invention is not limited to cleaning in the water tank 1, and may be used as a device for moving the electrolytic frame 4 diagonally up and down in other processing tanks as well.

The present invention is as described above, and the electrolytic frame 4 has a holder 3
When the rotary shaft 19 is rotated by driving the motor 15 while the rotary shaft 19 is set in the processing tank 1 and supported by 3 moves diagonally up and down while maintaining a parallel attitude, and electrolytic frame 4 also maintains a horizontal attitude and moves up and down in an oblique up and down direction.
The processing material 6 is moved diagonally upward and downward.

Therefore, the treatment material 6 moves up and down while pushing the water 2 in the lateral direction, and the cleaning effect becomes sufficient.

Further, the pedestal 3 is supported on the side wall by a parallel four-bar link mechanism 14, and the connecting rod 23 pivotally connected to the pedestal 3 is pivotally connected to the eccentric pin 22 of the gear 21, and the rotating shaft 19 of the gear 21 is connected to the motor. 15, the structure is simple.

In addition, the pedestal 3 has an upward U-shape, and the electrolytic frame 4
By moving it up and down, you can support it on the pedestal 3,
Since it can be removed, the electrolytic frame 4 can be easily supported on the pedestal 3 or removed by lifting it with a crane or the like.
