A pusher 403 for contacting and pushing is provided with a fixed moving block 420.

The first pusher means as described above causes the pusher 403 to pull and move the hanger bracket 600 when the rack member 401 linearly moves by the rotation of the pinion gear 401.

5C and 8, the surface treatment tank 500 is formed long in the moving direction of the object 10.

In addition, the to-be-processed object 10 is provided along the longitudinal direction of the surface treatment tank 500 in the same line as the first horizontal guide bar 100 at the lower position obtained in the surface treatment tank 500. A second horizontal guide bar 110 to guide the hanger bracket 600 is installed, and is provided in parallel with the second horizontal guide bar 110 is provided with a chain 620 is rotated by the power of the motor.

The hanger bracket 600 is coupled to the chain 620 is coupled to the sprocket 603 to be pulled in accordance with the rotation of the chain 620.

In addition, a second pusher means for moving the hanger bracket 600 from the first horizontal guide bar 100 to the second horizontal guide bar 110 is provided.

The second pusher means may push the hanger bracket 600 positioned on the first horizontal guide bar 100 by a cylinder (not shown) to move to the second horizontal guide bar 110.

The guide device configured as described above is operated as follows.

First, as illustrated in FIGS. 5A, 5B, and 6, the workpiece 10 is clamped vertically to the clamp 610 of the hanger bracket 600, and thus, the first horizontal guide rod ( Is moved to the right along 100).

At this time, as shown in Figure 7a, as the pusher motor 400 is operated to rotate the pinion gear 401, the rack member 402 is moved linearly while the pusher 403 is towing while hanging the hanger bracket 600. As illustrated in FIG. 7A, the object 10 is guided and entered between the first and second horizontal guide rods 321 and 322 of the guide body 300.

On the other hand, as shown in Figure 5c, when the hanger bracket 600 is in contact with the stopper 220 at the time when the object to be processed 10 enters the guide body 300, the stopper 220 rotates the pusher motor Stop the operation of 400.

Subsequently, the lifting motor 211 is operated to rotate the screw rod 210 so that the first horizontal guide bar 100 is lowered. In this case, as shown in FIGS. 5C and 7B, the hanger bracket 600 clamping the object 10 and the lifting bracket 350 pulling the guide body 300 are lowered together.

At this time, even if the object 10 is to be bent by the resistance when it is obtained from the surface of the treatment liquid in the surface treatment tank 500, it is possible to prevent the phenomenon that is supported by the guide body 300 to bend.

As such, when the object 10 and the guide body 300 are stably obtained into the surface treatment tank 500, the hanger is mounted by a second pusher (a cylinder not shown) as shown in FIGS. 5C and 8. The bracket 600 is moved from the first horizontal guide bar 100 to the second horizontal guide bar 110.

As such, the hanger bracket 600 moved to the second horizontal guide bar 110 is horizontally moved along the second horizontal guide bar 110 by the driving of the chain 620 and is treated in the surface treatment tank 500. The surface treatment of the to-be-processed object 10 is performed with a liquid.

After the hanger bracket 600 is moved to the second horizontal guide bar 110, the lifting motor 211 is operated by the detection of a sensor (not shown), so that the first horizontal guide bar 100 and the guide body 300 are moved. Raise the) to guide the next workpiece.

The guide device having the above configuration lifts the first horizontal guide bar 100 and the guide body 300 to prevent deformation when the object 10 is received in the treatment liquid.

In particular, since the guide body 300 has a structure including the first and second horizontal guide rods 321 and 322 integrated by the curved rod 313, the structure is simple.

That is, as shown in Figure 4, conventionally, the movable member 55 for holding the object to be processed is composed of separate holding pieces 57, and also a separate drive cylinder for moving the holding pieces (57) ( 68) it is possible to solve the problem of complicated structure and high installation cost.

In addition, by having the first horizontal guide bar 100 and the second horizontal guide bar 110, which is elevated, the other to-be-processed object 10 is surface-treated in the surface treatment tank 500. Since the 10 can be continuously supplied through the first horizontal guide bar 100, the working time can be shortened.
