DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show an embodiment of a work transfer hanger according to the present invention. In this embodiment, a vehicle body 10 shown in FIG.
It is operated when it is sequentially transported to the immersion tank 12, the immersion tank 13, the immersion tank 14, and the spray tank 15.

A guide rail 16 is provided above each of the equipments 11 to 15 along a coating line. The hanger 20 of this embodiment is suspended from the guide rail 16.

As shown in FIG. 1, the hanger 20 comprises a moving vehicle 200 and a holder 201.

The moving vehicle 200 has an upper frame 203 and a lower frame 204 connected by two rods 202.
Are protruded from each other. Each arm 205 is provided with a wheel 206 on the upper surface thereof in contact with the upper surface of the guide rail 16, and one arm 205 is provided with a motor 207 for driving the wheel 206.

As shown in FIG. 2, a pair of winches 208 is attached to the lower surface of the upper frame 203. Then, the wire 2 wound around these winches 208
The leading end of 09 extends from the front center and the rear center of the lower frame 204 to the lower surface side of the frame 204 via pulleys 210, 211 and 212, respectively.

The holder 201 includes a support frame 213,
It is attached between four rods 214 each having an upper end attached to the square of the support frame 213 and two rods 214 arranged side by side at an interval in the front-rear direction (the direction perpendicular to the plane of FIG. 1). Pair of body mounting tables 215
And

The upper end of each rod 214 is pivotally supported about an axis L1 parallel to the guide rail 16, and the base 215 is also pivoted about a similar axis L2. Supported. Therefore, the pair of rods 214 and the support frame 213 in FIG. 2 constitute a parallel link.

As shown in FIG. 3, the support frame 213 is formed of a rectangular frame, and brackets 221 are fixed to the outer surfaces of both longitudinal frame members 213a at predetermined intervals. The upper ends of the link rods 220 are pivotally supported on the individual brackets 221 via pins 222, and the lower ends of the link rods 220 are connected via pins 223 to the longitudinal beam members 2 of the oil pan 219.
19a. Note that the arrangement interval of the pins 223 is the same as that of the pins 222 described above.

Therefore, the support frame 213, the link rod 220, and the beam member 219a form a parallel link.

The hanger 20 constructed as described above moves along the guide rail 16 by operating the traveling motor 207 shown in FIG. When the support frame 213 is positioned horizontally as shown in FIG. 2, the oil pan 219 is positioned horizontally so as to cover the upper surface of the body 10.

Here, each winch 208 is connected to a wire 209.
When the holder 201 is operated in a direction in which the holder 201 is extended, the holder 201 can be lowered as shown in FIG. At this time, by changing the wire feeding amount of each winch, the support frame 213 is inclined as shown in the figure, and accordingly, the body mounting table 215 is also inclined.

When the support frame 213 is inclined,
By the action of the parallel link composed of the support frame 213, the link rod 220, and the oil pan 219, the oil pan 2
19 slides rightward in FIG. 5 while maintaining the parallel state with the support frame 213.

Now, assuming that the oil pan 219 is rigidly connected to the support frame 213, similarly to the conventional hanger shown in FIG. 11, the oil pan 219 is placed at the position shown by the broken line in FIG. Will be. As is clear from the comparison between the oil pan 219 shown by the broken line and the oil pan 219 shown by the solid line, according to the above embodiment, the oil pan 219 can be shifted by the horizontal distance L. In other words, the relative positional relationship between the oil pan 219 and the body 10 is kept constant regardless of the inclination angle of the support frame 213. Therefore, even when the body 10 is inclined, falling objects such as water droplets can be reliably received by the oil pan 219.

In the state shown in FIG. 1 in which the holder 201 has been raised to the uppermost position, the pin 216 provided on the top of the rod 214 is fitted into the cylindrical body 217 provided on the lower surface of the lower frame 204. Thereby, the holder 201 is fixed to the mobile vehicle 200. The cable 218 shown in FIGS. 2 and 4 is provided for grounding the body 10.

Next, another embodiment of the present invention will be described with reference to FIG.

In the holder 201 'of this embodiment, an oil pan 219' is suspended between the upper ends of the rods 214. Note that the pair of rods 214 located on the longitudinal side of the oil pan 219 'corresponds to the pair of rods 214 shown in FIG. A pair of L-shaped brackets 224 project from one and the other longitudinal side surfaces of the oil pan 219 '. The bases of these brackets 224 are connected to the oil pan 219 'by pins 225, and are therefore rotatable about the pins 225. On the other hand, the protruding portion of the bracket 224 has an elongated hole 224.
a is formed, and the rod 214 is
4a through a pin 226 penetrating therethrough.
4.

In this embodiment, the support frame 213, the upper end of the rod 214 and the oil pan constitute a parallel link. That is, the upper end of the rod 214 corresponds to the link rod 220 shown in FIG. Accordingly, when the support frame 213 is inclined as shown in FIG. 7, the oil pan 219 'slides rightward in FIG. 7 while maintaining the parallel state with the support frame 213, and as a result, the same as in the previous embodiment. In addition, the relative positional relationship between the oil pan 219 'and the body 10 is kept constant regardless of the inclination angle of the support frame 213. The broken line in FIG.
9 shows the position of the oil pan 219 'when it is assumed that 9' is rigidly connected to the support frame 213.

The elongated hole 224a is provided for the following reason. That is, a pair of rods 21 shown in FIG.
4 need to be turned around the shaft 228 in directions away from each other for loading and unloading the body 10. If the elongated hole 224a is provided, the pin 226 in FIG. 6 moves along the elongated hole 224a when the rod 214 rotates, so that the rotating operation can be freely performed.

In each of the above embodiments, the support frame 213 is inclined in the direction in which the body 10 is pitched. However, the present invention can be applied to the case where the support frame 213 is inclined in the direction in which the body 10 is rolled. It is.
In this case, the shaft 228 and the oil pan 219 shown in FIG.
A link rod 220 as shown in FIG. 3 may be interposed between the so-called support frame 213 and the oil pan 219.

The body 10 held by the hanger 20 of the above embodiment is moved to a position above the spray tank 11 shown in FIG. 8, and then lowered into the spray tank 11 to be washed with water.

Next, after being raised to above the spray tank 11, it is moved to above the immersion tank 12. And it is immersed in this tank 12 in the mode shown in FIG.

That is, the body 10 is immersed in the tank 12 with the rear side lowered, and the body 10 is rocked in the tank 12. Thereafter, the body 10 is raised with the rear side lowered, and returned to the horizontal posture again.

In the immersion tank 12, processes such as water washing and surface adjustment are performed.

The immersion tank 13 in the next step is provided with a guide rail 16
Has a continuous tank structure in which the width in the longitudinal direction is set to about three times that of the other immersion tanks 12, 14. The posture of the body 10 is also changed in the immersion tank 13 in the same manner as described above, but the immersed body 10 is laterally moved in the tank 15. Therefore, a longer time treatment is performed in the tank 13. In this tank 13, processes such as degreasing, chemical conversion, and electrodeposition are performed.

Next, the immersion tank 14 and the spray tank 15
The body 10 is then carried out to the next step.

The rocking of the body 10 in the tanks 12, 13 and 14 is carried out in order to remove air pockets formed on the surface of the body 10 and eliminate unprocessed portions.
In this embodiment, the body 10 has a swing angle of 10 ° to 17 °.
Is swinging. This swing is performed by alternately driving the winches 208 shown in FIG. 2 in different directions.

Further, the rear side of the body 10 is lowered when the body 10 enters and leaves the tanks 12 to 14 for the purpose of easily and rationally entering and leaving the tank. It is.

That is, since the rear side has many openings,
By lowering the rear side and entering the tank, the processing liquid enters the body 10 more quickly, thereby enabling a smoother tank entry. Also, by lowering the rear side and discharging the processing liquid, the processing liquid from the inside of the body 10 is promptly removed, whereby the amount of the processing liquid carried out can be reduced and the processing liquid can be discharged smoothly.

At the time of entering the tank, the body 10 is lowered at a high speed until landing, and at a low speed until water enters. Then, it is lowered at a medium speed until it is completely sunk, and the above-described swinging is performed at the lower end.

The present invention can be effectively applied to a process other than the painting process, for example, the transfer of a work in a plating process.
