BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger device for a plating apparatus suitable for use in a circulation plating apparatus.

[0002]

2. Description of the Related Art A circulating plating apparatus is an apparatus that performs a plating process while suspending a hanging jig holding a work on a hanger and moving it along a circulation line. Generally, this hanger has a structure that cannot be rotated with respect to the traveling frame that travels on the circulation rail, so that attachment / detachment and inspection of the work can be performed only from the side of the hanger facing the outside of the circulation line, and There is a drawback that both sides cannot be used.

Accordingly, the present applicant has developed a hanger apparatus for a plating apparatus in which a hanger can be rotated by a friction clamp, and has already registered a utility model No. 1835171 (Jitsuho 2-
No. 7878). As shown in FIG. 3, a vertical shaft 52 is supported on a hanger bearing 51, and a bar hanger 53 for hanging a hanging jig is attached to the lower end thereof. The vertical shaft 52 and the bar-shaped hanger 53 can be stopped at a specific angular position by providing an end face of the flange member 54 with a friction clamp 55.

In the apparatus shown in FIG. 3, the vertical shaft 52 and the bar-shaped hanger 53 can be turned over against the friction clamp 55 at the work attaching / detaching position or the inspection position. There is an advantage that the work can be handled. However, since the bar hanger 53 is fixed to the vertical shaft 52 in this prior application, the bar hanger is
There was a problem that 53 could not be transferred to another line by an automatic machine. Further, since the entire hanger bearing 51, the vertical shaft 52, and the bar-shaped hanger 53 are on the minus side, there is no problem in the plating of a normal work, but it cannot be used in the plating of a work requiring an auxiliary electrode. There was a problem.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and enables the transfer of the hanger without losing the advantage of the prior invention that the hanger can be rotated. The purpose of the present invention is to provide a hanger device of a plating apparatus that enables the use of electrodes.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to support a vertical shaft via a clamp mechanism which can be stopped at a specific angular position on a hanger bearing, and to provide a lower end of the vertical shaft. In addition, a gate-shaped arm having the ends of both arms as hanger support portions having a mountain cross section, and a contact portion for elastically receiving the auxiliary pole of the hanger and supplying auxiliary power are provided between the two arms. It is assumed that.

[0007]

The hanger device of the plating apparatus according to the present invention is used by engaging a hanger with a hanger support portion of a portal arm at the lower end of a vertical shaft, and the vertical shaft can be stopped at a specific angular position. Since the hanger is supported by the hanger bearing via the clamp mechanism, the hanger can be inverted at the work attaching / detaching position or the inspection position. Further, since the hanger is engaged with the hanger support of the portal arm, it can be transferred to another line by a transfer means such as a robot. Further, since the contact portion is provided between the two arms, the auxiliary pole of the hanger can be elastically received by the contact portion to supply the auxiliary power, and a more complicated work plating can be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. In FIG. 1, 1 is a plating tank, 2 is a circulating running rail provided on the side thereof, 3 is a running frame running on the circulating running rail 2, and 4 is attached to the running frame to perform a vertical movement. Lifting frame,
Reference numeral 5 denotes a horizontal arm extending from the lifting frame 4 onto the plating tank 1, and reference numeral 6 denotes a hanger bearing at the tip.

As shown in FIG. 2, a vertical shaft 7 is supported on the hanger bearing 6, and a portal arm 8 is attached to a lower end of the vertical shaft 7. A non-circular flange member 9 is fixed to the upper end of the vertical shaft 7.
A friction-type clamp mechanism 10 such as a ball spring provided on the upper surface of the distal end portion can contact the end surface of the flange member 9. The vertical shaft 7 is stably stopped at the angular position shown in FIG. 2 by the clamp mechanism 10. However, if an external force is applied, the vertical shaft 7 can be rotated with respect to the hanger bearing 6.

The distal ends of the two arms 11 of the portal arm 8 form a hanger support 12 having a mountain-shaped cross section. As shown in FIG. 2, these hanger support portions 12 are engaged with inverted V-shaped receiving portions 14 abutting on both sides of the hanger 13, and
13 can be stably held. In addition to the portal arm 8 at the lower end of the vertical shaft 7, an auxiliary pole arm 15 is provided in the middle of the two arms 11, and a contact portion 16 made of a Z-shaped spring is provided at the lower end. The contact portion 16 is for elastically receiving the tip of an auxiliary pole 17 provided at the center of the hanger 13 in an insulated state with respect to the hanger 13 to supply auxiliary power. These portal arm 8 and auxiliary pole arm
Reference numeral 15 denotes a member which is rotated integrally with the vertical shaft 7. The work is hung on a hanging jig (not shown), and the work is plated by hanging the hanging jig on the hanger 13.

As shown in FIG. 1, power supply cables 17 and 18 are provided on the lower surface of the horizontal arm 5, and the hanger bearing 6, the portal arm 8, and the hanger 13 supported by the power supply cable 17 via the power supply cable 17. Is connected to the negative pole of the DC power supply to energize. On the other hand, a knife-like switch 19 is provided at the end of the power supply cable 18, and when the portal arm 8 is at the angular position in FIG. 2, the rear end of the auxiliary pole arm 15 is connected to the knife-like switch 19. The auxiliary pole arm 15 is connected to the positive pole of the DC power supply and can be energized. Therefore, when the vertical shaft 7 is rotated from the position shown in FIGS. 1 and 2, the auxiliary pole arm 15 is disengaged from the knife-like switch 19, so that no power is supplied.

In the apparatus of the embodiment configured as described above, a hanging jig (not shown) is hooked on the hanger 13, and the hanger 13 is stably held on the hanger support portion 12 having the cross section of the gate-shaped arm 8. It is used at this time, hanger 13
Is on the minus side, the auxiliary pole 17 of the hanger 13 is on the plus side, and auxiliary power is supplied. This hanger 13 is moved up and down while sequentially moving on the circulation line like a conventional one,
A plating process or the like is performed, but uniform plating can be performed even on a work having a complicated shape by the action of the auxiliary pole 17.

As described above, since the vertical shaft 7 is stably held at the illustrated angular position by the clamp mechanism 10, the hanger 13 does not rotate while the hanger 13 moves on the circulation line. However, if an external force is applied at the work attachment / detachment position or the inspection position, the hanger 13 can be easily inverted, so that both surfaces of the hanger 13 can be used effectively. Further, since the hanger 13 is only supported by the hanger support portion 12 of the portal arm 8, it can be easily moved to another line by a robot or the like.

[0014]

As described in detail above, the hanger device of the plating apparatus of the present invention can rotate the hanger at the work attaching / detaching position, the inspection position, etc., and can change the hanger. Further, there is an advantage that a plating process using the auxiliary electrode can be performed. Therefore, the present invention has a very high practical value as a solution to the conventional problems.
