Abstract

PROBLEM TO BE SOLVED: To provide a jig inclining mechanism for a plating apparatus of an elevator type capable of executing liquid draining by easily inclining a jig in the respective stop positions of a carrier. SOLUTION: A jig holding arm 10 is freely oscillatably held at the front end of the hanger 5 freely liftably disposed at the traveling carrier 3 and the front end thereof is pressed by utilizing a strap plate 13 disposed in the upper part of the frame in the stop position of the traveling carrier 3, by which the jig 12 is inclined together with a jig holding arm 10. There is no need for installing a cylinder for inclining in each stop position, unlike heretofore, and there is an advantage such that a special control system is not needed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig tilting mechanism in an elevator type plating apparatus.

[0002]

2. Description of the Related Art In an elevator type plating apparatus equipped with a hanger that can be raised and lowered, in order to drain a jig lifted from a plating bath, as shown in FIG. Attach cylinder 22 and hanger
The method of pressing the lower part of the jig 24 lifted from the plating tank 21 by the side from the side surface and inclining the jig 24 to drain the liquid was usual. However, in such a conventional jig tilting device, it is necessary to install the cylinders 22 at each stop position of the carrier 25 that needs draining, and it is necessary to control the driving of a large number of cylinders 22, There is a problem that the control system is complicated and the equipment cost is high.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and eliminates the need to install a cylinder at each stop position of the carrier, and to stop each of the carriers without complicating the control system. The present invention has been made to provide a jig inclining mechanism in an elevator type plating apparatus which can perform liquid drainage by inclining a jig at a position.

[0004]

In order to solve the above-mentioned problems, a jig tilting mechanism in a plating apparatus according to the present invention is provided with a bearing at a tip end of a hanger provided on a traveling carrier so as to be able to move up and down. The jig holding arm whose upper part is bent is swingably supported, and the upper part of the frame at the stop position of the traveling carrier is held down by the upper end of the jig holding arm when the hanger is raised. In addition, a contact plate for inclining the jig is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail. FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a left side view thereof. In these figures, reference numeral 1 denotes a plating tank, and 2 denotes a frame provided on a side of the plating tank 1. Reference numeral 3 denotes traveling carriers which are guided by upper and lower rails 4 and 4 of the frame 2 and travel intermittently by a predetermined distance, and each traveling carrier 3 is provided with a hanger 5 so as to be able to move up and down. Each hanger 5 is provided with a roller 6 on the back surface, and by raising the elevating rail 7 inside the frame 2 while the traveling carrier 3 is stopped, a large number of hangers 5 can be lifted together with the roller 6. I have.

Each hanger 5 has a hanger arm 8 extending horizontally in the direction of the plating tank 1, and a jig holding arm 10 is swingably supported by a bearing 9 provided at the tip of the hanger arm. The jig holding arm 10 has a shape in which the upper part of the bearing 9 is bent in the direction of the frame 2, and a roller 11 is provided at an upper end thereof. A jig 12 on which a work is set is held below the jig holding arm 10.

On the other hand, an upper portion of the frame 2 is provided with a backing plate 13 as shown. The abutment plate 13 is provided only at a position where the liquid needs to be drained among the stop positions of the traveling carrier. When the hanger 5 is lifted to near the upper limit by the lifting rail 7, the contact plate 13 comes into contact with the roller 11 of the jig holding arm 10. Therefore, when the hanger 5 further moves up from the position where the roller 11 hits the lower surface of the backing plate 13, the jig holding arm 10 is pushed by the backing plate 13 and rotated as shown in FIG. Draining is performed at an angle.

Reference numeral 14 denotes an electric conductor provided on the lower surface of the hanger arm 8. Jig holding arm as shown in FIG.
When the roller 11 is not in contact with the backing plate 13, the current
Is in contact with the electric conductor 15 on the jig 12 side, so that a current required for plating can flow through the jig 12.

In the jig tilting mechanism of the present invention having the above-described configuration, if the abutment plate 13 is provided at a position where the liquid needs to be drained among the stopping positions of the traveling carrier, the hanger stopped at that position. When 5 is lifted to near the upper limit,
The jig 12 can be automatically tilted by holding the upper end of the jig holding arm 10 with the backing plate 13. As described above, since the jig tilting mechanism of the present invention tilts the jig 12 by using the lifting power of the elevator-type plating apparatus, it is necessary to drain the liquid like the conventional one shown in FIG. It is not necessary to install a tilt cylinder at each of the various positions. In addition, it is not necessary to control the driving of these many cylinders as in the related art, and the equipment cost can be reduced.

[0010]

As described above, the jig tilting mechanism of the present invention holds the jig by holding the tip of the jig holding arm, which is swingably supported by the tip of the hanger, by using the contact plate. The jig is inclined with the arm. For this reason, the jig can be tilted using the lifting power of the elevator type plating equipment, and there is no need to install cylinders at each stop position as in the past, and special control is required for tilting the jig. There is no need to do. Moreover, there is an advantage that the jig can be easily inclined at any stop position only by installing the backing plate.
