Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a coating line hanger suitable for a coating line of an automobile body.

(Prior Art) An example of a conventional hanger of this type is shown in FIGS. 6 to 9, and in FIGS. 6 and 7, 01 is a vertical bone, which is hung on a guide rail of an overhead conveyor (not shown). Suspended via 02. Reference numeral 03 designates an inverted U-shaped transverse bone, the central portion of which is suspended from the front and rear portions of the longitudinal bone 01 in a swingable manner. Reference numeral 04 denotes a chain hanging from both ends of the horizontal frame 03, and a car body 06 is mounted on a bar 05 spanning the lower ends of the pair of chains 04.

When the conveyor chain is towed, the car body 06 hung on this hanger is guided by the guide rails, and facilities such as hot water washing, degreasing, water washing, film formation, water washing, electrodeposition coating, water washing, and drying are performed in the painting line. To be painted in this order.

When painting spare parts of the vehicle body 06, such as fenders, doors, trunk lids, rear gates, engine hoods, as shown in FIG. 8 and FIG. Suspend multiple parts hanger 07 to
The auxiliary part 09 was hooked on the part hanger 07 via the hook 08, and the energizing cable 010 was fixed to the auxiliary part 09.

(Problems to be solved by the invention) In the above-mentioned conventional method, it is not only time-consuming and time-consuming to suspend the spare parts 09 on the hanger, but it is also necessary to suspend a large number of spare parts 09 in close proximity. Since a problem such as uneven coating may occur on the component 09, it is not possible to suspend a large number of auxiliary components 09, and thus there is a problem that the efficiency of coating is poor.

(Means for Solving Problems) The present invention has been proposed in order to address the above problems, and the gist of the present invention is to provide a suspension for engaging with a locking structure of a large object to be coated. In a hanger for a coating line that is equipped with a support mechanism and is used for electrodeposition coating by immersing the object to be coated in the electrodeposition liquid, from a cylindrical body whose upper end is blocked by a child hanger for hanging a small object to be coated. And a locking structure that is the same as the locking structure described above is provided, and the locking structure is engaged with the suspension support mechanism so that the frame is suspended from the hanger and is inserted from the lower end opening of the coupling metal. A coating line hanger characterized in that a plurality of hooks are provided whose tips abut against the inner surface of the top plate of the connecting fitting, and a plurality of child hangers are provided in the frame while the connecting fitting is engaged with these hooks. is there.

(Operation) Since the present invention has the above-described structure, a large object to be coated is suspended by the hanger by engaging the suspension structure with the retaining structure.

When painting a small object to be painted, the frame is suspended on the hanger by engaging the suspension structure of the hanger with the locking structure of the frame. Then, insert a plurality of hooks provided in the framework from the lower end opening of the connecting fitting provided in each child hanger, and bring the tip of the hook into contact with the inner surface of the top plate of the connecting fitting to provide the plurality of child hangers in the framework. Hang a small object to be coated on these child hangers.

(Embodiment) One embodiment of the present invention is shown in FIGS. 1 to 5.

In FIGS. 1 to 5, reference numeral 1 is a vertical bone made of a circular pipe suspended from a guide rail of a conveyor via a suspension rod 2. The vertical bone 1 is of a middle height and gradually descends toward both ends thereof. It is inclined to. Reference numeral 3 denotes a horizontal bone which is a circular tube fixed to both ends of the vertical bone 1 and is inclined so as to gradually descend toward both sides of the vertical bone 1. Reference numeral 4 denotes an L-shaped arm that is rotatably supported at both ends of the horizontal frame 3 via a shaft 5, and the lower end of the arm 4 has a vehicle body 7
The suspension support mechanism 6 that engages with the locking structure is provided. 8
Is a drain receiver fixed to the upper part of the arm 4, and guides the liquid dropped from both ends of the lateral frame 3 to the side of the vehicle body 7 to drop it. Reference numeral 9 denotes a frame, which has the same locking structure 10 as the locking structure of the vehicle body 7 on the bottom thereof, and a large number of child hangers 11 for suspending the auxiliary parts w are arranged at appropriate intervals. It is like this. The child hanger 11 has various shapes and structures depending on the type of the spare part w.
As shown in the figure, it comprises a connecting fitting 13 made of a cylindrical body whose upper end is closed by a copper plate 12, and a hook 14 fixed to the frame 9 is inserted from the lower end opening of this connecting fitting 13 and its tip end surface is the copper plate 12. It comes in contact with the lower surface of the.

Thus, since the tip surface of the hook 14 is in contact with the lower surface of the copper plate 12, the current resistance is small, and since the tip surface of the hook 14 is covered with the connecting fitting 13, it is possible to remove water during washing, hot water washing, etc. You can prevent hot water from hanging on the hook 14,
Further, even if the connecting fitting 13 is immersed in the electrodeposition liquid during electrodeposition coating, air stays at the top of the inside of the connecting fitting 13, so that the electrodeposition liquid does not adhere to the tip surface of the hook 14.

Then, when painting the spare parts w, the spare parts w are hung on a large number of child hangers 11 arranged at appropriate intervals in the frame 9, and the locking structure 10 of the frame 9 is suspended. The suspension support mechanism 6 of the arm 4 is engaged to suspend the arm 4 from the hanger.

(Effect of the Invention) In the present invention, a large number of small objects to be coated can be supported at appropriate intervals by suspending the small objects to be coated on a large number of child hangers provided in the frame. . Since this frame has the same locking structure as the locking structure of a large object to be coated, it is possible to easily and quickly attach the hanger suspension support mechanism to this locking structure in an easy and quick manner. Can be suspended.

Thus, it is possible to coat a large number of small objects to be coated all at once in the same procedure as a large object without causing color unevenness, etc., and greatly improve the coating efficiency of small objects to be coated. It becomes possible.

In addition, a connecting fitting made of a tubular body with the upper end closed is provided on the child hanger, and a plurality of hooks provided on the framework are inserted from the lower end opening of the connecting fitting so that the tip of the hook abuts the inner surface of the top plate of the connecting fitting. Therefore, even if the connecting metal fitting is immersed in the electrodeposition liquid, air remains at the top of the connecting metal fitting, and therefore the electrodeposition liquid does not adhere to the tip of the hook and the inner surface of the top plate of the connecting metal fitting.

Therefore, it is possible to prevent the situation where the connecting portion between the frame and the child hanger is painted, and the paint removing work when these are reused becomes unnecessary, so that the coating efficiency can be improved.
