Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a hanger suitable for an overhead conveyor or the like provided in a painting line of an automobile body.

(Prior Art) An example of a conventional hanger of this type is shown in FIGS. 4 and 5, and 01 is a vertical frame, which is hung from a guide rail of an unillustrated overhead conveyor via a hanging rod 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 so as to be swingable. Reference numeral 04 denotes a chain hanging from both ends of the horizontal frame 03, and an object to be coated, that is, 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 run, the car body 06 hung on this hanger is guided by the guide rails and washed in the painting line with hot water, degreasing, rinsing, film formation, rinsing, electrodeposition coating, rinsing, drying, etc. It is painted by passing through the facilities in this order.

(Problems to be solved by the invention) In the above-mentioned conventional hanger, when the hanger passes through the coating line, liquids such as hot water, water, and chemical liquids used for the treatment are applied to the vertical bones 01 and horizontal bones 02 of the hanger. If these liquids drip onto the vehicle body 06 before entering the electrodeposition coating device or before entering the drying furnace, the coating on the part where the liquid is dropped becomes defective. Since the portion where was dripped was subjected to treatments such as partial polishing, primer repair, and repainting, there was a problem that a great deal of labor and cost were required.

(Means for Solving the Problem) The present invention has been proposed to address the above-mentioned problems, and the gist of the present invention is that it is a middle height suspended from a guide rail of a conveyor toward both ends. The transverse bones that gradually descend toward both sides of the longitudinal bones that are gradually descending are fixed to both ends of the longitudinal bones, and the liquid guiding rod for guiding the liquid flowing down the lower surface of the longitudinal bones to the lower surface of the lateral bones is described above. A hanger characterized in that the hanger is constructed by smoothly bending from the lower surface of the end portion of the vertical bone to the lower surface of the end portion of the horizontal bone.

(Operation) Since the present invention has the above-described configuration, the liquid attached to the vertical bone and the horizontal bone flows down the lower surface thereof toward the end thereof. Then, the liquid flowing along the lower surface of the vertical bone and reaching the both ends thereof is guided to the lower surface of the horizontal bone through the liquid guiding rod, and then drops along the lower surface of the horizontal bone from both ends thereof.

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

In FIGS. 1 to 3, reference numeral 1 is a vertical frame composed of a circular tube suspended from a guide rail of a conveyor via a suspension rod 2, and is inclined so as to gradually descend toward both ends at a middle height. ing. 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 pivotally supported at both ends of the horizontal frame 3 so as to be rotatable about an axis 5. An attachment 6 attached to a lower end of the arm 4 serves as an object to be coated, that is, a vehicle body 7 of an automobile. Is supported. Reference numeral 8 denotes a drain receiver fixed to the upper part of the arm 4, which guides liquid dropped from both ends of the horizontal frame 3 to the side of the vehicle body 7 to drop it. Reference numeral 9 denotes a liquid guide rod for guiding the liquid flowing down along the lower surface of the longitudinal bone 1 to the lower surface of the lateral bone 3, and as clearly shown in FIG. It is installed with a smooth curve over the lower surface. The upper end of the liquid guiding rod 9 is tapered so that the liquid that has traveled down the lower surface of the vertical bone 1 and has flowed down to the end of the vertical rod 1 can smoothly ride on the liquid guiding rod 9.

In the process of the hanger passing through the coating line, the liquid adhered to the surfaces of the vertical bones 1 and the horizontal bones 3 is made up of the circular pipes of the vertical bones 1 and the horizontal bones 3. Reach Since the vertical bones 1 and the horizontal bones 3 are inclined (preferably 10 ° or more) so as to gradually descend toward their ends, the liquid flows down the lower surface thereof toward both ends thereof. The liquid that has reached the lower surface of the end portion of the vertical bone 1 rides on the liquid guiding rod 9 and is guided to the lower surface of the end portion of the horizontal bone 3 along the liquid guiding rod 9. 1 of the liquid that has reached the lower surface of both ends of the transverse bone 3
The parts are transmitted to the arm 4, but most of them drop on the drain receiver 8 and are guided by the drain receiver 8 and fall to the lateral outside of the vehicle body 7.

(Effect of the Invention) In the present invention, since the horizontal bones that gradually descend toward both sides are fixed to both ends of the vertical bones that are suspended from the guide rails of the conveyor and gradually descend toward both ends at the middle height, the vertical bones are fixed. And the liquid adhering to the transverse bone flows down the lower surface toward the end. Then, the liquid that has passed through the lower surface of the longitudinal bone and reached the lower surfaces of both ends thereof travels through the liquid guiding rod that is installed so as to smoothly bend from the lower surface of the end portion of the vertical bone to the lower surface of the end portion of the horizontal bone. Is guided to the lower surface of the end portion of the cross-section of the horizontal bone, and then drip from both ends along the lower surface of the horizontal bone. Therefore, the liquid adhering to the vertical and horizontal bones of the hanger does not drip on the object to be coated suspended on the hanger, and therefore the labor and cost for repairing the defective coating are reduced unlike the conventional ones. It becomes possible to save money.
