Description

[Detailed description of the invention] Technical field This invention relates to a support mechanism for objects to be painted in a painting line, and in particular allows the foldable support stand to be easily folded even if paint adheres to the hinge part, and improves accuracy. The present invention relates to a support mechanism that achieves this.

Prior Art A conventional example will be explained with reference to FIGS. 7 and 8. In a painting line, for example, an automobile body painting line, various dimensions of passenger car bodies, truck front bodies and cabs, truck loading beds, etc. Objects to be coated with different shapes (see Figure 1)
is transported for painting. These objects to be painted are usually placed on support stands 2 of various support mechanisms 1 installed on a trolley that runs on the floor, but if the specifications of the objects to be painted change. Since there is also the support stand 2 which is no longer needed, the support stand is usually configured to be foldable. The hinge H of the conventional support stand 2 is composed of only a pin 3, and a positioning stopper 5 having a U-shaped cross section is fixed to the base 4 by welding, and the pin 3 is inserted into the hole 5a. It is fixed. The support base 2 has two parallel plates 2b fixed to its base end 2a by welding, and one surface 2c of the support base 2 is attached to the inner surface 5 of the positioning stopper 5.
The plate 2b is positioned in the upright state by abutting against the pin 3, and the plate 2b is fixedly and pivotally connected to the pin 3. When the support stand 2 is not needed, the support stand can be folded up by rotating it around the pin 3 as shown by arrow A in FIG.

However, according to the conventional support mechanism 1, since the hinge H depends on the pin 3, the two plates 2b of the support base 2 are brought into close contact with the inner surface 5d of the side plate 5b of the positioning stopper 5, and the axis of the pin 3 is Since the support base 2 is restrained in the direction, if paint adheres to this close area, the support base 2 will not fold smoothly, and the inner surface 5c of the positioning stopper 5 and one side 2c of the support base 2 may
If paint adheres to the support base 2, positioning accuracy will deteriorate when the support base 2 is used in an upright position. For this reason, this conventional example has the disadvantage that cleaning work is required to remove the paint adhering to these important parts by dabbing or other methods about once a month.

Purpose The present invention was made in order to eliminate the drawbacks of the above-mentioned prior art, and its purpose is to provide a device that can be folded as necessary to place objects to be painted with different specifications on a painting line. In the support mechanism configured as shown in FIG. The paint can be peeled off with great force each time, and the axial movement of the hinge of the support base is restrained by the threaded engagement of the bolt and nut, thereby eliminating close contact areas where it would be a problem for paint to adhere. By doing so, it is possible to eliminate the need for cleaning for a long period of time.

Configuration In short, the present invention is a plurality of support mechanisms configured to place objects to be coated with different specifications in a painting line, and the support mechanisms include a base and a rotary structure connected to the base via a hinge. It consists of a support stand which is movably connected and held vertically when in use, and is foldable as required, and on which the object to be coated is placed, and the base and the support stand are rotated. The movably connected hinge is characterized in that one end is a bolt and the other end is a nut screwed into the bolt.

The present invention will be explained below based on embodiments shown in the drawings. In the painting line 6 as shown in FIG.
The paint is placed on a support mechanism 12 attached to a trolley 11 that is made to travel at a speed of 100 degrees. In this case, the support mechanism 1 according to the present invention
2 may be unnecessary and a nuisance depending on the type of object 8 to be coated, so it is configured to be foldable. This is because the height of the support base 14 in the upright state is particularly high compared to the other support mechanisms 13.

A base 15 of the support mechanism 12 is welded to the truck 11, and the support 14 is foldably pivoted to the base 15 by a hinge H, and various attachments 16 are fixed to the upper part. In the present invention, the hinge H has one side attached to the bolt 18.
The other end consists of a nut 19 that is screwed into the bolt. A nut 1 is attached to the upper surface 15a of the base 15.
9 are welded to both sides of the hinge member 20 in a horizontal state. Further, a plate-shaped positioning stopper 21 is welded to one surface 15b of the base 15, and a thick portion thereof serves as a positioning portion 21a. The bolt 18 is welded to the support base 14, passes through two U-shaped parallel plates 22 in the horizontal direction, and is screwed into the nut 19, and both ends 18a of the bolt 18 are welded to the parallel plates 22. When assembling, the bolt 18 alone is inserted from one side 22a of the parallel plate 22, screwed into the nut 19 to pass through the hinge member 20, protruded from the other side 22b, and fixed to the parallel plate 22 by welding. . As a result, the support stand 14 is restrained in the lateral direction with respect to the base stand 15 and pivotably attached to the base stand 15, thereby forming a hinge H.

Function The present invention is constructed as described above, and its function will be explained below. During use of the support mechanism 12 according to the present invention, the support stand 14 stands up and one surface 22c of the two parallel plates 22 comes into contact with the positioning part 21a of the positioning stopper 21, and the support stand 14 is in the normal upright position. is positioned. In this case, if the positioning part 21 of the positioning stopper 21
If paint adheres to the surface 22a of the parallel plate 22, the pressure-receiving area between them is very small, so the surface pressure acting on the positioning stopper 21 from the support base 14 is very high, and the paint adheres here. The paint that has been applied peels off and is removed every time the support base 14 is placed in an upright position.

Next, when the support stand 14 in the upright state is folded in the direction of arrow A as shown in FIG.
The bolt 18 fixed to the bolt 18 rotates relative to the nut 19, and at this time, the paint adhering to the exposed portion of the bolt 19 is easily peeled off from the bolt due to the strong force caused by the screw engagement with the nut 18. The threaded portion of the bolt 18 quickly becomes clean.
Also, the bolt 1 that is not involved in threading every time there is ups and downs.
Since the paint attached to the part 8 does not cause any trouble, it may remain attached. In short, the hinge H of the present invention consists of a bolt 18 and a nut 19.
Therefore, each time the support base 14 is folded, the bolt 18 moves in the axial direction relative to the nut 19 by approximately 1/3 of the lead of the threaded portion (when rotated approximately 120 degrees). Since the axial movement is performed by the screw engagement between the male thread of the bolt 18 and the female thread of the nut 19, paint adhering to the threads of the bolt 18 easily peels off.

As described above, according to the present invention, the support stand 14 of the support mechanism 12 does not have any problem even if paint adheres to the hinge H, and the function of the positioning stopper 21 does not have to be affected by the adhered paint, so it can be used for a long period of time. There is no need to clean it over time, it can always be folded smoothly, and positioning accuracy is maintained in good condition.

Effects Since the present invention is constructed and operates as described above, in a coating line, a support mechanism that is configured to be foldable as necessary for placing objects to be coated with different specifications can be used. Since the hinge of the stand is composed of a bolt and a nut screwed onto the bolt, even if paint adheres to the hinge, the paint adhering to the bolt surface can be peeled off with great force each time by the folding action of the support stand. In addition, since the axial movement of the hinge of the support base is restrained by the threaded engagement of the bolt and nut, it is possible to eliminate close-contact areas that would be problematic if paint adhered to them, making it possible to clean them over a long period of time. The effect is that you don't have to do it.
