Abstract

PURPOSE:To make effective use of a space by oscillating opening and closing members with pivotted hunger arms by a cam rail for folding the arms when empty hungers are returned. CONSTITUTION:Rollers 9b-12b are fixed on outer arm parts 9a-12a of opening and closing members 9-12 fixed on a support member 5 to be guided by a cam rail 14 of a U-shaped section supported on a ceiling 1, and the opening and closing members are oscillated horizontally when the cam rail 14 is in a horizontal position A and vertically when it is in an upper position B. In the hunger arms 15-18 provided to correspond to the said opening and closing members 9-12, upper parts 15a-18a are fixed by pins 19 on the inner arm parts 9c-12c of the opening and closing members 9-12, and the lower parts 15b- 18b are provided with holding parts 20 and 21 of a car body 2. In this construction, when empty hungers are returned, hungers are folded to reduce their height by half to reduce the occupying space of the hungers for making effective use of the space of a factory.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a hanger for transporting a vehicle body while hanging it, for example, in the manufacturing process of a vehicle.

Generally, hangers like the ones mentioned above are suspended from ceiling rails installed in the transport direction of the vehicle body (goods) and are moved around. However, because the hanger needs to be straightened, the entire length of the hanger in the transport direction is There was a problem in that the ceiling height needed to be ensured, and the hangers occupied a large space, making layout difficult, especially in factories with low ceilings.

The present invention has been made in view of the above conventional problems, and basically includes a pair of opening/closing members pivotally attached to a support member suspended from a ceiling rail, and a pair of hanger arms attached to the opening/closing members. A pair of hanger arms that are pivoted together and closed at the bottom during transportation are guided by the support member's guide by the opening/closing member that swings on the cam rail during return, and while the upper part is pulled inward, the lower part swings upward. A new foldable hanger that can be folded open and halved the height of the hanger when returning an empty hanger, expanding the factory space and making it possible to develop an advantageous layout especially in factories with low ceiling heights. It is provided to

Embodiments of the invention will now be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a fixed frame 4 on which a ceiling rail 3.degree. 3 is installed is attached to the ceiling 1 of a factory along the direction in which the vehicle body 2 is transported.

Below the fixed frame 4 are frames 5a extending horizontally at right angles to the transport direction, and guide rollers 8 at both ends thereof. . . . , a support member 5 in the form of a rectangular frame long in the conveyance direction and rotatably attached thereto is provided, and 1 of the frame 5a of the support member 5 is provided. Support rollers 6.6 guided and supported by the ceiling rail 3.3 are attached to the front and back of the upper center in the direction of movement, so that the support member 5 is suspended and supported horizontally by the ceiling rail 3 so as to be movable in the transport direction. It has become.

Rods 7.7 extending in the feeding direction are supported at both ends of the frames 5a, 5a in the widthwise direction of the support portion 5, and guide rollers 8. . . , 8 are rotatably fitted into each other.

The fifth frame 5a of the support part A, rotating in the transport direction of the article 5a, is provided on both the front and rear sides, with a total of four

, 13 are pivotally connected to each other so as to be swingable.

The left and right opening/closing members 9.10 and 11.12 are staggered in front and rear positions so that their rocking movements do not interfere with each other.

Rollers 9b to 12b are attached to the outer arms 9a to 12a of each of the opening/closing members 9 to 12, and each of the rollers 9b to 12b is supported by a cam rail 14 having an opening-shaped cross section and supported from the ceiling 1 along the ceiling rail 3. 14 and guided by pin 13. ..., 1
The cam rail 14 swings around the cam rail 14.
．． When the cam rail 14 is in the lateral position A, it is swung horizontally, and when the cam rail 14.degree. 14 is in the upper position iB, it is swung vertically.

A total of four arm arms 15°, 16.17.
18 is a long middle part 15C-1 which is bent in a dogleg shape on the upper part 151-18a side and straight and long on the lower part 15b-IBb side.
8C, and the upper parts 15a to 18a are connected to each of the opening and closing members 9 to 18C.
12 inner arm portions 9C to 12C with pins 19. . . , 19, and the intermediate portions 15C to 18C extend downward while coming into contact with the respective guide rollers 8° . , 18
b are integrally connected by a mounting portion 20.21 of the vehicle body 2.

In addition, 22.22 is a stopper which restricts swinging of the opening/closing members 9-12 more than necessary.

If purchased as above, cam rail 14.
14 is in the horizontal position A and the opening/closing members 9 to 12 are swung horizontally, so that the upper parts 15a to 18a of the hanger arms 15 to 18 pivotally connected to the opening and closing members 9 to 12 are pushed outward. With the bent portions of the intermediate portions 15C to 18C in contact with the guide roller 8, the lower portions 15b to 18b extend in the 1-direction to be in a closed state, and the vehicle body 2 is placed on the placement portion 20.21.

Next, at the time of return, the cam rail 14.14 is set at the upper position B and the opening/closing members 9-12 are vertically swung, so the hanger arms 15-18 pivotally connected to the opening/closing members 9-12 are
While the intermediate portions 15C to 18C are guided by the guide roller 8, the upper portions 151 to 18a are drawn inward, and the lower portions 15b to 18b are swung upward to be in an open state.

Therefore, the hanger height of Ho in the closed position is halved to H2 in the open position.

As is clear from the above description, the present invention has a structure in which an opening/closing member to which a hanger arm is pivotally connected is swung by a cam rail, and the hanger arm is guided by a guide and swung upward while being pulled inward. Therefore, when an empty hanger is returned, it can be folded so that the height of the hanger is halved, and the space occupied by the hanger is reduced, making it possible to expand the space in the factory. In particular, it will be possible to develop the layout advantageously even in factories with low ceiling heights.
