Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a transport hanger for transporting objects such as objects to be coated in a suspended state, and more specifically relates to a swing prevention device for the transport hanger. It is.

(Prior art) Since it is necessary to paint the inner surface of an object such as an automobile body, the object to be painted must be continuously transported while suspended above an automatic coating machine (painting robot). A transport hanger is used.

The transport hanger includes a carrier that moves along a transport path that is set to pass through the coating machine;
The carrier is equipped with a transported object support member suspended via a rod, the transported object support member extending in a direction intersecting the transport path, and the object to be coated, such as an automobile body, is placed on this transported object support member.

By the way, the rod is swingably attached to the carrier, so that the position of the conveyed object support member can be changed as appropriate depending on the type of automobile body.

(Problems to be solved by the invention) In the conventional transport hanger described above, the transported object is supported in a swingable manner, so it tends to swing back and forth and from side to side as the transport hanger moves. Become.

Such oscillations become a major hindrance when painting objects such as automobile bodies with painting robots.

The present invention has been developed in consideration of the above-mentioned problems, and its purpose is to provide a swing prevention device for a transport hanger that prevents the objects being transported by the transport hanger from swinging. It is about providing.

(Means and actions for solving the problems) In order to achieve the above-mentioned object, the present invention has the following configuration. That is, a pair of left and right rods are swingably suspended from the front and rear ends of the carrier that moves along the conveyance path, and the lower ends of the pair of left and right rods at the front end are attached to the A front object support member extending in a direction intersecting the conveyance path is attached, and a rear object support member extending in a direction intersecting the conveyance path is attached to the lower end portions of the pair of left and right rods at the rear end portion. In the conveyance hanger, endless members running in synchronization with the movement of the carrier are disposed on both sides of the conveyance path so as to face the end surfaces of the front and rear conveyed object support members, respectively, and the endless members include: A concave portion is formed to receive and engage an end portion of the conveyed object supporting member, and a plurality of concave portions are formed over the entire endless member at slight intervals.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIGS. 1 to 3, 1 is an automobile body as an object to be conveyed, 2 is a conveyance hanger 2 for conveying the automobile body 1, and the conveyance hanger 2 has a carrier 3, and the carrier 3 is a conveyance rail. It is suspended at a predetermined height by a hanging member 5 that engages with 4. The hanging member 5 is engaged with the conveyance rail 4 via rollers 6, 6, . . . and is moved in the direction A by a drive device (not shown).

Rods 7, 7... are swingably suspended from the four corners of the carrier 3, and the lower ends of these rods 7, 7... have a cover extending in a direction making an angle of 90 degrees with respect to the A direction. The conveyance object support members 8 and 9 are attached, and the automobile body 1 is placed on the conveyance object support members 8 and 9 and conveyed.

Here, the conveyed object supporting members 8, 9 are the rods 7,
Since the support members 8 and 9 are swingably suspended from the carrier 3 via the support members 8 and 7, the longitudinal spacing between the support members 8 and 9 can be freely changed depending on the type of the automobile body 1.

Painting robots 11, 11 are arranged below the conveyance path 10 of the automobile body 1, and painting guns 11a,
The inner surface of the automobile body 1 is painted by 11a.

On both sides of the conveyance path 10, anti-swing members each consisting of endless belts 12 and 13 are arranged along the conveyance path. Each endless belt 1
2, 13 are supported by rollers 14, 14..., 15, 15, and rollers 15, 15 are supported by motor 1.
6 and 16.

The motors 16, 16 rotate in synchronization with a hanger conveying device (not shown), and the endless belts 12,
13 is supposed to run at the same speed as the hanger 2.

Concave engaging portions 17, 17, . The engaging portions 17, 17, . . . can be engaged with each other.

When the conveyance hanger 2 moves in the direction A and enters the inner surface painting process of the automobile body 1, both ends of the conveyed object support members 8 and 9 supporting the automobile body 1 are brought into contact with the concave portions of the endless belts 12 and 13. Joint part 1
7, 17, etc., respectively. Since the endless belts 12 and 13 run in the same direction (direction B in FIG. 1) at the same speed in synchronization with the movement of the transport hanger 2, the transported object supporting members 8 and 9
is prevented from swinging back and forth and left and right by the endless belts 12 and 13.
It will move in the A direction together with 13.

When the automobile body 1 thus transported passes above the painting robots 11, 11, the inner surface is painted by the painting guns 11a, 11a.

In the above embodiment, the anti-swing member was composed of an endless belt, but as shown in FIGS. 5 to 7, rubber 19, 1
Attach 9... at equal intervals, and rubber 19, 19...
Concave engaging portions 17, 17, . . . may be formed between them.

According to this embodiment, accurate synchronous rotation is possible by the sprocket (not shown) that meshes with the chain 18, and the conveyed object supporting members 8, 9 engage with the concave engaging portions 17, 17... The rubber 19 cushions the impact to a certain extent when this occurs.

(Effects of the invention) As described above, the present invention can adjust the interval between the conveyed object supporting members over a wide range and prevent the conveyed object supporting members from swinging back and forth and in the left and right directions. While making it possible to support various types of objects, it is possible to reliably prevent the object supported by the object support member from swinging.

In addition, simply by engaging the conveyed object support member with the recess, the interval after interval adjustment is locked in that state, and even when external effects such as painting are applied, the interval remains stable. In addition to being able to hold the transported object, it is also possible to restrict the shaking of the transported object, and compared to the case where structures for exerting these functions are provided separately, the number of structures can be reduced and the structure can be simplified.
