Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a suspended conveyance device employed in, for example, an automobile paint factory.

Conventional technology For example, in an automobile paint factory, the body of the automobile is transported by a suspended conveyance device, immersed in a processing liquid (for example, paint liquid) in a processing tank, and after the body is pulled up, the liquid is drained. There is a transport line. Conventionally, in such hanging conveyance devices, the conveyed object support device (hanger) is
It is composed of a plurality of C-shaped arm rods connected to the trolley device, a support section attached to the free ends of these arm rods, and a plurality of connecting rods connecting the front and rear opposing arm rods. . Here, the connecting rods also serve as reinforcement, and a plurality of connecting rods are arranged on the same line in the vertical direction on the side surface portions of the arm rods.

Problems to be Solved by the Invention According to the conventional method described above, when the body is drained, the conveyed object support device is also drained, and at that time, droplets that fall from the upper connecting rod are collides with the lower connecting rod, and the rebound reaches and adheres to the body, which has an adverse effect on the body's ability to drain liquid. For example, in the case of paint liquid, the paint liquid splashes back and adheres to the body from which the liquid has been drained, resulting in uneven coating. To solve this problem, for example, as seen in Utility Model Publication No. 44044 of 1982, it has been considered to form the connecting rod into a mountain shape when viewed from the side and to allow the liquid to flow along the slope.
Even this is not sufficient, and the ball falls downward and bounces back.

Means for Solving the Problems In order to solve the above-mentioned problems, the hanging conveyance device of the present invention is provided by attaching a conveyed object supporting device to a moving body supported and guided by a rail, and attaching the conveyed object supporting device to the Consisting of a plurality of C-shaped arm rods connected to the front and rear of the moving body, a support section attached to the free ends of these arm rods, and a plurality of connecting rods that connect the front and rear opposing sides of the arm rods. However, the connecting rods are arranged with their positions shifted in the left-right direction.

Effects According to the configuration of the present invention, since the connecting rods are shifted in the left-right direction, droplets falling from the upper connecting rods fall downward without colliding with the lower connecting rods.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 1 designates a hanging conveyance device, which includes a trolley guide rail 2, a trolley drive device rail 3 installed above the trolley guide rail 2, and a trolley device 4 which is an example of a moving body guided by the trolley guide rail 2.
, a conveyed object support device 5 attached to the trolley device 4, and a trolley drive device (such as a chain conveyor) 6 guided by the trolley drive device rail 3. The trolley device 4 includes a front trolley 7, a pair of front and rear free trolleys 8 and 9,
Connecting rods 11 and 12 that connect the rear trolley 10, the front trolley 7 and the free trolley 8, and the free trolley 9 and the rear trolley 10;
It consists of a connection frame 15 that connects between trunnion pins 13 and 14 that are connected from both free trolleys 8 and 9. The conveyed object support device 5 includes C-necks 16 and 17 attached to the lower ends of the trunnion pins 13 and 14, support frames 18 and 19 attached to the lower ends of these C-necks 16 and 17, respectively, and these support frames. C-shaped arm rods 22A, 22 are attached to both ends of the arms 18, 19 via longitudinal pins 20A, 20B, 21A, 21B so as to be swingable from side to side.
B, 23A, 23B and these arm rods 22A, 22
Support parts 24A, 24B, 25A, 25 attached to the free ends of inwardly protruding parts 22a, 22b, 23a, 23b forming the lower part of B, 23A, 23B
B, and the arm rods 22A, 22B, 23A, 23B.
Multiple (3) connecting rods 26A, 26B, 27A, 27B, 28A, 28 connecting the front and rear sides of
It consists of B. Here, each connecting rod 26, 26
B, 27A, 27B, 28A, and 28B are arranged with their positions shifted in the left-right direction. Each of the trolleys 7, 8, 9, 10 has a guiding wheel 30.
and wheels 31 for preventing lateral vibration.
The front trolley 7 has a passive dog 33 that can be engaged with and detached from the drive protrusion 32 from the trolley drive device 6 so as to be movable up and down, and can be pivoted up and down via a horizontal shaft 34 in the middle thereof. The attached operating lever 35 extends forward. The rear end of the operating lever 35 and the lower end of the passive dog 33 are connected via a pin. Therefore, the operating lever 35 and the passive dog 33 are
When the dog moves upward, the passive dog 33 is moved downward. Normally, the passive dog 33 is
The movement lever 35 is raised by weight biasing on the distal end side, and the upper limit of the movement lever 35 is regulated by the base end side of the movement lever 35 coming into contact with a stopper. The other rear trolley 10 is connected to the operating lever 3.
A cam tail 36 for moving the shaft 5 upward extends rearward. Reference numeral 37 indicates the body of an automobile, which is an example of the object to be transported.

In the embodiment described above, the trolley device 4 is normally moved by the driving protrusion 32 engaging the passive dog 33. Then, a combination of making the support device 5 swing the arm levers 22A, 22B, 23A, and 23B as shown in the imaginary line (solid line) in FIG. This alignment allows the body 37 to be loaded and unloaded. The body 37 is immersed together with the support device 5 in a processing tank, and after being pulled up, the processing liquid is drained. At that time, each connecting rod 2
6A, 26B, 27A, 27B, 28A, 28B
are misaligned in the left-right direction, so droplets A and B from the upper connecting rods 26A, 26B, 27A, and 27B are located on the lower connecting rods 27A, 27B, and 28.
It will fall without colliding with A and 28B.

In addition, while bringing the lowest connecting rods 28A, 28B closer to the body 37 side, the connecting rods 27A, 27
When a rigid body type is used that does not require B, it is possible to prevent splashing of droplets from the body 37, and it also contributes to improved work efficiency such as opening and closing of doors.

Note that the support device 5 may be of a one-arm type as shown in FIG.

Effects of the invention According to the invention having the above configuration, since the connecting rods are shifted in the left-right direction, droplets falling from the upper connecting rods fall downward without colliding with the lower connecting rods. This allows for no splashing at all, and suitable liquid drainage can be achieved at all times.
