Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device for materials to be treated in surface treatment equipment such as plating.

Surface treatment, such as plating, consists of various processing steps such as washing, neutralizing, and plating the material to be treated.The material to be treated is suspended from a carrier bar and is sequentially lowered and immersed in a number of consecutively arranged treatment tanks. , pull up,
transported. Such work is carried out using a transport device that runs on a ceiling rail installed above the processing tank. A carrier bar that suspends the material to be processed is transported from the initial process to the final process, and in order to improve productivity, it is common practice to run several transport devices in one series.

However, since several conveyance devices usually run on the same ceiling rail, a method is adopted in which the entire process is divided into several steps and one conveyance device is applied to each division. In other words, the carrier bar suspending the material to be processed is sequentially transferred to the next conveying device and moved until the entire process is completed. In this way, the production amount can be increased by the number of conveying devices.

To explain this delivery according to FIG. 1, the material to be processed 8 suspended on the carrier bar 9 is
0a, it is transported to the post-processing tank 1c where it is sequentially processed in the processing tanks 1a and 1b. The slider 5 of the conveying device 10a descends and moves the carrier bar 9 on the carrier 11 to the saddle 1 provided on the side edge 12 of the processing tank 1c.
Board the 3. The carrier 10a is the carrier 1
1 is moved slightly lower than the saddle 13 in the direction of the arrow 14, and then the empty carrier 11 is lifted onto the processing tank 1c by the slider 5 and returned to the processing tank 1a.

When the transport device 10a starts to return, the processing tank 1d
The upper transport device 10b is the saddle 13 of the processing tank 1c.
Move onto the processing tank 1c to receive the upper carrier bar 9. After the carrier 11 is lowered below the saddle 13 by the slider 5, the carrier 11
The conveying device 10b moves until the mounting portion 15 of the carrier bar 9 is under the carrier bar 9, and then the slider 5 is raised to receive the carrier bar 9 and convey it to the next processing tank 1d. In this way, the carrier bar 9 that suspends the material to be processed 8 is sequentially transferred between the respective conveying devices.

However, such a transfer requires the step of temporarily placing the carrier bar 9 on the saddle 13 in order to avoid interference between the transport devices 10a and 10b, and if there are many transport devices, this will increase wasted time and reduce production. We cannot expect much improvement in sexual performance. In addition,
In order to temporarily place the carrier bar 9 on the saddle 13, the material to be treated 8 must be immersed in an unnecessary processing tank, and space and equipment for temporary storage are required in place of this processing tank, making it impossible to downsize the equipment. There is a drawback.

In view of the above-mentioned problems, an object of the present invention is to provide a processing material conveyance device for a surface treatment facility that eliminates wasted time in transferring carrier bars and does not require temporary storage equipment for transfer.

The gist of the present invention is that a plurality of carrier vehicles 3 run on ceiling rails in the front and back direction constructed above the processing tanks 1 that are arranged continuously in the front and rear, and that the left and right legs hang down from each carrier 3. Gate-shaped guide arm 4
The left and right sliders 5 move up and down integrally, a pair of slide guides 6 arranged in a substantially V-shape when viewed from one running direction of the transport vehicle on the same horizontal plane on both inner sides of the sliders 5, and the slide guides. 6, the left and right ends of a carrier bar 9 that suspends the material 8 to be processed are mounted on the slide rails 7 of the first transport vehicle and transported to the second transport vehicle. This is a processing material conveyance device for a surface treatment facility, characterized in that the material is transferred down onto a slide rail of the surface processing facility.

Embodiments of the present invention will be described below based on the drawings.
FIG. 2 is a side view showing the structure of the present invention, FIG. 3 is a front view thereof, and FIG. 4 is a plan view taken in the direction of the - arrow in FIG.

The surface treatment equipment in Figure 2 is a treatment tank 1 and a conveyance device 1.
Consists of 0. In FIGS. 2 to 4, the transport device 10 includes a transport vehicle 3 that runs on a ceiling rail 2 installed above the processing tank 1, a slider 5 that moves up and down a gate-shaped guide arm 4 that hangs down from the transport vehicle 3,
The slider 5 includes a pair of slide guides 6 arranged on the same horizontal plane in a V-shape on both inner sides of the slider 5, and a slide rail 7 that moves on the slide guides 6 by a drive source (not shown). Note that 16 is a protruding rail provided at the center of the slider 5.

A carrier bar 9 suspends the material 8 to be processed by hooks 17, and is mounted on the slide rail 7 and transported to each processing tank. Note that a guide 18 guides the forward and backward movement of the carrier bar 9 by the slide rail 7, and is engaged with the aforementioned protruding rail 16 to prevent changes in the riding state due to movement of the carrier bar.

Next, the transfer of the carrier bar 9 between the conveying devices 10a and 10b will be explained based on the configuration of the present invention. FIG. 5 shows the positional relationship between the slide rail 7 and the carrier bar 9 when the two conveying devices 10a and 10b approach each other to transfer the carrier bar 9. As shown in FIG. In order to make it easier to understand the amount of movement of the slide rail 7, the center of the slider 5 of each conveying device is indicated by a chain line 19. In the following description, suffixes a and b are added to related symbols, and conveyance devices 10a,
10b.

Now, as shown in FIG. 5, a case will be described in which the carrier bar 9 is mounted on the front end of the slide rail 7a and the carrier bar 9 is conveyed in the direction of the arrow 20.
The transport device 10a approaches the transport device 10b from the rear (left side in the figure) and is arranged so that the front end of the slide rail 7a is above the slide rail 7b. At this time, the slide rail 7a is at the center 19
The slide rail 7b is located forward (shifted) from the center 19b.

Next, when the slider 5b is raised, the carrier bar 9 on the slide rail 7a

The carrier bar 9 supported on the side edge of the first
When unloading using the slide rail 7a of the transport device 10a, the slide rail 7a of the transport device 10a is made to protrude forward (to the right in FIG. 5), and the front end of the slide rail 7a (right end in FIG. 5) The carrier bar 5 is scooped up, the carrier bar 9 is raised by the slider 5, and the conveyance vehicle 3 is then moved forward. Second transport device 10b waiting in front
The slide rail 7b is made to protrude rearward (to the left in FIG. 5), and the slide rail 7a is advanced at a position slightly higher than this slide rail 7b, so that the front end of the slide rail 7a touches the rear end of the slide rail 7b. Overlap until the sandwiching position. Thereafter, the slide rail 7a is lowered and the carrier bar 9 at the front end of the slide rail 7a is transferred onto the rear end of the slide rail 7b. Thereafter, the slide rail 7b is slid forward within the slide guide within the transport device 10b, and the received carrier bar 9 is transferred to the transport device 10b.
on the center 19b, carry it to a predetermined position for the next process, and lower it into the target processing tank. By repeating such operations, it becomes possible to smoothly transfer the carrier bar 9 from the conveying device in the previous process to the conveying device in the subsequent process above the processing tank.

Note that when the conveyance device 10b receives the carrier bar 9 from the conveyance device 10a, the slide rail 7b
