Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a processing device that performs a series of surface treatments on light metal shapes, and is used to return empty electrolytic frames from which the treated shapes have been removed to the framing side. This invention relates to an empty electrolyte frame return device.

[Problems to be solved by conventional technology and invention]

In recent years, when manufacturing light metal shapes such as aluminum shapes and aluminum alloy shapes that have been subjected to oxidation treatment, coloring treatment, etc., various treatment tanks are successively installed to perform a series of treatments such as a cleaning layer, an electrolytic oxidation tank, an electrolytic coloring tank, etc. The molds suspended from the electrolytic frame are sequentially transferred to each of these processing tanks and processed. In this series of processes, first, at the start of the process (frame installation side), the form is laid down and attached to the electrolytic frame, and then the electrolytic frame is lifted and rotated 90 degrees.
The form material is suspended, and then in this state, the electrolytic frame is sequentially transferred to the processing tank by a crane and processed, and then rotated 90 degrees while lowering the electrolytic frame at the end of processing (frame removal side). and lay the mold material down.
This is done by removing the form from the frame. In such a series of processing steps, there are usually 4 to 5 cranes for transferring the electrolytic frames, and each crane sequentially transfers the electrolytic frames with hanging shapes to various processing tanks, It is programmed to operate in such a way that the empty electrolytic frames that have been removed from the processed shapes are sequentially relayed from the frame removal side and returned to the frame installation side.

However, if the cranes used to transfer electrolytic frames to each treatment tank are responsible for returning empty electrolytic frames, each crane will each account for approximately 20% of the total operating capacity.
This caused the problem that the processing efficiency of the mold material could not be improved because it was being operated to return empty electrolytic frames. In order to solve this problem, if a dedicated crane for returning empty electrolytic frames is installed, this crane must be installed outside of the crane for transferring the shapes to the processing tank, which increases the size of the equipment. There were problems in that the cranes were unstable to run and the equipment for running large cranes was expensive.

[Means for solving problems]

The present invention has been made in view of the above points, and provides an empty electrolytic frame return device in a light metal profile surface treatment device that can efficiently return empty electrolytic frames without increasing the size of the device like a dedicated crane. The purpose is to

That is, the present invention provides a processing apparatus that suspends a light metal profile from an electrolytic frame and sequentially transfers it to a plurality of treatment tanks to perform a series of surface treatments on the profile. A lifter is provided on the frame removal side to be removed from the electrolytic frame to raise or lower the empty electrolytic frame, and a lifter is installed on the frame mounting side in the upper space of the crane for sequentially transferring the electrolytic frame with hanging shapes to the processing tank. A surface of a light metal profile comprising: a rail provided extending from the side to the frame removal side; and an empty electrolytic frame conveying cart that has a clamp mechanism for gripping the empty electrolytic frame and travels while being suspended from the rail. The gist of this paper is an empty electrolyte frame return device in a processing device.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a surface treatment device for profile material equipped with an empty electrolyte frame return device 1 of the present invention, and in this treatment device,
First, the shape material 2 is attached to the electrolytic frame 3 in a lying state, and then the electrolytic frame 3 is rotated 90 degrees and raised to a suspended state, and stored in the frame installation side stockyard 4. Next, the electrolytic frames 3 stored in the stockyard 4 are transferred by the first crane 5 to the first treatment tank 6 (e.g. pre-treatment tank) for treatment, and then the second treatment tank 7 (e.g. The processed material is sequentially transferred to a third processing tank 8 (for example, a coloring tank), a fourth processing tank 9 (for example, an electrodeposition tank), and a fifth processing tank 10 (for example, a baking tank) for processing. Transfer to each processing tank is carried out successively from the first crane 5 to the second crane 11 and third crane 12. The processed mold material 2 is suspended in the electrolytic frame 3 and temporarily transferred to the stock yard 1 on the frame removal side.
It can be stored in 3. The shaped material 2 stored in the frame removal side stockyard 13 is removed from the electrolytic frame 3 after the electrolytic frame 3 is rotated by 90 degrees to make the shaped material 2 lie down. The empty electrolytic frame 3a from which the form material 2 has been removed is temporarily stored in a storage section (not shown), and then lifted by the frame removal side lifter 14 of the return device 1 of the present invention and transferred to the empty electrolytic frame transport cart 16 having the clamp 15.
The truck 16 is held by the cranes 5 and 1.
The empty electrolytic frame 3a is transported to the framing side by traveling on the rail 17 provided in the upper space of Nos. 1 and 12, and then the empty electrolytic frame 3a is lowered by the framing side lifter 18 and returned to a predetermined position. Ru. As shown in FIGS. 2 and 3, the trolley 16 in the device 1 of the present invention is equipped with a traveling motor 19, is suspended from a rail 17, and is configured to be able to travel along the rail 17. The profile 3 held on the trolley 16

As shown in FIG. 4, the cart 16 of the apparatus 1 of the present invention is held by the holding hand 21 of the lifter 14 at the position of the frame removal side lifter 14, and the empty electrolytic frame 3a
As shown in FIG. 2, the clamp 15 waits in an open state until it is lifted to a predetermined position. When the empty electrolytic frame 3a is lifted to a predetermined position by the lifter 14, the clamp opening/closing motor 20 is activated and the clamp 15 is rotated (the second
(in the direction of the arrow in the figure), the clamp 15 is closed and the empty electrolytic frame 3a is held on the cart 16 (FIG. 3). Next, the traveling motor 19 is operated to cause the cart 16 to travel along the rails 17, and the empty electrolytic frame 3a is transferred to the framing side. When the cart 3a reaches the position of the frame-installing side lifter 18, the clamp 15 opens and the empty electrolytic frame 3a is held by the holding hand of the frame-installing side lifter 18 and lowers. In this way, the empty electrolytic frame 3a is returned to the framing side, and the returned empty electrolytic frame is stored in a storage section (not shown).
