Abstract

PROBLEM TO BE SOLVED: To execute the surface treatments of aluminum sash shapes by commonly using treating stages and by line layouts capable of dealing with combinations of many kinds of shapes regardless of the specifications (kinds) of the shapes, such as loading, pretreating stage and unloading, in order to reduce labor force and initial cost in the lines for executing the surface treatments of the aluminum sash shapes. SOLUTION: The lines for executing the surface treatment are arranged in juxtaposition. The line constitution capable of freely combining the specifications treatable by the respective treating stages by blocking the lines by each treating stage, for example, anodizing stage 22, coloring stage 23 and coating stage 24, among the surface treating sections 20 is adopted. Further, the lines are so arranged that the treatments may be executed by commonly using the same devices and treating stages regardless of the treating specifications of the shapes, such as loading sections 10, pretreating stages 21 and unloading sections 30.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertically suspended surface treatment method for a long aluminum sash profile made of aluminum or aluminum alloy, and more particularly to a method for laying out a treatment line in the surface treatment step.

[0002]

2. Description of the Related Art A vertically suspended surface treatment line for a long aluminum sash section is roughly divided into a load section, a surface treatment section and an unload section. For example, a schematic side view of a serial type surface treatment line shown in FIG. First, the load section 10 of the step of mounting and stocking the aluminum long shaped material 1 supplied from the pallet on the carrier bar 2, and then mainly includes four steps of a pretreatment step, an alumite step, a coloring step and a coating step. In the surface treatment section 20, the aluminum profile 1 suspended from the carrier bar 2 is sequentially dipped and treated in the respective predetermined tanks 4 according to the predetermined specifications by the carrier 3, and is attached to the carrier bar in the reverse of the loading section. It is composed of an unloading section 30 which removes the surface-treated aluminum profile from the carrier bar and loads it on a pallet.

[0003]

[Problems to be Solved by the Invention] With the increasing demand for multi-product and composite products for aluminum sash profiles, conventional surface treatment lines (serial type lines) have already been installed for multi-product and composite products. Even if you try to add more processing steps to the line,
There is no choice but to use a large modification of the existing line, for example, a method of deleting a certain processing step and making a new processing step, or a new method of constructing a new surface processing line.

However, the following problems occur when trying to deal with such a method. That is, in the former case, it is necessary to temporarily stop the production of the existing line, and the production of other products is stopped. On the other hand, if the line is expanded to two series-type lines as in the latter case, a huge cost is required for the construction of the new line, and a worker is required for the new line.

Incidentally, depending on the scale of the new specification, when a new specification can be made, a line has been newly added like the latter.

Therefore, an object of the present invention is to provide a specification (product type) of a profile such as load, pretreatment process and unloading in order to reduce labor and initial cost in a line for surface treatment of aluminum sash profile. Despite this, it is an object of the present invention to provide a surface treatment method for aluminum or aluminum alloy material, which can be shared by the apparatus and treatment steps and can be used in a line layout capable of coping with various types of shape materials and compounding.

[0007]

As a result of research to achieve the above object, the inventors of the present invention have found that in a surface treatment line for an aluminum profile, the lines are arranged in parallel and the lines are divided into blocks according to each treatment step. The line configuration allows you to freely combine the specifications (product types) that can be processed for each processing step, and the same equipment, regardless of the processing specifications (product types) of the profile, such as loading, pretreatment process, and unloading. In the process that requires treatment, it has been found that the above problem can be solved by arranging a device and a line so that the treatment process can be shared in order to reduce labor and initial costs, and the present invention has been reached. .

That is, according to the present invention, in a surface treatment method for treating the surface of a material to be treated made of aluminum or aluminum alloy, the lines for the surface treatment are arranged in parallel, and the lines are divided into blocks according to each treatment step. It has a line configuration that allows you to freely combine the specifications that can be processed according to the processing process, and further unloads the loading process that attaches the material to be processed to the carrier bar, the pretreatment process and the surface processed material from the carrier bar. It is intended to provide a surface treatment method for an aluminum or aluminum alloy material, characterized in that three steps are shared.

[0009]

The method of the present invention is shown in the layout of the surface treatment line as shown in FIG. 1. The layout of the treatment tanks is a common process (loading, loading,
Pre-treatment process, unloading) and are in parallel.
In the product transfer line of one line that linearly reaches the unload from the pretreatment process, and also from the pretreatment process, go through the alumite process of one line and proceed to the coloring process of the other line, then the one of the line. As another product movement line that goes through the painting process is illustrated, by dividing the line for each treatment process, it is possible to freely combine specifications (product types) that can be treated for each treatment process. In the present invention, the following operational effects can be obtained.

(1) Reducing the number of workers If the lines are arranged in two lines in series according to the conventional method for new processing specifications, the total number of workers for 10 persons per line is 2
It requires 0 people, but by sharing the loading, pretreatment and unloading, the line can be operated by 10 people, which is the same as one line in series.

(2) Even when the processing solution in the processing tank is replaced or the processing equipment is modified for a new processing specification, it is possible to operate either one of the parallel lines, so that the production of the conventional specification stops the line. You can continue without.

(3) A combination of the alumite process, the coloring process, and the painting process is possible, which is more than several times the number of product processing specifications that can be processed by one line in the past. It is easily understood from the line layout shown in Table 1, a comparison table of the number of processing specifications for each processing step, and the number of processing specifications of the final product. In addition, the comparison in Table 1 is based on the specification that can process one series line.

[0013]

[Table 1] Regarding the respective layouts compared with Table 1, (1) the serial type 1 line is a general layout from the past, as shown in FIG. 2, and (2) the serial type 2 line is As shown in Fig. 3, the layout is a series of 1 line in 2 series. (3) The parallel line for load / unload sharing is a serial type except for sharing load and unload as shown in Fig. 4. The configuration is similar to the two lines.

(4) The multi-process parallel line has the layout according to the present invention as shown in FIG. 1, and as described above except that the loading, pre-processing and unloading are shared. The line is divided into blocks for each process, and the combination of the alumite process, coloring method and painting process is free. In addition, the movement between the lines is performed by transferring the frame material suspended from the carrier bar to each block by a carrier, a traverser, a carriage, or the like.

[0015]

EXAMPLE FIG. 1 is a schematic plan view showing the layout of a multi-process shared parallel type line used in this example.

The surface treatment lines are arranged in parallel, the loading section 10, the pretreatment step 21 and the unloading section 30 are shared, and the alumite step 2 of the surface treatment section 20 is used.
2. The line is divided into blocks for each of the coloring step 23 and the painting step 24, so that the specifications that can be processed can be freely combined, which is extremely advantageous for compounding the specifications.
In addition, since there are many processing tanks even when dealing with multiple types of products, the processing specifications of the final product reach several times or more that of the serial one line.
Further, since the load section and the like are shared as described above, the facility cost is low correspondingly, and the labor cost for the line is almost the same as that of the serial type one line, and the operation is possible.

[0017]

[Comparative Example] A series type line which is a conventional general layout as a surface treatment line and a line layout similar to the improved type will be described with reference to the drawings.

The series type 1 line shown in FIG. 2 can meet a new specification by replacing the processing liquid in the processing tank.
Instead, specifications that could be processed conventionally cannot be processed. In addition, since there are few processing tanks, there is a limit to the combination of alumite specifications, coloring specifications, and coating specifications. On the other hand, both equipment and labor costs are minimal, but the equipment must be modified every time the specifications change.

The in-line type 2 line shown in FIG. 3 is basically the same as the in-line type 1 line for dealing with a variety of products and compositing, but it is advantageous because of the large number of treatment tanks. However, it is fatal that the equipment cost is twice as much as the serial type one line and the labor cost is also twice as much.

The load / unload parallel line shown in FIG. 4 has a low equipment cost because the load / unload of two series lines is shared, and the labor cost is almost the same as that of the one line line. Although advantageous, there are limits, and the processing specifications of the final product are about the same as the serial two lines.

[0021]

As described above, in the surface treatment method of the present invention, the surface treatment line layout is arranged in parallel, and the line is divided into blocks for each treatment step. It can be freely combined, and the number of processing specifications of products that can be processed with the conventional serial one line can be increased more than several times, and it is possible to sufficiently cope with the wide variety of aluminum profiles and compounding. It may be a surface treatment method.

Further, according to this method, since the load, pretreatment process and unload are of the common type, the facility cost is reduced by that amount, and the operation can be performed by the personnel who are not much different from the serial one line. .
