Abstract

PURPOSE:To enable continuous coloring of small amts. of many kinds of products by putting the products on based sheets and coloring them by AC electrolysis. CONSTITUTION:Products 15 to be colored are put on base sheets 16, transferred on a transfer system 14 and colored by AC electrolysis in a coloring equipment 12. The sheets 16 are made of Ti and have deeper recesses than the thickness of the products 15. Small amts. of many kinds of products can be continuously colored.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for continuously coloring small lots, irregularly shaped objects, foils, etc. by alternating current electrolysis.

<Prior Art> The present applicant has already disclosed a method for continuously coloring a stainless steel plate or a copper strip by alternating current electrolysis. These are very suitable for mass production of small varieties.

A simple explanation of its configuration as shown in the fourth drawing is as follows: stainless steel 1
The lilFt is passed from the coil 2 through the pinch rolls 3, welded at the wells 4 as necessary, and sent from the feeder 5 to the coloring equipment 6 that performs alternating current electrolysis, where it is colored in an appropriate color, and then transferred to the feeder 7. , shears 8, and pinch rolls 9, and is wound up as a coil 10.

<Problems to be solved by the invention> However, high-mix low-volume production or thin plates (for example, 0.1
Various problems have arisen with regard to foil bodies such as those with a thickness of 5 mm. For example, if the material to be colored is a thin plate such as foil, it is difficult to transport it, so coiling has been the solution. In the case of this coiling, threading,
In addition to an increase in the proportion of the total setup time for welding, cutting, coiling, and recoiling operations, the yield rate was reduced due to the occurrence of defective parts at the leading and trailing ends.

Furthermore, it is difficult to transport small items having circular, square, or other irregular shapes in small lots. There was a problem in that there was too much wasted material when these were punched out from colored stainless steel plates produced by conventional methods.

Therefore, an object of the present invention is to provide a continuous coloring method that can be easily adapted to the production of various items such as irregularly shaped items, small items, foil bodies, and small lot production without reducing the yield. be.

Means for Solving the Problems> The present invention provides a continuous coloring method characterized in that when coloring a material to be colored by alternating current electrolysis, the material to be colored is placed on a base plate and colored. It is something.

The present invention will be explained in more detail below.

Colorants are also required for stainless steel sheets or copper strips that are difficult or wasteful to color while being passed through them continuously using a conveyance system, as in the past.

For example, there are shapes that are not constant compared to steel plates, such as circles, squares, heart shapes, and character shapes. These are generally small items that are not held between rollers in the conveyance system, for example. Furthermore, even if it can be held in place, it may end up in a cantilevered state where only one side is supported, which is a problem in terms of coloring.

Further, in the case of a thin foil-like plate, there are many problems in transportation.

Particularly when it comes to small items, they may float when sent through the electrolyte, and may even become impossible to color.

The present invention provides a method for continuously and appropriately coloring such irregularly shaped objects, such as foils, which have transportation problems or are disadvantageous in small lot production.

The continuous coloring method of the present invention will be explained with reference to FIG.

In the method of the present invention, an inlet facility 11, a coloring facility 12 for performing alternating current electrolysis, and an outlet facility 13 are sequentially provided.
A transport system 14 is provided in these facilities. The conveying system 14 may be any conventionally used rollers, belt conveyor, or the like.

The feature of the present invention is that the material to be colored 15 such as the above-mentioned irregular shaped body or foil is placed on the base plate 16 and the base plate 16 is conveyed on the conveyance system 14 while coloring is carried out. As a result, the above-mentioned problems arising from the coloring material are solved at once.

FIG. 2 shows a state in which the material to be colored 15 is placed on the base plate 16 and is being conveyed. A large number of small square and triangular objects are placed on the mother board 16.

Since it is not sufficient to simply place a thin, light, and easily floating material such as a foil on it while moving within the coloring equipment 12, it is preferable to fix it to the base plate with adhesive, tape, or the like.

The mother plate 16 carrying the material 15 to be colored passes between sealing rolls of electrolyte when entering and exiting the coloring equipment 6.

At this time, it is preferable that the material to be colored is not pressed against the seal roll.

A suitable example is shown in FIG. A coloring material 1 is placed on the mother plate 16.
A recess 17 is formed which is deeper than the thickness of 5. As a result, the material to be colored 15 does not come into contact with the seal roll 18.

Although the power supply to the mother plate 16 is arbitrary, since the mother plate enters the coloring equipment 12 intermittently, one composed of leaf springs 19 can be suitably used.

The base plate 16 may be made of any material as long as it has good conductivity and is resistant to colored solutions, but titanium, for example, is preferred. A stainless steel plate may be used as the mother plate 16, but this is not so preferable because it becomes highly insulating when it becomes colored.

It is a front view.

FIG. 4 is a diagram showing a conventional coloring method.

<Effects of the Invention> According to the method of the present invention, it is appropriate to place irregularly shaped objects such as circles and squares, small objects with small dimensions, and thin foils even when producing a wide variety of products in small quantities on a motherboard. In addition to being able to be colored, the small stop is improved.

Furthermore, if a recess is formed in the base plate, the material to be colored can be prevented from coming into contact with the seal roll, thereby preventing damage.
