【Example】

 Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. 1 is a perspective explanatory view showing an outline of an apparatus according to the present invention, FIG. 2 is a block diagram schematically showing a processing flow in the apparatus according to the present invention, and FIG. 6 is a flowchart showing a series of processes for each color determination mode.

On the drawing, what is designated by reference numeral 1 is a handy type colorimeter. A measurement head is provided at the tip of the colorimeter 1, and the measurement head is brought into contact with a measurement sample (in this embodiment, a dyed product D made of dyed fabric) The reflected light of is measured. In the colorimeter 1, the color of the dyed product D is digitized based on the CIE1976 color matching function approximation, and this numerical data is transmitted to the terminal T via the communication interface 11 (communication cable in this embodiment). Is being transmitted. The terminal T is composed of a keyboard, a display, a voice indicator, a printer, and a CPU arithmetic processor, which will be described later.

A keyboard designated by reference numeral 2 is a keyboard exclusively for color determination, which is arranged on the upper front part of the terminal T. The main function of the keyboard 2 is that a plurality of color determination modes can be selected. In this embodiment, three determination modes (stain determination, medium rare determination, Anti-rose determination) is assigned to the keyboard 2. In the dyeing determination mode out of these three color determination modes, the color difference determination between the sample dyed product D ₀ and the dyed processed dyed product D ₁ is performed, and in the medium rareness determination mode, the width of the dyed processed dyed product D 1. The color difference determination in the direction is performed, and in the anti-separation determination mode, the color difference determination in the length direction of the dyed product D that has been dyed is performed. Here, the color difference is a numerical representation of the color difference, and the color difference determination is performed using the numerical data transmitted from the colorimeter 1. In the present embodiment, the Lab colorimetric color difference formula (L is lightness; a and b are chromaticity = color characteristics that combine hue and saturation) is adopted, and three attributes of color (lightness, hue, The difference in saturation is represented by a composite vector. Further, in the medium rareness determination and the conflict determination mode, the determination criteria for determining the color of the dyed product D are set more finely and in stages, and the standard determination criteria and the special determination criteria 1 to 4 are set. It consists of 5 stages. These criteria are also assigned to the keyboard 2 and can be arbitrarily selected. The number of such color determination modes and determination criteria can be increased or decreased as necessary, and the number corresponding to that number is assigned to the keyboard 2, and a program corresponding to the processing procedure is stored in the CPU arithmetic processing unit described later. It may be written in a memory (not shown). Further, the keyboard 2 is assigned with a key for outputting a calibration instruction to the measuring head of the colorimeter 1 and a key for scrolling and displaying a plurality of colorimetric data.

The reference numeral 3 indicates a liquid crystal display type display, which is arranged on the slope between the keyboard 2 and the upper portion of the terminal T. The display unit 3 displays the operation procedure necessary for measuring the color of the dyed product D and the pass / fail judgment result of the color of the dyed product D. In the former operation display function, a selection instruction of the color determination mode assigned to the keyboard 2 is given, and a plurality of dyed products D to be colorimetrically determined according to the color measurement procedure of the selected color determination mode. Are sequentially specified at a predetermined timing. In the latter judgment result display function, the result obtained by performing arithmetic processing on a plurality of colorimetric data sequentially measured by the colorimeter 1 according to the above procedure is a pass (OK) or a fail (NG). It is displayed by either of the judgments.

A reference numeral 4 designates a voice indicator, which is arranged in the upper rear part of the terminal T. The voice indicator 4 realizes almost the same function as that of the display device 3 by voice output, and when used in combination with the display device 3, the color determination operator can more reliably perform the inspection. In the voice indicator 4, several kinds of voice messages registered in advance in a memory in a CPU arithmetic processing unit, which will be described later, are output as voices at the same timing as the screen display of the display 3. The output time of this voice output is arbitrarily set according to the processing content, and the voice output can be stopped midway by pressing a predetermined key (for example, the input key or list key of the keyboard 2). .

What is designated by reference numeral 5 is a printer, which is arranged in the upper rear part of the terminal T. The printer 5 prints colorimetric data and color difference data measured by the colorimeter 1. By collecting and analyzing the printing results, it becomes possible to statistically perform color management of the dyed product D 1.

Reference numeral 6 indicates a CPU arithmetic processing unit composed of a well-known microprocessor, which is built in the terminal machine T. As shown in FIG. 2, the CPU arithmetic processing unit 6 is connected to all the above-mentioned components (colorimeter 1 to printer 5) and controls the entire color determination process. In the CPU arithmetic processing unit 6, a plurality of colorimetric data measured by the colorimeter 1 are compared and calculated, and the color difference data is calculated. Then, based on a predetermined pass / fail judgment condition pre-installed in the program written in the memory (not shown) in the CPU arithmetic processing unit 6, it is judged whether or not the color difference data satisfies the judgment condition. The pass / fail of the color of the processed and color-measured dyed product D is determined. This pass / fail judgment result is converted into an image signal and displayed on the screen of the display device 3, and at the same time, the judgment result is converted into an audio signal and output as audio to the audio indicator 4. In the present embodiment, the pass / fail judgment conditions are pre-stored in the memory. However, the optimum pass / fail judgment conditions having a learning function can be formed by parameterizing these judgment conditions and inputting / correcting them from the keyboard 2. Is also possible.

Here, the flow of processing in the above three color determination modes will be described based on the flowchart of FIG. First, in the dyeing determination mode, when the color measurement of the sample dyed product D ₀ and the dyed dyed product D ₁ are sequentially performed using the colorimeter ₁ , the color difference between the dyed product D ₀ and the dyed product D ₁ is detected. Is calculated by the CPU arithmetic processing unit 6, and the pass / fail judgment result of the color of the dyed product D ₁ is output. Next, in the medium rare judgment mode, one of the five judgment criteria is selected, and the dyed product D dyed using the colorimeter 1 is dyed and processed along the width direction at the central portion Dc, left. When the colors of the part Dl and the right part Dr are sequentially measured, the color difference between the central part Dc-the left part Dl, the central part Dc-the right part Dr, and the left part Dl-the right part Dr is calculated by the CPU arithmetic processing unit 6, respectively. The pass / fail judgment result of the color of the dyed product D is output. Finally, in the anti-bar judgment mode, one of the five judgment criteria is selected, and the dyed product D dyed using the colorimeter 1 is sampled along the length direction Di ( (Up to 20 pieces) are sequentially measured, the color difference between the first sample D ₁ and the i-th sample Di (i = 2 to maximum 20) is calculated by the CPU arithmetic processor 6, and the color of the dyed product D 1 is calculated. The pass / fail judgment result of is output.

As described above, in the apparatus of this embodiment, the color pass / fail judgment result of the dyed product D can be easily obtained only by operating according to the processing procedure of each color judgment mode, and the work efficiency in the color inspection is significantly improved. .

The embodiment of the present invention is generally as described above, but the present invention is by no means limited to the above-mentioned embodiment, and various modifications can be made within the scope of the “claim for utility model registration”. In the apparatus of this embodiment, for example, the keyboard T, the display unit 3, the voice indicator 4, the printer 5, and the CPU arithmetic processor 6 are used.
