Embodiment Construction

[0052] 1 is a block diagram showing an example of an electrical configuration of a system of the present invention, FIG. 2 is a schematic layout diagram of the system of FIG. 1 , and FIG. 3 is a flowchart for illustrating the operation of the system of FIG. 1 . In this example, the thickness (or non-uniform thickness) of a continuously moving filter tow (ribbon-shaped tow) is detected. The filter tow (or tow band) comprises a plurality of filaments. That is, the filter tow is formed of a plurality of filaments that are bundled, arranged adjacent to each other, and overlapped to form a layer. Therefore, the degree of adjacency or overlap of the filaments fluctuates as the filaments move, and unevenness in thickness of the filter tow tends to produce defective products.

[0053] As shown in Figure 2, on the front side of the filter tow 1 moving continuously from the lower side to the upper side, a line sensor (imaging device) 2 is arranged at a predetermined viewing angle, and ...

Abstract

An automatic judging device and method for precisely judging the adequateness of the width, thickness, and stain of a continuously moving fiber aggregate. A fiber aggregate such as filter tow continuously moving on the front side of a background plate is imaged with a line sensor. Characteristic information including defect information on the thickness, width, and stain of the fiber aggregate is detected according to the generated video signal, and the defect information is extracted to judge the adequateness of the fiber aggregate. For example, the video signal is fed to a noise removing circuit (6a), and a defect signal concerning the thickness is extracted. On the basis of the extracted signal and a reference signal concerning the information, a judging circuit (7) judges the adequateness of the defect information. If the fiber aggregates is judged to be defective, an annunciating circuit (8) annunciates it. The video signal is clamped by a clamp circuit (5b), and defect information on the fiber aggregate may be extracted from the clamped video signal. The characteristic information or the defect information can be given to an external computer and used for process control.

Description

technical field [0001] The present invention relates to an automatic discriminating system that detects characteristic information including defect information of a continuously moving aggregated fiber belt (for example, a fiber bundle such as a filter tow or a fiber assembly), and can be used to Quality control of aggregated fiber strips over time of defect information or time sequence (TSEQ) fluctuation information; and, the present invention relates to an automatic discrimination method. Background technique [0002] A video signal (image signal) from the imaging device is used for quality control and for discriminating whether an inspection object is defect-free or defective. For example, the specification of Japanese Patent No. 3013903 (Patent Document 1) discloses a defect sensing device for detecting a defect on an edge of a plate glass having a shape obtained by bevelling the edge. A seam surface, wherein the device detects on the edge of the glass placed horizontal...
