Abstract

PURPOSE:To enable a winding form to be accurately automatically judged in a twisting machine or the like by radiating light beams on the surface of yarn layer in a winding yarn package to supply beams reflected from two positions to the input of an analyzer as light information. CONSTITUTION:Irradiant light PH1 from a light source 1 is irradiated over a width W larger than the radius of an end face of a package P. On the other hand, image sensors 5a, 5b are focused to read reflected light beams PH2a, PH2b on straight lines A, B approximately in the radii of two positions spaced by a constant interval from each other, and a distance l between A and B is set to one which is not spanned by dust or the like, for example to about 2-5mm. This light information is collated with a certain pattern in an analyzer 7 to check defective winding form like cob-webbing, defective end face, wrinkles, blister or annual ring winding.

BACKGROUND OF THE INVENTION Packages wound by a winding machine such as an automatic wine gooter or a thread twister are mixed with packages with poor winding shapes due to various reasons. For example, as a typical example, in the package end face (T) shown in FIG.
When the spinning bobbin shown in Figure (2) finishes winding or the yarn breaks, the yarn end (Yl) falls from the package end surface and winds around the winding tube (K) or enters the yarn layer. A falling package (P2), a package called Kikumaki (G) due to shortening of the traverse at the beginning of winding shown in Fig. 9 (1), a decrease in tension due to slip, or a bulge (P3).
), or a stepped part (N
) There are various types of puff cages with poor winding shapes, such as a package called a puffy ball (P4), which has a defective spinning bobbin shape, and a ring-wound package (P5) caused by fluctuations in unwinding tension due to a defective spinning bobbin shape.

That is, the optical signal obtained by the image sensor (5a) is converted into an electrical signal, which is then passed through the noise remover fl (9a) shown in Figure 1 and converted into a signal of a size suitable for processing by the amplifier (10a). The signal is then converted into a digital signal via an analog-to-digital converter (lla).The signal is input to a normalization circuit (12a) and normalized to make it suitable for comparison with a set level. The signal is input to a level comparator (13a), compared with a preset level, and further input to a calculation device (14) together with the signal obtained at the other measurement position.

For example, assume that the electric signal (Ll) after charging and conversion of the reflected light imaged by the image sensor (5a) is as shown in FIG. 3 (Ll). The distance (S) indicates the distance (S) from the measurement position (A) on the end face of the package in FIG. The electrical signal (Ll) passes through a noise remover (9a) and becomes a signal (Ll). Here, the low level portion (15) corresponds to a normal yarn layer plane portion lζ on the end face of the package, and the protruding high level portion (16) corresponds to a defective portion such as twill drop or bulging formed on the package surface. do.

In the above example, the level (18) of the signal (L3) is higher than the set level (V), but depending on the defect state of the thread layer surface, it may be at the standard level as shown in Fig. 4, that is, when the thread is normal. A portion (21) with a lower level than the optical information level (15) on the layer surface may occur, and in such a case, the reference level (Vl) is set to be lower than the standard level (15).
15) Set it to a smaller value.

That is, as shown in Fig. 7 (a), the impurity (Xl) is located at the position (A).
When the signal line (L4a) in Figure 1 is reached, the signal (25) in Figure 8 (A) is output, and the other signal line (L4b) is outputted with the other signal (25) in Figure 8 (A). 26) is issued. These are input to the arithmetic unit (14). The arithmetic unit (14) determines that the package is defective only when both of the above two signals are "1" signals, and outputs a "1" signal, that is, a wound-shaped defective package signal.

Furthermore, the para-needle (P) rotates, and as shown in Figure 7 (2), the thread α1) that has fallen off the twill passes to both positions A and B, and the impurity (X2) reaches position A. Then, the signal at position A becomes an rlJ signal with high level parts (27) and (28) due to impurities and threads that have fallen off the twill, as shown in Fig. Level part (
29), and since both are "1" signals, a determination signal "1" is output, and for the first time, it is determined that the package has a defective winding shape. The above discrimination signal “

In addition, in FIG. 8, the distance (Sl) is the impurity (XI
), and furthermore, the distance (82) (
84) (85) (S6) corresponds to the distance from the innermost thread waste on the end face of the panocage of the thread that has fallen off the twill, for example, A,
If a level (30) protruding from the standard level always occurs at a distance (S2) at position B 1ζ, it can be determined that there is a poor winding over the entire circumference of the package, and (I
It is possible to infer that it is a package of bulge balls and tree ring rolls shown in (V) and (V). In addition, if the above discrimination signal "1" is partially output during one revolution of the package, it can be assumed that the package is a twill-dropped package or an end-dropped package, and the type of package with poor winding shape can be roughly classified. In the above embodiment, the Kaede measurement positions (A) and (B) are simultaneously read by separate image sensors, and the two obtained optical information are simultaneously processed by processing devices arranged in parallel. In the case shown above, a single image sensor is provided at one location, and the first
The same determination as described above can be performed using the illustrated processing units (9a) to (13a) as one. That is, first, a single image sensor reads the position (B) in FIG. 6, and the obtained optical information is processed in the same manner as described above, and the first signal is output as a "1" or "0" signal as shown in FIG. Once the information is input to the memory in the arithmetic unit (14) shown in the figure, the package is rotated by a certain angle in the direction of the arrow (24), and when the line at position A reaches position B, the image sensor The optical information obtained is processed in the same manner as above, and the result is still "1".
Alternatively, a signal of "0" is input to the arithmetic unit (14), and the discriminating signal is output as described above by arithmetic operation with the previously stored signal of one pitch (6).

Furthermore, in the above embodiment, as a typical example of a package with a defective winding shape, a defective portion is generated on the end surface of the package, but the defective portion is generated on the outer circumferential surface of the thread layer of the package, that is, the surface (31) in FIG. 9(1). It is also possible to detect defective parts, such as a step-wound package with steps in the direction of the package axis, or a ribbon-wound that occurs because the traversing yarn passes through the same thread path. This can be done by setting the reading position of the image sensor in the generatrix direction lζ on the outer peripheral surface of the package.

As described above, according to the present invention, it is possible to determine whether the winding shape of the package is good or bad by irradiating light onto the end face of the package and using the reflected light, and it is possible to identify defective packages that were overlooked by visual inspection. Check errors due to impurities other than shapes can be prevented, and accurate automatic discrimination is possible.
