As is well known, the collected cocoons are handed over to the silk miller after removal of defective cocoons unsuitable for silk spinning by the cocoon producers. There are perforated cocoons, internally contaminated cocoons, externally contaminated cocoons, fluffy cocoons, thin-skinned cocoons, coated cocoons, malformed cocoons, and floating cocoon layers. However, internally contaminated cocoons are difficult to distinguish by mere observation, and can be easily sorted by cocoon producers. In reality, it is difficult to carry out sufficient sorting, and sorting work is carried out in silk mills that mainly targets internal contamination.

These internally contaminated cocoons are usually caused by rough handling of the surface after cocooning, resulting in damage to part of the body of the silkworm or untransformed cicada silkworm, which stains the inside of the cocoon layer. Contaminated cocoons are broadly classified into cocoons that die after cocooning and their sewage stains the inside of the cocoon layer. The former type of contaminated cocoons deteriorate the color of the raw silk or cause the cocoon silks to stick to each other, causing them to fall off. An increase in the number of cords can cause a decrease in efficiency due to yarn failure, and the latter, so-called dead cocoons, have a small number of cocoon yarns and a small amount of cocoon yarn, and the inner layer of cocoon yarns is very thin, so there are many dropped strands, and the number of cocoon yarns decreases. This sorting is a major problem even in silk mills, as it not only reduces reeling efficiency, such as low strength and elongation, but also reduces the quality of raw silk, such as knots and strength and elongation. There is. In particular, raw silk due to internal contamination remains brownish even after scouring, which is of great concern to weavers.Furthermore, the number of internally contaminated cocoons has increased in recent years. It follows a trend.
? θ Traditionally, in silk mills, sorting work has been carried out mainly for internally contaminated surfaces. Let me,
This method used to detect internal contamination by shining the light from a fluorescent lamp through the surface, but this method was less efficient and required more skill than other simpler and more efficient methods. Development of a method was desired.

In addition to fluorescent lamps, it has also been proposed to irradiate ultraviolet rays of 330 to 380 millimicrons, as seen in Japanese Patent Publication No. 31-8306. It has been proposed to use light with a wavelength of 575 mm to 600 mm that does not include the ultraviolet region or in combination with near ultraviolet rays for the inspection of chicken eggs.
These devices use transmitted light to observe the quality of the inspected object based on the appearance of shadows on the inspected object, and none of these methods go far beyond the range of fluorescent lamps. The inventors of the present invention have conducted extensive research and conducted various experiments in order to obtain a force method that makes it easier to detect internally contaminated surfaces with the naked eye, improves its accuracy, and enables highly efficient cocooning. By irradiating the surface with a parallel beam of laser light from a mixed gas (hereinafter simply referred to as HeNe laser light), internally contaminated cocoons can be easily detected with the naked eye, and the sorting accuracy is significantly improved and efficiency is also increased. Knowing that it can be greatly improved,
The present invention has been obtained.

In the present invention, HeNe laser light identifies internally contaminated surfaces because when the surface is irradiated with HeNe laser light,
eThe cocoon emits uniformly diffused light due to the coherency of the laser beam and the uniform diffusivity of the cocoon itself if the cocoon is of good quality, and the amount of diffused light from the entire cocoon is large. This method takes advantage of the phenomenon that when the inside of a cocoon is contaminated, the HeNe laser light is absorbed by the contaminated part inside the cocoon, and when viewed from the outside, the entire cocoon appears dark and the amount of light diffused from the entire cocoon is extremely small. It is.

Therefore, whether a cocoon that has been irradiated with HeNe laser light is a good product or whether the inside is contaminated depends on whether the cocoon emits uniformly diffused light or whether the cocoon emits extremely little diffused light and the entire cocoon appears dark. This difference is so remarkable that it can be clearly discerned with the naked eye, so it requires less skill than the conventional force method using fluoroscopy using fluorescent light. Therefore, efficiency can be significantly improved. DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the cocoon-pulling method according to the present invention in which a large number of surfaces to be sorted are cocooned in a silk mill or the like will be described with reference to the accompanying drawings.

Now, when the sorted cocoons 16 are lined up on the conveyor belt 1 and the drive wheel 5 is driven, the cocoons 16 are transferred to the left in the figure. It is assumed that at the same time as the conveyance of the conveyor belt 1 is started, the rotating wheels 8 and 9 are also rotated, and the conveyor belt 4 is also started to convey. When done like this, the cocoon 1
5 is transferred from the conveyor belt 1 onto the rotating Galanu cylinder 7, and further transferred onto the conveyor belt 4 and transported. During this time, the cocoons 16 are irradiated with a HeNe laser beam on the rotating glass cylinder 7 to be sorted, and for this purpose the following steps are taken.

That is, the HeNe laser beams 11 and 1V from the HeNe laser oscillators 10 and 10' are reflected by the first reflection plates 12 and 12.
' and is irradiated onto the rotating reflector 13, but since this octahedral rotating reflector 13 is rotated by the rotary drive device 14 at a speed of, for example, 1500 times/minute,
The HeNe laser beam irradiated on the rotating reflector 13 becomes a linear scanning beam that is irradiated onto the second reflecting plates 15, 15', and is reflected by the second reflecting plates 15, 15', passes through the rotating glass cylinder 7, and then passes through the surface. The entire surface on the rotating glass cylinder 7 is irradiated in a scanning line perpendicular to the conveying direction of the glass cylinder 7.
At this time, as mentioned above, a good cocoon shines brightly due to uniformly diffused light. This glow becomes light pink in the case of HeNe laser light. Also, when internally contaminated cocoons exist, HeNe
The entire cocoon appears dark because the laser light is absorbed by the contaminated area. Therefore, since good cocoons shine and bad cocoons turn dark, the difference between good cocoons and bad cocoons can be distinguished very clearly, so even if the surface transfer speed, that is, the sorting speed, is increased, it will not be overlooked, and even if the skilled cocoon is Since it does not require much skill, it can be done easily and efficiently. The selected good cocoons are transferred onto the conveyor belt 4 and transported.
Another example of sorting is to place a surface on a rotating body, irradiate the surface with HeNe laser light while rotating the surface, place a light receiver directly above it, and When the DC voltage of the cocoon is measured, the diffused light from a good cocoon has a much higher voltage than the diffused light from an internally contaminated cocoon, so the difference in these voltages can be used to sort the cocoons.
For example, if you place a DC amplifier after the receiver, and then put comparators A and B after the DC amplifier, the one that crosses the double edge of the level of comparator A and the level of comparator B is considered a good cocoon. Cocoons that only exceed the level of comparator B can be automatically classified as internally contaminated cocoons. Next, the present invention will be explained in more detail with reference to Examples.

That is, when the sorted cocoons are transported at a speed of 7 m/min,
Two workers sorted 2,4501 cocoons per hour into removed cocoons (bad cocoons) and real cocoons (good cocoons). The cocoons selected at this time (
The amount of defective cocoons) is 52 f1, which is the same as the amount of cocoons picked 2.4
The cocoon removal rate was 2.1% for 50g. In this way, 529 defective cocoons were selected and removed from 2,450 g of cocoons, and cocoons 2,39 were recognized as genuine cocoons (good cocoons) by the workers.
Regarding 8g, all of these were inspected for each grain in the column ``Cocoons after selection'', and the amount of defective cocoons of 1461 means that 2,398g of each cocoon that was recognized as real cocoon by the worker was inspected. During the grain inspection, the number of cocoons identified as defective cocoons is 6.1%, and the defective cocoon contamination rate of 6.1% is the number of cocoons 2 and 3 above.
This is the contamination rate for 989. The column ``still selected and removed cocoons'' means the following. In other words, as mentioned above, the worker first selects 52 cocoons from among the 2,450 f1 surfaces, determining that they are defective cocoons.
θ was selected (amount of cocoons selected and removed), but the column ``Selected cocoons'' shows the results of re-inspecting the defective side of this 52g. Among the defective cocoons, 4.6g of cocoons that were originally good cocoons instead of defective cocoons were selected and removed. This shows the proportion of good cocoons mixed in. As can be clearly seen from these test results, the force method of the present invention can remove about three times as many defective surfaces as the conventional force method. ,
It can also be seen that the amount of defective surfaces mixed into the cocoons determined to be good was significantly reduced.

The quality of the defective cocoons mixed into this genuine cocoon is that
The contamination on the surface was extremely low, and it could be said that the cocoons were on the Porter line between good cocoons and bad cocoons, and it is considered that this level of contamination on the surface is unavoidable. Furthermore, it can be seen that the number of good cocoons mixed in the cocoons that were selected and removed as defective cocoons was drastically reduced to the extent that it was hardly a problem compared to the conventional method. For these reasons, the force method of the present invention can very easily distinguish between good cocoons and bad cocoons compared to conventional force methods that use fluorescent lamps or ultraviolet light, and its accuracy is extremely high. Therefore, it does not require much skill,
It has also been clearly shown that work efficiency can be improved.
As explained in detail above, according to the present invention, the cocoons irradiated with a parallel beam of HeNe laser light are uniform due to the coherency of the HeNe laser light and the uniform diffusivity of the cocoon itself. It shines by emitting diffused light, and the internally contaminated cocoon is HeN.
The e-laser light is absorbed by the contaminated part, turning the whole cocoon dark, and the difference between good cocoons and internally contaminated cocoons can be very clearly distinguished, so the sorter can easily sort the cocoons without much skill. Even if the processing speed is increased, it is possible to sort without overlooking anything, so work efficiency can be significantly improved, and the rate of sorting contaminated surfaces can be improved to almost 100%.
This is an extremely excellent invention that will greatly contribute to the industry in the current situation where internally contaminated cocoons are increasing.
