2. Description of the Related Art Conventionally, a spun yarn has been wound on a bobbin by a winding device, and the state of the wound body on which the yarn has been wound has been inspected.

[0003] Heretofore, conventionally, when inspecting the wound body on which the yarn has been wound as described above, each wound body on which the yarn has been wound is individually taken out, and each wound body is taken out. Various items such as the number of filaments constituting the yarn and the denier of the wound yarn are checked.

On the other hand, in recent years, an automatic winding device has been used to wind the yarn spun as described above on a bobbin.

[0005] In such an automatic winding device, the winding speed is accurately controlled by an inverter or the like, and the length of the yarn to be wound is also accurately controlled by a timer.

Accordingly, in each of the wound bodies wound by the automatic winding apparatus as described above, generally, the number of filaments constituting the yarn wound around the wound body due to breakage or the like is abnormal. Occurs, or abnormalities occur in the denier of the yarn wound on the wound body due to uneven discharge of the gear pump when spinning from the spinneret, and oil is applied to the yarn spun from the spinneret by the oiling roller. At this time, the adhesion of the oil agent was uneven.

However, conventionally, when inspecting a wound body in which the yarn is wound as described above,
As described above, each wound body on which the yarn was wound was individually taken out, and various items were checked for the yarn wound on each wound body. A lot of time is required, a series of operations after winding the yarn by the automatic winding device cannot be automated, and the work efficiency after winding the yarn by the automatic winding device is significantly reduced. was there.

For this reason, conventionally, when inspecting the wound body on which the yarn has been wound as described above, it has been practiced to take out only an appropriate wound body and perform a sampling inspection. Inspection is still time-consuming, and only partial sampling inspection is performed, so that inspection leaks occur, and a sufficient number of wound bodies with abnormalities in the number of filaments constituting the yarn and denier of the yarn are found. Can not
There is a problem that a sufficient inspection cannot be performed.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems when inspecting a wound body on which a yarn has been wound by an automatic winding device or the like.

That is, in the present invention, in each of the wound bodies wound as described above, the denier in the yarn wound around each wound body and the filament constituting the wound yarn An object of the present invention is to make it possible to continuously and easily inspect for abnormalities in the number of components in a series, and to automate a series of operations after winding the yarn by an automatic winding device or the like, thereby significantly improving the operation efficiency. It is assumed that.

[0011]

According to the present invention, in order to solve the above-mentioned problems, when inspecting the wound body 10 on which the yarn 11 is wound, each of the wound bodies 10 is sequentially placed. After being transferred, the weight of each of the wound bodies 10 is continuously measured, and the measured weight of each of the wound bodies 10 is compared with the weight of a predetermined allowable range of the wound body 10. The weight deviation R in the yarn body 10 is obtained, and an abnormality in denier in the yarn 11 wound around each of the winding bodies 10 and an abnormality in the number of filaments constituting the wound yarn 11 are detected. .

Here, the weight of each of the winding bodies 10 is continuously measured as described above, and the measured weight of each of the winding bodies 10 and the weight of the winding body 10 within a predetermined allowable range are determined. In comparison, it is inspected whether the yarn 11 wound around the wound body 10 has a denier abnormality.

Next, when the weight deviation R in each of the winding bodies 10 is determined to detect an abnormality in the number of filaments constituting the yarn 11 wound on each of the winding bodies 10,
Each of the wound bodies 10 simultaneously wound by the same winding device
Is calculated, and the weight deviation R in each winding body 10 is obtained by comparing the average weight X with the weight Xi measured in each winding body 10 as shown in the following equation. R = | X-Xi |

Then, the value of the weight deviation R of each of the wound bodies 10 obtained as described above and the weight average X of each of the wound bodies 10 are divided by the number n of the filaments constituting the yarn 11. By comparing the value (X / n) with the value (X / n), it is detected whether or not the number of filaments constituting the yarn 11 wound on each of the winding bodies 10 is abnormal. That is, when the value of the weight deviation R in the wound body 10 is larger than the value of (X / n), the number of filaments constituting the yarn 11 wound on the wound body 10 is abnormal. You can see that there is.

The weight data of each of the wound bodies 10 measured in this way is stored in a master file, and is compared with the weight of the wound body 10 in the previous doff previously wound by the same winding device. It is preferable to do so. This is due to the fact that the variation over time of the discharge unevenness of the gear pump when spinning from the spinneret is small in experience,
This is so that, when an abnormality occurs in the number of filaments in the yarn 11 wound around the wound body 10, it can be detected appropriately and promptly.

[0016]

According to the present invention, the winding bodies 10 on which the yarns 11 are wound as described above are sequentially transferred, and the weight of each winding body 10 is continuously measured. Winding body 1
By comparing the weight of the wound body 10 with the weight of the wound body 10 in a predetermined allowable range, and comparing the weight of each wound body 10 with the weight of the wound body 10 in the same position of the previous duff, An abnormality of denier in the yarn 11 wound around the wound body 10 and an abnormality of the number of filaments constituting the wound yarn 11 are detected.

For this reason, the method of the present invention allows the yarn 1
Inspection of each of the wound bodies 10 on which the yarn 1 was wound was performed. As in the conventional case, the wound bodies 10 on which the yarn 11 was wound were individually taken out, and each of the wound bodies 10 was wound. There is no need to individually inspect the number of filaments constituting the yarn 11 and the denier of the wound yarn 11, and the winding yarn 11 is formed for each of the wound bodies 10 on which the yarn 11 has been wound. The number of filaments
The denier of the wound yarn 11 can be inspected continuously and easily.

As described above, the value of the weight deviation R of each wound body 10 and the value of the weight average X of each wound body 10 divided by the number n of filaments constituting the yarn 11 (X /
As a result of comparison with n), when there is an abnormality in the number of filaments constituting the yarn 11 generally wound on the wound body 10, the weight deviation R in the wound body 10
Is larger than the value of (X / n),
When there is no abnormality in the number of filaments constituting the yarn 11 wound on the wound body 10, the value of the weight deviation R in the wound body 10 becomes smaller than the value of (X / n).

For this reason, based on the result of comparing the value of the weight deviation R in each wound body 10 with the value of (X / n), the yarn 11 wound on each wound body 10 is determined. It was possible to easily determine whether or not there was an abnormality in the number of filaments composing.

Further, in order to determine the abnormality in the number of filaments in the next doff and thereafter reliably and promptly, the weight of the wound body 10 at the same position in the previous duff is compared with the weight of (X / n) or more. If there is a difference,
It is determined that there is something wrong.

Although not shown, in this embodiment, in order to examine the unevenness of adhesion of the oil agent on each of the above-mentioned wound bodies 10, the water content of each of the wound bodies 10 is measured.
Based on the result of the moisture measurement, it was determined whether the oil agent attached to the yarn 11 wound around each of the wound bodies 10 was normal or abnormal.
