DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically performing a surface treatment operation of a yarn package in a fiber manufacturing industry.

[0002]

2. Description of the Related Art Generally, a synthetic fiber yarn is melted and spun, and then wound around a paper tube by a winder (hereinafter, the wound product is referred to as a package). The yarn quality of the part around 500 m from the winding end of the package is poor due to the fluctuation of the tension at the end of winding, and this part is usually unwound and removed, and the yarn end is removed from the package surface. Fixed to. This work is generally called surface treatment. Then, for example, in the above-mentioned surface treatment operation for polyester filament yarn, JP-A-63-1086
There is a device disclosed in Japanese Patent No. 39. With this device, the surface layer of the package is vacuum-sucked by the yarn end suction tube while rotating it around the axis of the package in the unwinding direction, and the yarn end is released from the surface layer of the package. It moves in parallel with the axis of the package, continuously unwinds and sucks the surface layer for a certain period of time, then ties the threads on the surface layer and cuts the part to remove the defective part.

[0003]

However, in the apparatus disclosed in the above-mentioned Japanese Patent Laid-Open No. 63-108639, processing is performed only when the yarn tube length of the package is constant and the diameter dimension of the package is constant. Was possible. For this reason, the surface treatment can be performed only for one type of package shape, and for the packages other than this shape, for example, the package having a small diameter in which the yarn is broken during winding by the winder, the surface treatment is manually performed. Therefore, a great deal of labor is required for this process. Further, regarding the distance between the yarn end suction tube and the package when releasing the surface layer, as shown in FIG. 4 (a), in the triangle with the package diameter being the base side α and the distance being the height β, both base angles are If θ ₁ and θ ₂ are not more than the specified angle, the end γ of the package will collapse when unwinding.
It is necessary to make the distance more than a certain distance. However, since the above device moves the yarn end suction tube in parallel with the package shaft core to unwind the surface layer, there is no yarn end suction pipe on the package axis line as shown in FIG. In order to make the angle θ ₂ equal to or larger than the predetermined angle, it is necessary to make the distance longer than in the case where the yarn end suction tube is on the axis, and as a result, the device becomes large. In addition, in a weaving shop that is a user, many packages are manually or automatically mounted on a creel stand in preparation for weaving, and the threads are unwound from these packages and wound on a beam. Of the both end surfaces of the, the twisting of the yarn at the time of unwinding differs depending on which side is attached to the creel stand with the creel stand side,
Depending on the type of package and the intended use of the yarn, the front and back directions of the package are distinguished and mounted on a creel stand. At that time, when the yarn end is manually pulled out from the package, it is easier to perform the work if the yarn end is fixed to the front side. However, in the device disclosed above, the yarn knot can be knotted only at a position of about 20 mm from the surface of the package in the yarn end fixing process after unwinding the surface layer, and the yarn end fixing position is always constant. In the above-mentioned operation of distinguishing, the yarn end may be located at the back side of the creel stand, so that workability when taking out the yarn end was poor.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an apparatus capable of automatically treating the surface layer of a yarn package having a plurality of shapes.

[0005]

In order to solve the above-mentioned problems, the present invention provides a conveying section for conveying a yarn package formed by being wound around a paper tube, and a positioning section for positioning the conveyed yarn package. And a processing unit for removing defective surface layer yarns of the positioned yarn package, and a switching unit for adjusting the advance distance according to the length of the paper core.
Push the yarn package along the axis of the yarn package.

It is characterized in that the processing section is composed of an unwinding mechanism and four mechanisms of a yarn end fixing mechanism which is provided so as to be movable back and forth in the front and back directions of the package and fixes the yarn end at a predetermined position of the package.

[0006]

The operation of the present invention will be described below. Claim 1
According to the invention of claim 1, first, the yarn package is conveyed by the conveying unit, and the yarn package conveyed by the positioning unit is positioned at a predetermined position. Then, the yarn package is rotated in the unwinding direction about its axis by the rotation mechanism of the yarn processing section. On the other hand, the suction port is located near the outer circumference of the yarn package by the moving mechanism of the yarn end unwinding mechanism.
Then, while rotating the yarn package, the yarn end on the surface layer of the package is sucked by the suction port of the yarn end unwinding mechanism, after which the rotation of the rotating mechanism is stopped and the suction port is extended on the extension line of the package axis. The yarn is moved to the position and the yarn is continuously sucked by the suction port to unwind the defective yarn portion. After the unwinding, the yarn end fixing mechanism is moved back and forth in the front and back direction of the package and moved to a predetermined yarn end fixing position. Then, the yarn after the unwinding is adhered and fixed by the adhesive seal, and the yarn in the defective portion is cut. Then, the vacuum suction of the yarn end suction means is stopped.

According to the invention described in claim 2,
Since the pushing-out mechanism is provided in the processing section, the positioned yarn package can be moved along its axis, and as a result, the fixed position of the yarn end after the surface treatment can be arbitrarily set along the axis of the yarn package. Can be set.

By the way, when the synthetic fiber is wound by a winder, it is wound into a package having several widths depending on the demand of the user such as a weaving shop. When one package is wound up into N packages per spindle, this is generally called N separation, and when the number of N is doubled, the paper tube length and the winding width are halved. The general value of N is 2, 4, 6, 8, etc., but it is 4 due to the mechanical limitation of the winder, the frequency of doffing, the length of the warp thread in the weaving shop, etc.
Fibers with 8 or 8 fibers are often used. Also,
