Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package carrying system for carrying out inspections and the like while carrying synthetic fiber packages processed by a draw false twisting machine and the like.

[0002]

2. Description of the Related Art For example, a drawing false twisting machine receives a yarn supply package from a spinning factory, performs a drawing false twisting process, and winds it into a synthetic fiber package. The doffing of this synthetic fiber package is automatically performed by an auto doffer. This auto doffer cuts the yarn being wound, sucks the yarn end, transfers the synthetic fiber package to the package carrier equipped around the draw false twisting machine, and installs the empty paper tube instead. , Thread hooking and bunch winding. The synthetic fiber package transferred to the package carrier is automatically conveyed to the drive end of the draw false twisting machine, and transferred to a pin track or the like prepared in advance by the transfer device.

The synthetic fiber package thus transferred to the pin track is transported to a predetermined place, and then shipped through an inspection process and a packing process.

By the way, the processing degree of the synthetic fiber package after the drawing false twisting machine is not always uniform, and a synthetic fiber package in which untwisted portions and the like frequently occur due to differences in mechanical conditions and setting conditions of each weight. May be included. The appearance of this untwisted portion often appears in a fixed cycle, and the presence and extent of the untwisted portion can be clearly seen when the cloth is used.

Therefore, a certain amount of yarn is taken from each synthetic fiber package, and the yarns are spliced one by one to form a continuous yarn, which is subjected to test knitting by a tubular knitting machine, and a large number of untwisted portions are produced by this trial knitting fabric. A check is made for the presence of defective packages.

[0006]

However, the sampling of the yarn from the synthetic fiber package and the supply to the trial knitting machine have been performed manually. That is, the synthetic fiber package is carried together with the pin track to the trial knitting machine, and a predetermined amount (about 50 m) of the yarn of each synthetic fiber package hung on the pin is manually fed into the feeder of the trial knitting machine, and the yarn end after cutting is cut. The manual work of splicing the yarn to the next synthetic fiber package was performed. Therefore, there is a problem that it takes as long as 8 hours for four people to collect the yarn from the synthetic fiber package for one lot in an ordinary factory and complete the trial knitting. Further, when a synthetic fiber package is automatically doffed by an auto doffer, a device for the doffing operation touches the yarn, so that the yarn end may be damaged and damaged. If such a damaged yarn end is sampled and an inspection such as trial knitting is performed, the evaluation cannot be performed accurately. Further, in a draw false twisting machine, oil is usually applied to a yarn before winding by an oiling device. However, when doffing with an automatic doffer, the yarn being wound is cut, and the doffing is performed while sucking the end of the yarn.Therefore, if the sucking force is weak, the yarn may wind around the oiling device. It is designed to cut and suck after removing.
Therefore, since the first portion of the surface layer yarn is a yarn that is not oiled, the quality may not be accurately evaluated by trial knitting or the like. Therefore, until it becomes a thread that does not have a risk of being scratched, and if it becomes a regular thread that has been oiled as necessary,
I also carried out the troublesome work of unwinding and discarding the surface threads by hand.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to automatically remove an abnormal yarn from a package in preparation for inspection. It is to provide a package transport system capable of

[0008]

A package conveying system for solving the above problems is provided with a surface layer unwinding station for unwinding and removing the surface layer yarns of a package on a conveying line where packages are sequentially conveyed. There is a sampling station after which a yarn is drawn out if necessary.

[0009]

Operation: Before the package is shipped, the appearance, twill and fluff are inspected while being conveyed on a peg tray while being conveyed by a conveyor. If a surface layer unwinding station is provided on this conveying line, the yarns that are damaged during the doffing of the auto doffer and the non-regular yarns not coated with oil are automatically removed. Further, a sampling station for pulling out regular yarns from each package and splicing the yarns is provided further downstream, which is automatically connected to a trial knitting inspection process or the like.

The suction force of the soccer 14 is set to be larger than that of the suction mouth 13. Then, when the soccer 14 rises as shown by the arrow b, the unwinding direction of the yarn becomes the axial direction of the synthetic fiber package P, and it is unwound rapidly regardless of the rotation of the synthetic fiber package P and a considerable amount of the yarn is sucked. It is carried to a dust box (not shown). In addition, soccer 14
When is rotated as indicated by arrow c to the position indicated by the chain double-dashed line, the yarn can be introduced into the yarn guide 20 and the yarn joining device 15 described below.

The sampling station S2 of FIG. 1 is provided with a yarn splicing device 15, a trial knitting machine 16 is connected to the sampling station S2, and the continuous yarn spliced by the yarn splicing device 15 is introduced into the trial knitting machine 16. To be done. As shown in FIG. 2, in the sampling station S2, a suction pipe 17 on the lower side of the peg tray 3, an installation base 18 of a standard package SP on which standard quality yarn is wound, and a color package on which color yarn is wound. CP installation base 19, thread guides 20, 21, 22 and clamp cutters 23, 24, 2
5 and the like are provided.

Further, as shown in FIG. 3, the yarn joining device 1
The main body 15a of No. 5 is located on the far side of the yarn path, and the levers (not shown) located above and below the main body 15a take up the yarn ends of the two yarns into the main body 15a by a turning operation during yarn splicing.
After twisting with an air nozzle to create entanglement of filaments and splicing them together, excess yarn ends are cut with a cutter.

The trial knitting machine 16 connected to the sampling station S2 includes a feeder 27 and a first tubular knitting device 28.
And a second tubular knitting device 29. Feeder 27
Has a drum for winding the yarn after the yarn splicing, draws a predetermined amount of the yarn and stores it, and continuously supplies the yarn to the tubular knitting devices 28 and 29. The tubular knitting devices 28 and 29 knit a single yarn in a tubular shape, and since it is necessary to change the size of the stitches depending on the thickness of the yarn, the first tubular knitting device 28 for the fine stitches and the thick second Either the tubular knitting device 29 is used.

Returning to FIG. 2, the clamp cutters 24, 25
Is for cutting the yarn from the standard package SP or the color package CP and holding the yarn on the package side, and further moves as indicated by arrows d and e to guide the yarn to the yarn joining device 15. The clamp cutter 23 cuts the yarn from the synthetic fiber package P to the trial knitting machine 16 and holds the yarn on the trial knitting machine 16 side. Then, the yarn on the side of the synthetic fiber package P is sucked from the top of the bobbin B by the suction of the suction pipe 17, and the yarn end is hung inside the bobbin B.

The surface layer yarn knotting station S3 is provided with a knotting device 30 for sucking and grasping the yarn end in the bobbin to make a knot on the outer periphery of the package.

Next, the operation of the main part of the above-described package transfer system will be described with reference to FIGS. 4 and 5 show a yarn splicing process between the synthetic fiber packages P. Figure 4
In (a), a new synthetic fiber package P is supplied to the unwinding station S1, and the sampling station S2
Then, the synthetic fiber package P is pulled out toward the trial knitting machine 16. The synthetic fiber package P supplied to the unwinding station S1 is rotated together with the peg tray 3 by the rotating device 12, and the yarn end of the surface layer is sucked by the suction mouth 13. The sucked yarn end is traversed by the rotation of the synthetic fiber package P.

In FIG. 4B, the suction mouse 1
The yarn end traversing at 3 has been sucked into the football 14. Then, when the soccer 14 rises as shown by the arrow b, the yarn of the synthetic fiber package P is rapidly unwound, and a considerable amount of the yarn passes through the soccer 14 and is thrown into a dust box (not shown). In this way, the threads that were damaged during doffing with the auto doffer, and the non-regular threads that had not been oil-coated with the threads that were removed from the oiling device were removed in advance to make them regular oil-coated threads. If this is done, the test knitting will be performed using regular yarns, and the quality will be accurately evaluated.

The yarn of the synthetic fiber package P at the sampling station S2 in FIG. 4B is cut by the clamp cutter 23, and the yarn reaching the trial knitting machine 16 is held.
The yarn end on the side of the synthetic fiber package P is pulled by the suction pipe 17, sucked into the bobbin B, and hung down. Then, as shown in FIG. 5, the synthetic fiber package P of the unwinding station S1 moves to the sampling station S2, and the yarn reaching the soccer 14 is introduced into the yarn guide 20 and the yarn joining device 15. Then, yarn joining with the yarn held by the clamp cutter 23 is performed, and a predetermined amount of yarn is fed into the trial knitting machine 16 to be in the state of FIG. Further, the synthetic fiber package P that was in the sampling station S2 moves to the surface layer yarn knotting station S3, and the knot 3
1 is formed. By repeating the above operation, the yarns necessary for the test knitting are sequentially produced from the large number of synthetic fiber packages P in the trial knitting machine 1.
Taken in 6.

By the way, when evaluating the quality of the test knitting, it can be easily evaluated in comparison with a cloth knitted with a standard yarn. Although it is possible to compare with another cloth, it is easy to compare if a standard is knitted during the trial knitting. Further, the boundary of trial knitting for each synthetic fiber package P can be distinguished by looking for a small protrusion of the seam of the yarn, but it is not easy to find the seam from a continuous cloth. Therefore, for example, if a cloth of colored threads is woven every 10 threads, it is easy to find the seam within the range of 10 pieces.

Therefore, the standard package S of FIG.
Switching between P and synthetic fiber package P, color package C
Switching between P and synthetic fiber package P, standard package SP
And the switching of the color package CP is performed at the sampling station S2.

FIG. 6 shows an example of a switching process from the synthetic fiber package P to the standard package SP. In FIG. 6A, the yarn of the synthetic fiber package P is the clamp cutter 23.
The yarn that is cut by and reaches the trial knitting machine 16 is held. The yarn end on the side of the synthetic fiber package P is sucked into the bobbin B by the suction pipe 17. Then, the clamp cutter 24 holding the standard package SP moves up as shown in the drawing to guide the standard yarn to the yarn joining device 15. Then, yarn joining with the yarn reaching the trial knitting machine 16 is performed.

Then, as shown in FIG. 6B, a predetermined amount of yarn from the standard package SP is taken into the trial knitting machine 16. The synthetic fiber package P in which the yarn necessary for the trial knitting is taken in is discharged as indicated by an arrow f. Next, FIG.
As shown in (c), the new synthetic fiber package P is fed in as shown by the arrow g, and the yarn end is introduced into the yarn joining device 15 in the manner described above. At the same time, the thread of the standard package SP is cut by the clamp cutter 24 and held. Then, the standard yarn reaching the trial knitting machine 16 and the yarn of the new synthetic fiber package P are spliced, and the yarn is taken in from the synthetic fiber package P.

The switching from the synthetic fiber package P to the color package CP and the switching between the standard package SP and the color package CP are similarly performed. Also,
The color packages CP can be switched for each synthetic fiber package.

In the case of tubular knitting, the boundary between the synthetic fiber packages P and the boundary between the standard package SP and the synthetic fiber package P are determined by the seams of the yarns. A method for clarifying this seam will be described with reference to FIG. In the figure, the tail 33 upstream of the seam 32 in the traveling direction is cut as short as possible, while the tail 34 downstream of the traveling direction hangs down for a long time. When weaving the yarn in this state, the seams in the stitches appear to swell as lines instead of dots,
Easy to identify.

A state example of the above-described test knitting will be described with reference to the development view of FIG. From the color 35 to the standard 36, the threads for 10 synthetic fiber packages are woven. With the presence of the collar 35, it is possible to easily count the number of defective portions by the number of divisions, and since the seams of the threads of each synthetic fiber package have long tails, the seams 37 of the stitches are also long and can be easily identified. . Then, if there is a defective portion in comparison with the standard 36, the number is counted and the defective package is specified. The peg tray 3 shown in FIG. 1 is provided with an ID such as a bar code, and when a defective package number is input, the defective package is automatically identified by the inspection station S4 and discharged to the bypass line 2. .

Further, a layout example of a drawing false twisting machine test factory including the above-mentioned synthetic fiber processing line will be described with reference to FIG. Reference numeral 50 is a yarn unpacking station, 51 is a draw false twisting machine, and 52 is a synthetic fiber conveying line. Then, the draw false twisting machine 51 includes a yarn feeding exchange device 53 and a package carrier 54.
