DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package transport system for performing inspection while transporting a synthetic fiber package or the like processed by a draw false twisting machine or the like.

[0002]

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

[0003] The synthetic fiber package transferred to the pin track in this way is transported to a predetermined place and then shipped through an inspection step and a packing step.

[0004] Incidentally, the degree of processing of the synthetic fiber package after the stretching false twisting machine is not always uniform, and the 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 the untwisted portion often appears at a fixed period, and when it is made into a cloth, the existence and the degree of the untwisted portion can be clearly seen at a glance.

[0005] Therefore, a certain amount of yarn is collected from each synthetic fiber package, and the yarn is successively spliced into a continuous yarn, which is tested and knitted by a tubular knitting machine, and this test knitted fabric has many untwisted portions. The presence or absence of a defective package is checked.

[0006]

However, the collection 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 transported together with the pin track to the trial knitting machine, and a predetermined amount (about 50 m) of the yarn of the individual synthetic fiber package hung on the pin is manually fed into the feeder of the trial knitting machine, and the cut yarn end is cut. The manual work of splicing to the next synthetic fiber package was performed. For this reason, there was a problem that it took eight hours for four people to complete the collection and trial knitting of the yarn from the synthetic fiber package for one lot in a normal factory. In addition, the trial knitted fabric is made by continuously knitting yarns from each synthetic fiber package, and since the distinction between each synthetic fiber package is unclear, color yarns may be inserted between them. The splicing was also done manually. Further, when comparing a trial knitted fabric with a standard fabric, a standard yarn is knitted into various places of the trial knitted fabric for comparison, but the splicing with a standard package has also been performed manually.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object the collection and trial knitting of yarn from a number of packages, as well as standard packages or An object of the present invention is to provide a package transport system in which switching with a color package is performed continuously and automatically.

[0008]

In order to solve the above-mentioned problems, a package transport system is provided with a sampling station on a transport line through which packages are sequentially transported, for pulling out yarn from each package and sequentially splicing the yarns. A trial knitting machine is connected, and a standard package wound with a standard yarn for comparison and / or a color package wound with a color yarn for discrimination is set to be switchable to the sampling station.

[0009]

In the transport line, the inspection of the appearance, twill drop, fluff, etc. is performed while being transported by the conveyor while being placed on the peg tray. A sampling station is provided on this transport line to pull out yarns from each package and splicing them sequentially, and when a trial knitting machine is connected to this sampling station, a predetermined amount of yarn is collected automatically, and after the splicing, The trial knitting by the trial knitting machine is automatically performed. Because the standard package and / or color package are switchably installed at this sampling station,
During the trial knitting of the package, a standard cloth for comparison or a colored cloth for differentiation can be automatically knitted.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a device layout diagram of the package transport system of the present invention, FIG. 2 is a front view of a main part of the package transport system, and FIG. 3 is a side view of a main part of the package transport system.

In FIG. 1, reference numeral 1 denotes a rectangular, circulable transport line, and reference numeral 2 denotes a bypass line. The conveyor line 1 and the bypass line 2 are connected to a conveyor, and a peg tray 3 on which a synthetic fiber package can be placed is conveyed thereon in the direction of the arrow. Then, the peg tray 3 is moved by the protrudable stoppers 4 and 5 on the conveyor.
Can be stopped at a predetermined location.

Along the transport direction of the transport line 1, a transfer station S0, a surface yarn unwinding station S1, a sampling station S2, a surface yarn knotting station S3, an inspection station S4, and a packing station S5 are arranged in this order. . The bypass line 2 is a line extending from the downstream to the upstream of the inspection station S4. The defective synthetic package detected at the inspection station S4 is temporarily stored in the bypass line 2, and the modified synthetic package is re-transferred to the transport line. It can be returned to 1.

The transfer station S0 is provided with a transfer device 10, which receives the synthetic fiber package P held by the carrier 11 of the overhead carrier on a peg shaft with a chuck (not shown), converts the horizontal position into a vertical position, and converts the vertical position into a peg tray. 3, the synthetic fiber package P is transferred so as to be inserted from above.

As shown in FIG. 2, at the surface yarn unwinding station S1, a rotating device 12 for the peg tray 3, a suction mouse 13, and a soccer 14
Are provided. The suction mouth 13 has an elongated opening 13a toward the side surface of the synthetic fiber package P and can be sucked in the direction of the arrow a. The suction device 13 sucks the yarn end stuck to the surface layer of the synthetic fiber package that rotates slowly by the rotating device 12. Things.

The soccer 14 is provided with a suction pipe 14b at the tip of a turning lever 14a.
Reference numeral a denotes a sliding device (not shown) which can be moved up and down as shown by an arrow b, and can be turned by a driving means (not shown) as shown by an arrow c. The soccer 14 at the solid line position has a suction pipe 14 near the upper end of the opening 13a of the suction mouse 13.
When the yarn sucked by the suction mouth 13 and unwound while traversing is traversed up to the upper side of the synthetic fiber package P, the yarn in the suction mouth 13 is sucked and transferred to the suction pipe 14b. Let Therefore,
The suction force of the soccer 14 is set to be larger than the suction force of the suction mouse 13. Then, when the soccer 14 rises as indicated by the arrow b, the unwinding direction of the yarn becomes the axial direction of the synthetic fiber package P, and the yarn is rapidly unwound regardless of the rotation of the synthetic fiber package P, and a considerable amount of yarn is sucked. It is carried to a dust box not shown. In addition, soccer 14
Is turned as shown by the arrow c to the position indicated by the two-dot chain line, the yarn can be introduced into the yarn guide 20 and the yarn joining device 15 described below.

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

Further, as shown in FIG.
5 is located at the back of the yarn path, and at the time of splicing, levers (not shown) located above and below the main body 15a take in the yarn ends of the two yarns into the main body 15a by a pivoting operation.
After twisting with an air nozzle to form entanglement between filaments and splicing, the excess yarn end is 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 splicing, draws and stores a predetermined amount of the yarn, and continuously supplies the yarn to the tubular knitting devices 28 and 29. The tubular knitting devices 28 and 29 are for knitting one yarn into a tubular shape, and it is necessary to change the size of the stitch according to the thickness of the yarn. Any of the tubular knitting devices 29 is used.

Returning to FIG. 2, the clamp cutters 24, 25
Cuts the yarn from the standard package SP or the color package CP and holds 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 synthetic fiber package P side is sucked from the top of the bobbin B by the suction of the suction pipe 17, and the yarn end hangs down in the bobbin B.

The surface yarn knotting station S3 is provided with a knotting device 30 that sucks and grips the yarn end in the bobbin and forms a knot on the outer periphery of the package.

Next, the operation of the essential parts of the above-described package transport system will be described with reference to FIGS. 4 and 5 show a yarn joining process between the synthetic fiber packages P. FIG.
In (a), a new synthetic fiber package P is supplied to the unwinding station S1, and the sampling station S2
In the example, the synthetic fiber package P is drawn 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 ends are traversed by the rotation of the synthetic fiber package P.

In FIG. 4B, the suction mouse 1
The yarn end to be traversed in 3 is sucked into the soccer 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 discarded in a dust box (not shown). The reason why a considerable amount of yarn is discarded is as follows. When doffing is performed by the automatic doffer, the end of the yarn may be damaged because the doffing device touches the yarn. Trial knitting of damaged yarn ends may not accurately evaluate the quality. In a draw false twisting machine, oil is usually applied to a yarn before winding by an oiling device. But,
When doffing with an automatic doffer, the yarn being wound is cut, and doffing is performed while sucking the yarn end. Cutting and suctioning are performed afterwards. Therefore, since the yarn end is a non-oiled yarn, the quality may not be accurately evaluated by trial knitting. Therefore, until there is no part that could be damaged by doffing and the oiled regular yarn, soccer 1
4 sucks.

Further, 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 synthetic fiber package P side is pulled by the suction pipe 17, sucked into the bobbin B, and hangs 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, the splicing with the yarn held by the clamp cutter 23 is performed, and a predetermined amount of the yarn is sent to the trial knitting machine 16, as shown in FIG. The synthetic fiber package P at the sampling station S2 moves to the surface yarn knotting station S3, and the knot 3
1 is formed. By repeating the above operation, the yarn necessary for the test knitting is sequentially formed from the many synthetic fiber packages P in the trial knitting machine 1.
It is taken into 6.

Incidentally, when evaluating the quality of the test knitting, it can be easily evaluated in comparison with a cloth knitted with a standard yarn. Other fabrics can be compared, but it is easier to compare by knitting the standard during trial knitting. Further, the boundary of the trial knitting for each synthetic fiber package P can be distinguished by searching for small projections of the seam of the yarn, but it is not easy to search for the seam from a continuous cloth. Therefore, for example, when a color yarn cloth is knitted every ten pieces, it is easy to find a seam within a range determined to be ten pieces.

Therefore, the standard package S shown in FIG.
Switching between P and synthetic fiber package P, color package C
Switching between P and synthetic fiber package P, standard package SP
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 package P to the standard package SP. In FIG. 6A, the yarn of the synthetic fiber package P is a clamp cutter 23.
, And the yarn reaching the trial knitting machine 16 is held. The yarn end on the synthetic fiber package P side is sucked into the bobbin B by the suction pipe 17. Then, the clamp cutter 24 holding the standard package SP rises as shown to guide the standard yarn to the yarn joining device 15. Then, piecing with the yarn reaching the trial knitting machine 16 is performed.

Then, as shown in FIG. 6B, a predetermined amount of the yarn from the standard package SP is taken into the trial knitting machine 16. In addition, the synthetic fiber package P into which the yarn necessary for the trial knitting is taken in is discharged as shown by an arrow f. Next, FIG.
As shown in (c), a new synthetic fiber package P is fed in as indicated by an arrow g, and the yarn ends are introduced into the yarn joining device 15 in the manner described above. At the same time, the yarn 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 performed in the same manner. Also,
Switching of the color package CP can also be performed for each synthetic fiber package.

By the way, in the case of tubular knitting, the boundary between the synthetic packages P and the boundary between the standard package SP and the synthetic package P are determined by the seam of the yarn. A method for clarifying the seam will be described with reference to FIG. In the figure, the tail 33 upstream of the seam 32 in the running direction is cut as short as possible, while the tail 34 downstream in the running direction hangs long. When knitting the yarn in this state, the seam in the stitch looks swollen as a line instead of a point,
Easy to identify.

An example of the state of the test knitting described above will be described with reference to a developed view of FIG. From the color 35 to the standard 36, yarns for ten synthetic fiber packages are woven. The presence of the collar 35 makes it possible to easily count the number of the defective part by a measure. The seam of the yarn of each synthetic fiber package has a long tail, so that the seam 37 of the stitch is long and can be easily identified. . If there is a defective portion in comparison with the standard 36, the number is counted and the defective package is specified. Note that an ID such as a barcode is attached to the peg tray 3 in FIG. 1. When the number of a defective package 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 plant including the above-described synthetic fiber processing line will be described with reference to FIG. 50 is a yarn feeding unpacking station, 51 is a draw false twisting machine, and 52 is a synthetic fiber transport line. The drawing false twisting machine 51 includes a yarn feeder exchange device 53 and a package carrier 54.
Are arranged. And the yarn feeding unpacking station 50
And a station 54a at the end of the package carrier 54.
The station 53a beside the home position of the yarn feeder 53 and the transfer station S0 of the synthetic fiber processing line 52 are connected by a ceiling rail 55, and the two ceiling transport vehicles 5
6 and 57 can run on the ceiling rail 55 freely. The ceiling transport vehicle 56 transports the synthetic fiber package ascended from the drawing false twisting machine 51 to the synthetic fiber transport line. The overhead transport vehicle 57 feeds the yarn supply package P ′ to the yarn supply exchange device 53 for the draw false twister 51.
To supply. According to the above-described layout, the inspection by trial knitting is performed before the synthetic fiber package from the drawing false twisting machine is automatically inspected and packed on the synthetic fiber conveying line.
