The peg tray 4 on which the synthetic fiber package P can be placed is conveyed on the conveyance line 1 in the direction of the arrow.

Along the transport direction of the transport line 1, a transfer device 11, a sampling device 12 in the first bypass line 2, an automatic warehouse (storage device) 13, an inspection device 14 in the second bypass line 3, and a bag. Packing device 15, box packing device 16
Are connected in series. On the opposite side of the sampling device 12 from the first bypass line 2, a tubular knitting device 18 is disposed with a work passage 17 interposed therebetween, and a main controller (control device) for controlling these devices in an appropriate place near the transport line 1. A tube knitting cloth inspection device 20 is provided at a location separate from the transport line 1.

In the transfer device 11, a circulation rail 24 for a ceiling transport device 23 for transporting the package carrier 22 from the draw false twisting machine 21 rides. The package carrier 22 has a total of 12
Pegs for projecting the packages are protruded, and nine package carriers 22 for nine spans corresponding to one machine run along the circulation rail 24 in a connected state. That is, the packages transferred to the tray 4 in order from the package carrier 22 are in the order from the first weight to the 108th weight of the specific machine. The transfer device 11 receives, for example, the synthetic fiber package P held by the carrier 11 on a peg shaft with a chuck (not shown), converts the horizontal attitude to the vertical attitude, and transfers the synthetic fiber package P to be inserted from above the peg tray 3. It is listed.

The sampling device 12 includes a yarn feeding station S1, a sampling station S2, and a surface yarn knotting station S3. A thread take-out sensor 25 for detecting a thread take-out is attached to the thread take-out station S1, and an I-
A first ID sensor 26 for reading a D number is attached. The first bypass line 2 is a line extending from the downstream side to the upstream side of the sampling device 12. The first line switching sensor 27 detects the tray 4 in which the yarn feeding failed, and detects the tray detected by the first tray switching device 27. 2, the tray is stopped by the stopper 28, and is temporarily stored. After the operator has modified the package so that the yarn can be picked up, the tray 4 is returned to the transport line 1 again.

As shown in FIG. 2, at the Itoyama station S1, a rotating device 112 for the peg tray 4, a suction mouse 113, and a soccer 11
4 are provided. The suction mouth 113 has an elongated opening 113a facing the side surface of the synthetic fiber package P and can be sucked in the direction of arrow a.
This is to suck the yarn end sticking to the surface layer of the synthetic fiber package that rotates slowly.

The soccer 114 is provided with a suction pipe 114b at the tip of a turning lever 114a. The turning lever 14a can be moved up and down as shown by an arrow b by a slide device (not shown), and is driven by an arrow c by driving means (not shown).

Further, as shown in FIG.
The main body 115a is located at the back of the yarn path, and at the time of splicing, levers (not shown) positioned above and below the main body 115a take in the yarn ends of the two yarns into the main body 115a by a turning operation and twist with an air nozzle. After the entanglement of the filaments is carried out and the yarn is spliced, an extra yarn end is cut by a cutter.

The tubular knitting device 18 arranged opposite to the sampling station S2 with the working passage 17 therebetween is provided with:
A feeder 127, a first tubular knitting machine 128, a second tubular knitting machine 129, and a sorting unit 131 are provided. Feeder 12
Reference numeral 7 denotes a drum for winding the yarn after the piecing, and a predetermined amount of yarn is drawn in and stored, and the cylindrical knitting machine 1 is passed through the sorting unit 131.
The yarn is continuously supplied to 28 and 129. Tube knitting machine 12
8, 129 is to knit one thread into a tubular shape,
Since it is necessary to change the size of the stitches depending on the thickness of the yarn, the first cylinder knitting machine 128 for the fine mesh and the second cylinder knitting machine 129 for the thick mesh are required.
And either is used. Predetermined tubular knitting machine 128,1
A sorting unit 131 is provided to sort the yarns 29. The sorting unit 131 is controlled by the main controller 19 that stores the source of the package and the quality information in association with each other. For example, the knitting machines 128 and 1 are provided for each quality or each base.
29 is automatically switched. Therefore, the tubular knitting device 18
It is not necessary to have a sensor that classifies each quality or each base. In addition, as shown in FIG. 1, since the tube knitting device 18 is disposed with the work passage 17 interposed therebetween, it is easy to add a tube knitting machine as indicated by a two-dot chain line. Further, since the operator can access the sampling device 12 or the tubular knitting device 18 only by changing the direction in the work passage 17, threading, maintenance of each device, removal of the tubular knitted fabric, and the like become easy.

Returning to FIG. 2, the clamp cutters 124, 1
25 is a standard package SP or a color package CP
Of the package, and holds the yarn on the package side.
Guide the thread to The clamp cutter 123 cuts the yarn from the synthetic fiber package P to the tubular knitting device 18 and holds the yarn on the tubular knitting device 18 side. Then, the yarn on the synthetic fiber package P side is pulled into the bobbin B by suction of the suction pipe 117.
Is sucked from the top of the bobbin, and the yarn end hangs down in the bobbin B. The surface yarn knotting station S3 is provided with a knotting device 130 that sucks and grips a yarn end in a bobbin and forms a knot around the package.

The operation of the above-described sampling device 12 and tube knitting device 18 is as follows. In FIG. 2, the synthetic fiber package P supplied to the yarn feeding station S1 is rotated together with the peg tray 4 by the rotating device 112, and the yarn end of the surface layer is sucked by the suction mouth 113. The sucked yarn ends are traversed by the rotation of the synthetic fiber package P. The yarn end traversed by the suction mouse 113 is sucked into the soccer 114. Then, when the soccer 114 rises as indicated by the arrow b, the yarn of the synthetic fiber package P is rapidly unwound, and there is a possibility that the yarn may be damaged at the time of doffing, or the yarn corresponding to the portion where oil is not applied passes through the soccer 114. Discarded in a dust box not shown.

The yarn of the synthetic fiber package P at the sampling station S2 is cut by the clamp cutter 123 after sampling, and the yarn reaching the tubular knitting device 18 is held. The yarn end on the synthetic fiber package P side is pulled by the suction pipe 117, sucked into the bobbin B, and hangs down.
Then, the synthetic fiber package P of the yarn feeding station S1 moves to the sampling station S2, and the soccer 11
The yarn reaching No. 4 is introduced into the yarn guide 120 and the yarn joining device 115. Then, piecing with the yarn held by the clamp cutter 123 is performed, and a predetermined amount of yarn is sent to the tubular knitting device 18. The synthetic fiber package P at the sampling station S2 is replaced with a surface yarn knotting station S3.
And the knot 131 is formed by the yarn knotting device 130. By repeating the above operation, many synthetic fiber packages P
The yarns necessary for the test knitting are taken into the tubular knitting device 18 in order from.

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, if a color yarn cloth is knitted every twelve pieces, it is easy to find a seam within a range determined to be twelve pieces. Switching between the standard package SP and the synthetic package P, switching between the color package CP and the synthetic package P, and switching between the standard package SP and the color package CP are performed at the sampling station S2.

From synthetic fiber package P to standard package SP
The following is an example of the switching process to the mode. The yarn of the synthetic fiber package P is cut by the clamp cutter 123, and the yarn reaching the tubular knitting device 18 is held. The yarn end on the synthetic fiber package P side is sucked into the bobbin B by the suction pipe 117. And a clamp cutter 1 for holding the standard package SP.
24 rises and guides the standard yarn to the yarn joining device 115. Then, piecing with the yarn reaching the tubular knitting device 18 is performed. Then, a predetermined amount of the yarn from the standard package SP is taken into the tubular knitting device 18. Next, a new synthetic fiber package P is sent in, and the yarn ends are joined to the yarn joining device 115 in the manner described above.
Will be introduced. At the same time, the yarn of the standard package SP is cut by the clamp cutter 124 and held. Then, the standard yarn reaching the tubular knitting device 18 and the yarn of the new synthetic fiber package P are spliced, and the yarn is taken in from the synthetic fiber package P. Switching from synthetic fiber package P to color package CP, standard package SP
Switching between and the color package CP is performed in a similar manner. Also, color package CP and standard package SP
Is optional and may not be used.

An example of the state of the test knitting described above will be described with reference to a developed view of FIG. 108 from color 135 to standard 136
Yarn for each synthetic fiber package is woven. Color 1
With the presence of 35, it is possible to easily count the order of the defective part by the amount of the eye and easily identify the defective package. If there is a defective part in comparison with the standard 136, the number is counted and the number of the defective package is specified.

FIG. 5 shows an automatic warehouse (storage device) 1 suitable for storing the entire tray in which the synthetic fiber package P is inserted.
3 is shown. A first row of shelves 152 and a second row of shelves 153 are provided on both sides of a bogie 151 that can reciprocate along the center line.
The first lifter 154 is connected to one end of the shelf row 152,
A second lifter 155 is connected to one end of the shelf row 153. The illustrated position of the cart 151 is the home position, and as shown in the figure, 3 × 2 rows of trays can be stored in, for example, 12 upper and lower tiers. Transport line 1
When six trays are placed on the first lifter 154 from the loading side of the trolley 151, the six trays are moved up and stored in predetermined shelves of the cart 151. The cart 151 is, for example, the first shelf row 152.
The trays are pushed out and stored simultaneously, facing the shelves Nos. 1 and 2. By repeating the above operation, the packages are stored in the sampling order of the sampling device 12. To take out the package, the cart 151 receives the trays, for example, facing the shelves No. 1 and No. 2 in the first shelf row 152, returns to the home position shown in the drawing, and sequentially puts the second lifter in the order from the one placed first. It is discharged to the unloading side of the transport line 1 via 155.

As described above, the automatic warehouse 13 can be discharged in the order in which it is inserted, so that the order of the packages is not changed. Further, since the entire tray is stored, it is not necessary to insert and remove the package from the tray. Further, since the shelf structure is used to regularly store a large number of trays, the installation space for the automatic warehouse 13 is reduced. The storage amount of the automatic device 13 is equal to or more than 7 hours for the group of the draw false twisting machine 21. During that time, the dyeing inspection of the tubular knitted fabric by the tubular knitting device 18 is performed so that a defective package can be identified. It has become.

Returning to FIG. 1, a second ID sensor 29 is attached to the transfer line 1 on the discharge side of the automatic warehouse 13 and recognizes a tray identified as a defective package by the tubular knitting cloth testing apparatus 20, and checks the tray. The second tray switching device 30 is operated by passing through the bagging device 15 and the bag filling device 15, and is temporarily stored by the stopper 31 of the second bypass line 3. The inspection device 14 is mainly for inspecting the external appearance of the package.
An ID sensor 32 is attached. Bagging device 15
Wraps a good product package with a thin plastic film. The box packing device 16 is for removing the package packed from the tray and packing it in a shipping box. Therefore, the empty tray is discharged from the box packing device 16 and the boxed product is shipped.

Next, control of the above-described package inspection system will be described. In FIG. 1, a main controller (control device) 19 is provided at an appropriate position near the transport line 1, and an input device 41 (input means) and a storage device (storage means) are provided.
42 are connected. In order to control the system, the tray 4 is provided with an ID number (tray information) such as a bar code, and the ID sensors 26, 29, 32.
Can read the ID number of the tray 4 and recognize the package of the specific ID number. The tray information is not limited to a barcode, but may be a piece of information on which a readable and writable recording medium such as a magnetic tape is attached.

As shown in FIG. 6, a main controller (control device) 19 to which an input device (input means) 41 and a storage device 42 are connected includes a draw false twisting machine 21, a ceiling transport device 23, a transfer device. 11, sampling device 12, tube knitting device 18, automatic warehouse 13, inspection device 15, and packing device 1
6 and the controller of each device, the thread take-out sensor 25, the first ID sensor 26, the second ID sensor 29, and the second I
Sensors such as the D sensor 32 and transport line control devices such as the stoppers 28 and 31 and the tray switching devices 27 and 30 are connected. The tubular knitted fabric from the tubular knitting device 18 is carried by the operator to the tubular knitted fabric inspection device 20, and, for example, a test result by dyeing is input from the input device 41 to the main controller 19 by the operator. Therefore, the input device 41 forms an input unit.

The main controller 19 is provided with the draw false twister 2
1. By controlling the ceiling transfer device 23 and the transfer device 11, the packages from the first weight to, for example, 108 weights are sequentially transferred to the tray 4 in the order of the determined machine base, and the transfer line 1
Control to send to. Then, the package that has been conveyed to the yarn unwinding station S1 in FIG. 1 and has failed in yarn unwinding is temporarily stored in the bypass line 2. For this reason, the order of the weights jumps, but since the operator assists in threading and returns to the sampling device 12 for each machine, the weight remains in a group for each machine.

First ID of sampling station S2
Sensor 26 is used to detect the I
Read the D number and, as shown in FIG.
The machine numbers (N, N + 1,...) And the weight numbers (1, 2, 3,...) Correspond to the D numbers (R1, R2,.
107, 108, 15, 39) in the storage device 42 in the storage table. Here, the weight numbers 15 and 39 indicate that the yarn feeding failed, and this number can be recognized by the yarn feeding sensor 25 of the yarn feeding station S1. All that is required is to return to the sampling device 12 in the order in which the operator failed. At this time, the main controller 19 controls the sampling device 12 and the tubular knitting device 18 to automatically produce the tubular knitted fabric. However, the operator removes the tubular knitted fabric. In order to perform such an operator's work quickly, a work passage 17 shown in FIG. 1 is provided. When a magnetic tape is used as the tray information, the machine number, the weight number, and the like are directly read and written in the sampling order.

Then, the main controller 19 controls the automatic warehouse 13 to store the packages in the sampling order, and after a lapse of a predetermined time until the result of the tubular knitting cloth inspection device 20 is inputted, the main controller 19 executes the sampling in the sampling order. Make sure the package is issued. Since the sampling order is determined, the operator can specify the order of the defective package in the specific machine using the tubular knitted cloth as shown in FIG. The result is input to the main controller 19 by using the input device 41, and writing indicating that the package is defective is performed as sampling information corresponding to the specific ID number as shown in FIG. Is stored in the storage device 42 in an appropriate state. That is, the controller 19 constitutes not only the control devices of various devices, but also a writing means for writing the inputted inspection result in the storage table of the storage device 42 in association with the tray information (ID number).

Therefore, at the stage when the package is discharged from the automatic warehouse 13, the defective package can be specified by the test knitting. The tray specified by the second ID sensor 29 of FIG. 1 passes through the inspection device 14 and the bag filling device 15 under the control of the main controller 19, and operates the third tray switching device 30 to move the tray to the second bypass line 3. Can be put in.

The ID number of the tray of the defective package newly found by the inspection device 14 is the third ID sensor 3
2 and written as inspection information as shown in FIG. 7, and the written result is stored in the storage device 42 in the state shown in the figure. The main controller 19 also controls the defective package by operating the third tray switching device 30 to enter the second bypass line 3.

FIG. 8 is a diagram showing another package inspection system. The difference from the one shown in FIG. 1 is that the automatic warehouse is, for example, a rotating conveyor in which a large number of horizontal pegs are arranged in a vertical direction, and a type in which packages are hung on the pegs and stored. Therefore, the transport line 1 is an automatic warehouse 5
1 to the first transport line 52 and the second transport line 5
The trays can be circulated through tray collection and tray supply. In this case, the tray changes between the entrance side and the exit side of the automatic warehouse 51,
The automatic warehouse 51 adheres to the rule that the automatic warehouse 51 enters and exits in the sampling order, and as long as the number of stocks is known, the ID number of the new tray is read by the ID sensor 54 on the discharge side of the automatic warehouse 51 and the old ID number is read. Can be replaced with

[0038]

As described above, according to the first aspect of the present invention, the identification of a defective package by an off-line inspection after sampling can be performed at the stage of being discharged from the storage device. Therefore, there is an effect that processing such as removal of a defective package is reliably and automatically performed. Therefore, there is no need to take out a defective package after packing in a box. In other words, offline inspections such as dyeing tests
Inspection can be recognized as a defective package.
Inspection device to inspect the appearance of the package,
Only the package can be wrapped.

According to the second aspect of the present invention, since the storage device is an automatic warehouse that receives and discharges packages in the order of sampling, the arrangement of the packages is efficient, so that many packages can be stored in a small storage device. This has the effect of reducing the installation space for the device.

According to the third aspect of the present invention, it is possible to specify the machine base on which the defective package has occurred and the weight thereof, and it is possible to reliably and promptly pursue the cause of the occurrence of the defective package and take countermeasures.
