Abstract

PROBLEM TO BE SOLVED: To improve the precision in the judgment in a line by grading yarn by using not only the data on weight and visual inspection for a wound bundle but also the quality data of the yarn to be worked into the wound bundle. SOLUTION: A target value TO of yarn tension, a target scope with suitable upper and lower margins, and an allowance scope with upper and lower margins of a limit which is allowed from the target value TO are input in a tensile force control part in advance to adjust contact pressure of a false twister so that untwisting tensile force T is in this target scope (Tu<T<Td). If abnormal untwisting tensile force T which exceeds the allowance scope is detected during this control (T>Tmax, T<Tmin), the tensile force value and a period of the detection (yarn length L1) are input into a winding control part of a winding control mechanism every time the abnormality is detected. Moreover, even when the untwisting tensile force T exceeds the target scope, the tensile force value and a period of the detection (yarn length M1) are detected. The yarn is graded for the quality of draw false-twist working based on the target scope and a degree which exceeds the allowance scope.

Labeler 17 is a sealing device for wrapping with a plastic film.

The yarn supply package P1 unpacked by the depalletizing device 18 is supplied to the draw false twisting machine 1 via the creel 19 via the overhead conveyor 3 and the creel robot 2. The draw false twisting machine 1 unwinds the yarn supply package P1 once, applies draw false twisting to the yarn, and rewinds the yarn into the package P2. The drawing false twisting machine 1 includes a plurality of weights each including a single-weight independent type automatic doffing device and a tension sensor 35 described later, and recognizes yarn quality data such as yarn tension for each package. Package P2 that has been stored and filled
Is discharged to a storage arm provided on each weight, and is temporarily stored. Each weight of the drawing false twisting machine 1 performs a constant length winding at the same yarn speed, and the full package P2 is discharged from each weight and stored in the storage arm every time corresponding to the constant length. .

A package shutter for simultaneously opening the storage arms of the respective weights of the drawing false twisting machine 1 and simultaneously ejecting only the package at the tip thereof is provided. This package shutter has a time slightly shorter than the time corresponding to the fixed length. It operates all at once. By operating the package shutter slightly shorter than the time corresponding to the fixed length, not only full balls but also half balls can be automatically transported. By simultaneously discharging the package from each weight along the outside of the machine, the STS carrier 4
The packages are placed in the order of weights along the machine base.
Therefore, the package P2 discharged from the drawing false twisting machine 1 in accordance with the order of the weights is transported by the STS transport vehicle 4 to the tray transfer device 6 of the tray circulation device 20, and is transferred to the tray. Thus, it is possible to associate the source that has gone up to the weight of the drawing false twisting machine 1.

In the tray circulating device 20, a weight inspection (the weight inspection device 7), a knitting inspection (the sampling device 8 and the knitting inspection device 9) of the package P2 placed on the tray,
Then, an appearance inspection (appearance inspection device 12) is performed. Data (inspection data) for each roll from these inspection means
The data is sent to the host computer 73 (see FIG. 1), and is graded as “A”, “B”, “C”, etc., together with data (quality data) on the quality of the yarn from the draw false twister 1 described later. These ratings are written in the ID number of the tray on which each package is placed. Thereafter, the package is stored in the automatic warehouse 10 in a state where the storage location is associated with the rating such as “A”, “B”, or “C”. The package tray ID numbers in the automated warehouse 10 include:
The result of the knitting inspection is also written by the crowd, and the automatic warehouse 1
The quality of the package within 0 is determined. Then, a package of a predetermined quality is taken out from the automatic warehouse 10 and carried out through the bagging device 14, the packing device 15, the labeler 16 and the sealing device 17.

In FIG. 5, the drawing false twisting machine 1 includes feed rollers 24, 28, 30, heaters 25, 29, a cooling plate 26, and a belt type false twisting device 27.
The synthetic yarn Y pulled out from the yarn supply package P1 by the first feed roller 24 is introduced into the primary heater 25, reaches the second feed roller 28 via the cooling plate 26 and the belt type false twist device 27, and further reaches the secondary feed roller 28. Heater 2
9. Winding package P2 via third feed roller 30
Is formed. The twist formed by the belt type false twist device 27 propagates to the first feed roller 24 and is thermally fixed by the primary heater 25. That is, the belt type false twist device 27
Is the twisting side, and the downstream side is the untwisting side. In a draw false twisting machine, such a unit is regarded as one weight,
A large number of the weights are arranged in the thickness direction of the paper.

The belt type false twisting device 27 is composed of two belts 33 and 34 provided so as to cross each other.
Is detected by a tension sensor 35 provided on the downstream side of the belt-type false twisting device 27. The tension sensor 35 measures the untwisting tension, and adjusts the nip force of the belt type false twisting device 27 by controlling the contact pressure between the two belts so that the untwisting tension falls within a predetermined control range. ing. Further, a yarn break sensor 36 is provided downstream of the secondary heater 29. Reference numeral 37 denotes a yarn cutter, which cuts the yarn upstream of the first feed roller 24 in conjunction with the detection of the yarn breakage sensor 36, and prevents the occurrence of yarn entanglement in the middle of the path.

The drawing false twisting machine 1 is provided with an automatic doffing device independent of a single weight. That is, doffing work such as replacement of a paper tube used in a false twisting machine and thread hooking is automatically performed for each spindle. Then, the fully loaded winding package P2 is once held in the storage arm 38, and is simultaneously transferred to the carrier 40 constituting the transport vehicle of the STS 4 by opening and closing the package shutter 39, and the tray transfer device 6 shown in FIG.
Transported to Note that the tension sensor 35
The yarn in which the abnormal tension is detected is cut in the middle of the winding process, and is discharged as a half ball. Also, when a yarn break occurs due to a mechanical trouble, the yarn is discharged as a half ball. When the winding is interrupted in this way, the machine-equipped controller 70 shown in FIG. 1 refers to the value of the doffing timer 50, and determines that the time shorter than the specified value, that is, the yarn length of the half ball is equal to the predetermined length of 1 If the size of the small ball is / 10 or less, a lamp or the like is turned on to notify the worker and prompt the removal of the package. Also, if there is a package that has been manually removed,
When the packages are taken out from the respective weights in turn, empty space is created in the order. Therefore, the controller 70 automatically marks the quality data of the removed package based on the value of the doffing timer 50 to clarify that the data does not include the package. The weight and the weight are easy to associate with each other, and the quality data based on the yarn tension and the inspection data such as the appearance are compared with each other, so that there is no mistake in the rating.

Next, the tension control mechanism 41 and the winding management mechanism 42 will be described with reference to FIGS. These are to maintain the yarn tension satisfactorily based on the quality data from the tension sensor 35. When the yarn tension exceeds the allowable range, the yarn winding is stopped, and the yarn is discharged from the false twisting machine as a half ball. I do. In the present invention, in addition to such an operation, the quality data is stored in the host computer 73 (see FIG. 1), and is used for rating the package P2 that has been filled.

The tension control mechanism 41 includes a belt type false twist device 2
7, a tension sensor 35 provided on the downstream side of the yarn running direction
And a tension control unit 46 that drives the contact pressure control unit 45 of the belt type false twisting device 27 based on the detection value of the tension sensor 35.

As shown in FIG. 8, the tension controller 46 accepts a target value T0 of the yarn tension, a target range having an appropriate width (for example, ± 2 gr) above and below the target value, and a target value T0. The allowable range of the upper and lower limits (for example, ± 10 gr) of the limit is input in advance, and the untwisting tension T is set to the target range (Tu <
The contact pressure of the false twisting device 27 is adjusted via the contact pressure control means 45 so that T <Td). If an abnormal untwisting tension T out of the allowable range is detected during this control (T> Tmax, T <Tmin), the tension value and
The detection period (yarn length L) is input to the winding control unit 47 of the winding management mechanism 42 each time. Also,
Even if the target range (Tu <T <Td) is exceeded, the tension value and the detection period (yarn length M) are detected. With the degree exceeding the target range and the allowable range, the yarn can be graded according to the quality of the draw false twisting.

The winding control unit 47 of the winding management mechanism 42 is incorporated in a controller 70 provided on the base of the false twisting machine together with the tension control unit 46 to control the winder 49 of the false twisting machine and to control each weight. The winding package P which is full by the fixed length signal of the doffing timer 50 provided in the
2 is fried. Then, based on the information from the tension control unit 46, the quality of the package P2 being wound is determined, and if abnormal, the winding is not further performed.
The fried chicken is made to go immediately. That is,
In addition to the abnormal tension value as input information and the abnormal detection period L (L1 + L2 +...), Which is the accumulated value of the yarn length, the number of times (frequency) of abnormal tension detection N is counted, and these are set in advance. Compared to the acceptance rules (pass criteria), for example,
If the yarn length L of abnormal tension is 10 m or less, "a" grade product,
If L is 10 m or more, each winder 4 is determined to be “b” quality and at the time of determination of “b” quality.
An operation command is issued to the drive unit 53 of the automatic doffer 52 provided in the printer 9 and the discharge is performed as a half ball. Such an abnormal package is manually removed.

According to the present invention, further grading can be performed among the automatically transported "a" sized products. That is, among the "a" grades having the abnormal tension thread length L of 10 m or less, the "a1" grade having the abnormal tension thread length L of 5 m or less, and "a2" having the length of 5 m or more and 10 m or less. It can be rated like a genuine product. Further, it is also possible to classify the "a1" grade or "a2" grade by combining the thread length M and the thread length L when exceeding the target range (Tu <T <Td). The untwisting tension of the draw false twisting machine is related to the quality of the draw false twisting process, and the untwisting tension ranks the quality of the package yarn. As described later, the overall “A”, “B” and This can be used for determining “C”.

The automatic doffing device 52 includes a yarn cutting means 54 for cutting the processing yarn Y to be wound, and a cradle 55 for moving the cradle 55 for gripping the winding package P2 forward and backward and opening and closing appropriately. Drive shaft 5
6, a paper tube supply drive shaft 59 for raising and lowering a paper tube stocker 58 for accommodating an empty paper tube 57, and a threading arm 60 for threading a new paper tube 57. The thread cutting means 54 is provided near the traverse device 61 of the winder 49, and has a cutter 64 having a thread catching groove 63 provided with a blade 62, as shown in FIG.
And an actuator (not shown) for lifting the cutter 64 to the level of the yarn path. Then, in accordance with a command from the winding control unit 47, the actuator lifts the cutter 64, and the processing yarn Y during the traverse is moved.
To be caught and cut. The cut processed yarn Y is held by the air sucker 65 provided at the front end of the traverse device 61, and after the paper tube is replaced, is pulled to the end of the paper tube by the rotation of the yarn hook arm 60 and is hooked. . After the thread is cut, the cradle 55 is tilted backward by the rotation of the cradle drive shaft 56, and the cradle 55 is opened, so that the cradle 55 is wound around a receiving portion (not shown) provided at the rear of the winder 49. The package P2 is discharged. Subsequently, when the paper tube stocker 58 is lowered and the cradle 55 grips a new paper tube, the cradle 55 is tilted forward by the cradle drive shaft 56 until it comes into contact with the friction roller 66, and a new winding starts. Will be done.

Reference numeral 36 denotes a thread breakage detection sensor, which also doffs when a thread break occurs due to a mechanical trouble. The doffed package is temporarily held by a storage arm 38 provided on each weight. Then, based on a command output from the controller 70 with the machine every time shorter than the full winding long period T, the package shutter 39 discharges the leading package from the weight along the machine at the same time. I have.

Next, a block diagram of a system for discriminating a wound ball in the above-described wound ball manufacturing and conveying line will be described with reference to FIG. In FIG. 1, the main devices described in FIG. 4 are a creel robot 2, a draw false twisting machine 1, an STS 4, a transfer device 6 to a tray, a package weighing scale 7, a knitting inspection 9, a package appearance inspection 9, an automatic device. 10 and a labeler 13 are arranged in this order. The packages discharged from the drawing false twisting machine 1 are arranged in the order of the weight, and the automatic warehouse 1 is arranged in that order.
Transported to zero. Data relating to the quality of the yarn of the drawing false twisting machine 1 is input to the controller 70 with a machine base, and data relating to the packages of the package weighing scale 7 and the package appearance inspection 12 are input to the on-site personal computer 71. STS
4. The transfer device 6 to the tray 6 and the automatic device 10 enable the transfer by the transfer controller 75 in correspondence with the tray ID number and the source of the package. The labeler personal computer 74 for the labeler 13 is for outputting data necessary for the label. The machine-equipped controller 70, on-site personal computer 71, labeler personal computer 74, and transport controller 75 are connected to a host computer 73 via a main communication network 72. The host computer 73 determines the quality of each roll by combining the data for each roll from the yarn quality monitoring means such as the tension sensor 35 and the data for each roll from the inspection means such as the package appearance inspection 9. It functions as quality judgment means.

At the end of each machine of the drawing false twisting machine 1, there is provided a machine-equipped controller 70 equipped with a display of data or conditions necessary for operation, a temperature control device, various alarm devices, and a machine operation panel. I have. This machine-equipped controller 7
0 processes the data related to the quality of the yarn from the tension sensor 35 of the draw false twister 1 and controls the tension of the yarn, while controlling the source of the package (information such as which weight and what time it was formed). ) Can be recognized, and the quality data is input to the host computer 73 via the main communication network 72.

The on-site personal computer 71 has data on the weight of the package from the package weighing scale 7, data on the degree of dyeing from the knitting inspection device 9,
Inspection data such as data on the appearance of the package from the appearance inspection device 12 is input. These data are displayed on the on-site personal computer 71 and can be output on the spot (monitor or printout). Further, the sheet is discharged by the transfer controller 75 outside the drawing false twisting machine 1 and transferred while being compared with a tray ID number when the sheet is placed on a tray.
Each inspection data from the personal computer with site 71 is transmitted to the host computer 73 via the main communication network 72 in association with the number.
To enter.

As described above, the host controller 73 receives the yarn quality data from the on-board controller 70 and the inspection data on the packages from the on-site personal computer 71, and receives the appropriate data from a monitor or a printer. Output is possible by means. Therefore, for example, the data can be output by the host computer 73 as a data list as shown in FIG. And
For each package placed on the tray, the thread type, doff date and time, unit No., weight No., and ratings such as "A", "B", and "C" can be identified. Also, the host controller 73
Stores the individual data of the packages stored in the automatic warehouse 10, and can operate the warehouse crane 11 to retrieve the packages of the required rank.

The ID No. shown in FIG. As in the case of 144─48, data relating to small balls having a weight of 1/10 or less from the draw false twisting machine 1 due to abnormal tension or the like and marked as data for which no package is present are marked. However, the yarn quality data itself is sent to the host controller 73 as data for production management, like other data. Therefore, confusion of the packages when the quality results based on the yarn tension are added together after the appearance inspection is avoided.

The rating is as shown in FIG.
It is sequentially determined whether or not each data is within the category, and the data is sorted into “A”, “B”, and “C”. Step ♯
At 81, based on the quality data from the tension sensor 35, whether or not the tension is within the range, that is,
It is determined whether or not the above applies to the “a1” quality product. If the product is “a1” quality, the determination is made in step # 82 as to whether the weight is within the rating, and in step # 83 and step # 84, the determination as to whether the appearance is within the rating is added. A "or" B "is determined. On the other hand, if the quality data of the yarn is not within the range and the product is “a2” quality, the weight is determined at step # 85 at step # 8.
6. At step # 87, the judgment of "B" or "C" is made taking into account the judgment of the appearance.

The transport controller 75, based on commands from the host computer 73, the on-site personal computer 71, etc., executes the STS 4, the tray transfer device 6, and the automatic warehouse 10
The control of the transport line including the above is performed. In these transport lines, the transport controller 75 controls the I
DNo. And the quality and weight of the package on which transport line can be output from the host computer 73 as necessary.

In the above description of the embodiment, the case of the draw false twisting machine has been described as the bobbin processing machine. However, in the case of inspecting packages doffed from many spinning winders and putting them into a warehouse, Can also be applied. In this case, it is conceivable to attach a yarn outer diameter inspection device to each weight of the spinning winder and rank the quality of the yarn based on the presence or absence of fluff.
