Abstract

PURPOSE:The amount of the draft adjustment corresponding to the positions of each winding-up length is set in such a range as the grain fluctuation of the lap caused by the fluctuation in the lap winding-up length can be adjusted, whereby the fluctuation in grain is adjusted, while the lap is wound up. CONSTITUTION:In the winding-up part 34, the position of the lap wound around the bobbin 37 is detected at each winding-up position that is set by dividing the total length of the full lap into predetermined lengths and the pulse generator sends out winding-up position signals. The draft amount at the draft part 14a is switched sequentially to the ones that are set by adding the draft adjustment that is previously determined corresponding to the each winding-up position, thus adjusting the lap grain according to the length of wound-up lap. The amount of the draft is varied with the speed regulator 45.

It is possible to correct the gel grain fluctuation of the wrap due to an increase in the length of the wrap during the removal of the wrap, and improve the quality of the wrap. The present invention provides a lap gelation correction method that can correct the gelation of the lap to improve yarn quality by correcting the gelation of the spun sliver that occurs in the process, and this method is well implemented. The present invention aims to provide a device that can obtain the desired results.

7, it is rotated via a synchro heald 48, a direction changing mechanism 49, a synchro belt 50, and a pulley 51 on the input shaft 46. A pulley 53 is fixed to the output shaft 52 of the transmission 45, and a pulley 54 is rotatably fitted to the shaft 151LA of the controller 15A.
A synchro belt 55 is suspended between the two.

The pulley 54 is integrally connected to a gear 56 rotatably fitted to a 70 roller j5A+/)u-ra shaft 15mA. This gear 56 is connected to the first and third heads s1.
It corresponds to the gear 22.221 of 1.11B and is meshed with the draft change gear 25^. Therefore, in the second head section 11A, the 70 controller 15Ati of the draft section 14m is 11. Like 11B, the back roller 16A is directly rotated by the countershaft 19, but the back roller 16A is rotated directly by the countershaft 19.
The zero rotation is transmitted by a predetermined amount by the transmission 45. The speed change amount of the variable mM45 can be changed to any desired magnitude by rotating the speed change shaft 570. Next, this winding part 3 is attached to the 58Fi winding part 34.
4, the winding position of the wrap L on the bobbin 37 is the full wrap L.
), the winding length detection device is attached to detect each winding length position and generate a winding position signal (IL). By detecting the amount of rotation of the take-up drum 360, each winding length position of the wrap L is detected.This winding length detection device 58

Pulse generation (winding amount A11 of the wrap L corresponding to one interval on the bobbin 37 is t-., then it is set to a value that satisfies the formula of P = E / e N, and the lap L is set to a value that satisfies the formula of bobbin 37 > 57 K K
,/' Every time N (:Pa) is wound, that is, wrap 1. Each time the winding length M-IJ reaches the winding position on the bobbin 37, step switching No. 16, which is exemplified as a winding position signal, is transmitted. Next, 66 is a driver 7) MIE amount setting device configured to be able to set the draft catch value corresponding to each winding length position in advance, and in the same song, they are arranged parallel to each other (N+1 ) slide volume 634L illustrated as variable resistors
These slide volumes 63a correspond to each winding length position sequentially, and each draft correction amount is set by these slide volumes 463a [], 66a1...・＜S3
&N (hereinafter collectively referred to as slide volume 65&)
It can be set using the voltage value. next,
Reference numeral 64 indicates the gear shift amount of the gear shift Ia 45 of the #2 head portion 11A according to the step change signal from the winding length detection device 58. This is a control device for switching sequentially to the following L. First, the transmission 4
5's strange M! A gear 65 is fixed to the shaft 57, and this gear 65
is meshed with a gear 67 fixed to the rotating shaft 66a of the pilot motor 66. The pilot motor 66 is configured to be rotated forward or reverse by an operation signal from a pilot motor control circuit 68 which is transmitted in accordance with the calculation result of a calculation circuit which will be described later. Further, the speed change shaft 57 has a UII
The detection shaft of the speed change detected device 69 using a variable resistor is connected, and the change i! ! ! ! The amount of shift by the pilot motor 66 of the I45 is detected as a voltage value by the shift detection device 69, and this voltage value is fed back to an arithmetic circuit which will be described later. The magnitude of the voltage value output by the shift amount detector 69 is determined by operating the pilot motor 66 so that the draft portion 14A is compensated for the draft by the draft correction amount set by the draft correction Iik setting device 63. When the draft correction amount is set, it is first set to be equal to the set voltage value of the seed 16 . 7
0 is a stepping relay for connecting the slide polycomb 63 of the draft correction amount setting device 66 corresponding to the step switching ft No. 1 by the step switching signal from the winding length detector [58] to the calculation@path described later. , a drive coil 70&, and a large number of contacts 70b, and by switching these contacts 70b, draft correction amounts corresponding to each winding length position of the wrap L can be sequentially input to the calculation circuit 71. . The arithmetic circuit 71 compares the voltage value from the draft supplementary +E tIk setting device W65 with the voltage value from the shift detection device 69, converts the deviation into a speed increase signal or a deceleration signal, and outputs the pilot motor control 1111m path 68.
It is designed to be sent to Next, 72 is a pilot motor for controlling the lamp cover which is controlled via the control circuit 73 based on the deviation value of the lap meter FI 145, and the detection shaft 74a of the variable resistor 74 is connected to the rotating shaft 72&. The lap weight correction value corresponding to the deviation value can be adjusted by 1 and output as a voltage value. The voltage value from this variable resistor 7414 is used for draft correction in the arithmetic circuit 71! It is added to the voltage value from the setting device 63.

In the above configuration, before starting the work of winding the wrap L, first, the draft correction amount of each slide volume 65 & of the draft correction amount setting device 63 and the reference setting weight of the lap measuring device 430 are set. The magnitude of the draft correction amount of each slide volume 65h can be determined by unwinding the full wrap + IL that has been wound up with the wrap pomer in advance and measuring the gel at each winding length position of the wrap L that occurs during lap winding. Based on the data obtained from the winding process, the size is set to be such that it can correct the grain fluctuation at each winding length position. Further, in this case, if necessary, each draft correction amount may be set so as to also correct gel grain fluctuations of the spun sliver in the comber and drawing machine in the subsequent process. The roughness # of the wrap L accompanying winding of the wrap B with the above-mentioned wrap homer increases as the number of winders of the wrap L increases, so each draft correction amount becomes A15 near the end of the winding. The setting is made such that the draft at the draft portion 14A becomes larger as the temperature increases. In addition, in the comber, as the lap diameter becomes smaller, the bobbin of the spun sliver becomes slightly larger, so in order to compensate for this gain variation, it is necessary to Set the correction amount for each trough so that the L bobbin becomes slightly smaller, and as the amount of sliver supplied in the can of the wire threading machine decreases, the bobbin of the spun sliver becomes slightly smaller, so this bobbin fluctuation is corrected. In order to do this, each draft correction amount may be set so that the bobbin of the wrap becomes slightly larger as the amount of wrap L is wound up by the wrap homer. Next, the motor 6 of the lap homer is rotated to start the winding operation 9 of the lap L, but due to the start of this winding operation, the stepping relay 70 of the control device 64 is set to the first step. First slide volume 63 of draft correction amount setting device W165
A voltage value corresponding to the draft correction amount multiplied by &0 by 12511 is input to the arithmetic circuit 71. As a result, the rotation of the pilot motor 660 rotating shaft 66& is controlled so that the voltage value from the speed change amount detector 69 becomes equal to the voltage value from the slide volume 63aO, and the draft amount of the draft portion 14A changes from - to that of the slide volume 63aO. - Control the shift amount of the transmission 45 so that it takes into account the draft correction amount. Therefore, the lamp L that is supplied from the second head section 11A to the lap conveyor 1 is drafted with a draft amount that takes into account the draft correction amount of the slide volume 63aO, and is wound up by the winding section 34. The bobbin is controlled. On the other hand, when the motor 6 is driven to rotate and the winding drum 36 is rotated as described above, the pulse generator 59 of the winding length detecting device 58 detects that every predetermined rotation angle of the winding drum 36, that is, the lap L is 37, a pulse signal is emitted every time a predetermined length is wound, and this pulse signal is input to the preset counter 62t/C. Then, when the count number of this preset counter 620 reaches a preset count setting value, this preset counter 62 issues a subtsubu switching signal (m and Stella Pin Buri -70
is input to the drive coil 70m. As a result, the contact 70b of the stepping relay 70 is now switched to the second step, and the second X 5 I Fd? IJ Neem 6
A voltage value corresponding to the draft correction - set in step 311 is input to the arithmetic circuit 71i1j, and the draft layer of the draft section 14A is adjusted to the slide volume 66a1 in the same way as above.
It is controlled to have a value that takes into account the draft correction amount. - The step switching signal F is generated when the winding position of the wrap ■ onto the bobbin 67 reaches a preset winding length position, and the slide volume 66&1 corresponding to this winding length position is emitted. The draft JIt of the draft section 14A is corrected by the draft correction amount. E, L
In this way, each time the winding position of the lap L onto the bobbin 57 reaches the nominal winding length position, the preset counter 62 sends a step switching number fJ, and the stepping relay 70 is sequentially switched up to the final step. ))j-1+7)
The draft portion 14A is sequentially switched to a draft amount that takes into account the draft correction amount set corresponding to each winding length position.
The draft amount of A is changed according to the winding length of wrap L onto the bobbin 67. As described above, the draft M correct amount of each slide volume 63 & of the draft correction setting device 63 is set to a size that can correct bobbin fluctuations at each winding length position as the lamp L is wound. Because there is, the second
The wrap Ld of the head portion 11A is drafted so as to correct the above-mentioned gellen fluctuation. Therefore, in the full wrap La where the winding of the lap L has been completed, the bobbin fluctuations accompanying the winding of the lap L have been corrected. After winding of the wrap L is completed, the full wrap L & on the winding drum 55.36 is placed on the wrap measuring device 43 and its weight is measured, based on the deviation value between the measuring device and the reference setting weight. The pilot motor 72 is rotated, and a lap weight M correction value corresponding to this deviation value is input to the arithmetic circuit 71. Therefore, when the next wrap L is wound, the overlapped edge fluctuation of the full wrap La is also corrected. Note that when the stepping relay 70 is switched from the final step to the first step (19)
Since the draft amount of ^ is changed greatly and large unevenness of lap occurs, it is preferable to check the lap LO at low speed until this changeover is completed so that the large coal portion of the lap L becomes short. Therefore, it is advisable to attach a low-speed motor separately from the motor 6 via a clutch.
Although it is designed to detect winding length positions at approximately intervals, a timer may be used to detect winding length positions at irregular intervals. Further, the pulse generator may be configured to generate pulses by rotating the countershaft or the like.In addition, the winding length detecting device detects the winding drum (hf) and the bobbin's top cover. Alternatively, the winding length of the wrap may be detected. In addition, in the above example, J5
In C, the draft sleeve Masatoshi setting device is constructed with a large number of parallel slide volumes, so it has the great feature that the draft compensation setting value can be viewed directly as a single curve, but it is not limited to this. .

As described above, in the present invention, when winding the wrap onto the bobbin, when the winding position of the wrap onto the bobbin reaches each winding length position that divides the entire length of the wrap with the full ramp foreshadowing into a predetermined number, the draft part The draft amount of is sequentially converted to the draft amount of 9J, taking into account the draft adjustment preset corresponding to each winding length position mentioned above, and the gelation of the wrap is corrected according to the winding length of tlyp. Therefore, when forming a wrap, if the draft capture amount corresponding to each winding length position is set in advance to a size that can compensate for the gel grain fluctuation of the wrap caused by fluctuations in the winding length of the wrap, the wrap can be easily formed. It is possible to correct gelation fluctuations due to changes in the winding length during winding of the wrap, and there is an effect that the quality of the wrap can be reliably improved without reducing the forming ability of the wrap. In addition, each of the above-mentioned drafts is used to control the grain fluctuations of the spun sliver caused by fluctuations in the lap diameter in the comber in the subsequent process, and the grain fluctuations of the spun sliver caused by fluctuations in the can storage lid of the supplied sliver in the filament. If it is set to a size that can compensate for the sliver, the grain of the wrap can be corrected during winding of the wrap so that it can also compensate for the fluctuation of the grain of the spun sliver that occurs in the comber or wirer. Even when changing wraps in the comber and cans in the filament machine at the same time to improve work efficiency, it is possible to prevent gel grain fluctuations in the spun sliver of the filament machine, which have the greatest impact on yarn quality. This has the effect of significantly improving yarn quality as it can be made significantly smaller than the previous one.

In addition, in the present invention, the wrap machine is equipped with a transmission capable of changing draft wrinkles, and the winding position lf of the wrap on the bobbin is divided into the total length constant of the wrap in the full wrap state. A winding length detecting device is installed to detect when the winding position has been reached and transmit the winding position number 6, and a draft winding length detector corresponding to each winding length position of the wrap is further provided. A control device 22 is provided with a draft correction amount setting device that can set a draft correction amount for each part, and the control device 22 controls the gear position of the transmission to adjust the winding length according to each winding position signal from the winding length detecting device. (trough) of the draft correction amount setting device corresponding to the position of the draft correction amount setting device. With the simple operation of setting each draft capture amount to the desired size, it is possible to eliminate gel grain fluctuations due to an increase in the winding length of the wrap, and to prevent spun sliver in the post-process comber or filament machine. It is possible to mechanically correct the gelation of the wrap during wrap winding so as to correct the gelation fluctuation of the wrap, and even an unskilled person can easily correct the gelation of the wrap. In addition to attaching a transmission and a winding length detection device to the lap machine as shown in the figure, the configuration is only to include a draft correction IIk setting device and a control device, so it can be implemented on an existing conventional lap machine. However, it can be implemented with little cost and time.
