As shown in Figure 8, prepare a graph in which the vertical axis is the ratio Δ (percentage) of the change in count relative to the standard count, and the horizontal axis is the spinning length (cm), and the desired product is displayed on this graph. The pattern of the special thread 61 is expressed as a polygonal line 71. In this case, the rate of change in count is based on the standard count of O,
A case thicker than this is indicated by a plus value, a case thinner than this is indicated by a minus value, and the reference unit length La of the spinning length I7 is, for example, 1 cm, and the maximum length of the pattern setting length Ln is 70 m.

By starting this program, first input
In step 2, select whether to enter data from the keyboard or tape recorder, and when the keyboard input signal is input, proceed to the next "initial input" step (■).

In this "initial input" step (2), the ratio AO of change in the number to the reference number at the start time is inputted from the input device 68.

Note that the spinning length LO is set to zero by inputting the ratio AO. Once this initial input is done, proceed to the next step ``Count data Ln-An manual'', and this Stella
For one customer, the spinning length Ll and the count change ratio Al at the first bending point P1 of the pattern on the graph are input. When Ll and A1 are input, the process advances to the next step fi of determining end, and if no end signal is input at step

With the above steps, the pattern setting of the special yarn to be manufactured is completed. Incidentally, when it is desired to store the data LO to Ln and Δ0 to An related to the number change stored in the above-mentioned tα device 66 on a cassette tape for safekeeping.

If you need the data written on the cassette tape in this way at a later date, set the cassette tape in the tape recorder 70, and input a manual signal to the tape recorder in step ``Input'' of the program. Proceeding to step (2) of ``Reading data from cassette tape'', the data on this cassette tape can be stored in the storage device 66 again. As mentioned above, the pattern of the special thread 6I can be set easily and in a short time by inputting desired data from the manual device 68, and various different patterns can be set easily and in a short time. data on cassette tape (or disk)

The RAM of the storage device 73 constitutes a storage means for storing control data of a pattern set by the first computer device 63, and is configured to sequentially store control data input from the first computer device 63. ing.

Further, the ROM of the storage device 73 has written therein a main program shown in the flowchart shown in FIG. 9 and a spin program shown in the flowchart shown in FIG. 10. The main program and the spin program are started by turning on the start switch on the operation panel 77 after starting the spinning operation of the broken table. This spin program is based on the detected value CNI of the first pulsar 56 and the second pulsar 5.
This is for inputting the detected value CN2 of 7 and storing it in the RAM of the storage device 73. In figure 5, interrupt processing is performed every 0.2 seconds, and the detected values GNI and CN2 at that time are input and stored. The information is stored and updated in the RAM of the device 73.

Next, the operation of the drive system 3 based on the above main program will be explained. First, when the drive motor 4 is rotationally driven, the shaft 5a, pulley 5b, and belt 6 are rotated in the direction of the arrow, thereby rotating each rotating rotor l. Further, the rotational origin of the shaft 5a is the first body movement mechanism 15. First transmission 1
1 is transmitted to the delivery roller 7 via the first differential pulley 30 and the second transmission groove 19, and the delivery roller 7 is rotated in the direction of the arrow. Further, the rotation of the output gear 16 of the first differential gear 3o in the direction of the arrow is controlled by the third transmission Kl single gear groove 23,
It is transmitted to the feed roller 9 via the second differential tooth 1 (144) of the second transmission 21 and the fourth transmission mechanism 27, and rotates the feed roller 9 in the direction of the arrow. Rotation between the delivery roller 7 and the feed roller 9 The ratio is set so that the spun yarn of the reference count is spun from the rotating rotor 1 when the rotation of the second servo motor 43 is stopped, and when the second servo motor 43 is rotated in the forward or reverse direction, the delivery roller 7 and The rotational speed ratio between the feed rollers 9 is changed to change the thread count (thickness) of the X1i yarn.

In addition, the rotational speed ratio between the pre-heli roller 7 and the rotary rotor 1 described in - is the set twist number suitable for the spun yarn count (for example, I'6 number where the twist coefficient is a command value of 3 to 5). ), and when the first servo motor 29 is rotated in the forward or reverse direction, the rotational speed ratio between the delivery roller 7 and the rotary rotor 1 changes, thereby changing the number of twists of the spun yarn. When the main program starts while the drive motor 4 is being driven to spin out the spun yarn as described above, the process first proceeds to the "initial setting value input" step (■), and in this step (■) the spun yarn is Standard count Ac, standard trough;・D
, twist coefficient K, respectively. The values of the reference number Ae and reference draft D are set by replacing the change gear, etc., as in the case of a conventional machine, and the twist coefficient is set to a desired value in consideration of the reference number Ae. A above
8. When the value of D is input, the process proceeds to step C of ``Next r pattern load'', and if the pattern rod signal is input, the process proceeds to step ■ of ``pattern rot'', and the pattern load signal is input again. If there is no ``machine operation determination'' step of the direct method (proceeds suddenly, and if the machine operation is in φtsuyu, proceed to the next step O of ``length measurement pulse determination''. In this step O, the second pulsar 57 When the sub-length pulse is sent from (measuring means), the next "servo motor rotation speed calculation"
Proceed to step ■.

This ;1+11 length pulse is such that the spun yarn has a reference pasting length La (
For example, it is transmitted every time a minute (1 cm) is spun. In the above step @, the rotation speed N1 of the first servo motor 29 and the rotation speed N1 of the second servo motor 4 are used to control the change in the count and the number of twists of the spun yarn at the sub-length spun length position by transmitting the length measurement pulse.
Calculate the rotation fJ, N 2 of 3.

The rotation speed 142 of the second servo motor 43 is based on the control data A related to the number change stored in the storage device 73.
Based on the first data AO of O-A n and the detected value of the second pulser 57 (representing the rotation speed of the delivery roller rough) stored by the interrupt processing, the rotation speed of the feed roller 9 is determined by the data AO. The size is calculated to control the number corresponding to the number. Further, the rotational speed N1 of the first servo motor 29 is determined based on the above data AO, the detected value of the first pulser 56 (representing the rotational speed of the rotary rotor 1), and a preset twisting coefficient at each rotation of the delivery roller rough. , ¥1. is calculated to a size that controls the twist coefficient of the spun yarn to a set value K. When these calculations are completed, proceed to step 0 of the next r-number change determination.
Since count change request number 1n has been input in step 0 (when manufacturing special yarn, turn on the snap switch for count change determination when operating the machine), the first rNl
, N2 output" step [phase], and the above step @
So reed, 11. The control values N1 and N2 are output to the first motor control device 79 and the second motor control device 80. As a result, the first motor control device 79 controls the rotation of the first servo motor 29 to control the rotation speed of the delivery roller 7 so that the number of twists of the spun yarn becomes a value corresponding to the set twist coefficient l<,
The second motor control device 80 controls the rotation of the second servo motor 43 to control the rotation speed of the feed roller 9 so that the count of the spun yarn corresponds to the control data AO. The request signal in step ◎ of the r number change determination J is selected by a selection switch attached to the operation panel 77.

Next, proceed to step (corner) of machine operation determination J again.
Repeat the second operation. Therefore, each time the second pulser 57 transmits a length measurement pulse, the second servo motor 43 and the first servo Controls the rotation of the motor 29. When the rotational speed of the feed roller 9 is increased by the rotational control of the second servo motor 43, the amount of fibers supplied to the rotary rotor 1 increases and the delivery roller 7
The number of spun yarns drawn out increases, and conversely, when the rotational speed of the feed roller 9 is reduced.

The count of the spun yarn becomes smaller. In addition, the first servo motor 29
When the rotation speed of the delivery roller 7 is increased by rotation control, the number of twists of the spun yarn decreases.On the contrary, when the rotation speed of the delivery roller 7 is decreased, the VS of the spun yarn decreases.
The number will be large. Therefore, by repeating the operations described in (2) and (2), it is possible to manufacture the special yarn of the pattern set by the pattern setting means, and by continuously repeating the manufacturing of the special yarn of the pattern L, the desired length can be obtained. Special yarn can be easily made into 10 cores.

In the above embodiment, the pattern setting means is implanted in the first computer device 63, but the pattern setting means is implanted in the second computer device 64. device 64
The pattern setting means may be constituted by: Further, a plurality of machines may be controlled by one computer set in the central control room. Further, the rotation speed of the delivery roller 7 is detected by calculation using the second computer device 64 from the detection value of the first pulser 56 and the rotation speed N1 of the first servo motor 29, and the second pulser 57 is omitted. The number of revolutions of the rotating rotor 1 is determined by the second pulser 57.
The second computer device 64 uses the detected value of the second pulser 57 and the rotational speed N2 of the second servo motor 43.
Alternatively, the first pulser 56 may be omitted.

By setting a desired special yarn pattern in advance, it is possible to make a desired change in count to a single spun yarn, and the twist coefficient of the spun yarn can be The number of twists can be changed as the count changes to obtain the required size, and as a result, it is possible to produce a strong special yarn with a unique texture that can be freely changed in the count. It also includes a pattern setting means for setting a pattern of count change regarding the length of the special yarn to be manufactured, and a storage means for storing control data representing the set pattern. Since the first transmission device and the second transmission device are controlled, various special yarn patterns can be set and stored in the storage means, thereby making it possible to create special yarn patterns with a wide variety of variations. It is possible to change the pattern of special thread easily and in a very short time, and is very effective as a second type of device that requires high-mix, low-volume production.
