Abstract

PURPOSE:To provide a spindle drive controlling apparatus allowing easy input of preset values and capable of smoothly performing the running-in of an ultra- high speed fine spinning frame after the exchange of traveler at the initial stage of spinning. CONSTITUTION:Each time the doffing operation is carried out during running-in of a spinning frame, the rotational speed of a spindle in each zone Z1 to Z4 from the start of winding to the full-bobbin state is increased stepwise by successively adding the increments DELTAL1 to DELTAL4 to the preset standard rotational speeds L1 to L4 of the running-in operation. The rotational speed is returned to the normal level when the accumulated spun length (output) after the exchange of a traveler during the running-in reaches the preset running-in output.

2. Description of the Related Art In a ring spinning machine, a thread is wound on a bobbin via a traveler that slides on a ring flange. This traveler wears due to friction with the ring flange, so it is replaced at regular intervals (about two weeks). After the traveler is replaced, the run-in operation is performed at a speed slower than the normal spindle rotation so that the traveler and the ring flanges fit together and the traveler slides smoothly on the ring. To prevent.

Various techniques for shifting from the running-in operation to the normal spinning operation have been proposed for a recent ultra-high speed spinning machine (spindle speed during normal spinning is 18000 to 25000 rpm). For example, in Japanese Unexamined Patent Publication (Kokai) No. 3-104935, the spindle rotation from the spinning start to the stop of the spinning machine is gradually changed, and a plurality of shift patterns having different maximum rotation speeds are preset and stored. Select the required speed change pattern from the change speed pattern according to the type of traveler and spinning conditions, and combine it to gradually increase the maximum rotation speed of the spindle from the break-in operation to the normal spinning speed for each doffing. It is disclosed that the speed is increased.

In the ultra-high-speed spinning machine as described above, the initial spinning (1 to 3 minutes) and the high-speed spinning (3 to 3 minutes).
In the former, the distance between the traveler 8 and the snare wire is long and the ballooning is large, so the traveler 8
Receives thread tension in a substantially horizontal direction, and its posture is ring 7a.
However, since the latter has a small ballooning, the traveler 8 tilts obliquely upward due to the tension (FIG. 5 (b)). Therefore, the traveler 8 has a different sliding contact surface with the ring 7a at the initial stage of spinning and at the time of high-speed spinning. In addition, the hardness of the high-speed spinning machine is higher than before in order to guarantee the service life of both the ring and the traveler, and the break-in time at low-speed rotation is longer than at high-speed rotation. The break-in operation of the traveler 8 needs to be properly performed both at the time of departure.

In the above-mentioned prior art, since the maximum rotation of the spindle during the running-in is gradually increased, the traveler can be said to be easy to fit into the ring during high-speed spinning, which is preferable, but the ballooning is small and stable during high-speed spinning. Since there is little yarn breakage at all, there is no problem even if the running-in rotation is repeated several times at the same speed during high-speed spinning, and then the running-in rotation is immediately increased to the normal high-speed rotation. Rather, the ballooning is large, and the fluctuation of the yarn tension is large.
In addition, due to the requirement for efficient operation during the initial spinning even during the running-in, the spindle rotation during the initial spinning during running-in is gradually slowed down from the running-in rotation that is lower than the speed during the initial spinning during normal running. It was found by the applicant that it is important to raise it so that the traveler is sufficiently adapted to the ring in the early stage of spinning in order to prevent yarn breakage and improve productivity.

When increasing the initial break-in rotation in 10 steps, the speed pattern from the start of spinning to the stop must be set and stored respectively corresponding to the 10-step break-in rotation, and there is a problem that it takes time to input.

According to the above, during the running-in after the traveler is exchanged, the spindle rotation in the initial stage of spinning is calculated from the reference rotation and the speed increase, and the running-in rotation in the initial stage of spinning is increased stepwise. This allows the traveler and ring to become familiar with each other in the early stage of spinning. In addition, even if the running-in rotation in the initial stage of spinning is gradually increased in this way, since the spindle rotation is calculated from the reference rotation and the increased speed, it is not necessary to input many speed patterns and the setting input There is no hassle.

Go to 5. At step S5 corresponding the speed data memory for each section Z 1 to Z 4 reads the reference rotation L 1 ~L 4,
Based on the spinning length data from production detector 22, and outputs a speed command to the inverter 5 as the spindle rotation in each section Z 1 to Z 4 is the reference rotational speed L 1 ~L 4. The inverter 5 shifts the drive motor 4 stepwise by this.
Then, in step 6, the spinning length data from the production amount detector 22 is integrated, and in step 7, it is determined whether or not the integrated value has become the running-in production amount LL. The running-in production amount LL is at least 0 in this embodiment. Since the rotation speed of the 1.5 minute ball section Z 1 is 0.95H 1, it will be stopped when it is continuously wound up to a full tube (step 8),

As described above, in the present application, the stepwise acceleration is performed 10 times in 1% steps in the section Z 1 and 5 times in 2% steps in the section Z 2. Good driving. In addition, since the stepwise speedup is also performed in the zone Z 3 , the traveler's running-in operation is extremely well performed in the high speed range. Since the speed command for this gradual speed increase is calculated from the reference speed and the amount of speed increase, it is not necessary to set and input all many shift patterns, and it is easy to change the patterns. Further, in the present embodiment, the pattern of performing the traveler running-in operation after the doffing has been described, but according to the present invention, the optimal running-in condition is set at each gear shift stage, so that the running-in is started at any stage during spinning. Good.

As described above, according to the present invention, at least the spindle rotation at the initial stage of the spinning-out during the running-in operation is calculated from the reference rotational speed and the increased speed, and the drive motor is instructed. The running-in speed can be increased stepwise, and as a result, the traveler easily fits into the ring at the initial stage of spinning, and the traveler rotates smoothly, so that yarn breakage can be prevented. Moreover, since the spindle rotation at the initial stage of spinning in the running-in operation is calculated from the reference rotational speed and the increased speed, even if the spindle rotation at the initial stage of spinning is increased in multiple stages It is not necessary to set the rotations individually, and the trouble of inputting them is eliminated. Furthermore, since the reference number of revolutions and the amount of speed increase can be set freely, optimum running-in operation can be performed according to the type of traveler and spinning conditions.
