不安定にならない様に制御される。2. Description of the Related Art Generally, a winder such as a flat yarn has a system configuration in which several dozen independent units shown in the configuration of FIG. 2 and the block diagram of FIG. 3 operate as a set. Ten or more tapes are simultaneously supplied at a constant feed rate called line speed, and each tape is wound by a tension sensor called a dancer roll and a tension control device 2 that receives a tension detection signal from a potentiometer 1. It is wound by the take-up motor 3 and has a unit structure shown in FIG. In FIG. 2, 4 is a spindle driven by the winding motor 3 via the transmission 5, 6 is a dancer roll, 7 is a stop detection switch, and 8 is a tape to be wound. As shown in the unit block in FIG. 3, the operation is such that the tension command is determined at a certain line speed, the winding speed becomes slower so that the peripheral speed is kept constant as the bobbin diameter increases, It is also controlled so that the system does not become unstable due to disturbance.

るという問題があった。Problems to be Solved by the Invention However, in the configuration of the conventional tension control device that controls the winding speed command by the instantaneous value of the position of the potentiometer 1, that is, the dancer roller 6, the winding speed is low when the bobbin diameter is large. When the yarn breakage occurs at the speed (the yarn breaker tape is controlled so that it does not get entangled with the tapes of other units so that the tape is wound for a certain time and then stopped), the dancer roller 6 falls. Since the winding speed command becomes high and the dynamic balance of the bobbin is imperfect, abnormal vibration occurs and there is a problem that the machine life is significantly reduced.

よっていた。In addition, when the initial winding and the restart winding when the thread is broken, the dancer arm is lifted by hand and the dancer arm position is adjusted so that the operator can "can according to the skill level" to obtain an appropriate winding speed. I used to rely on the "familiarity" of the workers who hang up.
また、上記手作業による巻掛けが非常に困難であるため
ラインスピードの高速化による巻取能率のアップが出来
なかった。Further, since the above-mentioned manual winding is very difficult, it was not possible to increase the winding efficiency by increasing the line speed.
さらに、巻取径が大きくなると第３図の慣性負荷による
応答性の遅れにより系が不安定になる為、ボビン径を大
きくするにも一定の限界があった。Further, when the winding diameter becomes large, the system becomes unstable due to the delay in response due to the inertial load shown in FIG. 3, so there is a certain limit in increasing the bobbin diameter.

かじめ設定された適正な高速指令yBの巻取指令で始動し
初期巻掛けが行われる。First, during the initial start-up winding, the bobbin diameter is small and it is necessary to wind the bobbin at high speed. The winding speed command changeover switch unit 22 shown in FIG. 1 includes a state command circuit 26 and a switch changeover circuit 28.
Thus, the initial winding speed command circuit 23 starts the winding operation with an appropriate high speed command yB preset by the initial winding speed command circuit 23, and the initial winding operation is performed.

り状態に影響を与えない。Next, the changeover switch unit 22 is switched to 22A by the state command circuit 26 and the switch changeover circuit 28, and the tension control circuit 21 enters the primary steady-state winding state by the main feedback control according to the instantaneous winding instruction yA. In the latter half of steady winding, when the bobbin diameter becomes large, the inertial load becomes large, the hunting becomes large due to the delay of the mechanical time constant, and in the worst case, the state becomes unstable and thread breakage occurs due to overhunting. In this way, in the secondary steady-state winding state in which the bobbin diameter has increased, the bobbin diameter is large, so the change in the winding speed (command) with time is small, and the winding speed is the same for several tens of seconds. However, it does not affect the finished state of the winding.

を行い再運転される。The average value circuit 25 averages the winding speed equivalent signals in the steady and stable winding state, and passes through the memory circuit 29, so that the average winding signal yC that changes slowly with time of the average winding command circuit 24 is operated. The state command circuit 26 and the switch changeover circuit 28 change the connection of the winding speed command changeover switch section 22 to 22C, and the second steady winding state is taken up. When winding is completed, the winding motor 3 is stopped, the bobbin is replaced, the winding is restarted, and the operation is restarted.

御する。When thread breakage occurs, the tape 8 to be wound up shown in FIG.
Due to the slack, the dancer roll 6 falls and the stop detection switch 7 shown in FIG. 2 is turned "ON", and it is detected that a yarn breakage has occurred. Average winding speed yC in the secondary winding state
Since there is no problem because it is driven by, the instantaneous winding speed command yA is commanded in the primary winding state, so when the dancer roll 6 falls, it becomes a high speed command, and when the bobbin diameter is large, it becomes a high speed command. The dynamic balance is poor and the machine may vibrate abnormally, resulting in dangerous and shortened machine life. In response to a yarn breakage detection signal such as the above stop detection switch signal, the state command circuit 26 controls the switch switching circuit 28 to switch the winding speed command switching switch section 22 to 22C and connect it to the average winding speed command. , Sends a set signal to the memory circuit 29 and gives a command to the memory circuit 29 to store the winding speed command of the average value circuit 25 immediately before the occurrence of yarn breakage. Winding speed command
Control to stop after winding the thread break tape for a certain time with ym.
次に糸切れ発生時の再始動巻掛けについて説明する。Next, restart winding when a yarn breakage occurs will be described.

The average winding speed ym stored in 29 is an appropriate winding speed for performing the winding start. At the time of restart winding, the winding speed changeover switch unit 22 is connected to 22C, and the winding speed ym stored in the memory circuit 29 is commanded to perform winding. If the yarn breakage occurs in the secondary steady state, the memory circuit 29 is reset and the secondary steady state is controlled.
Alternatively, if it occurs in the first steady state, the winding speed changeover switch unit 22 is controlled so as to be connected to 22A after the completion of winding, and the first steady winding state by the instantaneous winding instruction yA is controlled. Becomes
