Abstract

PURPOSE:A motor for driving draft rollers and another motor for driving spindles are installed separately in the spinning frame, and they are controlled in their rotations so that the ratio of the rotation numbers attains a prescribed value to facilitate changes in conditions of spinning operations and reduce yarn breaks at the start and stop. CONSTITUTION:In a spinning frame where a silver or roving is drafted with plural couples of rollers 1,1'; 2,2'; 3,3', spun with the spindle 8 and wound up around the bobbin fitted to the spindle, the motor 10 for driving bottom rollers in the draft part 1, 2 and 3 and the other motor 4 for driving spindles 8 are installed separately and controlled by the controlling means 13 so that the ratio of the rotation number of the spindle 8 to the front bottom rollers becomes a previously set value.

Conventionally, as shown in FIG. 1, the plurality of bottom rollers 1, 2, and 3 receive their driving force from a drive motor 4 at the same end side via a drive shaft 5 and a gear mechanism. The other end of .3 is rotatably supported. However, in order to change the spinning conditions, it is necessary to replace the change gear among the gears in the gear mechanism. Therefore,
In order to relieve this complexity, a method can be considered in which the bottom rollers 1, 2 and 3 are individually driven by a synchronous motor. However, this driving method induces non-uniformity of the yarn due to mismatch in synchronization, and is difficult to put into practical use, especially because of the difficulty in synchronizing when starting and stopping the machine.

On the other hand, the number of twists determined by the rotational speed ratio of the front bottom roller 3 and the drive shaft 5 does not require strict setting as in the draft state, and the permissible variation range of the number of twists is smaller than the permissible variation range of the draft. Much thicker. Therefore, as shown in FIG. 1, the front bottom roller 3 and the drive shaft 5 are connected to the gear 9V? - There is no need to limit the method to driving by a single drive motor 4 with two operative connections.

In this embodiment, the bottom rollers 1, 2.3 and the drive shaft 5 (hereinafter referred to as spindle drive shaft) are not operatively coupled, and instead, the front bottom roller 3 is connected to the drive morph 4 (hereinafter referred to as spindle drive motor). The drive motor 10 is connected to a separate drive motor 10 (which is capable of forward and reverse rotation). or,
The spindle drive shaft 5 and the flow/tobottom roller 3 are each provided with a rotation speed detection device 11, 12, such as a magnetic or optical system, and the detection device 11 emits a number of pulses A1 per rotation of the spindle drive shaft 5, and detects the number of pulses. The device 12 emits a number of pulses A2 per revolution of the front bottom roller 3. Both pulse signals are sent to a control circuit 13 that controls the rotation of both drive motors 4 and 10.

When a stop signal is input to the control circuit 13, the circuit 13 sends an operation stop command to the bottom roller drive motor 1o.
After a preset time, an operation stop command is also sent to the spindle drive motor 4. That is, the spindle and drive motor 4 Vi stop a little later than the bottom roller drive motor 10 . Therefore, the twisted fleece F between the front bottom roller 3 and the spindle drive shaft 5 is in a relaxed state, and yarn breakage, which is likely to occur when the machine is stopped, does not occur.

In this embodiment, the rotational relationship between the front bottom roller 3 and the spindle drive shaft 5 when the machine is started and stopped is such that the start and stop of the bottom roller 3 and the drive shaft 5 are staggered by a preset time difference. Since it is programmed in a shape, it is possible to suppress the occurrence of thread breakage when starting and stopping the machine. The programming method is not limited to this embodiment. For example, at startup, when the number of pulses from the detection device 11 that detects the rotation speed of the spindle drive shaft 5 reaches a preset value, the - An operation command is sent from the control circuit 13 to the roller drive motor 10, and when the motor is stopped, when the number of pulses from the detection device 12 that detects the rotation speed of the front bottom roller 3 reaches a preset value, the spindle A stop command may be sent to the first drive motor 4 from the control circuit 13.

The setting of the number of twists can be changed by simply inputting a setting signal indicating the rotational speed ratio between the spindle drive shaft 5 and the front bottom roller 3 to the control circuit 13 by operating a button or the like.
The twisting direction of the yarn is also changed by switching the spindle and the drive motor 4 between forward and reverse directions, and this operation is very easy, unlike the conventional structure that requires the troublesome work of replacing the change gear.

In ring sheath spinning machines and the like, conventionally, the ring plate has obtained its driving force from the drive motor 4. However, fluctuations in the lowering speed IW of the ring plate determine the pinch of the yarn wound onto the bobbin. As in the case of the number of twists, the permissible range is much larger than the permissible variation range of the draft, and it is possible to drive the ring plate by a drive motor separate from the spindle and the drive motor 4. Alternatively, the bottom roller 1 drive motor 10/spray 1.
