[0031]
Next, in the yarn splicing device for dissimilar yarns according to the present invention, the configuration of the length measuring / reserving portion disposed between the yarn splicing portion 13 and the winding portion 15 will be described. The length measuring / reserving section is constituted by a length measuring / reserving device 20 for measuring the length of the selected winding yarn and temporarily storing the winding yarn. A specific example of the length measurement / storage device 20 is shown in FIG. The length measuring / storage device 20 according to this embodiment includes a stationary machine body 45 and a unique rotational drive source M1 attached to a suitable stationary system structure (or the stationary machine body 45).

On the other hand, the length measuring / storage member 55 includes a storage drum portion 57 that is tapered toward the one end side 55a, and a stopper flange 58 provided on the tapered front end side. .
[0033]
In relation to the length measurement / storage member 55 in the length measurement / storage device 20, a first position detection sensor 59 and a second position detection sensor for detecting the winding amount of the yarn wound around the storage drum portion 57. 60 is provided, and a yarn guide 61 for guiding the yarn drawn from the storage drum portion 57 is provided.
[0034]
In the length measuring / storage device 20 having the above-described configuration, the unique rotational drive source M is drawn during the yarn Y withdrawal period. ₁ When the branch portion 49 provided on one end side of the rotating member 47 rotates around the length measuring / retaining member 55, the yarn Y drawn from the branch portion 49 of the rotating member 47 is The length measuring / reserving member 55 is successively drawn in the direction of arrow a along the tapered surface of the storage drum portion 57 and is temporarily stored before being wound on the winding package.
[0035]
In this configuration, the rotational drive source M ₁ Is constituted by, for example, a pulse motor, and the circumference of the storage drum portion 57 is set in advance in units of mm, so that one rotation of the pulse motor = the circumference of the storage drum portion 57 (mm) Thus, the length of the selected back yarn can be calculated from the number of rotations of the pulse motor, and the length of the selected back yarn can be measured within an error range of several millimeters. The rotational drive source M ₁ May be a stepping motor or a servo motor instead of the pulse motor.

Next, the yarn splicing winding control of different yarns in the above apparatus will be described. In the present invention, first, the yarn type to be wound and the length of the yarn type are input and set to the control unit 16 in order to wind. In this case, the length of the selected yarn is the pulse motor M ₁ Is automatically converted to the number of pulses to be output or set as the number of pulses. Since the circumferential length of the storage drum portion 57 is known in advance, the pulse motor M ₁ The number of pulses required for one rotation and the length of the yarn wound from the circumference are set as the number of pulses. Accordingly, the length of the yarn to be wound can be set in units of mm.
[0038]
In the normal winding operation, when the selected yarn is wound around the storage drum unit 57 by the set length, the pulse motor M is in response to a command from the control unit 16. ₁ Is stopped and the next preset type of yarn is selected and spliced with the previous yarn. During this splicing operation, the motor M on the winding unit 15 side ₂ Continues to rotate, and the yarn stored in the storage drum portion 57 is wound around the package P. When yarn splicing is completed, the pulse motor M ₁ Is driven and rotated by the number of pulses corresponding to the set length of the newly stored yarn. In this way, the yarn of the preset type and length is wound around the package P.
[0039]
Usually, the storage speed (motor M ₁ Is the winding speed (winding motor M). ₂ However, if the yarn splicing operation is frequently performed, the stored yarn decreases, and the decrease position detection sensor 59 may detect the absence of the yarn. At this time, the winding motor M ₂ Is temporarily stopped, and the storage operation of the yarn to the storage drum portion 57 is prioritized. When the yarn is wound around the storage drum portion 57 and the position detection sensor 59 detects the presence of the yarn again, the winding motor M ₂ Is driven to rotate again. The winding motor M ₂ It is also possible to store while continuing the winding by decelerating control without stopping.
[0040]
On the other hand, when the set length of the selected yarn is long, the yarn splicing is not performed frequently, so that the winding amount around the storage drum 57 increases, and the position detection sensor 60 for detecting the maximum position has the yarn. Is detected, the motor M ₁ Is stopped and the winding motor M ₂ Rotate only to give priority to winding. When the amount of yarn on the storage drum 57 decreases and the position detection sensor 60 for maximum position detection detects the absence of yarn, the motor M again. ₁ To resume the storage of the yarn on the storage drum 57. In this case as well, the motor M ₁ Winding motor M without stopping ₂ It is also possible to reduce the amount of yarn stored on the storage drum 57 by increasing the rotation speed to continue the rotation and increasing the winding speed.
[0041]
In the winding control, the motor M is detected by the yarn presence or absence detection signal of the first and second position detection sensors 59 and 60. ₁ , M ₂ However, if a single yarn type length is relatively short, a winding speed (winding motor M) is controlled. ₂ Rotation speed) is set to a low speed, and when one thread type length is long, the winding speed is set to a high speed to enable efficient winding without stopping and driving the motor. Is also possible.
[0042]
