DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A striatal delivery device according to the present invention will be described with reference to FIG. The striatum delivery device according to the present invention rotates the bobbin 2 by the delivery motor 31,
A delivery mechanism 3 that sends out the filament 1 wound around the bobbin 2 toward the guide pulley 8 and a travel that detects a change (deviation) in the travel position of the filament 1 traveling toward the guide pulley 8. Position detecting means 5, a traverse mechanism 4 for moving the bobbin 2 based on a change in the running position of the striated body 1, a position of the bobbin 2 moved by the traverse mechanism 4 is detected, and the bobbin 2 is moved based on the bobbin position. Position detecting means 6 for detecting the sending position of the striated body 1 sent from the vehicle, a control unit 7 for controlling the operation of the traverse mechanism 4 based on the detection results of the running position detecting means 5 and the bobbin position detecting means 6. Consists of

The traveling position detecting means 5 for detecting a change (shift) in the traveling position of the striated body 1 is composed of a right sensor 51 and a left sensor 52 which are installed so as to sandwich the striated body 1 from the left and right. When the running position of the striatum 1 traveling between the pair of left and right sensors changes rightward, the right sensor 51 detects a change (shift) in the running position of the striatum 1.

The change (deviation) in the running position of the filament 1 detected by the running position detecting means 5 is transmitted to the control unit 7, and the control unit 7 performs the traverse mechanism based on the change in the running position of the filament 1. By controlling the operation of the traverse mechanism 4, the traverse mechanism 4 moves the bobbin 2 to keep the running position of the striatum 1 constant.
For example, when the right sensor 51 detects a change in the travel position (a change to the right), the traverse mechanism 4 moves the bobbin 2 to the left, and the striatum 1 travels between a pair of left and right sensors. Adjust to Note that the bobbin 2, the right sensor 51, the left sensor 52, and the guide are provided so that the striated body 1 traveling between the pair of left and right sensors and traveling toward the guide pulley 8 is sent out perpendicular to the bobbin axis. Each of the pulleys 8 is arranged.

A traverse mechanism 4 for moving the bobbin 2 based on a change (deviation) in the running position of the striated body 1 detected by the running position detecting means 5 is a motor rotatable in both forward and reverse directions under the control of a control unit 7. The bobbin 2 is provided on a stage 21 fixed to the slider 43, comprising a ball screw 42 rotated by the motor 41, and a slider 43 screwed to the ball screw 42.

The stage 21 fixed to the slider 43 is provided with a support member (not shown) so that the stage 21 does not rotate with the rotation of the ball screw 42. Accordingly, the ball screw 42 moves in the rotation axis direction. Stage 21
The bobbin 2 installed above is disposed so that the bobbin axis and the ball screw 42 are parallel to each other, whereby the bobbin 2 moves in the bobbin axis direction. That is, the traverse mechanism 4
Then, the moving direction (left and right) and the moving amount of the bobbin are adjusted by the rotating direction (forward and reverse) and the amount of rotation of the ball screw 42 rotated by the motor 41.

Further, in the striated body delivery device according to the present invention, the traverse mechanism 4 is provided with a bobbin position detecting means 6 for detecting the delivery position of the striated body 1 based on the amount of movement of the bobbin 2. For example, a two-phase encoder that measures the moving direction (left and right) and the moving amount of the bobbin 2 from the rotating direction (forward and reverse) and the amount of rotation of the ball screw 42 is provided, thereby detecting the position of the bobbin 2 and The delivery position of the striatum 1 is detected based on the position.

The delivery position of the striated body 1 detected by the bobbin position detecting means 6 is transmitted to the control unit 7, and the delivery position of the striated body 1 is set to a required small number of winding sections from the bobbin flange, for example, the flange of the bobbin 2. From the control unit 7
Stops the operation of the traverse mechanism 4 for moving the bobbin 2 based on the fluctuation of the running position of the striatum 1. Thereby, in the required few winding section where the delivery position of the filament 1 is from the bobbin flange, the movement of the bobbin 2 is stopped and only the delivery of the filament 1 proceeds, so that the filament 1 is It will be sent from near.

Further, in the striatum delivery device according to the present invention,
In the traveling position detecting means 5 composed of sensors provided on the left and right of the traveling striatum, a sensor that detects a change (deviation) in the traveling position of the striatum 1 before the operation of the traverse mechanism 4 is stopped The traverse which has stopped operating by detecting a change (shift) in the running position of the striated body 1 by a sensor on the opposite side, that is, a sensor installed on the side opposite to the bobbin flange detected by the bobbin position detecting means 6. The operation of the mechanism 4 resumes.

FIGS. 2 and 3 show a method for delivering a striatum according to the present invention. In the striated body sending method according to the present invention, the traverse mechanism 4 for moving the bobbin 2 based on the variation (deviation) of the running position of the striated body 1 is provided with a traverse mechanism 4 that moves the striated body 1 a required number In the winding section, the operation is stopped.

The delivery of the striated body shown in FIG. 2 shows a state in which the traverse mechanism 4 is operated based on a change (deviation) in the running position of the striated body 1 and the bobbin 2 moves. As shown in FIG. 2, sensors 51 and 52 are provided on the left and right so as to sandwich the running striated body 1. When the running position of the striated body 1 changes to the right, the right sensor 51 The control unit 7 operates the traverse mechanism 4 to move the bobbin 2 to the left based on the detection of the fluctuation (deviation) of the body 1. This keeps the running position of the striatum 1 constant,
The striatum 1 travels between a pair of left and right sensors (51 and 52).

The delivery of the filament 1 shown in FIG. 3 shows a case where the delivery position of the filament 1 detected by the bobbin position detecting means 6 is in a required few winding section from the flange of the bobbin 2. In a required few winding section where the delivery position of the striated body 1 is from the side of the bobbin flange, the operation of the traverse mechanism 4 for moving the bobbin 2 based on the fluctuation (shift) of the running position of the striated body 1 stops. That is, when the delivery position of the filament 1 is detected by the bobbin position detection means 6 to be a required minor winding section from the right side of the bobbin 2, the operation of the traverse mechanism 4 is stopped and the right sensor 51 detects the operation. The fluctuation (deviation) of the running position is ignored and the bobbin 2 does not move, and the filament 1 sent out from the bobbin 2 to the guide pulley 8 fluctuates from the right sensor 51 and the left sensor 52 to the right. I do. Thereby, in a required few winding section from the bobbin flange, the striated body 1 travels from the vicinity of the bobbin flange.

Further, in the striatum delivery method according to the present invention,
When the striated body 1 excites the sensor installed on the side opposite to the bobbin flange detected by the bobbin position detecting means 6, the operation of the traverse mechanism 4 is resumed, and the striated body 1 is again activated.
The bobbin 2 moves based on a change (deviation) in the traveling position of the bobbin. As shown in FIG. 3, at the right edge of the bobbin detected by the bobbin position detecting means 6, when the delivery position of the striated body 1 reaches the bobbin flange, the moving direction is reversed from right to left. Accordingly, the striated body 1 that has shifted to the right from the position between the sensors 51 and 52 runs again between the sensors 51 and 52, and subsequently the left sensor 52 detects a change (shift) in the running position of the striated body 1. Will be detected. That is, in the striated body sending method according to the present invention, the striated body 1 is
By exciting the sensor installed on the side opposite to the bobbin flange detected in the above, it is recognized that the required minor winding section has ended from the bobbin flange, whereby the operation of the traverse mechanism 4 is restarted, The bobbin 2 moves rightward based on the change in the running position of the striatum 1 detected by the left sensor 52.

Therefore, the control unit 7 controls the operation of the traverse mechanism 4 based on the variation (deviation) of the running position of the striatum detected by the running position detecting means 5,
The traverse mechanism is adjusted so that the filament 1 travels perpendicular to the bobbin axis, and the delivery position of the filament 1 detected by the bobbin position detecting means 6 is in a required few winding section from the bobbin flange. 4, the movement of the bobbin is stopped, and only the delivery of the striated body is performed, so that the striated body 1 is adjusted to run from the vicinity of the bobbin tsuba. By confirming the end of the delivery position of the filament in the winding section by the traveling position detecting means 5, the operation of the traverse mechanism 4 is restarted, and the filament 1 is again adjusted to travel perpendicular to the bobbin axis. I do.
