A chuck 362 is provided at one of the intermediate portions of two adjacent guide units 348 in the sampling unit 342. The chuck 362 is configured to hold the cord 12 positioned by the guide unit 348 by holding portions 362A and 362B that can be opened and closed. As shown by the solid line in FIG. 16, when the sampling unit 342 moves to the mounting position, the chuck 362 opens and the cord 12
Is released, and the moving guides 356 and 358 move from the guide position direction to the standby position direction (the direction opposite to the arrow G direction and the direction opposite to the arrow H direction). It is designed to be placed on top.

Next, the operation of the present embodiment will be described.

In the present embodiment, the winding of the cord 12 on the spool 10 is decelerated a few meters before the winding of the cord 12 on the spool 10 stops at the specified length, for example, by the automatic control of the control device 34. At the same time, the hanger pulley (not shown) provided above the delivery roller 36 is raised to secure the length of the cord 12 for measuring the characteristics of the cord 12.

Thereafter, when the winding of the cord 12 onto the spool 10 is stopped, as shown in FIG. 4, the clip fixing pin 40 and the cord pressing pin 42 are moved in the direction of arrow B by the driving means automatically controlled by the control device 34. Move to. As a result, the clip 20 pressed by the clip stopper pin 40 is elastically deformed as shown in FIG. 4, and the cord stopper 20C is inserted through the through hole 44 formed in the flange 10A of the spool 10, and A gap is formed between 20C and the flange 10A.

On the other hand, the cord pressing pin 42 is moved in the direction of the arrow D by the driving means automatically controlled by the control device 34, thereby abutting on the cord 12, and connecting the cord 12 with the cord stopper 20C and the flange 10A. Press into the gap between. Thereafter, the clip fixing pin 40 and the cord pressing pin 42 move in the direction of arrow C, and the cord 1
2 is held by the cord stopper 20C of the clip 20.

Thereafter, the fusing chuck 50 moves as indicated by an arrow F shown by a two-dot chain line in FIG.

When the cord 12 is blown, the upper portion of the blown portion is held by a holder (not shown), and a residual stress measurement and a straightness measurement described later are performed.

When the cord 12 is blown, as shown in FIG. 1, the spool feeder 52 rises and moves to the receiving position shown by the two-dot chain line in FIG. 1, and supports the spool 10 from below.

When the spool 10 is supported by the spool feeder 52, a pair of left and right spool holding arms 2
4 and 26 are separated from the spool 10.

Thereafter, the spool feeder 52 is moved to the position shown in FIG.
In the direction indicated by the arrow G in FIG. 1 and the delivery position indicated by the dashed line in FIG.

When the spool 10 is set on the take-up shaft 23, the take-up servo motor 30 is operated by a signal from the control device 34, and the spool 10 is moved in a predetermined direction. Rotate in C direction. Simultaneously with this rotation, the color mark sensor 138 detects the core edge 126A of the spool 10, and stops the spool 10 at the detected position (measurement reference positioning).

Next, based on the data stored in the control device 34, the take-up servo motor 30 is again rotated by a predetermined amount α, and the code insertion hole 128 is located at the correction start coordinate substantially below the reflection type photosensor 136. To move.

Next, when the coordinates of the points B1 and B2 are detected, the control device 34 calculates the distance y between the points B1 and B2 from the coordinates of the points B1 and B2, and calculates the distance y between the points B1 and B2 by the following formula. The distance x from the center P of the code insertion hole 128 is calculated, and the coordinates of the center P of the code insertion hole 128 are obtained.

On the other hand, when the distal end of the cord 12 is inserted into the cord insertion hole 128, the two guides 132 and 134 are separated from each other to form a gap through which the cord 12 can pass. It moves to the evacuation position which is located on the back side of the paper of FIG. Further, when the spool 10 rotates and the winding of the cord 12 is started, the pair of delivery rollers 36 are separated from each other to release the holding of the cord 12, and then return to the upper standby position.
