直交する水平面内に配置するように装置している。Both the left and right lead wire positioning devices 8, 8 have a similar structure, and are mounted on a mounting board 9 fixed on the side substrates 5, 6.
As shown in the figure, a cube-shaped rotary table 10 is mounted so as to be able to reciprocate in a horizontal plane with a pivot shaft 11 provided vertically on the lower surface of the rotary table 10. A circular mounting hole 1 between the front and rear surfaces of the
2, and is attached in the front-rear direction of the rotary table 10 perpendicular to the pivot shaft 11, and is attached to the tip threaded portion of the piston rod 16 protruding from the tip surface of the cylinder 15 for direct hook operation. The round shaft-shaped base end 19 with a screw hole of the square ball-shaped base shaft 18 of the hook 17 that is slid into the square hole 13 at the front end of the hole 12 is screwed, and the spring bearing ring 22 and the hook are inserted into the mounting hole 12. A helical spring 23 is placed between the front end surface of the linear motion cylinder 15, and a spring bearing ring 22 is inserted between the circular hole portion of the mounting hole 12 and the front end square hole portion 13.
When the hook 17 is moved back by the retracting action of the hook direct-acting cylinder 15, the base shaft 18 of the hook is pressed into the mounting hole 12 and the front square hole 1 of the hook 17 is moved back.
3, the stepped portion 20 between the square shaft portion of the hook base shaft 18 and the round shaft-like basic weave portion 19 collides with the spring bearing ring 22, causing it to retreat, compressing the helical spring 23, and closing the hook linear motion cylinder 15. Due to the non-operation, the hook 17 moves forward due to the reaction force of the helical spring 23, and the spring receiver ring 22 moves to the step 24 of the mounting hole.
