具変換位置に割出しする構造のものがある。 In a magazine device that stores tools, an endless chain is hung between a driving sprocket and a driven sprocket provided on the magazine body, and a plurality of tool gripping claws are connected to this chain at predetermined intervals, and the gripping claws are used to maintain posture. There is a structure in which a guide roller for the tool is pivotally supported, and a required tool gripping claw is indexed to a tool changing position by an indexing motor.

チエーンのテンシヨンの調整とガイド部材の調整
とを、それぞれ別々に行つており、調整操作が面
倒であつた。 In this conventional structure, the tension of the chain is adjusted by moving the driven sprocket. However, when the tension of the chain is adjusted, the position of the posture-maintaining guide roller provided on the gripping claw is displaced, so naturally the guide member that the guide roller comes into contact with must also be adjusted. Therefore, in the past, the tension of the chain and the guide member were adjusted separately, making the adjustment operations cumbersome.

ンに調整される。 The endless chain 11 must have its tension properly adjusted. in general,
As the chain 11 is used, it tends to stretch and sag. Therefore, in this case, the support shaft 4 of the driving sprocket 2 and the support shaft 10 of the driven sprocket 8
The appropriate tension can be adjusted by increasing the distance between the shafts.

る。 Therefore, in the present invention, when adjusting the tension of the chain 11, the clamp bolts 17 and 2 are
1, and operate the adjusting screw 23 to move the adjusting block 9 to the left in FIG. As the adjustment block 9 moves to the left, the driven sprocket 8 also moves together with the adjustment block 9 via the support shaft 10, and the tension of the chain 11 is adjusted. By adjusting the tension of the chain 11, the gripping claws 12
is also displaced, and the positions of guide rollers 13 and 14 that are pivotally supported by gripping claws 12 are also displaced.
Since the movable guide members 5 and 16 are integrated with the adjustment block 9, the positions of the movable guide members 15 and 16 are adjusted at the same time as the tension adjustment of the chain 11, and the movable guide members 15 and 16 are always positioned in correspondence with the guide rollers 13 and 14. After adjusting the tension of the chain 11 in this manner, the clamp bolts 17 and 21 are tightened to complete the tension adjustment work of the chain 11.
