An annular groove 11d. is formed on the outer peripheral surface of the nozzle body l1 so that air can be supplied and discharged to the entire outer peripheral surface of the nozzle body l1. 11d is formed.
上記ノズル本体l1の外周面には、各エアー給排日1l
b.llcに対応してゴム製チューブ12を気密に嵌着
する。On the outer circumferential surface of the nozzle body l1, there is a
b. The rubber tube 12 is hermetically fitted in correspondence with the llc.
上記ノズル本体IKの基部lieにはロックナット13
をねじ止めして、該ロックナットI3のテーパ面13a
と基部lieのテーパ面Iffとでゴム製チューブl2
の上端部12aを挾み込み、チューブl2の抜け止め及
び気密を保持する。A lock nut 13 is attached to the base lie of the nozzle main body IK.
and tighten the tapered surface 13a of the lock nut I3.
and the tapered surface Iff of the base lie and the rubber tube l2
The upper end 12a of the tube 12 is inserted to prevent the tube 12 from coming off and keep it airtight.

金具I4をねじ止めして、該先端金具14のテーバ面1
4aと先端11gのテーバ面11hとでゴム製チューブ
I2の下端11 2bを挾み込み、チューブI2の抜け
止め及び気密を保持する。A cone-shaped tip fitting I4 is screwed to the tip 11g of the nozzle main body 1l, and the tapered surface 1 of the tip fitting 14 is screwed.
4a and the tapered surface 11h of the tip 11g sandwich the lower end 112b of the rubber tube I2 to prevent the tube I2 from coming off and maintain airtightness.
この先端金具l4は、ねじ部14bでノズル本体11の
エアー通路11aの下部11iを気密に閉塞すると共に
、ノズル本体l4をワークlOの穴10aに挿入すると
きのガイドとなる。This tip fitting l4 airtightly closes the lower part 11i of the air passage 11a of the nozzle body 11 with the threaded portion 14b, and serves as a guide when inserting the nozzle body l4 into the hole 10a of the work lO.
上記ノズル本体11のエアー通路11aの上郎11jは
、電磁切換弁を介してエアー給徘源に接続されている。The upper end 11j of the air passage 11a of the nozzle body 11 is connected to an air supply source via an electromagnetic switching valve.
上記のような構成であれば、ワークlOの穴lOaの上
方にノズル本体11を移動させ、ノズル本体11を下降
させて先端金具l4からワークlOの穴10aに挿入す
る。With the above configuration, the nozzle main body 11 is moved above the hole lOa of the work lO, the nozzle main body 11 is lowered, and the nozzle main body 11 is inserted into the hole 10a of the work lO from the tip fitting l4.
ついで、エアー給排源からノズル本体11のエアー通路
11aにエアーを供給すると、エアーはエアー給排日1
lb.11cからノズル本体1lの外周面側に吹き出さ

てゆき、ワーク10の穴10aの内周面に接触して、ワ
ーク10を保持する。この状態で、ノズル本体1lを上
昇させ、移動させてワーク10を所定位置に搬送する。Next, when air is supplied from the air supply/discharge source to the air passage 11a of the nozzle body 11, the air is supplied on air supply/discharge day 1.
lb. 11c to the outer peripheral surface of the nozzle body 1l, the rubber tube 12 is expanded outward by air pressure, comes into contact with the inner peripheral surface of the hole 10a of the workpiece 10, and holds the workpiece 10. In this state, the nozzle body 1l is raised and moved to convey the workpiece 10 to a predetermined position.
そして、ノズル本体l1を下降させ、エアー給排源によ
り、ノズル本体1lのエアー通路11aからエアーを排
出すると、ゴム製チューブl2がその弾力で内方へ萎み
、ワーク10の穴10aの内周面に接触しなくなり、ワ
ークIOの保持を解除する。Then, when the nozzle body l1 is lowered and air is discharged from the air passage 11a of the nozzle body 1l by the air supply/discharge source, the rubber tube l2 shrinks inward due to its elasticity, and the inner periphery of the hole 10a of the workpiece 10 It no longer contacts the surface and releases the hold on the workpiece IO.
このように、ノズル本体l!は、ワークIOの外形より
も小さいので、密着状態で並べ置かれたワークlOでも
簡単に保持できる。In this way, the nozzle body l! is smaller than the outer shape of the workpiece IO, so it can be easily held even when the workpieces IO are placed next to each other in close contact with each other.
換言すれば、従来のチャック式のように、間隔を隔てて
ワークlOを並べる必要がなくなる。In other words, unlike the conventional chuck type, there is no need to line up the workpieces 10 at intervals.
なお、ノズル本体1lを多数設けることにより、多数の
ワーク10を同時に保持・搬送することもできる。Note that by providing a large number of nozzle bodies 1l, a large number of works 10 can be held and transported simultaneously.
また、ワーク10の保持は、膨らんだゴム製チューブl
2で行なうから、ワークlOの穴10aの内周面に傷が
つかず、ワーク10の保持も確実である。In addition, the workpiece 10 is held by a swollen rubber tube l.
2, the inner peripheral surface of the hole 10a of the workpiece 10 is not damaged and the workpiece 10 can be held securely.
