噴出時の騒音も大きくなるというような問題を有する。Conventional Structure and Problems Conventionally, when a fluid, particularly compressed air, is ejected from a nozzle and the air is directly blown onto the object to force-feed the object, a nozzle as shown in FIG. 1 is used. A is a nozzle, b is a spout, C is an object to be transferred, and d is a passage. In this device, air passes through the passage d and is ejected from the ejection port in the direction of A-A' in the figure.
collides with object C. Generally, the passage d and the jet nozzle have a circular cross section. However, with this method, the ejected air causes a diffusion phenomenon, and instead of colliding with the object properly, it blows around the object, making it impossible to transport the object as intended. There is a problem. Furthermore, if this nozzle were to be used to transfer an object for the intended purpose, the pressure of the ejected air would be increased, which would unnecessarily increase the amount of compressed air consumed and also increase the noise generated when ejecting. I have a problem like this.

。The main body of the invention is circular and has a cross-section of a polygonal cone at the tip, an inner nozzle having a passage through which fluid passes and a spout at its center, and a cone circumscribing the corners of the polygonal cone of the inner nozzle. an outer nozzle which has a tip hole and a hole slightly larger than the inner nozzle body and holds the inner nozzle in this hole, a passage located in the center of the inner nozzle, and a passage formed between the inner nozzle and the outer nozzle. It consists of a fluid supply source that independently supplies fluid to the gap and controls the supply pressure and supply amount.The fluid is supplied to the gap between the inner nozzle and the outer nozzle, and the hole in the inner nozzle is opened to the atmosphere. The supplied fluid passes through the gap between the inner and outer nozzles, is constricted at the tip, and is ejected at a rapid flow rate. Since the spout is located on the same end face as the spout of the inner nozzle, a Venturi phenomenon occurs near the spout of the inner nozzle, and the fluid in the inner nozzle passage is also drawn out in the fluid jetting direction, reducing the jetting flow rate. is larger than the amount of fluid supplied. Furthermore, since both the inner and outer nozzles are narrowed near the jet, the jet has a focal point, and if an object is placed at this focal point, the object can be transported accurately, which is a unique effect.

る。DESCRIPTION OF EMBODIMENTS Examples of the present invention will be described below with reference to FIGS. 2 and 3. 1 is an outer nozzle having a conical hole 2 at its tip. Reference numeral 3 designates an inner nozzle, the tip 3 of which is in the form of a polygonal pyramid, the corner of which is in contact with the conical hole 2 of the outer nozzle, and the cross section of the main body is circular. Moreover, the inner nozzle 3 has an air passage 6 at the center, and a jet outlet 6 is provided at the end thereof. 7 is a circular hole provided in the outer nozzle, which is slightly larger than the main body of the inner nozzle 3. Therefore, a gap 8 is created between the main body of the inner nozzle 30 and the hole T of the outer nozzle 1. 9 is a holding part of the inner nozzle 3;
It is formed on the outer nozzle 1 and is held by press-fitting the inner nozzle 3. 1o is an air supply port (1) that supplies air to the gap 8. 11 is the air supply port (2), and the inner nozzle 3
Air is supplied to the air passage 5 of. Since the pyramidal part 4 at the tip of the inner nozzle 3 and the conical part 2 at the tip of the outer nozzle 1 are a polygonal pyramid and a circumscribed circle, a gap 12 is formed between the sides of the polygonal pyramid 4 and the circumscribed circle.

以上の様な構成で、空気供給口１Ｑに圧縮空気を供給す
ると、空気は図中Ｂ−Ｂ’方向に流れ、先端部２で絞ら

から、さらに流路断面積は狭められており、供給された
空気は高速流となって噴出する。大気中に噴出された高
速空気は、静止状態の空気を巻き込みなからＣ−Ｃ’方
向へ流れる。With the above configuration, when compressed air is supplied to the air supply port 1Q, the air flows in the direction BB' in the figure and is accelerated because it is constricted at the tip 2. Furthermore, due to the above-described structure, the cross-sectional area of the flow path is further narrowed at the tip, and the supplied air is ejected as a high-speed flow. The high-speed air ejected into the atmosphere draws in stationary air and flows in the CC' direction.

特に空気供給口１１が大気に開放されている時、噴出口

端部４が各々の多角錐。In particular, when the air supply port 11 is open to the atmosphere, the air pressure near the jet port 6 decreases, drawing out the air in the passage and causing the C-C
In addition to the amount of supplied air, the air in the flow path 6 also flows in the ' direction. Also, the outer nozzle 1. The tip 2 and the tip 4 of the inner nozzle 3 are polygonal pyramids.

円錐形状であるから、噴出した高速空気は、焦点をもっ
ている。焦点の位置は円錐および角錐の頂角によって決
定する。この焦点の位置に移送すべき物体を位置させる
ことで、噴出した高速空気を適確に物体と衝突させるこ
とが可能となり、物体は高速で所期の位置へ移動する。Because of its conical shape, the ejected high-speed air has a focal point. The position of the focal point is determined by the apex angle of the cone and pyramid. By locating the object to be transported at this focal point, it becomes possible to cause the ejected high-speed air to collide with the object accurately, and the object moves to the desired position at high speed.

さらて一般的には移動中の物体は、メカストッパー等で
停止させるが、移動速度が速い場合、ストッパーに衝突
した時、反発力によって物体は進行方向とは逆の方向へ
押し戻されようとするが、物体移送後一度圧縮空気の供

することで、反発力による押し戻しは防げる。なお本実
施例において使用流体は空気としたが、他の流に良い、
又内ノズル３の先端を多角錐４、外ノズル１の先端２を
円錐としたが、加工可能であれば、この逆でも良いこと
は言うまでもない。Furthermore, moving objects are generally stopped by mechanical stoppers, etc., but if the moving speed is high, when the object collides with the stopper, the repulsive force tends to push the object back in the opposite direction to the direction in which it is moving. However, by interrupting the supply of compressed air once after transferring the object, and then immediately supplying compressed air again for a short period of time, pushing back due to repulsive force can be prevented. In this example, air was used as the fluid, but other fluids may be used.
Further, although the tip of the inner nozzle 3 is a polygonal pyramid 4 and the tip 2 of the outer nozzle 1 is a cone, it goes without saying that the reverse may be used if processing is possible.

発明の効果 以上の様に本発明によれば （１）　　ベンチュリー効果により、供給流体量以上の
噴出流量が得られ、消費流体量が少ない。Effects of the Invention As described above, according to the present invention, (1) Due to the Venturi effect, an ejection flow rate greater than the amount of supplied fluid can be obtained, and the amount of consumed fluid is small.

（２）噴出流体が焦点をもっている為、適確に流体が移
送すべき物体と衝突し、高速、高効率で物体の移送が可
能である。(2) Since the ejected fluid has a focus, the fluid collides with the object to be transferred accurately, making it possible to transfer the object at high speed and with high efficiency.

ある。There are specific effects such as, and the practical effects are like dogs.
