う問題がある。BACKGROUND OF THE INVENTION Adhesive application is transitioning from manual application with brushes or rollers to automatic mechanical application. For application over a large area, it is possible to use a fan-pattern sprayer that ejects a fan-shaped mist, and it has been found that an airless sprayer is better. However, the commonly used airless fan pattern spray nozzle has a pilot hole in the nozzle tip that is open at the rear and has a dome-shaped end, and the front part has a V-shaped cross-section with both sides flat. A split groove is cut to intersect at right angles to the axis of the pilot hole, and the depth of the intersection of the slot groove with the pilot hole substantially coincides with the boundary between the straight part and the terminal part of the pilot hole, A lip-shaped nozzle opening is created by the intersection of these slotted grooves and the pilot hole, and if a conventional fan pattern spray nozzle like this is used, the disadvantage is that the atomized mist will be scattered over a wide area. However, when applying high viscosity adhesives, there is a disadvantage that large tail marks occur on both ends.This is particularly good when the distance to the object to be applied is relatively far, but when applying from a short distance. The coating film is extremely uneven due to the tail marks, so when applying adhesive with emphasis on the periphery of a wide area as shown in Figures 6 and 7, the adhesive may come off the periphery of the object A. As a result, the mist and the tail mark part are scattered and transported to the outside, reducing the adhesive application efficiency and
This has the disadvantage of contaminating the environment, and in order to prevent this, if the spray position is moved inward for coating, there is a problem that the coating will be incomplete on the edges of the object to be coated.

るものである。(Purpose) This invention provides a fan pattern that does not generate tail marks at both ends, even when spraying a highly viscous liquid such as adhesive from a very short distance, and one end that is uniform. The object of the present invention is to obtain a spray-type coating nozzle that can obtain a fan pattern with a film thickness that hardly generates scattered mist.

た。(Structure) As a result of research on the shape of the lip-shaped nozzle opening in a fan pattern spray nozzle, the inventor of the present invention found that the shape of the slotted groove that intersects with the end of the pilot hole is such that the main part of the groove has a relatively wide angle. The nozzle opening is formed into an almost inverted human-shaped or Y-shaped cross section with a sharp and narrow angle at the deep end, and the nozzle opening is lip-shaped with a locally bulged center and narrow and sharply extending ends. It has been discovered that the occurrence of tail marks can be reliably suppressed when a highly viscous liquid is applied and sprayed onto the fan pattern.

られることを発見した。 In addition, the slotted grooves are not perpendicular to the axis of the pilot hole but are formed to intersect with each other in a moderately oblique manner, and the shallower the depth of the intersection, the more it is approximately at the boundary between the straight part and the terminal part of the pilot hole. In addition, the deeper part intersects the straight part of the pilot hole relatively deeply, and the intersection of these slotted grooves and the pilot hole creates an almost lip-shaped nozzle with both ends extending sharply and one bent backwards. It has been discovered that when the mouth is opened diagonally forward, a fan pattern can be obtained at one end in which almost no scattered mist is generated.

いることを特徴とするものである。 The coating nozzle of the present invention has been developed based on the above findings, and is a coating nozzle that sprays liquid in a fan pattern, and has a nozzle tip having a rounded cone-shaped or dome-shaped end portion in a rearward open state. A pilot hole is provided in the front part of the nozzle tip body, and both sides are arcuate or dogleg-shaped, with the main part of the groove having a relatively wide angle and the deep part having a sharp narrow angle. A slotted groove with a letter-shaped or Y-shaped cross section is formed, the slotted groove is carved obliquely intersecting the axis of the pilot hole, and the depth of the intersection of the slotted groove with the pilot hole is The shallower side almost coincides with the boundary between the straight part of the pilot hole and the end, and the deeper one deeply intersects with the straight part of the pilot hole, and due to the intersection of these slots and the pilot hole, both ends are It is characterized by a nearly lip-shaped nozzle opening that extends sharply and bends one end backwards, and is opened diagonally forward.

口５が斜め前向きに開設される。 As shown in the figure, the nozzle tip body 1 is provided with an elliptical cone-shaped lower hole 3 whose front end portion 2 is formed into an elliptical dome shape.
A slotted groove 4 is carved in the front part of the front part, and has a substantially inverted human-shaped or Y-shaped cross section with both sides convex inwardly in the shape of an arc (can also be in a dogleg shape). 4 obliquely intersects the pilot hole 3, and in the illustrated embodiment, the angle is 10° to the perpendicular to the axis of the pilot hole 3.
It is 15.5°. Moreover, regarding the degree of intersection,
The shallower part of the intersection almost coincides with the boundary between the terminal part 2 and the straight part of the pilot hole 3, and the deeper part of the intersection deeply intersects the straight part of the pilot hole 3. By intersecting with the slotted groove 4, a substantially lip-shaped nozzle opening 5 with both ends extending sharply and one bent backward is opened diagonally forward.

No tail marks are generated at either end of the fan pattern, and at the end of the fan pattern on the shallow side of the slotted groove 4, the edge of the coating film is formed without scattering of mist. A coating film with a uniform thickness can be obtained.

する。 The embodiments shown in FIGS. 4 and 5 are configured to form an air curtain around the airless fan pattern, which prevents fine mist from scattering and also suppresses tail marks.
That is, the nozzle tip body 1 is press-fitted into the tip of the support body 6, and the front end of the support body 6 is formed into an obliquely protruding horseshoe shape in a state corresponding to the inclination of the nozzle port 5 of the nozzle tip body 1. An air passage 7 is provided in the large diameter portion. On the outer periphery of the support 6,
An air nozzle body 8 is fitted, and a horseshoe-shaped nozzle opening 9 is formed diagonally forward at the front end of the air nozzle body 8 so as to correspond to the front end of the support body 6, and the front end of the support body 6 and the air nozzle A horseshoe-shaped annular air nozzle is formed between the front end of the body 8 and the front end of the body 8.
Air of several kg/cm 2 or less is supplied from the rear air passage 7 to form an air curtain surrounding the fan pattern spray diagonally forward from the air nozzle opening.

It may be pyramidal or conical. However, it was found that a rectangular pyramid with rounded corners, an isosceles triangular pyramid with rounded corners, and an elliptical cone caused less mist to scatter. In the case of a pyramid, the end portion 2 needs to have rounded edges. In addition, the surface to be coated during spraying is not installed perpendicularly to the nozzle axis, and the slotted groove 4
