JPS60122074A - Method and device for coating high-viscosity fluid such as sealer - Google Patents

Abstract

PURPOSE:To obtain a good-looking and efficient coating by carrying out the pressing and fairing after coating a high-viscosity fluid such as a sealer with use of compressed air on a noncontact basis. CONSTITUTION:The step part 11a of a valve 11 and the shaft end 12a of a valve 12 are detained by a lever 13 by pulling the lever 13 supported by a body part 6 in the direction shown by the arrow, and a sealer supply passage 7 and a compressed air supply passage 8 are opened. In this case, a clearance is formed between the valve shaft end 12a and the coupling part of the lever 13. Accordingly, when the lever 13 is pulled, the valve 11 is firstly opened to discharge a sealer from a nozzle 4a, and then the valve 12 is opened with some time lag to spout compressed air from a nozzle 5a. When the sealer is coated along the terminal of the lapped part of plate materials in the direction shown by the arrow E by using such a coating device, an uniform coating with good adhesion can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to 11) a method for applying a highly viscous liquid such as a sealer to the joint parts of plate materials such as automobile bodies for waterproofing, rust prevention, and dust prevention; This is related to Ili-b.

In an automobile or the like, for example, as shown in FIG. 1, a sear 92 is applied along the end of the folded portion 1a of the plate material 1 and the joint portion of the thin plate material. In this case, the sealer is generally applied using a gun with the sealer discharging nozzle right. The surface is not smooth and has wrinkles!1, and the appearance is not good.Therefore, after applying Sea 9, I use a brush or spatula to press and shape the Sea 9, but it is time consuming. In addition, since it is based on the human sense, there are problems such as uneven shaping, and the scene may be placed in unnecessary areas during the work. 9 after high viscosity fluid coating YIJ such as
1′! The purpose of this work is to provide a Puno method that allows shapes to be made uniformly without using any printing methods, and to provide an apparatus suitable for practicing this method. Water light to achieve the purpose is high viscosity 1 of the scene etc.
It is characterized by the fact that the pushing angle after application of the recirculating fluid (hereinafter referred to as "scene") is performed in a non-contact manner using IJ compressed air.

In other words, in the hot light method, a sheet is applied to the end of the center part of the plate material using a sealer discharge nozzle, and then a compressed air jet nozzle or the like is applied from the side of the coated sheet directly. j1 Blow out the compressed air. As a result, the scene is pressed by the C air 1 king and tightly packed into the board material, and the wrinkles on the surface are also crushed to make it a smooth surface.J,
Due to its flexibility, the sheet may sag in the shape of .eta. after coating, but since it is pressed with compressed air immediately after coating, deformation is prevented.

When applying the sheen in a linear manner along the end of the overlapping part of the plate materials, move the sheen discharge nozzle to the end of the sheet and move the compressed air jetting means to follow the nozzle. Press and shape the scene.

Figure 2 shows a sealer coating device suitable for such work; 6
This shows that.

Between stations there is a scene supply pipe 4 and a compressed air supply vibe 5
These vibrators 4.5 are connected so that their central parts overlap. The tip of the vibrator 4 forms a scene discharge nozzle 4a, and the tip of the vibrator F) forms a compressed air blowout nozzle 5a, d3. In the case of wood addition, the compressed air blowing direction is approximately 45 degrees to the scene blowing direction. There is a slanted tightener "C". 6 is a sealer supply port "I8" inside the body part C1.
7 and compressed air supply passage 8 are circular. The base end of the scene supply pipe 4 is connected to one opening of the scene supply passage 7, and the base end of the scene supply pipe 4 is connected to one opening of the compressed air supply passage 8. The base ends of the vibrators 5 are connected to each other.

Between the other side of the scene supply passage 7, there is a sealer supply source 9 connected to the scene supply source, and between the other side of the compressed air supply passage 8, there is a 11 cotton 3) A compressed air supply bowl 10 is connected.

ILL- is connected to the scene supply passage 7 and the compressed air supply passage 8.
The opening and closing valves 11 and 12 are installed ().

On the other hand, one end of the lever 13 is rotatably supported on the body part 6. The 12 valve shaft ends 12a are engaged with the 1 flange 1ζ3, and the scene supply passage 7, d3, J: and 1, and the air supply passage 8 are opened.

Note that a gap is formed between the shaft end 12a of the valve 12 and the engaging part of the lever 13, so that when the lever 1:3 is pulled, the valve 11 of the scene supply passage 7 is first heard and C The scene is discharged from the nozzle 4a, and with expert timing, the valve 12 of the compressed air supply passage 8 is pressed, and compressed air is spouted from the nozzle 5a.

Using the above sheen applicator, we applied the sealer to the sheet material 1 by moving in the three directions of the arrows l along the ends of the sheet material 1. As a result, the adhesion of the sheen to the sheet material was good, and the sheen surface was The coating is smooth, wrinkle-free, and has a uniform width without losing its shape. The implementation conditions were as follows.

Δ) It was confirmed that the range of 110° to 120° is preferable.

As explained below, 1. :J, :UniAccording to the present invention, when applying sheep to the wheels and joints of a board, it is applied to the core 15 after applying the sealer. :CQ)-J
By blowing compressed air from both sides, the sheep's sealing bamboo sticks to the board, and there are no wrinkles on the sealer surface.
The method of applying sheep according to the present invention is to perform a sheep coating that does not cause the shape of the piled seaweed to be distorted. ``The first thing is the workability, and the fourth thing is the implementation.''
