Description

Technical Field

[0001] The present invention relates to an automatic supply device for a spatter adhesion preventive agent of the dunking type.

Background Art

[0002] Conventionally, in arc welding such as TIG welding, MAG welding, and CO2 welding, there has been a problem that spatter generated during welding adheres to the inner surface of the torch nozzle, disturbing the flow of shielding gas and deteriorating the welding quality. To address this problem, it has been effective to apply a spatter adhesion preventive agent to the torch nozzle, and an operation has been performed where an operator manually applies a liquid or grease-like spatter adhesion preventive agent to the torch nozzle. Also, a method has been proposed in which a mist-like spatter adhesion preventive agent is mixed with the air for blowing and the spatter adhesion preventive agent is applied to the inner surface of the nozzle.

[0003] However, the operation of manually applying the spatter adhesion preventive agent to the nozzle is time-consuming and laborious, and there has been a problem of reducing the efficiency of the welding operation. Also, welding operations are often performed in a dim and narrow work site, and the space for installing the container of the spatter adhesion preventive agent and the space for performing the application work are restricted. Therefore, it has been necessary to move to another location to perform the operation of applying the spatter adhesion preventive agent to the nozzle, and there has also been a problem of further deteriorating the work efficiency.

[0004] Therefore, as in Patent Document 1, there is a system for dunking the torch nozzle at a predetermined position. In Patent Document 1, a method of gradually lowering the torch nozzle as the spatter adhesion preventive agent decreases and a method of automatically supplying the spatter adhesion preventive agent to a predetermined position of the container using a vacuum balance are shown.

Patent Document 1

[0006] However, the method of gradually lowering the torch nozzle required specialized parts, making it difficult to transport to the site and cumbersome due to its size. Furthermore, the method utilizing vacuum balancing had problems: the surface tension of the liquid hindered airflow, preventing the negative pressure in the bottle from being released and thus hindering the smooth supply of the spatter-preventing agent. [Means for solving the problem]

[0007] To solve the above problems, the present invention provides two holes at the bottom of the bottle, one as an air inlet and the other as a spatter adhesion prevention agent outlet, thereby enabling a smooth supply of the spatter adhesion prevention agent.

[0008] The bottle, the tap, and the spatter-preventing agent application container (hereinafter referred to as the application container) are installed horizontally apart. The inlet for the air intake and the outlet for the spatter-preventing agent outflow are provided on the application container, while the outlet for the air intake and the inlet for the spatter-preventing agent outflow are provided on the tap. The tap is detachable from the mounting base and is installed so as to communicate with two holes provided on the mounting base. The two holes on the mounting base extend vertically and then communicate with a horizontal flow path connected to the application container.

[0009] The lateral channel of the spatter adhesion prevention agent outlet is perpendicularly connected to the holes extending from the mounting base, while the lateral channel of the air inlet is connected at a rightward incline from the mounting base to the coating container. The inlet of the air inlet and the outlet of the spatter adhesion prevention agent outlet on the coating container can function even if they are at the same height.

[0010] However, it takes some time for it to start working, and there is a large variation in the timing, so it is preferable to set the inlet of the air intake hole higher and create a height difference between the two holes. By creating a height difference, the roles of one hole as an air intake hole and the other as a spatter adhesion prevention agent outlet hole become clearer, and the responsiveness of the operation improves. Furthermore, by tilting the bypass of the air intake hole diagonally to the right from the mounting base to the coating container, its role as an air intake hole becomes clearer, and the responsiveness of the operation improves even further. [Effects of the Invention]

[0011] The automatic spatter adhesion inhibitor supply device of the present invention is easy to carry to welding sites. This technology makes it possible to quickly and easily apply a spatter-preventing agent to the torch nozzle at welding sites, and ensures a consistent supply of the spatter-preventing agent to the application container when dipping the torch nozzle.

[Figure 7] This diagram shows the positioning marks used when attaching the cock to the mounting base. [Modes for carrying out the invention]

[0013] The embodiments of the present invention will be described below with reference to the drawings.

[0014] As shown in Fig. 1, the present invention is composed of a bottle 1 for storing a sputter adhesion preventive agent, an openable and closable cock 2 which is detachable from the bottle 1 and provided with two holes 21 and 22, an installation base 3 for mounting the cock 2, and two flow paths 41 and 42 connecting from the installation base 3 to a coating container 4.

[0015] As shown in Fig. 5, a sputter adhesion preventive agent is put into the bottle 1, and a detachable cock 2 is mounted. As shown in Figs. 2 and 6, the cock 2 is provided with two holes, an air inlet hole 21 and a sputter adhesion preventive agent outlet hole 22.

[0016] As shown in Fig. 6, with the cock 2 closed, the bottle 1 is turned upside down and the cock 2 is mounted on the installation base 3. As shown in Fig. 5, the installation base 3 is also provided with two holes 31 and 32. The cock 2 is mounted on the installation base 3 such that the air inlet hole 21 and the sputter adhesion preventive agent outlet hole 22 communicate with the two holes 31 and 32. Further, as shown in Fig. 7, marks composed of vertical lines are provided on the outer surfaces of the cock 2 and the installation base 3. By aligning the vertical lines of the cock 2 and the installation base 3, the cock 2 and the installation base 3 can be easily mounted without visually checking the positions of the holes. Although the vertical lines are based on matching the arrows, they may be simple straight lines or other marks. Moreover, although the vertical lines shown in the drawings are printed, they may be formed three-dimensionally such as concave or convex.

[0017] Since O-rings 5 and 5 are provided on the cock 2 interposed between the bottle 1 and the installation base 3, the sealing property is high and there is no risk of liquid leakage during and after mounting.

[0018] [[ID=|16]]As shown in Figs. 1 and 2, the two holes 31 and 32 of the installation base 3 extend vertically and then communicate with horizontal flow paths 41 and 42 which are continuous from an air inlet 41a provided in the coating container 4 and an outlet 42a for the sputter adhesion preventive agent outflow hole.

[0019] The horizontal flow path 42 for sputter adhesion preventive agent outflow intersects perpendicularly with the hole 32 continuous from the installation base 3, while the horizontal flow path 41 for air inflow is connected with an inclination to the right and downward obliquely from the installation base 3 to the coating container 4.

[0020] Also, as shown in FIG. 1, the inlet 41a for the air inlet hole provided in the coating container 4 is positioned higher than the outlet 42a for the sputter adhesion preventive agent outflow hole. By creating a height difference or inclination, the roles of one being the air inlet hole and the other being the sputter adhesion preventive agent outflow hole are clearly defined, and the responsiveness of the operation is improved.

Example

[0021] When the cock 2 is opened, the sputter adhesion preventive agent instantaneously flows down from the bottle 1 through both holes 21 and 22 and flows out to the coating container 4 through the horizontal flow paths 41 and 42.

[0022] Immediately after that, the outflow of the sputter adhesion preventive agent from the air inlet hole 21 stops, and instead, air continuously flows into the bottle 1. Then, the sputter adhesion preventive agent flows down only from the sputter adhesion preventive agent outflow hole 22.

[0023] The sputter adhesion preventive agent continues to accumulate in the coating container 4. When it reaches the inlet 41a for air inflow, the air inflow stops, and immediately after that, the sputter adhesion preventive agent is sucked up into the bottle 1 from the inlet 41a for air inflow.

[0024] At this time, the air pressure in the bottle 1, the sputter adhesion preventive agent in the bottle 1, and the sum of the liquid pressures in the two horizontal flow paths 41 and 42 are in a state of equilibrium with the atmospheric pressure. Therefore, the flow-down of the sputter adhesion preventive agent from the sputter adhesion preventive agent outflow hole 22 stops.

[0025] Therefore, when the torch nozzle is immersed in this spatter adhesion inhibitor (dip dipping), the amount of spatter adhesion inhibitor decreases. However, the liquid level of the spatter adhesion inhibitor in the coating container 4 remains at the same level as the air inlet 41a. As the spatter adhesion inhibitor decreases, the liquid level drops, exposing the inlet 41a. Air flows into the bottle 1 from the inlet 41a, and the spatter adhesion inhibitor in the bottle 1 flows into the coating container 4 from the outlet 42a through the spatter adhesion inhibitor outlet hole 22, raising the liquid level and blocking the inlet 41a. This stops the inflow of the spatter adhesion inhibitor, and a certain amount of spatter adhesion inhibitor is stored in the coating container 4.

[0026] The remaining amount of spatter-preventing agent in bottle 1 can be visually checked, but this can reduce the worker's concentration and decrease work efficiency. Therefore, as shown in Figure 1, a liquid detection sensor 7 can also be attached to the outside of bottle 1.

[0027] The mounting base 3 and the coating container 4 are integrally molded from a rigid synthetic resin. Alternatively, they may be made by machining a rectangular metal block and assembling it into a single unit. [Explanation of Symbols]
