Abstract

PURPOSE:To permit an efficient and accurate cleaning of a rod-like body for removal of oily stains or soiled spots therefrom by a method wherein the rod- like body wet with cleaning liq. is forced into a soft and elastic body through its opening having a smaller diameter than that of the rod-like body and passed therethrough in pressing contact with the peripheral edge thereof. CONSTITUTION:When a rod-like body 1 wet with cleaning liq. is forced into an opening 21 of a soft and elastic body 2, the peripheral edge 26 of the opening thereof is forcibly deformed by the rod-like body 1 and, under its restoring force and the force of a compression ring 22, the peripheral edge 26 is urged against the rod-like body 1. For this reason, as the rod-like body 1 is fed in the direction A, oily stains or soiled spots are strongly scraped off from the rod-like body 1 together with the cleaning liq. by the elastic body 2. This rod cleaning method assures an accurate stain removal, since such stains have already lost the stickiness to the rod-like body 1 by the washing action of the cleaning liq. and, at the same time, the so-called dewatering is carried out. And the removed stains and the cleaning liq. are recovered from a groove 62 to a cleaning liq. recovery container 8 located thereunder.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for cleaning a rod-shaped body to remove oil and dirt adhering to a ground rod or the like.

[Conventional technology]

When it is necessary to remove oil or dirt from a metal rod such as a grounding rod, the conventional method is to wet the rod with cleaning liquid and then manually wipe off the cleaning liquid from each rod one by one. I was going.

[Problem to be solved by the invention]

However, in rod-shaped bodies such as earth rods that are manufactured by cutting a long rod-shaped body to a predetermined length and then sequentially performing a prescribed end treatment, oil adhesion may occur as described above. There was a problem in that the overall production efficiency was reduced because the work of cleaning dirt and grime was inefficient manual work. In addition, when the cleaning solution is manually wiped off one stick at a time, there are significant individual differences in cleaning effectiveness, and there is also the problem that the degree of removal of attached oil and dirt is difficult to stabilize, leading to wide variations in quality. Ta.

The present invention has been made in view of the above problems, and it is possible to efficiently and reliably clean and remove oil and dirt adhering to a rod-shaped body without requiring manual labor, and the degree of removal is stable. The purpose is to provide a method for cleaning oil.

[Means to solve the problem]

The method of cleaning a rod-shaped body according to the present invention includes pushing a rod-shaped body wetted with a cleaning liquid into the opening of a soft elastic body having an opening with a diameter smaller than that of the rod-shaped body, and pressing the peripheral edge of the opening against the rod-shaped body while cleaning the rod-shaped body. It allows the passage of

(Function) According to the method of the present invention, oil and dirt attached to the rod-shaped body are easily peeled off from the rod-shaped body by the cleaning action of the cleaning liquid, and are scraped off together with the cleaning liquid by the soft elastic body. Particularly, since the soft elastic body comes into pressure contact with the rod-shaped body and scrapes off adhering oil and dirt, its scraping action is effectively exhibited. Further, since the rod-shaped body is pushed into and passed through the opening of the soft elastic body, the cleaning operation can be performed in a series of steps.

〔Example〕

FIG. 1 is an explanatory diagram of a rod-shaped body cleaning method according to an embodiment of the present invention. In the figure, l is a rod-shaped body, such as an earth rod having a copper coating formed on the outer surface of an iron core. 2
is a soft elastic body. The rod-shaped body 1 is fed in the direction of arrow A in the figure, and after its surface is wetted with the cleaning liquid 4 flowing down from the nozzle 3, a cleaning and removal process by the soft elastic body 2 is continuously performed.

As the cleaning liquid 4, a polar organic solvent that dissolves the oil adhering to the rod-shaped body 1, such as inexpensive kerosene, can be suitably used, but depending on the type of adhering oil, water, soapy water, or other solvents may be used as the cleaning liquid 4. It is also possible. Further, the nozzle 3 desirably has a flat liquid outlet, and when the cleaning liquid 4 is allowed to flow down onto the rod-shaped body 1 from such a liquid outlet, the surface of the rod-shaped body 1 is reliably wetted with the cleaning liquid 4.

The rod-shaped body 1 wetted with the cleaning liquid 4 is sent to a cleaning and removal process, where the attached oil and dirt are scraped off by the soft elastic body 2 together with the cleaning liquid.

As is clear from FIGS. 2 and 3, the diameter of the opening 21 of the soft elastic body 2 in its natural state is one diameter smaller than the outer diameter d of the rod-shaped body 1. Further, a compression ring 22 in which a coil spring is held in a ring shape is fitted around the opening 21 of the soft elastic body 2, and the force of this compression ring 22 is applied in the direction of reducing the diameter of the opening 21. The soft elastic body 2 shown in the figure is one in which a boss portion 23 forming the opening 21 and an outer edge portion 24 concentric with the boss portion 23 are integrally molded, and the boss portion 23 is easily deformed when pressed with a finger. However, the outer edge portion 24 is made harder. Then, the soft elastic body 2 is fitted into the holder 5 by press-fitting the outer edge portion 24 into the recess 51 of the metal holder 5, and the soft elastic body Press 2 to stop the removal. Further, the inner surface of the boss portion 23 has a tapered surface 24,25 on both sides of the opening 21, the diameter of which gradually decreases as it approaches the opening 21.
In the portion 1, the peripheral edge 26 has a sharp edge-like cross-sectional shape, and the other tapered surface 25 has a steeper slope than the tapered surface 24 on the front side of the opening 21.

Further, the flange 61 of the guide cylinder 6 is formed with a groove 62 that extends vertically in the radial direction. Reference numeral 7 indicates a mounting bolt for the flange 61.

When the rod-shaped body 1 wetted with cleaning liquid is pushed into the opening 21 of the soft elastic body 2 described above, the peripheral edge 26 of the opening 21 of the soft elastic body 2 is pushed by the rod-shaped body 1 as shown in FIG. When deformed, the restoring force at that time and the force of the compression ring 22 cause the peripheral edge 26 to come into pressure contact with the rod-shaped body 1. Therefore, as the rod 1 is fed in the direction of arrow A, the oil and dirt adhering to the rod 1 are strongly scraped off together with the cleaning liquid by the soft elastic body 2. The scraping at this time is performed reliably because it is performed on the attached oil and dirt that are easily peeled off from the rod-shaped body 1 due to the cleaning action of the cleaning liquid, and at the same time, the so-called water-draining action is performed. Almost all of the adhering oil and dirt scraped off the rod-shaped body 1 and the cleaning liquid are guided into the groove 62 and collected in the lower cleaning liquid collection container 8, and the cleaning liquid is recycled and reused. It was found that the rod-shaped body 1 that had passed through the opening 21 of the elastic body 2 had almost completely removed the attached oil and dirt, and was in a relatively dry state.

As in this embodiment, when the boss portion 23 of the soft elastic body 2 is made flexible and is biased in the diametrical direction by the compression ring 22, the peripheral edge 2ε of the opening 21
The cleaning and removal effect of adhering oil is improved because it firmly adheres to the surface. Therefore, although it is desirable to do so, even if the force of the compression ring 22 is not applied to the boss portion 23, the cleaning is relatively high because the peripheral edge 26 of the opening 21 is in pressure contact with the rod-shaped body l. It has been confirmed that removal and drainage effects can be obtained. Therefore, it is not essential to apply the force of the compression ring 22 to the boss portion 23.

As the soft elastic body 2, a molded piece of neoprene rubber, which is used as a mechanical element in sealing materials such as O-rings, can be suitably used. The soft elastic body 2 made of neoprene rubber has excellent abrasion resistance, so it has a long service life, and the frequency of replacement is reduced, which also has the advantage of improving productivity. In addition,
The soft elastic body 2 may be a one-piece body or a divided body (for example, divided into two pieces).

Further, the peripheral edge portion 26 does not necessarily have to be sharp like a curved shape, but may have a curved cross-sectional shape such as an arc shape.

〔Effect of the invention〕

As described above, according to the method of the present invention, it is possible to efficiently and reliably wash and remove adhering oil and dirt from rod-shaped bodies without using human hands. It becomes stable and the quality becomes stable. Further, by pushing the rod-like bodies one after another into the opening of the soft elastic body and allowing them to pass through, it becomes possible to wash a large number of rod-like bodies continuously. Therefore, in the case of rod-shaped bodies such as earth rods in which the pre-processing process leading to the cleaning process is performed as a continuous process, the overall production efficiency is significantly improved compared to the conventional method.
