[0002]

2. Description of the Related Art In order to improve the durability of architectural wood such as pillars, beams and foundation materials, a large number of woods are accommodated in a pressure cooker and an antiseptic and insect repellent is supplied. It has been practiced to keep the raised state for a long time and to penetrate the surface of wood with an antiseptic / insecticide. In such a treatment, in order to increase the efficiency of the treatment, the pressure cooker is made extremely large so that a large number of lumbers of several meters in length can be accommodated. It is made correspondingly large.

[0003]

The above-mentioned pressure cooker and auxiliary equipment are large in size, so that a large installation space is required, the equipment cost is high, and furthermore, it is not suitable for processing a small number of materials to be processed. In addition, the processing requires a long time. The present invention solves such a problem. Even if a small number of architectural timbers or a large number of architectural timbers are used, a relatively small device can be used to conveniently, inexpensively, and quickly control the insects and insects. An object of the present invention is to provide a ring-shaped curtain liquid spray coating device capable of penetrating a termiticide.

[0004]

According to the present invention, in order to achieve the above object, an annular liquid chamber to which a liquid agent of an appropriate pressure is externally supplied is formed, and a circumferential portion of an inner peripheral wall of the liquid chamber is formed. A liquid passage slit for ejecting the liquid agent in the annular liquid chamber in a curtain shape toward the center of the liquid chamber is formed in the entire periphery, and the annular liquid chamber is formed in an anteroposterior position with respect to the annular liquid chamber. A structure is provided in which conveyance means for the material to be processed is disposed so as to pass through the center inner hole of the liquid chamber.

[0005] The slit for the liquid passage injects the liquid agent in the form of a curtain, and sprays the liquid agent on the surface of the material to be processed passing through the central inner hole of the annular liquid chamber. At this time, since the liquid material is sprayed from the entire circumference of the annular liquid chamber toward the center of the annular liquid chamber, even if the material to be processed is moved quickly, the entire peripheral surface of the material to be processed directly applies the liquid material. It can be applied effectively without being spotted.

The above-mentioned invention is specifically as follows. That is, a casing surrounding the periphery of the ring-shaped curtain liquid spraying device is provided, and on a conveying means for conveying the material to be processed at positions before and after the ring-shaped liquid chamber in the casing,

[0007] In this case, the coating section becomes compact, and the liquid agent ejected from the liquid passage slit does not scatter outside the casing, but is applied to the surface of the material to be processed with an appropriate thickness. Become.

The slit for the liquid passage is arranged so as to be inclined at an advancing angle with respect to the conveying direction of the material to be processed, so that the curtain liquid having a conical wall shape is sprayed. According to this, it is possible to suppress the rebound of the liquid material hitting the processing target portion from diminishing the force of the liquid material ejected from the liquid passage slit.

[0009] The liquid agent ejected from the liquid passage slit, which does not adhere to the agent to be treated, is collected, filtered, and supplied again to the annular liquid chamber. In this case, the liquid agent can be efficiently supplied to the annular liquid chamber.

After preparing building wood (shaft members such as pillars and beams with processed joints and joints) w to be processed, and storing a liquid antiseptic and insecticide in the liquid agent tank 25, Activate.

[0023] In the operating state, the supply pump 26 liquid liquid suitable pressure annulus fluid chamber 7 of the injector 9 (range approximately of ^{1kg / cm 2 ~10kg / cm 2} ) in the liquid tank 25
Supply by As shown in FIG. 7, the liquid agent supplied in the annular liquid chamber is supplied to the liquid passage slit (having a width of about 0.01).
(in the range of 0.2 mm to 0.2 mm) 8, and is ejected in the form of a curtain on the center of the annular liquid chamber 7 slightly toward the rear side of the plane including the slit 8 (that is, in the direction forming an advancing angle). Therefore, the curtain-shaped jet liquid has a conical wall surface. At this time, the angle θ of the jet liquid is set in a range of approximately 10 degrees to 20 degrees with respect to the radial direction of the annular liquid chamber 7.

The coating casing 12 and the blocking plates 14a, 1
Reference numeral 4b restricts the liquid ejected from the liquid chamber 7 from scattering outside the coating casing 12, guides the liquid downward, and drops the liquid onto the liquid receiving tray 6. Then, the liquid return passage 28 receives the liquid falling from the liquid outlet 6 a of the liquid receiving tray 6 and circulates the liquid into the liquid tank 25. On the other hand, the electric motor 21 rotates each drive roller 19, and the exhaust port 27 b exhausts the air inside the outer casing 27 to another place via an exhaust fan (not shown).

Under such an operating condition, the material to be treated w is supplied one by one to the upper surface on the right side of the row of drive rollers 19 of the rear drive roller transporting device 17A. When there is a dent such as, for example, it is arranged so as to face sideways or downward. As a result, the material to be processed w is carried into the outer casing 27 by applying the transfer force of the drive roller 19, and then is transferred to the main body 4 of the coating processing unit 1.
It is fed inward through a through hole 12a on the rear side of the coating casing 12 and a through hole c of the blocking plate 14a.

In the main body 4, the material to be processed w is supported by a supporting roller e.
While passing through the central inner hole of the annular liquid chamber 7, the liquid agent ejected from the liquid passage slit 8 during this passage is sprayed around the entire surface of the material to be processed w and is substantially evenly distributed. Thickly adhered. At this time, the liquid material spraying direction is inclined backward by about 10 to 20 degrees with respect to the radial direction of the annular liquid chamber 7, so that the liquid material that collides with the surface of the workpiece w and rebounds subsequently. The force of the liquid ejected from the slit 8 is not diminished, the liquid is continuously and stably ejected, and the excess liquid hangs down without adhering to the material to be processed w. It will fall.

The material w to which the liquid material has been applied in this way is sent out of the main body 4 through the through-hole c of the blocking plate 14b and the through-hole 12b on the front side of the coating casing 4, and is fed to the front drive roller transport device 17B. Is gradually moved to the right side of the upper surface of the 19 rows of drive rollers.

While the material to be processed w is passing through the main body 4, the rubber plate 13 surrounding the through hole c of the blocking plate 14a on the entrance side of the main body 4, as shown in FIG. It adheres to the surface by its own elasticity, and by this rubbing action, dust adhering to the surface of the material to be processed w is wiped off on the right side of the rubber plate 13 and ejected from the liquid passage slit 8 on the left side of the rubber plate 13. As a result, the liquid material which is scattered and scattered is made to flow downward, and the rubber plate 13 surrounding the through hole c of the blocking plate 14b on the outlet side of the main body 4 is also provided on the surface of the workpiece w as shown in FIG. 6B. Due to its own elasticity, it adheres tightly, and by this rubbing action, the liquid material sprayed from the liquid passage slit 8 on the right side of the rubber plate 13 is shut off and flows downward, and extraly adheres to the surface of the workpiece w. Scraped liquid and let it flow down It becomes as.

The material to be processed w is supplied to the front drive roller transport device 17
When the right side of the upper surface of the row of drive rollers 19 of B is reached, the drive roller 19 of the transport device 17B applies a transfer force to the workpiece w, and therefore the front drive roller transport device 1
7B first conveys the workpiece w together with the rear drive roller conveying device 17A, and finally conveys it alone and carries it out of the outer casing 27. The material to be processed w carried out in this way is moved to another place by an appropriate means.

On the other hand, the liquid agent flowing down from the main body 4 is returned to the liquid agent tank 25 via the liquid return passage 28 and filtered as described above. Since the liquid agent thus circulated is reduced by the amount attached to the material to be processed w, it is necessary to replenish the liquid agent tank 25 as needed. As described above, the material to be treated w is sequentially coated with the antiseptic / insecticide by the liquid spraying device 9, and the antiseptic / insecticide is applied to the connection or joint of the material to be treated w. It penetrates to an appropriate depth on the entire peripheral surface including the surface.

In this example of use, the case where an antiseptic and insecticide is applied to architectural wood such as pillars and beams has been described. However, the present invention is not limited to this. For example, a coating solution or the like is supplied to the solution tank 25. By doing so, it is possible to quickly and uniformly apply a coating liquid or the like to various materials to be processed such as a flat plate or a round bar.

[0032]

According to the present invention described above, it is possible to stably and efficiently apply and penetrate an antiseptic, insect and insect repellent to each piece of architectural wood, such as a pillar or a beam, using a compact device. Thus, the processing cost is greatly reduced, and a small number of workpieces can be efficiently processed.

According to the second aspect, the scattering of the liquid material can be prevented by a simple means, the dust adhered to the material to be processed can be removed, and the liquid material excessively adhered to the material to be processed is scraped off. Can be done.

According to the third aspect of the present invention, the liquid agent sprayed and rebounded from the material to be processed does not reduce the force of the liquid agent ejected from the slit for the liquid passage, so that the liquid agent can be stably supplied from the slit for the liquid passage. It will be injected. According to the fourth aspect, the liquid agent can be efficiently supplied to the annular liquid chamber.
