Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for painting a corner portion of a three-dimensional frame structure assembled from steel frames, wood and other building materials.

[0002]

[Prior Art]

 Conventionally, when painting the corners of these frame structures, to prevent the paint from adhering to areas other than the required areas, the areas where paint should not adhere are covered with adhesive tape or vinyl sheets, and then brushed. Painting is done by techniques such as spray painting and roll painting.

[0003]

[Problems to be solved by the device]

 A large number of frame units are used for buildings, etc., but when painting the welding points of those corners, the coating surface is complicated, so a uniform coating can be obtained by brush painting and roll coating. It is also difficult to prevent the paint from dripping, which is difficult and causes stains. On the other hand, although spray coating with a spray can obtain a uniform coating film, spray coating from multiple directions is required, and therefore the spray of paint mist spreads in multiple directions, making it difficult to collect mist. The problem of environmental pollution is unavoidable. The present invention has been made in order to solve the problems of these coating methods, and its purpose is to provide a new coating apparatus capable of obtaining a uniform coating film without causing environmental pollution. Is what you are trying to do.

[0004]

[Means for Solving the Problems]

 The purpose of the above is to have a shell-shaped wall structure with a wide opening, each wall has an exhaust pipe connection port, and the openings are anastomosed to each other to form an aggregate of the skeleton structure at the anastomosis. A plurality of shells that can form a booth that surrounds the corner portion in a substantially airtight manner, leaving a through hole, an exhaust blower connected to the exhaust pipe connection port of each shell via an exhaust pipe, and a paint provided inside the booth. It is provided inside the spray nozzle and each shell, and the inner space of each shell is divided into a space leading to the exhaust pipe and a space where the paint spray nozzle exists, and the space where the paint spray nozzle exists leads to the exhaust pipe. This is achieved by the above-mentioned corner portion coating device of the frame structure, which comprises a filter capable of collecting paint mist in the air flowing toward the space, and an operation control device for the paint spray nozzle.

The horizontal and vertical bones at the corners of the frame structure penetrate through the aggregate through holes formed between the shells when the shells are connected to form a booth, and thus the frame structure is formed. The corners are enclosed inside the booth and spray-painted by a paint spray nozzle. During the painting process, the paint mist scattered around is sucked together with the air flow in the booth by the exhaust blower and is collected when passing through the filter provided in the booth, so it is released to the atmosphere. There is no.

It is desirable that each of the above-mentioned paint spray nozzles be capable of swinging around the respective nozzles and movable along the aggregate within the booth. The position and posture of the paint spray nozzle are controlled from outside the booth. In addition, the filter installed inside the booth shall have a structure that is not easily blocked by paint mist, and shall be structured so that it can be easily removed and replaced. In addition, two or three shells that surround the corners are connected to each other, so it is preferable that they be attached to a common pedestal so that they can move vertically and laterally, respectively.

[0007]

[Action]

 The skeleton corner coating device according to the present invention encloses the skeleton corner part in a booth equipped with a paint spray nozzle, a paint mist collecting filter, and an exhaust device, and spray paints the skeleton corner part while collecting paint mist inside the booth. Therefore, a homogeneous coating film can be obtained without releasing harmful paint mist to the outside.

【Example】

 Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a three-dimensional exploded view showing the relative positions of the corners of the frame unit, which is the object to be coated, and the constituent elements of the corner coating apparatus according to the present invention. FIG. 2 is the corner coating apparatus according to the present invention. FIG. 3 is a partially enlarged cross-sectional view showing an example of the cross-sectional structure of the filter, which is a perspective view showing a usage state. Thus, in the drawing, 1 is a corner portion of the frame structure, 2, 3 and 4 are first, second and third shells, 5, 6 and 7 are paint spray nozzles, 8, 9 and 10 are The holders 11, 12 and 13 of the paint spray nozzles 5, 6 and 7 are filters for collecting paint mist. The first shell 2, the second shell 3 and the third shell 4 have upper lids 2b, 3b and 4b attached to the upper portions thereof by hinges 2a, 3a and 4a so as to be openable and closable, and filters 11, 12 and 13 when opened. Are installed so that they can be replaced.

Further, the shells 2, 3 and 4 are provided with holes 2d into which the holders 8, 9 and 10 of the paint spray nozzles 5, 6 and 7 are inserted from the outside, slits 3d and 4d and an exhaust pipe connection port. The exhaust pipes 2e, 3e and 4e connected to an exhaust blower (not shown) are connected. In the state shown in FIG. 1, the first shell 2, the second shell 3 and the third shell 4 have openings indicated by ABCDEFGHIJKLMNA, ABCDEFGHHOPQRA and ANMLKJIHSPQRA, respectively, and these openings are formed. When assembled as shown in FIG. 2, they are configured to anastomoze each other at the portions of the signs to form a substantially sealed booth. Although not shown for simplification of the drawing, these shells are attached to an appropriate supporting device or a pedestal so that they can be connected to each other by anastomosing the openings, and are supported so that they can be horizontally moved, lifted, and rotated. In addition, guides and latches are provided in appropriate places.

Thus, in the illustrated embodiment, the longitudinal bone 1a of the corner portion 1 of the frame structure is a square steel, and the transverse bones 1b and 1c are both channel steels. The longitudinal bone 1a penetrates a rectangular gap formed between the opening edge HOP of the second shell 3 and the opening edge HSP of the third shell 4, and the transverse bone 1b of the first shell 2. The opening edge CDEF penetrates a gap formed between the opening edge CDEF and the opening edge CDEF of the second shell 3, and the transverse bone 1c forms the opening edge JKLM of the first shell 2 and the opening edge JK of the third shell 4. It penetrates the gap formed between the LMs. Therefore, as shown in FIG. 2, the corner portion 1 of the frame structure is taken into the booth defined by the above three shells. Inside the booth, paint spray nozzles 5, 6 and 7 are provided facing the surface of the frame structure to be painted. The paint spray nozzles 5, 6 and 7 are attached to holders 8, 9 and 10 which are inserted through insertion holes or slits provided in the corresponding shells, and are horizontally moved, lifted and rotated by a device (not shown). And the spray of paint is controlled.

The insertion holes, slits, etc. of the paint spray nozzle holders 8, 9 and 10 can also be provided on the side wall or ceiling of the shell. The holder does not have to be a single rod-shaped body inserted from the outside of the booth, but can be, for example, an articulated arm attached inside the booth. When using such an articulated arm, it is recommended to provide not only a paint spray nozzle but also an infrared video camera or other sensor. Further, it goes without saying that the number and orientation of the paint spray nozzles and the method of moving the paint spray nozzles are appropriately changed according to the shape and arrangement of the surface to be painted, the purpose of painting and the ability of the holder. The exhaust pipes 2e, 3e and 4e are connected to an inlet of an exhaust blower (not shown) via a header (not shown). By operating the exhaust blower before the start of coating, the airflow passing through the filters 11, 12 and 13 is generated and the inside of the booth is exhausted.

When the painting operation is started, the paint mist scattered inside the booth is sucked by the airflow passing through the filters 11, 12 and 13, and is collected by the filter to remove the paint mist. The exhaust gas is discharged from the exhaust blower discharge port through the exhaust pipes 2e, 3e and 4e. The location of the exhaust pipe connection port can be on the side surface or the bottom surface in addition to the top of the booth shown in the figure. If a large amount of exhaust gas is emitted and it is odorous and may cause environmental pollution, it may be released into the atmosphere after being burned. It is recommended that the filters 11, 12 and 13 for collecting paint mist that scatters during paint work have a replaceable structure, for example, that each shell be provided with an insertion hole for extraction and replacement. And such insertion holes are provided on the top, side or bottom of each shell.

Therefore, it is desirable that the filter material of the filter has a structure in which clogging due to the paint mist is unlikely to occur, as shown in FIG. In FIG. 3, 131 and 132 are baffle plates provided with a large number of holes, 133 is a distance piece, 134 is a filter medium made of sponge or non-woven fabric, and 135 is a metal fitting for retaining the filter medium. When exhaust gas containing paint mist passes between baffle plates, the flow direction is suddenly changed. The filter material is less likely to become clogged. When changing the filter material, change the pressure loss of the filter as a guide, and wash the filter material removed from the booth with a solvent such as lacquer or thinner or water, and use it repeatedly.
