Description

  The present invention relates to a method for transporting and assembling large and small box-shaped units that blow and supply clean air into a clean room equipped with precision equipment.

  In a clean room equipped with semiconductor manufacturing facilities, clean air is blown out and supplied from a large number of large and small box units installed on the ceiling and / or wall surface. In order to install a large number of box units of various sizes according to the area, shape, etc., and to fit a support frame for installation, etc. Box-type units that are several centimeters large and small must be produced.In addition, clean air blow-out devices that are sized according to the size of each outer box are individually housed and installed in the outer box. It takes a lot of work, and therefore it takes a lot of time to assemble a large and small box-shaped unit, and because it is not compatible, it cannot be made up. In order to solve this problem, the applicant of the present application previously described in Japanese Patent Application No. 2008-168602 that the blowout device for clean air accommodated in a large and small outer box is made into a single size. Invented a shared module that can be used in common, and proposed the efficient assembly of large and small box units.

Japanese Patent Application No. 2008-168602

  However, in order to produce a box-shaped unit, an assembly line with facilities for aligning and fitting the shared module in the outer box and a shared module that is surrounded by the outer box and becomes blind. Packing material that requires skilled workers to fix, and has excellent shape-retaining properties to prevent the assembled box unit from being damaged during transportation by collision, impact, or rubbing between each other. There was a problem that had to be packed robustly.

Furthermore, the assembled large and small box-type units are bulky due to the box shape, and the number of containers that can be loaded in the transport container is very small. Therefore, the number of transportation to the installation site is increased and the transportation cost is increased. As a result, there is a social problem that the amount of CO ₂ emitted from transport vehicles increases, and there are many problems such as having to secure a large storage place for many box units at the installation site. was there.

  In particular, box-shaped units that are larger or smaller than the standard size, such as several millimeters to several centimeters as described above, may be left unloaded when loaded into a container car or the like because a small gap that cannot be loaded is generated. There was a problem.

In the present invention, the box-type unit is assembled before it is assembled, that is, the shared module for blowing clean air, the large and small outer boxes, the mounting member and the filter are separately transported to the installation site, and can be easily assembled at the installation site. I made it possible.
Especially for the outer box, in order to increase the transport efficiency and facilitate the assembly, a large number of sheets can be stacked and transported with a buffer member sandwiched between them without being bulky. This problem was solved by forming inclined side plates connected at a fixed inclination angle on the four sides, and transporting the outer box outside the standard size by stacking and transporting it to the installation site without leakage. It is.

  Since the outer box constituting the box-shaped unit has an inverted square dish shape, a large number of sheets can be transported at one time without being stacked and bulky, resulting in the effect of dramatically improving transport efficiency. . Large and small outer boxes outside the standard size, such as several millimeters to several centimeters in size, can be transported without being left over by being stacked and transported.

  By setting the inclination angle of the inclined side plate to the optimum angle, it is possible to densely lay the cushioning material between the contacted areas and between the outer boxes, thereby preventing mutual scratches.

  The outer box has an inverted square shape, which eliminates the need for an assembly line and can be easily screwed and attached without the need for skill by visual inspection, making it extremely easy to assemble a box unit. Is produced.

As a result, the number of times of transportation of container vehicles or the like is reduced, and the CO ₂ emission amount is greatly reduced, and the transportation cost can be reduced.
In addition to eliminating or simplifying the packaging for transporting the outer box, stacking and storing at the installation site in the same manner as at the time of transport produces an effect of eliminating the need for a large installation site.

In the present invention, a large number of large and small box-type units that blow out and supply clean air are transported from the factory to the installation site according to the parts before assembly, and assembled into large and small box-type units by simple means by screwing at the installation site. So that it can be installed on the ceiling or wall of a clean room.
To make transportation more efficient and easier to assemble, the outer box has an inverted square plate shape with inclined side plates on the four sides of a rectangular top plate, enabling unobtrusive contact area stacked transportation, and installation site Then, the box-type unit can be easily assembled by screwing the end of each inclined side plate to the framed filter.

  1 to 3 show a first embodiment, in which the outer box 3 is formed in an inverted square dish shape in which a rectangular top plate 3a and an inclined side plate 3b are integrally provided on the four circumferences thereof. The height of the inverted square dish is a height at which the shared module 2 can be accommodated. The framed filter 5 is formed with a frame 5a around the four sides so that the screw 7 can be easily fixed to the outer box 3.

  The mounting member 4 is formed to have the same width as the outer box 3, and the planar end portions are respectively exposed from the slits 3 d provided in the middle of the opposite inclined side plates 3 b, and screwed to the framed filter 5 together with the outer box 3. 7, and the screw 7 is fixed to the mounting member 4 on the rear surface of the shared module 2.

From the factory, each of the shared module 2, the outer box 3, the mounting member 4, and the framed filter 5 is transported toward the installation site in different states.
Since the outer box 3 has an inverted square dish shape, the contact area can be piled up without being bulky, and a large number of sheets can be transported at a time.

  By setting the inclination angle of the inclined side plate 3b to 17.5 degrees with respect to the top plate 3a or in the vicinity thereof, a gap of less than 2 mm is created between the stacked top plates 3a, and a buffer material K having a thickness of about 2 mm is laid in the gap. It is possible to prevent scratches and the like from entering. As a result, a large number of stacked outer boxes do not require strict packing with a packing material excellent in shape retention, reducing the trouble of packing and opening, and saving packing material resources.

At the installation site, the box-shaped unit 1 is assembled after the arrival of each member. Since the outer box 3 has an inverted square shape, the common module 2 can be easily inserted by screwing it 7 while visually observing the shared module 2, and the framed filter 5 can be easily obtained by aligning the frame 5a with the flange of the outer box 3. Screw 7 can be fixed to
The common type module 2 is fixed by fixing the front surface with the edge of the intermediate opening 3c of the top plate 3a and the back surface with the attachment member 4 with screws 7 respectively.

  Thus, the large and small box-shaped units 1 required by the installation site and the non-standard large and small-sized box-shaped units 1 manufactured in accordance with the difference in the support bone structure can be easily assembled and arranged.

  FIG. 4 shows a second embodiment in which an inverted square dish-shaped outer box 3 is produced in a state where there are no inclined side plates 3b on two relative sides, and the remaining two sides of the inclined side plates 3b are installed before or after transportation. This is the same as the previous example except that is welded.
