定尺物の亜鉛鍍鉄板の縁辺を折り曲げ組合せてダクトを
製作する方法は幾多とあるが、最近では定尺物の鉄板を

いわゆるボタンパンチ式の製作方法が多く採用されてい
る。(Prior art) There are many methods of manufacturing ducts by folding and combining the edges of standard-sized galvanized iron plates, but recently, a method has been developed to fabricate ducts using standard-length iron plates and a simple folding machine. A so-called button punch method of manufacturing is often used.
ボタンパンチ式のダクトについて詳細に説明すると、第

されている。To explain the button punch type duct in detail, Figure 2 shows the duct completed by combining (1
), the upper plate (2) is the side plate, and they are combined at the half-folded part of (3).

The end of the upper plate (1) has a vertical fold (4) bent at right angles, and the required number of buttons (5) are folded out with a press or the like toward the inner surface of the vertical fold (4) to form a hook.

クトの1隅を形成する。FIG. 8 shows a state in which the top plate (1) and side plate (2) are combined. A plurality of buttons (5) provided on the vertical fold part (4) of the top plate (1) are connected to the hook part (8) of the vertical fold part of the side plate (2).
), and once pushed in, these retaining relationships will not come off, and one corner of the duct will be firmly formed by the elasticity of the halves.
さて、このようにして製作されたダクトに必要に応じて
断熱、外装をして空調等に使用するのであるが、ダクト
内を流れる空調された空気は常に正圧であるため、この
種のハゼ折り構造では通常5〜10%の漏洩はやむを得
ないとされていた。Now, the duct manufactured in this way is insulated and sheathed as necessary and used for air conditioning, etc., but since the conditioned air flowing inside the duct is always under positive pressure, this kind of goby In folded structures, leakage of 5 to 10% was considered to be unavoidable.

れに反して完全な漏洩を防止できるものではなかった。However, in order to prevent even the slightest leakage, for the ducts combined as shown in Fig. 3, the sealing material (9) is applied from the outside as shown in Fig. 4 for the small duct, and the sealing material (9) is applied inside the duct for the large duct. For the items to be inserted, sealing material (9) was applied from inside the duct. These are manual operations that require a great deal of man-hours and, on the other hand, cannot completely prevent leakage.

注入は不能となる。Mechanism of the Invention (Means for Solving the Problem) As shown in Figure 9 (b), the galvanized iron plate is always in the shape of downward opening between ■1 and ■I. Then, in the final step ①, the folded part (3) is formed on the upper side of the iron plate. Therefore, in the downward-opening shape of (1) to (1), injection of the sealant causes "sagging" and is not suitable for automatic injection, and in the case after (1), the bending progresses and the injection of the sealant becomes impossible.
上記の事実をもとにして、従来の上側ローラと下側ロー

にて連続シール材の注入を行なうこととした。Based on the above facts, the conventional upper roller and lower roller are arranged upside down, and in the ■th step, the folding angle of the half-fold is set to the opening direction, and the folding angle is set between the steps of ■ and ■. We decided to perform continuous injection of sealing material.

is set larger than the opening angle αC in the conventional step 1, so that the injection of the sealing material can be easily received while the opening angle is large between 2 and 3 upwards.

Effects of the Invention In the present invention, the upper roller and lower roller of the conventional button punch and edge folding machine are replaced, and the shape of the roller in the step (i) is changed to a cross-folding roller that can be opened more easily than before. This makes it possible to supply an appropriate amount of sealing material continuously between the ■ process and the ■ process, which not only eliminates the manual process for sealing, but also provides a duct with extremely low leakage, which is highly effective. There is something.
