【発明の詳細な説明】 本発明は連続的に生産される複合材を所定の長さずつに
切断する方法および装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for cutting continuously produced composite materials into predetermined lengths.

例えば建築物のサイディング材に用いられている複合材
は金属の表面材と発泡合成樹脂の芯材と防水性の裏張材

共に防火、断熱、遮音等の機能を有していることから広
く使用されている。For example, composite materials used in building siding materials are composed of a metal surface material, a foamed synthetic resin core material, and a waterproof lining material, and are lightweight and easy to handle, as well as providing fire protection, heat insulation, and It is widely used because it has functions such as sound insulation.

尺帯状の複合材１１が連続的に生産される。Such composite materials are produced continuously in a factory. For example, as shown in Fig. 3, a metal plate 1 made of galvanized iron plate and coiled is fed out and molded into a predetermined cross section by a forming machine 2. A shaped surface material 3 is formed, and then a liquid raw material of room-temperature curing resin is supplied onto the surface material 3 by a feeder 4. Furthermore, a backing material 5 is layered on top of the surface material 3, and an endless metal strip facing upward and downward is formed. The metal plate 1 is made from one coil by feeding the liquid raw material into a mold 8 formed between 6 and 70, foaming the liquid raw material in this mold 8 to create a core material 9, and sending it out. When the feeding is finished, the rear end is connected to the tip of the metal plate 1 fed out from the next coil by the connecting machine 10, and during operation, it is sent to the forming machine 2 and mold 8 in an endless state, thus forming an endless long strip. of composite material 11 is continuously produced.

前記において、表面材３は裏返しの状態で送られるもの

われた複合材１１、または第２図に示したように二つの
表面部３ａ。In the above, the surface material 3 is sent upside down, and as shown in FIG. 1, rising portions 3b, 3c, protruding edges 3d, and insertion grooves 3e are provided on both sides of the surface portion 3a by bending. a composite material 11 filled with a core material 9 and covered with a backing material 5, or two surface portions 3a as shown in FIG.

３ａが突出縁となる連結部３ｆによって並列一体に形成
されそれぞれに芯材９、裏張材５を有する複合材１１が
得られ、型８から送出されたとき所定長さずつに切断し
更に第２図の場合は連結部３ｆの中央で切断して製品と
する。A composite material 11 is obtained, which is formed in parallel and integrally by connecting portions 3f where 3a is a protruding edge, and has a core material 9 and a backing material 5, respectively.When fed out from a mold 8, it is cut into predetermined lengths and In the case of Figure 2, the product is cut at the center of the connecting portion 3f.

このような構造の複合材１１は突出縁３ｄを差込溝３ｅ

れた複合材１１の切断の時間間隔が短くなることは明ら
かで、例えば走行速度毎分３０メートルで３メートル長
さに切断するには切断装置が毎分１０回作動しなければ
ならない。In the composite material 11 having such a structure, the protruding edge 3d is inserted into the groove 3e.
The molds are connected to each other by being inserted into the molds, making construction extremely easy. However, in the manufacturing line shown in Figure 3, the mold 8 part is heated to shorten the foaming time of the liquid raw material. By doing so, it is possible to improve production efficiency and run the surface material 3 and the backing material 5 at a high speed of 30 meters per minute or more, so that the time interval for cutting the composite material 11 sent out from the mold 8 can be reduced. It is clear that the length of the cutter is shorter; for example, to cut a length of 3 meters at a running speed of 30 meters per minute, the cutting device must operate 10 times per minute.

また、複合材１１は金属からなる表面材３と、フレタン

縁３ｄ。The composite material 11 is made of a surface material 3 made of metal, a core material 9 made of foam such as phrethane resin, phenol resin, or epoxy resin, and a synthetic resin film, waterproof paper, metal foil, or a laminate thereof. The lining material 5 is flexible and waterproof, and is made of a combination of materials with completely different properties, and has protruding edges 3d on both sides.

差込溝３ｅ更に立上り部３ ｂ ｔ ３ ｃを有してい
るので切断するのがきわめて困難である。Since the insertion groove 3e further has a rising portion 3b t3c, it is extremely difficult to cut it.

ばならなかった。In other words, it is necessary not to reduce production efficiency by cutting continuously produced long strip-shaped composite materials while they are running without stopping each time, and to cut the composite materials with beautiful cuts to reduce yield and product value. Although there is a demand to prevent this from occurring, there is no cutting technology that allows for beautiful cuts, and as a result, the operating speed of the production line has had to be limited.

The composite material 11 is in contact with the upper surface of the composite material 11
Almost at the same time, the first upper blade 23 descends until it comes into contact with the backing material 5 (Fig. 14A), and then the upper holding member 5
8 increases the holding force as the spring 67 is compressed, and the first upper blade 23 shears the backing material 5 and the core material 9 and stops when it reaches the back surface of the facing material 3 (FIG. 14B).

rotates inward and is also extracted from the cutting location, and then the horizontal blade 57 is retreated, the first upper blade 23 is extracted from the cutting location, and the upper holding member 58 is lifted to release the composite material. As a result, a cutting point as shown in FIG. 14E is obtained.

切断するのである。As described above, the present invention provides a pair of first parts in which the relatively flexible and easily torn or crushed parts of a composite material made of a combination of materials with completely different properties, that is, the backing material and the core material, are arranged in front and behind each other. Since cutting is performed by the upper blade, this upper blade must be formed sufficiently thin so that when the backing material is sheared, it will not be pulled and the vicinity of the cut will be torn, or the core material will be crushed when sheared. It can cut into a cut with the same cross-sectional shape, and the second upper blade that cuts the hard surface material is inserted between the front and rear cuts while being shielded by the first upper blade, making it sufficiently thick. This allows the surface material to be reliably cut without affecting the cut edges of the lining material and core material.

ある。Therefore, two types of upper blades are used to cut parts of the composite material with different properties, resulting in a beautiful cut surface. If there are grooves, the third upper blade, which rotates in conjunction with the 20th upper blade, can cut these upwardly rising parts without worrying about crushing them. Composite materials made of a combination of different materials and having a complicated cross-sectional shape can be cut without causing waste due to cutting failures or producing irregular cuts that reduce commercial value.

そして本発明によると、製造装置から連続的に送出され

同一速度で各上刃を移動させながら切断するものである
から、複合材が高速度で製造されていても支障なく美麗
な切口に切断し生産能率を低下させないのである。According to the present invention, when the composite material continuously fed out from the manufacturing device approaches a predetermined length, each upper blade is moved in the composite material feeding direction, and when the predetermined length is reached, the upper blade is moved at the same speed as the feeding speed. Since each upper blade is moved while cutting, even if composite materials are manufactured at high speed, they can be cut into beautiful cuts without any problems and do not reduce production efficiency.

更に各上刃を装備して複合材送り方向に往復動する台車
を複合材の幅方向のずれに倣い動作する架台に載せたの
で、各上刃は常に正確に所定の部分を分担して切断し、
切断されない部分を生じる等の不都合を生じない等の効
果を有するものである。Furthermore, each upper blade is equipped with a cart that reciprocates in the composite material feeding direction and is mounted on a pedestal that follows the deviation in the width direction of the composite material, so each upper blade always cuts the designated portion accurately. death,
This has the effect of not causing inconveniences such as uncut portions.
