材料を圧縮して一定形状に成形して取扱いを容易ならし

れる。[Detailed Description of the Invention] For example, plant fibers such as Chigusa for feed! When the material 11 is collected and collected, it is generally in a coarse state with low density, so it is difficult to handle. For this reason, the material is compressed and molded into a certain shape to facilitate handling, and the quality is maintained by suppressing the circulation of internal air.
上記の例のごとく、不定形状の粗なる植物繊維性の材料
を一定形状に圧密するには、先ず比較的大形で低圧の圧
縮機を用いて予備圧縮を施し、次いで中形、中圧の圧縮
機で２次圧縮を施し、最後に比較的小形、高圧の圧縮機
で仕上圧縮を施すことが考えられる。As in the example above, in order to compact irregularly shaped coarse plant fibrous material into a fixed shape, first pre-compression is performed using a relatively large, low-pressure compressor, and then a medium-sized, medium-pressure compressor is used. It is conceivable to perform secondary compression using a compressor, and finally perform final compression using a relatively small, high-pressure compressor.

の場合、その繊維の配列に方向性が有るため、圧縮前の
材料の状態を個々に観察して圧縮方向を決めなければな
らないので作業員に熟練を要する上に、自動化乃至半自
動化が困難であること。(c) In many cases, the fibers of collected and bound plant fiber materials have a directionality, so the direction of compression must be determined by observing the state of each material before compression. Therefore, it requires skilled workers and is difficult to automate or semi-automate.

。In addition, rational energy distribution is performed according to the progress of the degree of consolidation of the amount of workpiece material, such as pre-compression at low pressure and high speed, secondary compression at medium pressure and medium speed, and final compression at high pressure and low speed. Not only can compression work be carried out efficiently, but also the pressure resistance of the mechanical equipment can be distributed rationally, so the total weight of the equipment is light and the manufacturing cost is low. It's over. Furthermore, as mentioned above, each of the three stages of compression is performed at right angles, so three types of compressors, which would otherwise be vertically long in a single device, must be arranged alternately orthogonally, reducing the space required for installation. can do.

じる。As detailed above, the compression molding method of the present invention is a method for compression molding a vegetable fibrous material, in which compression processing is performed sequentially and continuously at least three times using at least three compressors. After pre-compressing the vegetable fibrous material through the first compression to make the density of the material uniform, the material to be compressed after the above pre-compression is subjected to a second compression in a direction perpendicular to the first pre-compression. By performing compression and applying a third compression to the material to be compressed after completing the second compression, in a direction perpendicular to the second compression, the material can be transported during the compression process. Plant fibrous materials can be compression-molded efficiently in a narrow space without requiring any labor, and in addition, there is no need to separately consider the orientation of the plant fibrous material when starting the compression process, and it is possible to An excellent practical effect is produced in that an irregularly shaped raw material in a constant state can be compressed into a compact constant shape and the shape can be maintained.
