URETHANE FOAM FORMATION SYSTEM
To provide a system for forming urethane foams having different compositions in a more convenient mode.SOLUTION: A supply changeover part 32 for supplying any one raw material among a plurality of raw materials to a supply port of a measuring supply part 20 is provided, which prevents a first raw material 12a before changeover in changeover work from being mixed with a second storage space 11b for storing a second raw material 12b after changeover. Inlet side valves 521a and 521b are provided on a plurality of discharge pipes 51a and 51b branched from a discharge port 231 of the measuring supply part, which prevents the first raw material remaining in the discharge pipes in changeover of the raw material from reversely flowing to the measuring supply part. Outlet side valves 522a and 522b are provided on a plurality of discharge pipes, which allows reduction of a waste amount of the first raw material before changeover remaining in a gun hose 532a in changeover of the raw material.SELECTED DRAWING: Figure 1
【課題】より利便性の高い態様で、組成の異なるウレタンフォームを形成することが可能なシステムを提供する。【解決手段】複数の原料から何れか一つの原料を計量供給部２０の供給口へと供給可能な供給切替部３２を設けることで、切替作業時に切替前の第１の原料１２ａが、切替後の第２の原料１２ｂを収容する第２の収容空間１１ｂに混ざる恐れを防止する。また、計量供給部の吐出口２３１から分岐する複数の吐出管５１ａ、５１ｂに入口側バルブ５２１ａ、５２１ｂを設けることにより、原料の切替時に吐出管に残っている第１の原料が計量供給部に逆流する恐れを防止する。また、複数の吐出管に出口側バルブ５２２ａ、５２２ｂを設けることにより、原料の切替時にガンホース５３２ａに残った切替前の第１の原料の廃棄量を減らすことができる。【選択図】図１
