Title
(EN) PRODUCTION DEVICE AND PRODUCTION METHOD FOR PULP MOLD PRODUCT
(FR) DISPOSITIF ET PROCÉDÉ DE PRODUCTION DE PRODUIT DE MOULE POUR PÂTE À PAPIER
(JA) パルプモールド品の製造装置及び製造方法
Abstract
(EN) [Problem] To efficiently and repeatedly produce pulp mold products the inner surface and outer surface of which are both smooth. [Solution] The present invention comprises: a first mold 12 and second mold 14 with an outer peripheral surface 22 and inner peripheral surface 28 that are slidably engaged with each other along the vertical direction and define a storage chamber 20 the volume of which can vary; a pulp slurry supplying passage 46 provided in the second mold 14 from the outside of the mold to the mold surface that defines the storage chamber 20; a plurality of dewatering passages 34 provided in the first mold 12 from said mold surface to the outside of the mold; and a mold driving device 18 for driving the first mold 12 and second mold 14 along the vertical direction such that the first mold 12 and second mold 14 can be displaced relative to each other and that the following states can be taken: a first mold fasten state for making the volume of the storage chamber 20 a first volume in order for the storage chamber 20 to receive pulp slurry; a second mold fasten state for making the volume of the storage chamber 20 a second volume less than the first volume in order to dewater the pulp slurry; and a mold opened state which is taken when the storage chamber 20 should be opened.
(FR) Le problème à résoudre par la présente invention est de produire de manière efficace et répétée des produits de moule de pâte à papier dont la surface interne et la surface externe sont toutes les deux lisses. La solution selon l'invention comprend : un premier moule (12) et un second moule (14) ayant une surface périphérique externe (22) et une surface périphérique interne (28) qui viennent en contact coulissant l'une avec l'autre le long de la direction verticale et définissent une chambre de stockage (20) dont le volume peut varier; un passage d'alimentation en pâte liquide (46) formé dans le second moule (14) à partir de l'extérieur du moule jusqu'à la surface du moule qui définit la chambre de stockage (20); une pluralité de passages de déshydratation (34) formés dans le premier moule (12), de ladite surface de moule à l'extérieur du moule; et un dispositif d'entraînement de moule (18) pour entraîner le premier moule (12) et le second moule (14) le long de la direction verticale de sorte que le premier moule (12) et le second moule (14) peuvent être déplacés l'un par rapport à l'autre et pour que les moules prennent les états suivants : un premier état de fermeture de moule pour faire du volume de la chambre de stockage (20) un premier volume afin que la chambre de stockage (20) reçoive la pâte liquide; un second état de fermeture de moule pour faire du volume de la chambre de stockage (20) un second volume inférieur au premier volume afin de déshydrater la pâte liquide; et un état d'ouverture de moule qui est pris lorsque la chambre de stockage (20) doit être ouverte.
(JA) 【課題】内側面及び外側面の両面が滑らかな表面のパルプモールド品を繰り返し効率よく生産すること。 【解決手段】上下方向に沿って互いに摺動可能に嵌合する外周面22及び内周面28を有することにより、容積可変な貯容室20を画定する第1型12及び第2型14と、第2型14に、型外から貯容室20を画定する型面に至るように設けられたパルプスラリ供給通路46と、第1型12に、前記型面から前記型外に至るように設けられた複数の脱水通路34と、貯容室20にパルプスラリを受容するべく、貯容室20の容積が第1の容積となるようにする第1型締め状態、前記パルプスラリを脱水するべく、貯容室20の容積を前記第1の容積よりも小さい第2の容積となるようにする第2型締め状態、及び貯容室20を開放するべき型開き状態をとり得るように、第1型12及び第2型14を上下方向に沿って互いに変位可能に駆動する型駆動装置18とを有する。
