TRANSFER DEVICE IN PLASTIC HOLLOW VESSEL MANUFACTURING MACHINE

摘要

PURPOSE:To enable the title device to perform transfer of preform and a vessel smoothly, by a method wherein both fixation of the preform to a mandrel through insertion into the mandrel and taking out operation of the vessel from the mandrel are performed continuously within a unit device. CONSTITUTION:Preform comprised of plastic is fed to a mandrel 10 with a feed mechanism 30 and preheated at a stretching temperature. An attaching and detaching mechanism 50 between a preheating mechanism 100 and molding mechanism 200 puts preform 1 on the mandrel 10 and separates a hollow vessel 20 from the mandrel 10. A changing mechanism 60 is provided between the preheating mechanism 100 and molding mechanism 200 and the preheated preform 1 is transferred into a mold of the molding mechanism 200. A transfer mechanism 70 of the supporting mandrel 10 for the preform is provided between the turreted attachment and detachment mechanism 50 and the preheating mechanism 100. A taking-out mechanism 80 is provided between the molding mechanism 200 and attachment mechanism 50. Then the hollow vessel 20 obtained through stretching blow molding is removed from the mandrel and discharged.
