Neck crystallization system

摘要

The neck crystallization system includes a rectangular stage, a plurality of sprockets that are disposed on the stage, and an endless member that is fitted around the plurality of sprockets. A transfer path that is formed in an area in which the endless member is disposed, includes first to fourth linear transfer paths. A plurality of heating sections provided along at least the first to third linear transfer paths, a cooling section disposed along at least the fourth linear transfer path, a molded article supply section that supplies the molded article at a position on the upstream side of the plurality of heating sections, and a molded article removal section that removes the molded article at a position between the cooling section and the molded article supply section, are provided along the transfer path in which a plurality of transfer members that respectively support the molded article are transferred.

1. A neck crystallization system comprising:
a rectangular stage that has long sides and short sides in a plan view; a plurality of sprockets that are disposed on the stage; an endless member that is horizontally fitted around the plurality of sprockets; a transfer path that is formed in an area in which the endless member is disposed, and includes first to fourth linear transfer paths, the first to fourth linear transfer paths being parallel to each other, and extending in a direction along the long sides, transfer directions of two transfer paths among the first to fourth linear transfer paths that are adjacent to each other in a direction along the short sides being opposite to each other; a plurality of transfer members that are mounted on the endless member, and respectively support and transfer a molded article having a neck along the transfer path; a plurality of heating sections that are provided along at least the first to third linear transfer paths among the first to fourth linear transfer paths that are positioned on an upstream side, and heat the neck of the molded article; a cooling section that is disposed along at least the fourth linear transfer path that is positioned on a downstream side of the plurality of heating sections, and cools the neck of the molded article; a molded article supply section that supplies at least one molded article to at least one transfer member that is situated in the transfer path at a position on an upstream side of the plurality of heating sections; and a molded article removal section that removes at least one molded article from at least one transfer member that is situated in the transfer path at a position between the cooling section and the molded article supply section, the plurality of sprockets including one drive sprocket and first to fourth driven sprockets, the drive sprocket being disposed on an upstream-side end of the first linear transfer path, the first driven sprocket being disposed on a downstream-side end of the first linear transfer path and an upstream-side end of the second linear transfer path, the second driven sprocket being disposed on a downstream-side end of the second linear transfer path and an upstream-side end of the third linear transfer path, the third driven sprocket being disposed on a downstream-side end of the third linear transfer path and an upstream-side end of the fourth linear transfer path, and the fourth driven sprocket being disposed on a downstream-side end of the fourth linear transfer path, when an outer diameter of the drive sprocket is D1, each outer diameter of the first, second and third driven sprockets is D2 and an outer diameter of the fourth driven sprocket is D3, D1>D2≧D3 is satisfied.
