Device for separating doses of plastics material

摘要

A device for separating a plurality of doses of plastics from a plurality of extruder outlets (2,3) comprises a movable element that carries two groups of dose separating elements (A) wherein at least a first group is movable with respect to at least a second group. The separating device expels the doses in a circular arrangement for subsequent compression molding of a liner (17,18) for a container closure (C).

主权项

1. A device for separating doses of synthetic plastics, comprising
(a) an extruding device for extruding synthetic plastics comprising a first group of extruder outlets and a second group of extruder outlets arranged at a higher elevation than said first group of extruder outlets; (b) a movable element that is movable in an advancing direction along a closed loop path which passes adjacent said extruding device for each revolution of said movable element; (c) at least one first group of dose separating elements mounted on said movable element, said first group of dose separating elements separating and removing doses of synthetic plastics from said first group of extruder outlets, respectively, as said first group of dose separating elements passes said first group of extruder outlets for each revolution of said movable element; and (d) at least one second group of dose separating elements mounted on said movable element, said second group of dose separating elements separating and removing doses of synthetic plastics from said second group of extruder outlets, respectively, as said second group of dose separating elements passes said second group of extruder outlets for each revolution of said movable element; wherein said first group of dose separating elements is vertically movable on said movable element between a first raised configuration above said second group of extruder outlets in which said first group of dose separating elements does not interfere with said second group of extruder outlets or with the synthetic plastics that exit therefrom during movement of said movable element along said closed loop path, and a second lowered configuration in which said first group of dose separating elements is adjacent said first group of extruder outlets, said first group of dose separating elements being moved to said first configuration after passing said first group of extruder outlets and before passing said second group of extruder outlets and being moved to said second configuration after passing said second group of extruder outlets and before passing said first group of extruder outlets, for each revolution of the movable element.
