Blister-foil packaging machine

摘要

A lower foil formed with upwardly open filled pockets passes horizontally at a constant transport speed through a work station of a machine frame. A support table holds an upper tool immediately above the foil in the station. A double parallelogrammatic linkage has two upper pivots on the support table, two lower pivots on the machine frame, and two upright links pivoted on the upper and lower pivot. A table drive mounted on the frame includes a crank connected to the link for oscillating the link about the lower pivot and thereby reciprocating the support table generally in the transport direction. A lower tool is carried by guides on the support table for only vertical movement relative to the support table. A tool drive mounted on the frame includes another crank connected to the lower tool for reciprocating the lower tool vertically relative to the support table.
