MACHINE FOR BLOW MOULDING CONTAINERS FROM A PARISON USING A CONTINUOUSLY ROTATING TURNTABLE

摘要

A machine (10) for blow molding containers (100). The machine (10) has a stationary flow head (26) located proximate a turntable (12) on which molds (16) are mounted. A dwell cam mechanism (110, 120, 132) on the turntable causes the molds to accelerate ahead of the turntable, stop under the flow head to receive a parison (31), then accelerate to catch up with the turntable. This sequence allows the turntable to rotate continuously. Blow pins (30) mounted on the turntable inject gas into the molds to blow mold the parison while traveling a first path (144). Paddles (142) grip the molded containers and travel a second path (146) radially outward from the first path. The containers blow-molded from the parisons at a first station (18) are retained on the turntable after the turntable completes one full revolution and again passes the first station.
