Abstract

Vertically aligned first (30) and second (32) combined blowhead and takeout mechanisms are provided to sequentially blow glass parisons (P) into containers (C) in a mold set (22) and to transfer blown containers to a deadplate (40) of a glass containing forming machine (20). Each of the combined mechanisms is pivotally suspended about an axis A from a carrier arm (36) that is pivotally attached to an end of an oscillating arm (38), an opposed end of which is pivoted about an axis (B). The axis (B) of each combined blowhead and takeout mechanism is periodically raised and lowered to permit the other combined blowhead and takeout mechanism to oscillate therebeneath, to thereby permit overlapping cycles between the blowhead and takeout mechanisms. Each blowhead and takeout mechanism is provided with a chuck or tong assembly (54) to engage or release each container by its finish (F). Each tong assembly has a plurality of tong elements (74) that are simultaneously moved radially in or out by oscillation of a cam (50) that has a non-circular slot (78) in which a pin (76) carried by each tong element rides.

Claims3

Dependent claims

The process for blowing glass containers in a mold of a glass container forming machine and for transporting blown containers from the mold to a deadplate of the glass container forming machine, the process comprising:

providing a first combined takeout and blowhead mechanism;
injecting air into a first group of containers through the first combined takeout and blowhead mechanism while the containers are in the mold to blow preforms of the containers into containers;
grasping the first group of blown containers by the first combined takeout and blowhead mechanism;
transferring the first group of blown glass containers grasped by the first combined takeout and blowhead mechanism to a deadplate and releasing the first group of blown glass containers at the deadplate;
providing a second combined takeout and blowhead mechanism;
injecting air into a second group of glass containers being blown in the molds of the forming machine through the second combined takeout and blowhead mechanism while the containers are in the mold to blow preforms of the containers into containers;
grasping the second group of blown glass containers by the second combined takeout and blowhead mechanism;
and
transferring the second combined takeout and blowhead mechanism from the mold to the deadplate while transferring the first combined takeout and blowhead mechanism from the deadplate to the mold without contact between the first combined takeout and blowhead mechanism and the second combined takeout and blowhead mechanism.
