Abstract
A press-and-blow container making machine wherein one of two rotary tables supports a set of blank molds receiving gobs from a gob feed and the other rotary table supports a set of blow molds serving to convert parisons obtained from the blank molds into finished containers. An endless flexible conveyor carries neck rings which transport parisons from the first table, past a preliminary treating unit and on to the blow mold. The neck rings also transport finished containers away from the blow molds.
Claims16
In a machine for the production of bottles or like hollow articles from plasticizable material, a combination comprising a mold construction including an upright bottom member, an annular neck ring located above and spaced from said bottom member and having an opening located substantially on a common axis with said bottom member, gripper means having a pair of halves movable between an open and a closed position, and a pair of mold center part halves carried by said gripper means between said neck ring and said bottom member movable with said two halves of said gripper means between said open and said closed position to define in said closed position with said neck ring and said bottom member a cavity of said mold, one of said pair of halves having opposite end portions respectively engaging in said closed position said neck ring and said bottom member and shaped to center said neck ring and said bottom member with respect to said center part, said halves of said gripper means being mounted for pivotal movement about a pivot axis parallel to said common axis;
- and means for moving said halves of said gripper means about said pivot axis between said open and said closed position.
In a machine for the production of bottles or like hollow articles from plasticizable material, a combination comprising a first turntable turnable about a first vertical axis and carrying a plurality of circumferentially spaced first mold means movable with said first turntable about said first vertical axis;
- a second turntable spaced from said first turntable and turnable about a second vertical axis, said second turntable carring a plurality of circumferentially spaced second molds means for movement with said second turntable about said second vertical axis;
- endless conveyor means extending between and encircling a portion of each turntable for movement in synchronism therewith;
- a plurality of neck rings carried by said conveyor means spaced therealong in correspondence with the spacing of said mold means on said turntables so as to be brought by movement of the latter in substantial alignment with said first and second mold means;
- first means carried by said first turntable and cooperating with said first mold means and said neck rings for converting gobs of plasticized material fed thereinto into parisons having ends located in the neck rings respectively aligned with said first mold means;
- second means carried by said second turntable and cooperating with said second mold means and said neck rings for converting parisons carried by said neck rings into finished articles;
- each of said mold means comprising a bottom member and a pair of complementary center part halves, and including gripper means for each of said mold means and having a pair of halves movable between an open and a closed position and respectively carrying said center part halves for movement therewith between said open and said closed position, one of said pair of halves having opposite end portions respectively engaging in said closed position said bottom member and a neck ring substantially aligned therewith so as to center the neck ring with the respective bottom member and the complementary center part halves along a common axis, said halves of said gripper means being mounted for movement about a pivot axis parallel to said common axis;
- and means for moving said halves of said gripper means about said pivot axis between said open and said closed position.
