US Patent:

44327200, Feb 21, 1984

Filed:

Jan 25, 1983

Appl. No.:

6/460830

Inventors:

James G. Wiatt - Cincinnati OH
James W. Calvert - Cincinnati OH
Samuel L. Belcher - Cincinnati OH
Roger D. Smith - Bethel OH

Assignee:

Cincinnati Milacron Inc. - Cincinnati OH

International Classification:

B29C 1707

US Classification:

425534

Abstract:

A machine for high rate production of molecularly oriented thermoplastic bottles is disclosed. The machine is of the reheat-and-blow type. A blow molding station simultaneously blow molds article preforms arranged in matrices by modular article carriers for conveying the preforms and articles through the machine. The carriers are designed to retain the performs throughout all operations of the machine from a preform load station through a thermal conditioning section, a blow molding station, and to a bottle eject station, thereby eliminating the need for other preform transferring apparatus. The article carriers together with the associated conveying apparatus comprise a sufficiently flexible structure that minor misalignments of the carriers with the blow molding mechanism do not adversely affect bottle production. Both loading of preforms and ejection of finished bottles are accomplished by operation upon matrices of preforms and bottles as defined by the carriers and conveyor lanes.

Appl. No.:

6/560571

Inventors:

James W. Calvert - Cincinnati OH
Samuel Belcher - Cincinnati OH

Assignee:

Cincinnati Milacron Industries, Inc. - Cincinnati OH

International Classification:

B29C 1707

US Classification:

264533

Abstract:

A blow molding machine is provided with an external center pin so that blowing is accomplished without introducing a mechanical or rigid member within the preform and/or bottle. To do this, the blowing is done by introducing a fluid, preferably a gas such as air, into the preform to expand it. Outside of the preform, meanwhile, is the subject center pin or center rod which is located on the preform center line (axis) and near the middle of the preform bottom. The rod receives a gate disposed centrally on the bottom of the preform when the preform is expanded by the entering fluid. In this manner, the center part of the bottom of the preform is engaged by the center pin which thereafter keeps the preform on center as the blowing action continues. A process is disclosed of blowing using a compressed fluid alone inside the preform to expand the preform axially against the bias of an external resiliently biased center pin.

Assignee:

Cincinnati Milacron Inc. - Cincinnati OH

International Classification:

B65G 4300

US Classification:

198341

Abstract:

An apparatus and method are disclosed for transporting products to and from the machine function operating stations of an integrated machine. The apparatus provides a table for carrying the products which is rotatably indexed by a drive system as required by the overall machine cycle of operation. The indexing drive system comprises an indexer, a driving motor, a brake, means for monitoring the orientation of the table and indexer input and circuitry operative to control the motor and brake to execute the cycle of operation of the indexer while simultaneously initiating activity of the machine operating station mechanisms in accordance with the disclosed method.
