Patent number: 4351663Abstract: A dual-mode takeout mechanism is provided for use in, for example, an individual section glassware forming machine. In the normal mode of operation, the formed ware is transported in a fixed radius vertical arc from a molding station to a cooling station and released for further processing. In the reject mode of operation, defective formed ware is transported in an enlarging vertical arc from the molding station to a disposal station. An arm of the takeout mechanism is capable of extending in telescoping fashion, and is activated in the reject mode so as to begin the extension process as the takeout mechanism begins to transport ware from the molding station. A controller is provided to detect when the reject mode has been commanded. The reject mode can be entered for a desired number of cycles by computer command, sensor command, or operator command (manual entry). If the reject mode has been entered, the controller operates a solenoid controlled valve which extends the arm pneumatically.Type: GrantFiled: March 10, 1981Date of Patent: September 28, 1982Assignee: Ball CorporationInventor: Charles L.

Patent number: 4343644Abstract: An apparatus for making hollow glassware has at least one preform provided adjacent a turntable rotatable about an upright axis and carrying at least two angularly spaced final molds. The turntable can rotate about this axis so as to orbit the final molds through a transfer position close to the perform and a takeout position angularly offset from the transfer position and remote from the preform. At least one arm is provided above the turntable and final molds and carries at least two respective mold heads. This arm is pivotal about the axis with the mold heads being vertically alignable and engageable with the respective final molds. The arm and mold heads can be pivoted about the axis independently of the turntable and a source of air at a pressure different from ambient is connected to the mold heads through the arm.Type: GrantFiled: December 9, 1980Date of Patent: August 10, 1982Assignee: Veba-Glas AGInventors: Helmut Hullen, Werner-Dieter Knoth

Patent number: 4340413Abstract: In a glassware forming machine, a non-handed transfer mechanism, for transferring freshly-formed hot glassware, by swinging through a right angle about a vertical axis, from a dead plate to an adjacent conveyor, comprises a side-by-side parallel pair of rams having pistons on the free ends of which is a pusher plate. A piston stop bar is located centrally of the pistons and is connected to a piston tie plate for arresting the pusher plate and pistons at the end of an extending stroke of the pistons.Type: GrantFiled: January 2, 1981Date of Patent: July 20, 1982Assignee: E. R. Lattimer LimitedInventor: Roger G. Rowland

Patent number: 4325725Abstract: An apparatus comprising a parison forming assembly and a final shaping assembly each having a mold, and a reheating and intermediate forming assembly provided between the two assemblies and having a cover or an intermediate forming mold for enclosing the parison in a confined space, the assemblies being associated with one another for sequential operation. Without prolonging the molding cycle time usually needed for the parison forming assembly and the final shaping assembly, unfinished parisons can be reheated sufficiently.Type: GrantFiled: October 7, 1980Date of Patent: April 20, 1982Assignee: Yamamura Glass Kabushiki KaishaInventor: Masami Fujimoto

Patent number: 4298373Abstract: The take-out mechanism on a glass container forming machine is operated by the vertical reciprocation of a fluid motor. The movement of the tongs into position to grasp a new container is controlled so that the tong arm which is swinging through an arc of 180.degree. degrees, is cushioned in its final movement so as to avoid excessive vibration of the mechanism.The pressure introduced into the motor for moving the tong arm into position over the dead plate is also connected to a second piston which is spring-biased in relation to the piston rod of the motor. When the tong arm has completed its movement and released the container at the dead plate, the pressure is discontinued at both the motor and the second piston which results in the rod of the second piston actuating the motor rod to cause the tongs to be lifted a predetermined amount.Type: GrantFiled: January 14, 1980Date of Patent: November 3, 1981Assignee: Owens-Illinois, Inc.Inventors: Eustace H. Mumford, Jack I. Perry

Patent number: 4290795Abstract: A rotatable neck ring assembly for use primarily in an automatic blow molding machine includes an annular bushing and a concentrically arranged series of pivotally mounted foot members which in their closed position, cooperate with the bushing to grip the rim of a parison and hold it securely during the molding process. These pivoted foot members, which are spring biased to a closed position, are kept into firm engagement with the bushing by the upwardly moving parison mold. A first cam surface on the outer surface of the foot members cooperates with a corresponding surface on a concentrically surrounding sleeve to hold the foot members tightly against the bushing to grip the rim of the parison and hold it securely during the molding process. The cooperating cam surfaces on the foot members and the surrounding sleeve create a hoop tension in the bushing which must be overcome to pivot the foot members to open position at completion of the molding process.Type: GrantFiled: May 13, 1980Date of Patent: September 22, 1981Assignee: Investigacion Fic FideicomisoInventor: Armando N.
